However, it should be understood that the following description does not limit the specific embodiments, but includes all changes, equivalents, and alternatives falling within the spirit and scope of the following description.
The terms first, second, A, B, etc., may be used to describe various components, but the components are not limited by the terms, but may be used to distinguish one component from another . For example, without departing from the scope of the following description, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component. And / or < / RTI > includes any combination of a plurality of related listed items or any of a plurality of related listed items.

Before describing the drawings in detail, it is to be clarified that the division of constituent parts in this specification is merely a division by main functions of each constituent part. That is, two or more constituent parts to be described below may be combined into one constituent part, or one constituent part may be divided into two or more functions according to functions that are more subdivided. In addition, each of the constituent units described below may additionally perform some or all of the functions of other constituent units in addition to the main functions of the constituent units themselves, and that some of the main functions, And may be carried out in a dedicated manner.
Also, in performing a method or an operation method, each of the processes constituting the method may take place differently from the stated order unless clearly specified in the context. That is, each process may occur in the same order as described, may be performed substantially concurrently, or may be performed in the opposite order.
The technique described below relates to a technique for providing a constant image to a display device. The display device refers to a device that reproduces or outputs a certain image such as a TV, a computer monitor, a projector, or the like. For convenience of explanation, it is described with reference to the TV. In offline TVs are sold in TV stores. The following description relates to a system or apparatus for providing a certain demonstration image to a TV displayed in the same place as a TV shop.
The demonstration image means the image that enables the customer to check the reproduction quality of the TV. On the other hand, the demonstration image should use the appropriate image according to the model and specification of the TV. There is a difference in color depending on the type of display (LCD, OLED, etc.) of the TV. Therefore, it is appropriate that the demonstration image can display the quality of the TV considering the display type. Furthermore, the demonstration image should be a video that matches the resolution of the TV. If a UHD (4K or 8K) TV is used, the image with UHD resolution should be used as the demo image. In this way, a more suitable demonstration image is required depending on the type and specification of the TV. At the current TV store, the manpower of the store provides individual demonstration videos for each TV. In this case, a demonstration video that does not match the characteristics of the TV may be reproduced. It is also preferable that a plurality of TVs reproduce the same image at the same time in the TV shop. It is easy for customers to compare different TVs. However, in the current TV store, it is difficult for the store manpower to provide the demonstration image manually and reproduce the exact same image at the same time.
The present invention relates to a demonstration image providing apparatus for a TV store, which can automatically provide a demonstration image suitable for a TV in a TV shop and simultaneously provide the same image to a plurality of TVs according to a user's setting. The following description will be made with reference to the drawings.
FIG. 1 shows an example of a store image providing system 100. 1 shows a TV displayed on a plurality of TV stores. In FIG. 1, the rectangular blocks A, B, and C denote different TV stores. Each TV store displays multiple TVs. The store image providing system 100 includes a memory device 110, a client device 150, and a management server 180.
The memory device 110 is a device that is physically connected to the TV 50. The memory device 110 may store image data. The TV 50 reads image data stored in the memory device 100, and outputs it to the screen while decoding. Most recently released TV 50 can decode video data on its own. The memory device 110 may be various devices such as a USB, an SD card, and a portable hard disk. The memory device 110 is physically connected to the TV 50. For example, a memory device 110 such as a USB or SD card may be inserted into the TV 50. A memory device 110 such as a portable hard disk may be connected to the TV 50 with a cable. For convenience of explanation, it is assumed that the memory device 110 is a device such as USB.
The memory device 110 is networked with the client device 150 located in the store. The network connecting the memory device 100 and the client device 150 can be roughly divided into a wireless network and a wired network. The memory device 110 and the client device 150 may be connected to each other in a wireless network or may be connected to a wired network in one store. In FIG. 1, store A is an example of connecting memory device 110A and client device 150A over a wireless network. In FIG. 1, store B is an example in which memory device 110B and client device 150B are connected by a wired network. Although not shown in FIG. 1, a wireless network and a wired network may be mixed in one store to connect the memory device 110 and the client device 150 together.
A wireless network between the memory device 100 and the client device 150 will be described in detail. In FIG. 1, store A is an example of connecting memory device 110A and client device 150A over a wireless network. In FIG. 1, the connection between the memory device 110A and the client device 150A is indicated by a dashed line and a symbol?. The connection between the other memory device and the client device 150A is denoted by?. Where the wireless network may be a local network operating within a store. Theoretically available short range networks are very diverse. As will be described later, the memory device 100 downloads a relatively large amount of image data from the client device 150. [ Therefore, it is preferable that the wireless network in the store has a high data transmission rate. For example, a wireless network such as a wireless LAN, Wi-Fi direct, or the like can be used. To this end, the memory device 100A and the client device 150A have a communication module for wireless communication to use. In the following description, the wireless network scheme between the memory device 110 and the client device 150 is not limited in a specific manner. However, for convenience of explanation, the Wi-Fi direct method, which is an inter-device wireless communication method, will be described. Wi-Fi Direct is a Wi-Fi standard that allows devices to connect easily without a wireless access point. Wi-Fi Direct ensures normal Wi-Fi speed and can communicate with more than one device at the same time. Since Wi-Fi Direct is an open standard, a detailed description of the technology is omitted.
A wired network between the memory device 100 and the client device 150 will be described in detail. 1, store B is an example in which memory device 110B and client device 150B are connected by a wired network (indicated by (1)). The wired network between the memory device 110B and the client device 150B may be any of a variety of types. For example, the memory device 110B and the client device 150B may be connected by a cable. If the memory device 110B is a USB, a so-called USB network can be configured. USB networks can share certain data with objects connected by cables. A dedicated driver for the USB network may be needed. Of course, the wired network scheme between the memory device 110 and the client device 150 is not limited in a particular way. For convenience of explanation, it is assumed that a wired network uses a USB network.
The client device 150 provides video data for a plurality of TVs in a TV shop. Basically, the client device 150 transfers the image data stored in its own storage device to the memory device 110. In another aspect, the memory device 110 downloads image data stored in the storage device of the client device 150. [ The video data sharing procedure will be described in detail later. The client device 150 also controls a plurality of TVs. Procedures for the client device 150 to control the TV will also be described later. On the other hand, a plurality of client devices 150 may be arranged in one store according to the number of TVs that one client device can handle.
The client device 150 is connected to the TV 50 via a wireless network. The client device 150 can transmit a certain control command through the network and can collect information from the TV 50. [ The wireless network between the client device 150 and the TV 50 may be one of a variety of wireless schemes. Typically, the wireless network between the client device 150 and the TV 50 may be a Wi-Fi based network. In FIG. 1, the connection between the TV 50 and the client device 150A is indicated by a solid line and a symbol ②. The connection between the other TV and the client device 150A is denoted by the reference sign (2).
The management server 180 manages each client device 150 disposed in a plurality of stores and monitors certain information. The client device 150 and the management server 180 are connected to a wide area network (WAN). For example, the client device 150 and the management server 180 may be connected to a PDN (Publid Data Network) such as the Internet. The client device 150 may be connected to the Internet via a wired port. The management server 180 may transmit a certain control command to the client device 150 disposed in each store. The management server 180 may collect certain information from the client device 150 and monitor the status of the entire system. The related description will be described later.
In the following description, it is assumed that the memory device 110 and the client device 150 are connected by a wireless network. Even when connected by wire, the operation according to the same procedure is performed.
FIG. 2 is an example of a process of providing images in the store image providing system 200. 2 is an example of a process of providing an image in one store. The in-store image providing system 200 includes memory devices 210A, 210B, and 210C and a client device 250. [ The client device 250 must first hold image data corresponding to the preview image. The client device 250 may include a storage device such as a flash memory or hard disk therein. In this case, the client device 250 downloads image data from another object (such as a server) or a computer device (PC, notebook, smart phone, etc.) connected to the network. Or client device 250 may be provided with image data from a removable flash memory device (e.g., USB). 2 illustrates an example in which an external memory device 255 such as a USB is inserted into the client device 250. [ The external memory device 255 stores certain image data. The external memory device 255 may store various kinds of images. The external memory device 255 may also store files having different resolutions (HD, 4K, 8K, etc.) for the same image.
The memory devices 210A, 210B, and 210C and the client device 250 in the in-store image providing system 200 may be connected to a Wi-Fi based network as described above. For example, the memory devices 210A, 210B, and 210C and the client device 250 may be connected to each other by Wi-Fi direct. The memory devices 210A, 210B, and 210C and the client device 250 may be connected using an AP (not shown). Or client device 250 may operate as an AP and may be coupled to memory devices 210A, 210B, and 210C.
2 is an example of a process of providing images to the memory devices 210A, 210B, and 210C. The memory device 210A will be described with reference to FIG. First, the memory device 210A and the client device 250 are connected to a Wi-Fi-based wireless network (①). The memory device 210A can acquire information on new image data stored in the storage device 255 of the client device 250. [ The memory device 210A accesses the storage device 255 of the client device 250 and can automatically download an image suitable for itself according to the identifier of the stored data (2). For example, the memory device 210A may automatically download a file containing a specific name based on the file name. Alternatively, the memory device 210A may automatically download a file stored in a folder containing a specific name based on the folder name. The file name or folder name can use the TV model name, resolution (4K, 8K, UHD, etc.), or a specific name set in advance.
The memory device 210A may request the client device 250 for information about the image data. The information on the image data includes an identifier of the image data, a content name of the image data, a format of the image data, a resolution of the image data, and the like. The memory device 210A may then check a specific image based on the information included in the response of the client device 250 and automatically download the image data stored in the storage device 255. [
Further, the client device 250 may send a specific file to the memory device 210A. In this process, the client device 250 requests information on the TV model and transmits specific image data matching the TV model to the memory device 210A. The process by which the client device 250 collects information on the TV model will be described later.
The memory devices 210B and 210C can also acquire image data of the storage device 255 through the same process.
3 is another example of a process of providing images in the store image providing system 200. 3 is a process of sharing image data stored in one memory device 210A with other memory devices 210B and 210C in the same store. The memory device 210A holds the video data A that is not stored in the storage device 255 of the client device 250. [ The memory device 210A is inserted into the TV 50 (1 & cir &). In fact, regardless of whether the memory device 210A is connected to the TV 50, the operation may be performed later. The memory device 210A and the client device 250 are connected to a Wi-Fi-based wireless network (2). The client device 250 may receive information about the content held from the memory device 210A. The client device 250 confirms that the memory device 210A holds the image data A that does not exist in the storage device 255. [ The client device 250 then requests the memory device 210A to download the image data A. [ The client device 250 downloads the image data A from the memory device 210A and stores it in the storage device 255 (3). 2, the other memory devices 210B and 210C can download the image data A from the client device 250. [ That is, the memory devices 210B and 210C and the client device 250 presuppose connection with a Wi-Fi-based wireless network (4). The memory devices 210B and 210C download image data stored in the storage device 255 (5).

Fig. The store image providing system 300 includes a memory device 310, a client device 350 and a management server 380. 4 shows an example in which the management server 380 delivers video data to the client device 350 of each store. The management server 380 transmits the image data to the store D as a reference. The management server 380 transfers the video data B to the client device 350 (1 & cir &). The client device 350 stores the image data B in an internal memory or an external storage device. Then, the memory devices 310A, 310B, and 310C can download the image data B from the client device 350 according to the process described with reference to FIG. The memory devices 310A, 310B, and 310C and the client device 350 are connected to a Wi-Fi-based wireless network (2). The memory devices 310A, 310B, and 310C automatically download the image data stored in the client device 350 (3). The client device 350 may store the image data B received from the management server 380 in an internal memory or an external storage device.
5 is an example of a process of providing an image according to a display model in the image providing system 400 for a store. 5 is an example of a process of providing an image according to a display model in one store. 5 is a process in which the client device 450 actively grasps a TV model and provides an image. The store image providing system 400 includes memory devices 410A, 410B, 410C and 410D and a client device 450. [ The memory device 410A connected to the TV 50A will be described as a reference. The memory device 410A is connected to the TV 50A. The TV 50A stores its model information in the memory device 410A (1 & cir &). The model information includes at least one of manufacturer information, a serial number of the TV, model information of the TV, support resolution information of the TV, and specification information of the TV. The memory device 410A and the client device 450 are connected to a Wi-Fi-based wireless network (2). The client device 450 may receive model information from the memory device 410A and collect information about the TV model (3).
The client device 450 also receives model information from the memory device 410B connected to the TV 50B, the memory device 410C connected to the TV 50C and the memory device 410D connected to the TV 50D via the same process Collect. When the client device 450 collects model information on the TV from all the memory devices 410A, 410B, 410C and 410D existing in the network, the client device 450 classifies the TV (or the memory device connected to the TV) according to the model information. 5 shows an example in which the client apparatus 450 classifies the TVs 50A and 50B into a model A group and classifies the TVs 50C and 50D into a model B group. (i) The client device 450 can classify TVs by the same model. The same model refers to products that have been given the same model name by the same manufacturer. The client device 450 may classify the model through the serial number or model number of the product. If video data is provided according to the model type, the TV can be classified according to the model. (ii) The client device 450 can classify the TV according to the type of the TV manufacturer. The client device 450 can classify the TV by the TV manufacturer through the serial number of the product or the manufacturer information. Since the performance or characteristics of the TV are different depending on the TV manufacturer, different image data may be provided depending on the TV manufacturer. (iii) The client device 450 can classify the TV according to the type of display panel (LCD, OLED, etc.) used in the TV. The client device 450 can classify the TV according to the display method through the serial number or specification information of the product. Since the characteristics of color and the like are different according to the display method, different demonstration images can be provided according to the display method. (iv) The client device 450 can classify the TV according to the resolution of the TV (HD, FHD, 4K, 8K, etc.). The client device 450 can sort the TV according to the resolution through the serial number of the product, the supported resolution information, or the specification information. Basically, it is preferable to use a demonstration image of the highest resolution that the TV can reproduce. Accordingly, the client apparatus 450 can provide image data according to the resolution of the TV.
Of course, the client device 450 may not classify the TV model in advance. The client device 450 may collect the model information and provide specific image data to the memory device according to the model.
The client device 450 provides the type A video data to the memory devices 410A and 410B connected to the TV belonging to the model A group (4). The memory devices 410A and 410B download the type A video data from the storage device 455 of the client device 450. [ On the other hand, the client device 450 provides the type B video data to the memory devices 410C and 410D connected to the TV belonging to the model B group (4). The memory devices 410C and 410D download the type B image data from the storage device 455 of the client device 450. [ Through this process, TVs belonging to the same group can play the same demonstration video.
6 is an example of a process of controlling image reproduction in the image providing system 500 for a store. 6 is an example of a process of controlling image reproduction in one store. 6 shows a case where the TVs 30A and 30B can not be controlled through the network. That is, in FIG. 5, the TVs 30A and 30B may be products without a network function. Or the TVs 30A and 30B may be products that can not use the home network function by the store environment. The store image providing system 500 includes memory devices 510A and 510B and a client device 550. [
The memory device 510A will be used as a reference. The memory device 510A and the client device 550 are connected to a Wi-Fi-based wireless network (1 & cir &). The memory device 510A downloads the image data from the storage device 555 of the client device 550 (2). The client device 550 transfers the control command for the image data to the memory device 510A. An administrator can deliver certain control commands to the memory device 510A through the input interface of the client device. Alternatively, the administrator may input a control command to the client apparatus 550 using the remote controller 80 (3 & cir &). The client device 550 transfers the command related to the video data reproduction to the memory device 510A (4).
The memory device 510A transfers the control command to the TV 30A (5). For example, memory device 510A may have an IR (infrared) transmitter and communicate control commands to TV 30A. Or the TV 30A may recognize the control command transmitted (stored) to the memory device 510A to reproduce the image. Meanwhile, the client device 550 can transmit control commands to the memory device 510B through the same process, and can control the operation of the TV 30B.
(i) the control command may be an instruction to immediately reproduce the image data stored in the memory devices 510A and 510B. Since the client device 550 and the memory devices 510A and 510B are connected via the local area network, when the client device 550 simultaneously or continuously transmits the playback command, the same demodulated image is displayed on the TVs 30A and 30B almost simultaneously Can be reproduced. (ii) The control command may be a playback command for specific image data among the image data stored in the memory devices 510A and 510B. In this case, the control command includes the identifier of the image data. (iii) the control command may be an instruction to reproduce the image data stored in the memory devices 510A and 510B at a specific time. In this case, the control command includes the playback start time. The TV 30A and the TV 30B may include a timer to confirm the current time. In this case, it is assumed that the timers are set to the same (or substantially the same) time for the two TVs 30A and 30B. If the control command includes the start time, the TVs 30A and 30B can start playing the corresponding video data at the set time. (iv) the control command may be an instruction to stop playback of the image data stored in the memory devices 510A and 510B. In this case, the control command may include a playback stop time. (v) The control command may be a program list for recreating the demonstration image. The program list may include at least one of an identifier of image data, a time at which each image data starts to be reproduced, a time at which reproduction ends, and a position at which reproduction is started. In this case, the TVs 30A and 30B can reproduce the same contents according to a predetermined time schedule according to the set program. Alternatively, the TV 30A and the TV 30B may reproduce different contents according to a predetermined time schedule.
7 is an example of a process of controlling image reproduction according to the display model in the image providing system 500 for a store. Fig. 7 is an example of controlling image generation according to the display model in one store. FIG. 7 shows a case where the TVs 30A, 30B, 30C, and 30D can not be directly controlled through the network as shown in FIG. The store image providing system 500 includes memory devices 510A, 510B, 510C, and 510D and a client device 550.
First, the client device 550 classifies TVs existing in the network according to models. The memory device 510A connected to the TV 30A will be described as a reference. The memory device 510A is connected to the TV 30A. The TV 30A stores its model information in the memory device 510A (1 & cir &). The model information includes at least one of manufacturer information, a serial number of the TV, model information of the TV, support resolution information of the TV, and specification information of the TV. The memory device 510A and the client device 550 are connected to a Wi-Fi-based wireless network (2). The client device 550 may collect model information from the memory device 510A (3).
The client device 550 also receives model information from the memory device 510B connected to the TV 30B, the memory device 510C connected to the TV 30C and the memory device 510D connected to the TV 30D through the same process Collect. When the client device 550 collects model information on the TV from all the memory devices 510A, 510B, 510C and 510D existing in the network, the client device 550 classifies the TV (or the memory device connected to the TV) according to the model information. 7 shows an example in which the client apparatus 550 classifies the TVs 30A and 30B into a model A group and classifies the TVs 30C and 30D into a model B group.
Of course, the client device 550 may not classify the model in advance. When the client device 550 collects the model information and receives a control command according to the model, the client device 550 may transmit the control command only to the memory device connected to the specific TV model according to the control command.
The client device 550 provides image data to the memory devices 510A, 510B, 510C and 510D (4). The memory devices 510A, 510B, 510C, and 510D download image data from the storage device 555 of the client device 550. [ Depending on the model group, the memory devices 510A, 510B, 510C, and 510D may download different image data from the client device 550. [
The client device 550 transfers the control command for the image data to the memory device. As described above, an administrator can transmit a certain control command to the memory device through the input interface of the client device 550. [ Alternatively, the administrator may input a control command to the client apparatus 550 using the remote controller 80 (step 5). At this time, the control command is a command for a specific model. For example, the control command may be a command for TVs 30A and 30B belonging to the model A group. The client device 550 may check whether there is information on the model in the control command, and if there is information about the specific model (or the model group), the client device 550 may transmit the control command only to the corresponding model. 7 shows an example in which the client device 550 transmits commands related to image data reproduction to the memory devices 510A and 510B (6). The memory devices 510A and 510B transmit control commands to the TVs 30A and 30B (7). For example, a control command may be transmitted using infrared communication as described above. The TVs 30A and 30B can reproduce images according to a control command transmitted to the memory device 510B (8).
8 is another example of a process of controlling image reproduction in the image providing system 600 for a store. Fig. 8 is an example of controlling the image generation according to the display model in one store. The TVs 40A and 40B are connected to the home network and can be controlled. The store image providing system 600 includes memory devices 610A and 610B and a client device 650. [
Will be described with reference to the TV 40A. The memory device 610A and the client device 650 are connected to a Wi-Fi-based wireless network (①). The memory device 610A automatically downloads image data from the storage device 655 of the client device 650 (2).
The TV 40A and the client device 650 are connected through a home network. It is assumed that the TV 40A and the client device 650 use the UPnP (Universal Plug and Play) protocol. UPnP is a protocol used by DLNA (Digital Living Network Alliance). UPnP is also used as a protocol for home networks and the like. The UPnP will be briefly described below.
UPnP supports protocols such as TCP / IP, HTTP, HTTPU, HTTPMU, SSDP, GENA, SOAP, and XML. (1) TCP / IP serves as a basis for establishing the UPnP protocol. In other words, TCP / IP encapsulates the UPnP protocol and guarantees the order of transmission and reception. (2) HTTP, HTTPU, and HTTPMU are protocols that support unicast and multicast. HTTP is based on TCP / IP and HTTPU and HTTPMU are based on UDP / IP. (3) SSDP defines how to search network services on the network. The SSDP is built on top of HTTPU and HTTPMU and defines how the control point retrieves the desired resources on the network and how the devices are informed that they are available on the network. The client device 650 transmits the SSDP based on the multicast HTTPMU upon network connection. The TV 40A receives the SSDP and transmits the SSDP based on the unicast HTTPU if the search condition is satisfied. The TV 40A may transmit information informing its usable state through the GENA. The SSDP may also set the available time of the device due to the presence of a time stamp. (4) GENA provides the function to send and receive notifications of the device. UPnP uses the GENA format to generate presence announcements, sends them through the SSDP protocol, and notifies the UPnP event service of the service status change. The client device 650 may send a request that includes the desired service, the event send location and the event notification subscription time. (5) SOAP defines the usage of XML and HTTP to execute remote procedure calls. UPnP uses SOAP to send control messages to devices and returns the results and error history to the control point. A UPnP control request is a SOAP message containing an action to be performed and a set of parameters. For example, the client device 650 may deliver a control command to the TV 40A. Or the TV 40A may request certain information from the client device 650. [
UPnP networking consists of addressing, discovery - advertisement, description, control, and eventing. (1) In addressing, each device is assigned an address when connecting to the network. If a DHCP server exists, the address is automatically assigned. If no DHCP server exists, Auto IP is used. (2) When an address is assigned to a new device, this device informs the control devices on the network of its connection status. For example, the TV 40A can notify the client device 650 of its connection status. The client device 650 may multicast the SSDP discovery message to retrieve the attached memory device. TV 40A receives the message and responds if it matches the search condition. (3) The response by the search request includes a URL that provides the device description. The client device 650 performs an HTTP GET request and the device sends device instructions. In this way, the client device 650 can acquire information about the TV 40A connected to the network. (4) The control point can control the device through the control URL of the device. For example, the client device 650 may perform certain control over the TV 40A. (5) The device can transmit its change state to the control point on the network registered in its event. In other words, the TV 40A can transmit its own status information to the client device 650. [
The TV 40A and the client device 650 recognize each other based on UPnP (3). The process of recognizing includes a process in which the TV 40A is allocated an address on the network and informs the client device 650, which is a control device, of its own information. Through the recognition process, the client device 650 can collect information about the TV 40A.
The client device 650 transmits a control command for the video data to the TV 40A. An administrator can deliver a certain control command to the TV 40A through the input interface of the client device 650. [ An administrator may input a control command to the client device 650 using the remote controller 80 (4). The client device 650 transmits a control command related to video data reproduction to the TV 40A (step 5). The TV 40A reproduces an image according to the received control command (6). Meanwhile, the client device 650 can transmit a control command to the TV 40B through the same process, and can control the operation of the TV 40B.
9 is another example of a process of controlling image reproduction according to the display model in the image providing system 600 for a store. FIG. 9 is an example of controlling image generation according to the display model in one store. FIG. 9 shows a case where the TVs 40A, 40B, 40C, and 40D can be controlled through the home network as shown in FIG. The store image providing system 600 includes memory devices 610A, 610B, 610C and 610D and a client device 650. [
The client device 650 classifies TVs existing in the network according to models. The memory device 610A connected to the TV 40A will be described. The memory device 610A is connected to the TV 40A. The TV 40A stores its model information in the memory device 510A (1 & cir &). The model information includes at least one of manufacturer information, a serial number of the TV, model information of the TV, support resolution information of the TV, and specification information of the TV. The memory device 610A and the client device 650 are connected to a Wi-Fi-based wireless network (2). The client device 650 may collect model information stored in the memory device 610A (3 & cir &).
On the other hand, the client device 650 receives the model information 610B from the memory device 610B connected to the TV 40B, the memory device 610C connected to the TV 40C, and the memory device 610D connected to the TV 40D, Lt; / RTI > When the client device 650 collects model information about the TV from all the memory devices 610A, 610B, 610C, and 610D existing in the network, the client device 650 classifies the TV (or the memory device connected to the TV) according to the model information. 7 shows an example in which the client apparatus 650 classifies the TVs 40A and 40B into a model A group and the TVs 40C and 40D into a model B group.
Of course, the client device 650 may not pre-classify the model. When the client device 650 collects model information and a control command according to the model is transmitted, the client device 650 may transmit a control command only to a specific TV according to the control command.
The client device 650 provides image data to the memory devices 610A, 610B, 610C, and 610D (4). The memory devices 610A, 610B, 610C, and 610D download image data from the storage device 655 of the client device 650. [ Depending on the model group, the memory devices 610A, 610B, 610C, and 610D may download different image data from the client device 650. [
In addition, the TV 40A and the client device 650 recognize each other based on UPnP (5). The process of recognizing includes a process in which the TV 40A is allocated an address on the network and informs the client device 650, which is a control device, of its own information. Through the recognition process, the client device 650 can collect information about the TV 40A. For example, the client device 650 may collect model information of the TV 40A. The client device 650 can compare the model information collected from the memory device 610A with the model information collected from the TV 40A and confirm that the memory device 610A is connected to the TV 40A. For example, the client device 650 confirms the TV serial number included in the model information, so that the memory device 610A is connected to the TV 40A.
The client device 650 transfers control commands for the image data to the memory device. As described above, the administrator can transmit a certain control command to the memory device through the input interface of the client device 650. [ Alternatively, the administrator may input a control command to the client device 650 using the remote controller 80 (6). At this time, the control command is a command for a specific model. For example, the control command may be a command for TVs 40A and 40B belonging to the Model A group. The client device 650 can check whether there is information about the model in the control command, and if there is information about the specific model (or the model group), the client device 650 can transmit the control command only to the corresponding model. The client device 650 knows all of the information about the TVs 40A and 40B and the image data stored in the memory devices 610A and 610B. Thus, for example, the client device 650 may transmit an instruction to the TV 40A to reproduce specific image data among the image data stored in the memory device 610A. 9 shows an example in which the client device 650 transmits a command related to video data reproduction to the TVs 40A and 40B (7). The TV 40A can reproduce the image data stored in the memory device 610A according to the control command (8). The TV 40B can reproduce the video data stored in the memory device 610B according to the control command (8).
The client device 650 can deliver a command to simultaneously reproduce the same image to a plurality of TVs. Alternatively, the client device 650 may transmit an instruction to reproduce the same image for a plurality of TVs at different set times. Alternatively, the client device 650 may deliver commands to reproduce different images for a plurality of TVs.
Although not shown in FIG. 9, the client device 650 can also transmit a command for video reproduction to a TV belonging to the model B group. It is assumed that the TVs belonging to the model A group and the TVs belonging to the model B group have different resolutions or display methods. The client device 650 can deliver commands to all the TVs to simultaneously reproduce images meeting the resolution or display method. At this time, the reproduced image may be the same content (e.g., the same movie, etc.).
10 is an example of a process of monitoring a device in the in-store image providing system 700. Fig. 10 is an example of performing monitoring for a plurality of stores (store D and store E). Of course, the management server 780 may also monitor one store. The store image providing system 700 includes memory devices 710A, 710B, 710C, and 710D, client devices 750A and 750B, and a management server 780.
The TV displayed at the store D has no home network function or is in a state that it can not be utilized. The memory devices 710A, 710B, and 710C and the client device 750A are connected to a Wi-Fi-based wireless network (①). At this time, it is assumed that the memory devices 710A, 710B, and 710C respectively have model information for the connected TV. The model information includes at least one of manufacturer information, a serial number of the TV, model information of the TV, support resolution information of the TV, and specification information of the TV. Client device 750A requests certain information delivery to memory devices 710A, 710B, and 710C and receives information delivered by memory devices 710A, 710B, and 710C (2). The client device 750A can receive model information from the memory devices 710A, 710B, and 710C and information about the image data held by the memory device. Further, the client apparatus 750A may determine whether or not the TV is in operation (power on / off). For example, if the client device 750A recognizes the addressed memory device 710A in the network and then fails to deliver the message to the memory device 710A more than a predetermined number of times, the memory device 710A is powered off , It is possible to diagnose the state by the failure of the TV or the failure of the memory device 710A. The client device 750A can transmit the collected information to the management server 780 (3 & cir &).
The TV 40E displayed in the store D is controllable by the home network function. The memory device 710D and the client device 750B are connected to a Wi-Fi-based wireless network (4). At this time, it is assumed that the memory device 710D holds model information for the connected TV 40E. The client device 750B requests the memory device 710D to transfer certain information, and receives the information transmitted by the memory device 710D (5). The client device 750B can receive model information from the memory device 710D and information on the image data held by the memory device.
Meanwhile, the client apparatus 750B recognizes the TV 40E based on UPnP (6). The client apparatus 750B can request a certain information transmission to the TV 40E and receive the information transmitted by the TV 40E (7). The client apparatus 750B can receive model information, information on the currently reproduced image, information on the operation state, and the like from the TV 40E. The client device 750B can transmit the collected information to the management server 780 (8).
The manager can analyze the situation of each store by using the information collected through the management server 780. The management server 780 stores information on the currently reproduced video in the specific store, information (model name, number, etc.) about the TV in which the current video is reproduced, information on the TV in which the current video is not reproduced, Information about the memory device, and the like. The administrator can confirm the information provided by the management server 780 using the computer device. On the other hand, the management server 780 can provide specific image data to a specific client device as described in FIG. Furthermore, the management server 780 can forward specific control commands to the client device. For example, (i) the management server 780 can receive the information collection command for the specific store to the client device. (ii) The management server 780 may transmit a command related to the demonstration video reproduction to a specific TV of a specific store. The management server 780 may transmit schedule information about an image to be reproduced on a TV of a specific store.
