Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

101. acquiring target equipment parameter information, wherein the target equipment parameter information comprises: an identification of the target device; the target device includes: a transmitter for transmitting multimedia data and a receiver for receiving multimedia data.

When the transmitter and the receiver in the wireless audio-video transmission system need to be paired, so that the wireless audio-video transmission system can carry out audio-video transmission, the identifier of the transmitter and the identifier of the receiver can be obtained through the terminal equipment.

Wherein the identification of the target device comprises at least: a Media Access Control (MAC) address of the target device, and/or a name of the target device.

In an implementation manner, the terminal device may obtain the identifier of the transmitter and the identifier of the receiver through a wireless communication manner, and at this time, the transmitter and the receiver may carry their identifiers in a wireless signal to send to the terminal device.

Illustratively, the wireless communication means includes at least the following communication means: bluetooth, Wireless Local Area Network (WLAN), Wireless Fidelity (wifi), or Infrared.

Taking the wireless communication mode as an infrared mode, taking the wireless signal as an infrared pulse signal as an example: when the transmitter and the receiver in the wireless video transmission system need to be paired, the infrared function of the transmitter and the receiver is started, then both the emitter and the receiver send infrared pulse signals, the infrared pulse signals of the emitter carry the identification of the emitter, the infrared pulse signals of the receiver carry the identification of the receiver, meanwhile, the terminal device also starts the self infrared function, after the terminal equipment starts the infrared function, the terminal equipment can scan the infrared pulse signal, because the transmitter and the receiver both transmit infrared pulse signals, at this time, the terminal device will receive the infrared pulse signals transmitted by the transmitter and the receiver, and the terminal equipment acquires the identifier of the emitter from the infrared pulse signal of the emitter and acquires the identifier of the receiver from the infrared pulse signal of the receiver.

When the terminal device scans the infrared pulse signal, if there are some other devices with infrared function on site, the device also starts its own infrared function, for example: the terminal device receives the infrared pulse signals sent by the infrared devices, and then the infrared pulse signals received by the terminal device have the infrared pulse signals of the emitter, the infrared pulse signals of the receiver and the infrared pulse signals of other infrared devices.

At this time, as shown in fig. 3, the above 101 includes the following sub-steps:

1011: receiving device parameter information, the device parameter information comprising: a device identification of the device.

1012: and detecting an identifier corresponding to the target device in the device identifiers of the devices according to a preset rule.

1013: and acquiring the identifier corresponding to the detected target equipment as the parameter information of the target equipment.

In this disclosure, the device identifiers in specific forms are set for the transmitter and the receiver according to the preset rules, so that the device identifiers of the transmitter and the receiver can be distinguished from the device identifiers of other infrared devices, so that after the terminal device receives the device parameter information of all devices, the screening operation can be performed, the device identifiers corresponding to the transmitter and the receiver in the device identifiers of the device can be detected according to the preset rules, and then the device identifiers corresponding to the transmitter and the receiver are obtained from the received device identifiers, thereby preventing the terminal device from outputting the device parameter information of a non-transmitter and a non-receiver when the terminal device outputs the target device parameter information to a user.

Further, as shown in fig. 4, the step 1012 includes the following sub-steps:

10121: and detecting the equipment identification matched with the equipment identification formed by the preset coding mode in the equipment identification of the equipment.

10122: and taking the matched device identification as the identification of the target device.

For example, setting a specific device identification for the transmitter and the receiver may include: the device identifiers of the transmitter and the receiver are generated by using a preset coding mode, which is distinguished from the coding modes of the device identifiers of other infrared devices, and is unique, for example: the preset encoding mode may be that a preset bit in the device identifiers of the transmitter and the receiver adopts a special character identifier, or the preset encoding mode may be that a specific character is used as the beginning of the device identifiers of the transmitter and the receiver, or the preset encoding mode may be that a specific character is used as the end of the device identifiers of the transmitter and the receiver, and the like.

102. And outputting the parameter information of the target equipment.

and when the response information indicates that the receiver to be paired is successfully paired with the transmitter to be paired, storing the pairing relationship.

When the response information received by the terminal device indicates that the receiver to be paired is successfully paired with the transmitter to be paired, the pairing relationship may be stored, for example: the successfully paired receiver and transmitter may be connected by a straight line as shown in the graphical interface.

After the receiver to be paired and the transmitter to be paired are successfully paired, the pairing relationship is stored, so that a user can clearly see which transmitters and receivers are successfully paired, and the transmitters and receivers which need to be paired can be easily selected.

For a more clear description of the content of the present invention, the following description will take the example of the product vPixel (phantom) 2.0 of the wireless video transmission system as an example.

The vPixel (phantom) 2.0 product of the wireless video transmission system is mainly applied to meeting rooms, training rooms and workshop scenes, and can realize wireless transmission of screen pictures and audios and videos.

The vPixel2.0 product is a set of wireless video and audio transmission system, and comprises a receiver and a transmitter. The system deployment diagram can refer to fig. 1. The transmitter (S end for short) is mainly used for collecting, coding and sending video images; the receiver (R end for short) is mainly used for receiving, decoding and sending video images to the display for display.

Referring to fig. 1, the vPixel2.0 product adopts a WiFi display connection technology, and any terminal device that can be connected to the vPixel2.0 product can be projected through the vPixel2.0 product. That is, the transmitter acquires a video image from the terminal device, encodes the video image, transmits the encoded video image to the receiver, decodes the video image by the receiver, and transmits the decoded video image to the display device for display.

In use, a receiver needs to be connected to a transmitter, and the receiver can receive the display from the corresponding transmitter. However, one transmitter may be connected to a plurality of receivers at the same time, so that the transmitter may transmit a display screen to the plurality of receivers at the same time.

The existing receiver and the existing transmitter are connected in an infrared mode, the infrared function is started by default when the equipment is started, when the connection between the receiver and the transmitter needs to be established, a switching key of the transmitter is manually pressed, the infrared window of the transmitter is aligned to the infrared window of the receiver, and the receiver and the transmitter are paired one to one through infrared emission and reception.

However, the operation mode is not convenient and intuitive. Moreover, for some large-scale enterprise application scenarios, the number of receivers and transmitters used may be large, and in this case, it is also a time-consuming and labor-consuming task to manually connect one by one.

In order to solve the technical problem, the present disclosure provides an apparatus connection method in a wireless video transmission system, and by using the technical scheme of the present disclosure, the complicated steps of manual key pairing of a phantom series product and pairing of a plurality of transmitters and one or more receivers can be eliminated, so that the pairing of a transmitter end and a receiver can be efficiently and conveniently realized.

Moreover, in order to facilitate the operation in the terminal device, an Application (APP) may be built in the terminal device, and the user may operate the APP to perform the pairing operation of the receiver and the transmitter.

The method specifically comprises a device binding stage and a device pairing stage.

1) And a device binding stage:

the user opens the back through opening built-in APP among the terminal equipment, and infrared function is opened to this built-in APP to detect all equipment that open infrared function in the scene.

In this step, after the terminal device starts the infrared function, it can receive all the infrared pulse signals sent by the devices that start the infrared function on the site, where the infrared pulse signals include the MAC addresses of the corresponding devices.

The APP obtains MAC addresses of all detected devices with the infrared functions started.

Because the infrared pulse signal sent by the device with the infrared function is started carries the MAC address of the device, the APP can acquire the MAC address of each device after receiving the infrared pulse signals through the infrared module of the terminal device.

The APP screens out the transmitter and the receiver from all detected devices according to the MAC address, the transmitter and the receiver are used as devices to be paired and displayed on a user interface, the MAC addresses of the transmitter and the receiver are recorded, the devices to be paired are added into an available device list, and binding of the devices to be paired is achieved.

In this step, since the MAC addresses of the wireless audio-visual transceiving equipment (i.e., the transmitter and the receiver) are obtained according to the preset encoding mode, that is, the MAC addresses have a certain rule, it is possible to identify which MAC addresses belong to the transmitter and the receiver according to the rule.

After the device to be paired is identified, information of the device to be paired may be displayed on the user interface, where the displayed information includes but is not limited to: the MAC address.

Further, if the infrared pulse signal also carries the device name, the device name can be displayed on the user interface at the same time.

Further, if the infrared pulse signal does not carry the device name, the terminal device may also perform information interaction with the transmitter and the receiver through other wireless communication methods to obtain the device names of the transmitter and the receiver. For example: by way of WiFi.

In practice, the transmitters and receivers may be displayed in a very intuitive manner, for example, each device is displayed in the form of a device icon, and the devices are displayed in groups according to the type of device, i.e., whether it belongs to a transmitter or a receiver. The schematic diagram is shown in fig. 11, referring to fig. 11, the left side is a transmitter icon list, and the right side is a receiver icon list, and the specific positions of the corresponding icons are as follows: the left or right side or the upper or lower side displays information of the corresponding device, such as: device name and/or MAC address.

2) A device pairing stage:

APP in the terminal equipment receives pairing information sent by a user through an APP operation interface, wherein the pairing information comprises: a first MAC address of a transmitter to be paired and a second MAC address of a receiver to be paired;

the APP judges whether the type of the equipment to be paired meets the pairing requirement or not according to the pairing information, if not, prompt information is output to prompt that the selected equipment type is wrong and cannot be paired, and the user can reselect; if the requirements are met, the next step is carried out;

in this step, the meeting of the requirements means: two devices to be paired must be one of the transmitter and the other the receiver.

And the APP acquires the MAC address of the transmitter to be paired and the MAC address of the receiver to be paired from the pairing information.

And the APP sends pairing indication information to the transmitter to be paired according to the MAC address of the transmitter to be paired, and the pairing indication information carries the MAC address of the receiver to be paired.

When the transmitter to be paired receives the pairing indication information sent by the APP, the MAC address of the receiver to be paired, which is included in the pairing indication information, is acquired;

and the transmitter sends an infrared pulse signal to the receiver to be paired according to the MAC address of the receiver to be paired.

And when receiving the infrared pulse signal sent by the transmitter to be paired, the receiver to be paired is paired with the transmitter to be paired, and returns a response message to the transmitter to be paired.

And the transmitter to be paired confirms that the pairing is successful after receiving the response information, and returns a response message of successful pairing to the terminal device APP.

And the terminal device APP receives the response information, after the successful pairing is determined, the information of the transmitter to be paired and the receiver to be paired which are successfully paired is recorded in a local database, and meanwhile, the transmitter to be paired and the receiver to be paired are connected by lines on an APP display interface to show that the transmitter to be paired and the receiver to be paired have a pairing relationship.

Thus, after all devices are paired, the user can visually check the pairing relationship between all transmitters and all receivers through the APP display interface.

The solution according to the invention is illustrated below by means of a specific example.

The method and the device can be mainly realized by avoiding the complicated steps such as manual key pairing of phantom series products and pairing of a plurality of transmitters and one or more receivers, and can efficiently and conveniently control the transmitters and the receivers to be paired. Because the transmitter and the receiver of unreal image all are equipped with infrared sensor, present most cell-phones also have infrared function, consequently, can develop an APP at the cell-phone end, and the user opens the installation and opens the APP after, opens the infrared function of cell-phone, can all add all information (binding the mac address) of the transmitter and the receiver that will pair to the APP earlier.

Here, five transmitters and three receivers are taken as an example:

as shown in fig. 12, through the device binding phase in the foregoing embodiment, the APP of the mobile phone is added with: information of the emitter A, the emitter B, the emitter C, the emitter D and the emitter E; information of receiver 1, receiver 2 and receiver 3; the binding mac addresses of the transmitter A, the transmitter B, the transmitter C, the transmitter D and the transmitter E are macA, macB, macC, macD and macE respectively, and the mac addresses of the three receivers are mac1, mac2 and mac3 respectively.

After the information is added, if a user wants to pair the transmitter a and the receiver 1, the transmitter a and the receiver 1 can be selected in the APP, after the infrared of the transmitter a and the receiver 1 is started, the transmitter a can transmit own infrared pulse signals to the receiver 1 through the mac1 of the receiver 1, the receiver 1 can perform pairing operation after receiving the infrared pulse signals transmitted by the transmitter a, and after the pairing, the receiver 1 can transmit response information to the transmitter a, so that the transmitter a and the receiver 1 can be successfully paired. And the operating user selects the emitter B and the receiver 1 in the APP to realize the successful pairing of the emitter B and the receiver 1, and then sequentially selects the emitter C, the emitter D and the emitter E, so that the successful pairing of a plurality of emitters and one receiver is realized.

The same principle is that: after the transmitter A and the receiver 1 are clicked and successfully paired, the receiver 2 can be clicked again to realize the pairing of the transmitter A and the receiver 2, and the receiver 3 can be clicked again to realize the pairing of the transmitter A and the receiver 3, so that the successful pairing of one transmitter and a plurality of receivers is realized.

Then, the terminal device continues to perform the click to realize the pairing of the transmitter a, the transmitter B, the transmitter C, the transmitter D, the transmitter E and the receiver 2, and then continues to perform the click to realize the pairing of the transmitter a, the transmitter B, the transmitter C, the transmitter D, the transmitter E and the receiver 3, and finally, the schematic diagram displayed to the user by the terminal device is as shown in fig. 13.
