The right claimed in the present invention is a triangular model based multimedia file flow control mechanism.

8. FIG. 8 is a diagram illustrating a triangular relationship model-based multimedia file flow control mechanism described with reference to FIG. 7.

FIG. 9 is a flowchart illustrating an outline of a control flow for multimedia contents having a triangular relation as one of the representative structural diagrams. This figure can select or terminate relationship A, B, or C at Start. In this case, the services include all multimedia content moving services including streaming, download, upload, live broadcast, preview, preview, sample download, mobile device type download, gift transmission, and other device transmission. It is possible to select different services by connecting to PC or Server at the initial screen of mobile device. This figure shows a specific processing flow for the content described in FIG.

As wireless mobile devices and wireless communication-based environments evolve, they can instantly and accurately acquire information, search for, watch, listen to, or purchase digital content (music, movies, pictures, animations, games, documents, etc.) regardless of location or environment. The need is gradually increasing.

These multimedia services include various free services such as multimedia contents online e-commerce services (including multimedia auctions), streaming services for movies, music multimedia contents with sequential file access characteristics, streaming of irregularly connected forms such as games, data, It can be divided into a mixed voice service. The present invention relates to all of these, and attaches importance to the mutual role between triangular members (M: Mobile Devices, Desk-top Computers, Service Provider) which will be described later, regardless of the transaction method or the format of the data. Collectively, these services include multimedia services (including streaming, download, upload, live broadcast, preview, preview, preview, sample download, download by mobile device type, send gifts, send other devices, etc.). Call it).

In the wired Internet environment, multimedia services for large files ranging from several megabytes to hundreds of megabytes are supported in various ways. However, in a wireless communication environment, a multimedia service provider and a user of a multimedia content are concerned about the quality deterioration of content use from different angles, and in particular, a user may take it for granted to receive a service that is reasonable for the price paid by the user. . First, the multimedia service provider intends to provide high-quality contents of the company even in a state where the frequency of access is very high and the wireless network which is less reliable than the wired Internet. In addition, a multimedia content user wants to be provided with high-quality content from a service provider even in a wireless access environment.

For example, when you want to watch a movie over a wireless connection, the service provider is responsible for providing quality service while the wireless streaming service is in progress, and effectively conducts long transactions (transactions that take a long time to start and end a transaction). In addition to handling, at some point, service reliability and throughput must be maintained for multiple subscribers even in situations where service concurrent access is exceeded. On the contrary, the multimedia service beneficiary wants to use the streaming service without any inconvenience so as to be consistent with the cost paid at all times, regardless of the service provider's situation. However, in this environment, server limitations result in another limitation situation.

In order to effectively cope with such a situation, a method of restricting access to a service when exceeding a service simultaneous accessor processing limit or a method of implementing a service by reducing a bandwidth or a customer compensation policy appropriate to a situation may be established. We are solving the problem either policyally or temporarily.

An object of the present invention is to propose a new processing method for satisfying a need for searching, viewing, listening to, or purchasing a large multimedia file in a communication environment connected using various wireless mobile devices.

Existing methods have limitations in that all subscribers receive large files, such as multimedia files, from a multimedia content service provider on-demand. Our method is largely based on three ideas:

First, take advantage of the processing power of a high-performance home computer at home as a multimedia streaming server.

Secondly, the mobile device is to be a beneficiary of the streaming service and at the same time play the role of a controller that manages the processing flow of multimedia content online commerce and uploads / downloads of the content.

Third, his multimedia home streaming server has a method of prohibiting all mobile access except the owner's access. In other words, it is different from the existing server and the proposed home server in that only mobile devices registered in the home server are targeted for service, excluding the multi-service concept of the existing server.

Existing patents provide streaming services to mobile devices by connecting to home PCs, receiving file transfer services to their mobile devices by connecting to home PCs, manipulating files on remote PCs, and simple computing functions for remote PCs. Has a patent right.

It is another aspect of the present invention to provide a management and transmission software architecture for achieving the purpose of controlling the transfer direction of a large file in a mobile device through a triangular client-server intercommunication communication structure implemented using a socket. Is to suggest. In other words, rather than unilaterally searching, transmitting, or streaming on one side, the triangular correlation entities form a client-server relationship by utilizing the mobile device as a remote remote controller.

That is, the present invention, like the existing method, simply runs, terminates, operates an application already existing on the home PC (Internet Explore, MS-Word, HWP, MSN, etc.), or transmits a file to a mobile device such as a mobile phone, It is not an existing technology for streaming, but a patent for a structure of software specially designed for the purpose of freely remotely controlling the direction of transmission of a large file larger than its size.

Features of the method can be described through the flow of control described in FIG. Through the authentication process, a mobile device secured to a server or a home PC can be selectively connected to a server or a personal home PC that has a copyright on the multimedia file, and the transmission direction of a large multimedia file can be steered. The reason why this is necessary is that the download (other service including upload) of the mobile device is not appropriate or the download (other service including upload) from the server to the mobile device due to the storage space limitation of the mobile device. If not, we propose an optional download (other service including upload) from server to home PC (other service including upload). Through the present invention, a specific processing flow having a client-server structure using a socket that can remotely control the direction of download (or other services including upload) by moving away from the method of simply using the home server as a streaming server. The control software must be applied, and to this end, it claims that the software configuration method is different from the existing invention.

Conventional techniques belonging to the field of the invention are represented in figures 1-4. In FIG. 1, independent desk-top computers 1 to n shown in the drawing are connected to a multimedia content service provider through wired / wireless internet connection in various ways, such as streaming service, download service, preview service, and live broadcasting service. A method of receiving a multimedia content delivery service. In FIG. 2, the independent mobile devices shown in the drawing are connected to a multimedia content service provider through various methods of wireless Internet connection to provide a wired / wireless multimedia content delivery service such as a streaming service, a download service, a preview service, and a live broadcast service. How to get In FIG. 3, the desk-top computer and the mobile devices include the wired / wireless computer and the mobile device group to receive the service described with reference to FIGS. 1 and 2 by a user communication request. 4 illustrates a peer-to-peer file sharing scheme. This conventional method is similar to the present patent, but the connection type is different from the proposed method because it uses n: m broadcasting method to share one file in infinite copy. In the present invention, the method described in FIGS. 1 and 2 is performed by 1: 1 secure communication between its home PC group and its mobile device group. In addition, although region A and region B described with reference to FIG. 5 have conventionally shared files, the present method has a feature that region A and region B are completely separated.

The present invention is a management and transmission software for achieving the purpose of controlling the transfer direction of a large file in a mobile device through a triangular client-server mutual communication communication structure implemented using a socket (socket) as an infrastructure for communication Suggest a structure. To this end, a new multimedia flow control S / W architecture is presented, and a processing flowchart (algorithm) of the method proposed by the present invention is proposed in FIG.

Mobile devices have lower capacity and lower performance processor power than home PCs. In this case, an idle home PC with relatively large storage and high performance processor power can be used as the subject of an e-commerce transaction and as a streaming server after the e-commerce, so that a wired online home PC can perform the main tasks to be performed on a mobile phone. have.

l Overcoming the difficulties of reliable download and upload to the server used as a trading market for the transactional multimedia contents created in the mobile phone. First, the multimedia content produced by the mobile device is transferred to an easy-to-access home PC or, conversely, the multimedia content is downloaded from a server. Multimedia content on a home PC is always easy to try to connect with the server, so that mobile devices no longer need to stay connected.

l For various types of multimedia services (all conceptually similar services such as downloading, uploading, streaming, re-broadcasting, and previewing multimedia content) (1) to be serviced by a service provider or (2) to be serviced from a home PC Is a method that can be determined, indicated, and controlled on various kinds of mobile devices.

l User's home PC group that does not allow connection of unauthenticated person when using multimedia service using his home PC: User's mobile device group is configured to have 1: 1 relationship. (The term group is due to the fact that you may have multiple home PCs or mobile devices.)

l The service provider's server has a connection capacity. The proposed technology utilizes the processing power of idle home PCs to enable infinite multimedia services.

The server of the service provider may have a disconnection of the streaming service even after access. That is, a drop in service quality. The concept of a multimedia home server is a technology that can prevent such a drop in service quality.

Although the conventional technology uses a one-to-many (1: n) method, the proposed method provides a personalization characteristic such as using a PC while moving.

l The service provider connects to the server every time through the authentication process through login and password, etc., but the proposed method is a technology that allows the connection from the mobile device to be smooth since the login procedure can be omitted because the device has already been authenticated. .

The proposed technology is a method that can be downloaded from the server of the service provider or a personalized connection to the multimedia contents owned by the service provider anytime, anywhere without restriction on the state of the server of the service provider.

The configuration of the present invention is described with the configuration of FIG. 7 and their operation is as follows.

Internet Connection includes all the technologies that make use of the various existing Internet data transmission networks.

l Relation A, B, and C are defined as triangular relations.

The objects controlled by these relationships are multimedia services (including all similar multimedia services such as streaming, downloading, uploading, previewing, streaming, and live broadcasting).

l For large files, upload and download from the home PC, not the mobile device, to the multimedia server.

For small files, it can be downloaded directly to the mobile device. However, control is provided to select this.

The mobile device can control how the multimedia service provider's server streams directly to the user's home PC and directly to the mobile device.

Each relation displayed in FIG. 7 will be described. This patent does not include processing scenarios containing control flows, but lists the actions taken in each relationship. (An arrow represents a control or flow of data.)

 Relationship A:

 M-> D: (1) access (2) send the created multimedia file to D, (3) navigate to D content, (4) order to register with D content S, (5) stream the content from D to M Command to do, (6) operation and command to e-mail the contents of D as attachment file

 S-> M: (1) Confirmation of authentication according to (1) above, (2) Check the status of M at any time, report the transmission status of S to M, and (3) M according to the file type selected by the command of M Download to (4) Stream to M according to the type of file selected by the command of M, (5) Download to D according to the type of file selected by the command of M, and send the processing result to M

The present invention is a management and transmission software for achieving the purpose of controlling the transfer direction of a large file in a mobile device through a triangular client-server mutual communication communication structure implemented using a socket (socket) as an infrastructure for communication Suggest a structure. To this end, a new multimedia flow control S / W architecture is presented. The control and the flow of multimedia data performed by the S / W structure as described above have the following application effects.

Mobile devices have lower capacity and lower performance processor power than home PCs. Therefore, an idle home PC with relatively large storage and high performance processor power is used as a streaming server after the subject of e-commerce and after e-commerce. In other words, let your wired online home PC do the main work for your phone.

l I want reliable download and upload to the server that is used as a trading market for the transactional multimedia contents created in the mobile phone. At this time, the biggest cause of the poor reliability is the download and upload capability of the server and the limitations of the communication environment. This difficulty is overcome as follows. First, the multimedia content produced by the mobile device is transferred to an easy-to-access home PC or, conversely, the multimedia content is downloaded from a server. Multimedia content on the home PC is always easy to connect to the server, and the mobile device no longer needs to stay connected.

Using this S / W structure, all multimedia services including streaming, download, upload, live broadcast, preview, preview, sample download, download by mobile device type, send gift, send other devices, etc. Content transfer service) can be determined, instructed, and controlled on various types of mobile devices (1) to be serviced by a service provider or (2) to be serviced at a home PC.

Using the S / W structure of this patent, as described in FIG. 5, a user's own home PC group that does not allow connection of unauthorized persons when using a multimedia service using his home PC: user's own It can be secure so that mobile device groups can have a 1: 1 relationship. In the conventional technology, the one-to-many (1: n) method is used, but the proposed method is a technology that provides personalization characteristics such as using a personal PC while on the move. You can also take advantage of 1: 1 in terms of connectivity. In other words, the service provider accesses the server every time through the authentication process through login and password, but the proposed method can be omitted since the login procedure can be skipped because the device has already been authenticated. have. Finally, such a 1: 1 connection has an advantage of allowing personalized access to the multimedia contents owned by the service provider, anytime, anywhere, anytime, anywhere, without restriction from the service provider's server.

The server of the service provider can overcome the limitation of the connection capacity. The proposed technology utilizes the processing power of idle home PCs to enable infinite multimedia services. In addition, the use of such processing power can prevent the deterioration of multimedia service quality.
