Video traffic user distribution devices include Broadband Remote Access Server (BRAS), Digital Subscriber Line Access Multiplexer (DSLAM), LAN Switch, and the like.

The method of the present invention will be described below by referring to the system structure and basic steps for realizing multimedia services shown in FIG. Reference numerals 1 to 4 in Fig. 1 show four main steps of the method for realizing multimedia services of the present invention:

In the first step, the service service platform receives the on-demand request of the user terminal, and the service service platform can receive the on-demand request of the user terminal by providing the voice service, or can receive the on-demand request of the user terminal by providing the data service, and the user can conveniently utilize the broadband video terminal. The device transmits the on-demand request to the service service platform through the broadband network, the WEB server, etc.; or transmits the on-demand request of the user terminal directly to the service service platform through the communication network by using the telephone; or the user can use the broadband video business hall to submit the paper through the paper. The on-demand request of the user terminal transmits the on-demand request of the user terminal to the service service platform by the broadband video business hall through the telephone, various network terminals and the like.

The on-demand request of the user terminal may include: address information of the multimedia data to be played and user terminal information that needs to receive the multimedia data. The terminal information of the user terminal may be information such as a user name that uniquely identifies the user terminal in the broadband video system. The address information of the multimedia data to be played includes the name of the television program in the television program list provided by the service provider, the name of the multimedia data file that the user has submitted in various ways, and the like. The television programs that the user has submitted in various ways include television programs that have been submitted by the user in a broadband video business hall through a communication device such as a network terminal, or multimedia data files that the user has uploaded through the network terminal.

The on-demand request of the user terminal may also include: multimedia data that needs to be played and needs to be connected Receiving user terminal information of the multimedia data. When the multimedia data is carried in the on-demand request, the service service platform stores the multimedia data in a temporary program database according to a certain file format after performing security check on the multimedia data uploaded by the user terminal.

The user terminal provides the on-demand content provided by the present invention for the user terminal not only by the television provided by the service provider by carrying the multimedia data to be played in the on-demand request, or the multimedia data file submitted by the network terminal, the broadband video business hall or the like. The TV programs in the program list enrich the content of the TV program on demand.

In the second step, the service service platform obtains the multimedia data to be played directly from the on-demand request of the user terminal, or obtains the address information of the multimedia data to be played from the on-demand request of the user terminal, and saves the multicast video according to the address information. The multimedia data that the user terminal needs to play is obtained in the television program provided by the service provider in the source server or from the multimedia data file that has been submitted by the user terminal stored in the temporary program database.

The user terminal that needs to receive data includes: any one or more user terminals in the broadband video system. The user terminal that needs to receive data may also include a user terminal that transmits the on-demand request. When the user terminal that needs to receive data is a user terminal that transmits an on-demand request, the present invention can implement a multimedia service in which the user terminal orders the multimedia data provided by itself. When the user terminal that needs to receive data is another user terminal other than the user terminal that sends the on-demand request, the present invention can enable the user terminal to order the multimedia data provided by the user terminal or the television program in the television program list provided by the service provider. The multimedia service, such as the user terminal A in FIG. 1, can order the television program or multimedia data for the user terminal B.

In the third step, after the service data platform acquires the multimedia data that the user terminal needs to play and the user terminal information that needs to receive data according to the on-demand request, the service service platform determines the need to receive data by querying the correspondence between the user name saved by the user and the VLAN ID or the IP address. The VLAN ID or IP address of the user terminal, thereby further determining the video traffic user distribution device corresponding to the user terminal that needs to receive the data, and then the service service platform can directly play the required The multimedia data and the user terminal information that needs to receive the data are transmitted as an on-demand indication over the broadband network to the video traffic user distribution device corresponding to the user terminal that needs to receive the data; or the acquired multimedia data that needs to be played by the user terminal and the data to be received may be first received. The user terminal information is saved in a certain format. When the video traffic user distribution device actively acquires according to a predetermined setting, such as a predetermined time interval, the corresponding multimedia data that needs to be played and the user terminal information that needs to receive data are transmitted as an on-demand indication to The video traffic user distributes the device.

In the fourth step, the video distribution user distribution device corresponding to the user terminal that needs to receive the data plays the multimedia data to the user terminal that needs to receive the data.

The video traffic user distribution device is also allocated to the user terminal according to the broadband video system.

The VLAN ID or IP address determines the user terminal that needs to receive data.

The above is the basic step of implementing the multimedia service in the broadband video system of the present invention. In the actual application, when the user terminal sends the on-demand request, the playing condition of the playing multimedia data may be carried in the on-demand request and transmitted to the service service platform. The playback conditions can be: the time of playback and/or the number of repeated plays, and so on. The playing time is as the time of starting playback, the time period of playback, and so on.

After the service service platform obtains the play condition from the on-demand request, the on-demand indication should be constructed according to the play condition, and the on-demand indication includes the play condition, the multimedia data to be played, and the user terminal that needs to receive the data. Then, when the playback conditions are met, the service service platform transmits the corresponding on-demand indication to the corresponding video traffic user distribution device. Alternatively, the video traffic distribution device may also actively obtain an on-demand indication that satisfies the playing condition from the service service platform according to a predetermined time interval.

For example, when the playing condition is only the time of starting the playing, when the current time of the system meets the start playing time set by the user terminal, the service service platform transmits the on-demand indication to the video traffic user distributing device corresponding to the user terminal that needs to receive the data. Of course, video traffic users The distribution device may also actively obtain a corresponding on-demand indication that the time of starting playback coincides with the current time from the service service platform according to the predetermined time interval.

When the playing condition is the number of repeated playing, when the number of times played for the user terminal does not exceed the number of repeated playing, the service service platform transmits the on-demand indication to the video traffic user distributing device corresponding to the user terminal that needs to receive the data. Of course, the video traffic user distribution device can also actively obtain the corresponding on-demand indication that the number of times of playing does not exceed the number of repeated plays from the service service platform according to the predetermined time interval.

When the playing condition is the time of starting the playing and the number of repeated playing, when the current time of the system meets the start playing time set by the user terminal and the number of times played by the user terminal does not exceed the number of repeated playing, the service service platform transmits the on-demand indication to the required time. The video traffic user distribution device corresponding to the user terminal receiving the data. The video traffic user distribution device can also actively obtain the corresponding on-demand indication that the time to start playing is consistent with the current time and the number of times of playing does not exceed the number of repeated plays according to the predetermined time interval.

On the business service platform, setting the play time and repeat play times can be achieved by setting the corresponding timer and counter, respectively.

After receiving the on-demand indication sent by the service service platform, the video traffic user distribution device plays the multimedia data to be played included in the on-demand indication to the corresponding user terminal according to the user terminal information included in the on-demand indication that needs to receive data.

After receiving the on-demand indication transmitted by the service service platform, the video traffic user distribution device may first determine the play form according to the type of the multimedia data to be played included in the on-demand indication, and then play the multimedia data to the corresponding user terminal according to the play form. For example, the audio type multimedia data is played by audio, the text type multimedia data is played by subtitles, and the video type multimedia data is played by video. Alternatively, the video-type multimedia data can be played by the picture-in-picture method, so that the user terminal receiving the data can receive the on-demand multimedia data without switching the currently watched video program, which enriches the multimedia data. The way the media business is implemented.

Appropriate modifications can be made to the system and method in accordance with the present invention in a particular implementation to suit the particular needs of the particular situation. Therefore, it is to be understood that the specific embodiments of the invention described herein are merely illustrative and are not intended to limit the scope of the invention.
