Processing method, system, set-top-box, and device for realizing synchronization of dialogue and media flow

Abstract

This invention discloses one synchronous process method to realize dialogue ad media flow. The invention method comprises the following steps: machine top case reports media flow status report to BMS to inform media servo discharge materials according to status report to offset dialogue. According to invention dialogue and media flow and top machine, it can get media flow current status to report media flow status report through case machine for integral management.

Description

technical field [0001] The invention relates to digital TV technology, in particular to a processing method, system, set-top box and device for realizing synchronization of session and media stream in digital TV. Background technique [0002] With the continuous advancement of my country's radio and television digitization process, it has become possible to use digital TV networks to carry out interactive services, and various interactive services continue to emerge. [0003] In the interactive service of the digital TV network, the typical processing process is: the user performs interactive operation through the guidance of the interactive electronic program guide (Electronic Program Guide, EPG), and the service request of the user is sent to the business management system (Business Management System) through the set-top box. , BMS), after a series of authentications, the BMS creates a session for the service request. The process of creating a session includes applying for...

Problems solved by technology

[0006] According to the above description, it can be seen that when the network or set-top box is abnormal, because the interactive EPG, or BMS, or media server cannot detect it, the synchronization control between the session and the media stream has a strong dependence on the outside. It can only be achieved by other means, for example, accessing the network management system, directly accessing network devices, etc. to obtain abnormal conditions of the network or set-top boxes, which affects the versatility of the implementation scheme for synchronizing sessions and media streams

In the process of synchronizing sessions and media streams, too much reliance is placed on the event notification interface between the BMS and the media server. The scope and granularity of events covered directly affect the effect of synchronizing sessions and media streams; and the event definition of the media server is still limited. There is no unified standard, and there are different event definitions for the capabilities of different media servers. In this way, the processing of BMS cannot be unified, which is not conducive to the integration between systems

[0007] In addition, in order to improve the effect of synchronizing sessions and media streams, it is necessary to require that event definitions cover as much content as possible, and the division granularity should be as fine as possible. On the other hand, BMS requires corresponding processing logic for each event. With the increase of the number of events and the finer granularity, the processing logic of BMS will be too complicated, and the implementation cost of BMS will be too high. High, and increases the processing burden of BMS

In addition, even if the granularity of event division is very fine, some events cannot be detected by the media server, so it is impossible to realize the synchronization between the session and the media stream through the corresponding event notification
