Abstract

The present invention relates to an apparatus for implementing video-on-demand quick switching among multiple screens. The apparatus comprises a client, a state maintenance unit, a playing switching control unit, a medium content service unit. The client is used for initiating a playing switching request to the playing switching control unit, receives a control instruction sent by the play switching control unit, and implementing functions comprising content caching, content playing and caching stopping. The state maintenance unit is used for maintaining online sate information of clients and maintaining a binding relationship among the clients. The playing switching control unit is used for responding to the playing switching request of the client, determining a possible reception client of the playing switching, and controlling the client to implement functions comprising content caching, content playing and caching stopping. The medium content service unit is used for responding to a video service request of the client, searching, according to content location information carried in the request, for a GOP in the location, and providing a video service starting from a first frame of this GOP.

Description

technical field [0001] The invention relates to the field of interactive television, in particular to a device and method for realizing fast video-on-demand switching among multiple screens. Background technique [0002] The cable TV network is the main channel for the majority of users to watch TV programs at present. Early cable TV networks only allowed users to watch TV programs passively. With the development of related technologies, existing cable TV networks also provide users with on-demand functions, that is, users can order TV programs according to their own hobbies. Interaction between TVs. [0003] Multi-screen interaction is a form of interactive TV, which has developed rapidly in recent years and is favored by the majority of users. Specifically, multi-screen interaction means that different operating systems and different terminal devices can be compatible with each other across operations, and realize the transmission and synchronization of digital multimedi...
