Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The main idea of ​​the present invention is: under the condition of normal network, the streaming media client terminal judges the video key frame. If the video key frame is not received within the set time, the streaming media client will make a key frame request and request the server to adjust the video key frame generation frequency. After receiving the request, the streaming media server will make a comprehensive judgment. According to the request of most clients during multicast or broadcast, or directly according to the client request during on-demand, the video key frame generation frequency is adjusted, and the corresponding video bandwidth requirement is adjusted.

[0028] In the streaming media service system, the present invention expands through the SET_PARAMETER METHOD (method) in the original RTSP (Real Time Streaming Prot...

Abstract

The invention discloses a method, a system and user equipment for obtaining key frames in streaming media services. Threshold time for receiving the key frames is set; a client receives video data from a streaming media server and analyzes the video data; when the network is in a normal state, and if the client does not receive a video key frame in the threshold time, a request for adjusting the generating frequency of the video key frame is sent to the streaming media server; and the streaming media server judges the received request and adjusts the generating frequency of the video key frame according to the request of the client. The application of the invention solves the problem that a user can fastest see clear video images when watching programs so that the user experience of the whole service is advanced at the larger limit.

Description

technical field [0001] The invention relates to the fields of communication and multimedia, in particular to a method, system and user equipment for acquiring key frames in streaming media services. Background technique [0002] With the development of communication technology, the communication bandwidth that can be provided to terminal equipment is increasing, multimedia has been developed rapidly on mobile terminals, and services such as mobile TV and streaming media are gradually becoming mature. However, these multimedia services mainly show their characteristics, and the integration of other services on these services has not been fully explored. [0003] How to enable users to see clear video images as quickly as possible when watching programs, so as to improve the user experience of the entire service to a greater extent, has become a problem that needs to be solved at present. Contents of the invention [0004] The technical problem to be solved by the present i...
