Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] In the embodiment of the present invention, the key frame close to the jump time point requested by the user is searched, and the 2 B frames at the starting position of the group of pictures containing the key frame are discarded, and the frame at the starting position in the group of pictures is discarded. The positions of the 2 B frames are filled with 2 empty frames, and the processed image group is used as the sending position of the new media data to send the media data.

Abstract

The invention is appropriate for the field of multimedia data processing technology, where jumping method of network interactive programme on demand, a system and a server for the same are provided. The method comprises the following steps of searching for a key frame similar with a jumping time point required by a user; performing discard processing of starting 2 frames B comprising a picture set of the key frame, filling positions of the starting 2 frames B with empty frames in the picture set; sending media data with the processed picture set as new media data sending position point. According to the invention, with said procedures, media data sent through the network and media data required by the user are more accurate on time, which effectively resolve screen tearing phenomena when jumping broadcast.

Description

technical field [0001] The invention belongs to the technical field of multimedia data processing, and in particular relates to a jump method, system and server for network interactive on-demand broadcasting. Background technique [0002] With the development of the network, the network interactive on-demand service has become a popular service. The existing interactive on-demand implementation is: according to the time point requested by the user, calculate the data position of the picture frame corresponding to the time point, then stop the original network transmission of media content, and start sending media content from the new position. Because the frame data of MPEG2 has a contextual correlation, the frame data at the new playback position cannot find the associated previous frame data, and a frame decoding error may occur on the set-top box end, causing the picture to be blurred. Contents of the invention [0003] The purpose of the embodiment of the present inve...
