Embodiment 1

[0098] Embodiments of the present invention provide a video playback method, which is applied to a multimedia system (the multimedia system includes a media gateway, a set-top box, and at least one media server), and the execution subject is a media gateway, such as figure 2 As shown, the method includes the following steps:

[0099] 101. Search for each video segment of the video to be played in at least one media server.

[0100] Here, each video segment is a video segment of a different format. Of course, the embodiment of the present invention is not limited to this video segment, and each video segment may also have the same format (for example, both are in TS format). In a word, the embodiment of the present invention aims to realize the continuous playback of arbitrary video segments, avoiding the continuous playback of video segments in TS format as in the prior art.

[0101] Since the multimedia system provided by the embodiment of the present invention includes a m...

Embodiment 2

[0163] The embodiment of the present invention provides a video playback method, which is applied to a multimedia system, such as image 3 As shown, the method includes the following steps:

[0164] 201. The media gateway searches at least one media server for each video segment that matches the program information of the video to be played, and determines each video segment that matches the program information of the video to be played as each video segment of the video to be played . And obtain the playback information, address information, and decoding parameters of each video segment of the video to be played respectively.

[0165] Wherein, the playing information of the video segment includes: duration information, start time, end time, and program information of the video segment. Each video segment of the video to be played may be a video segment with a different format.

[0166] The media server in the multimedia system provided by the embodiment of the present inve...

Embodiment 3

[0227] An embodiment of the present invention provides a media device 3, which is deployed in a multimedia system, and the multimedia system includes: a media device, a playback device, and at least one media server, such as Figure 5 As shown, the media device 3 includes: a search unit 301 , an acquisition unit 302 , a determination unit 303 , a generation unit 304 and a sending unit 305 .

[0228] The media server in the multimedia system provided by the embodiment of the present invention is a video server or a CDN server, so the media gateway can search a large number of video fragments. In a specific implementation, decoding parameters of these video slices are obtained, such as SPS / PPS (SequenceParameterSet, sequence parameter set / PPSPictureParameterSet, image parameter set) information required for H.264 decoder initialization. Wherein, each video fragment is a video fragment with different formats and originating from the same media server. Or, each video segment is a...

Abstract

The embodiment of the invention provides a video playing method, media equipment, playing equipment and a multimedia system, relating to the field of communication. The invention is used for realizing the continuous playing of video fragments in any format. The method comprises a step of searching each video fragment of a video to be played in at least one media server, a step of obtaining the playing information, address information and decoding parameter of each video fragment respectively, a step of determining the available video segments of continuous playing the video to be played and the sequence according to the playing information of each video fragment and generating a playing list comprising the address information and decoding parameter of each available video fragment according to the sequence, and a step of sending the playing list to the playing equipment such that the playing equipment finds the available video fragments according to the sequence and the address information, and the available video fragments are decoded and played by using the decoding parameter.

Description

technical field [0001] The present invention relates to the communication field, in particular to a video playing method, media equipment, playing equipment and a multimedia system. Background technique [0002] At present, a large number of video media file fragments are distributed on the Internet, and video portal websites and clients need to integrate each video media file fragment to realize seamless playback of video files. [0003] An existing HLS (HttpLiveStreaming, streaming media network transmission based on Http protocol) technology can divide the collected video resources into TS (TransportStream, transport stream) format video fragments, and distribute them to media servers in the network. Take the playback device composed of a media gateway and a set-top box as an example. When playing a certain video, the media gateway obtains the video fragments of each TS format of the video from the media server, and combines the video fragments according to different code...
