Below in conjunction with Fig. 5-Fig. 6, the video broadcasting method of the embodiment of the present invention is described.
Generally speaking, in the video playback side of the embodiment of the present invention, video player is responsible for providing online track relevant operating function to the user, comprises obtaining online and playing of track.The track server comprises the audio track files of magnanimity, and responsible maintenance management video file is to the mapping relations of track, with the track query requests of response video player.
As shown in Figure 5, from the angle of video player, the video broadcasting method of the embodiment of the present invention comprises:
51, video player is received user's query manipulation request.
The user finds that video file does not comprise own needed track, triggers the request of the online track of inquiry in the playing video file process.
52, video player calculates the check value of video file.
Video player calculates the check value of this video file after the query manipulation request of receiving the user.
Check value refers to the fingerprint of video file, can be based on obtaining such as the so conventional Hash calculation method of MD5, SHA-1, and check value possesses the function of this video file of unique identification.
The computational process of check value can be based on video file in full, can be also to take specific segmentation method calculating section segmentation Hash, and both are in difference slightly aspect the time, and integral body does not affect video file uniquely identified effect.
53, video player sends to the track server with check value.
Video player sends query requests to the track server, and query requests comprises the check value that calculates, so that the track server mates track by check value.
Optionally, query requests comprises the time span of check value and video, so that the track server is by the even individual dimension coupling of the time span of a check value and video track.To need sound to draw synchronous due to video playback, therefore, the time span of track usually and the time span of video can deviation too not large.
54, video player receives the track server and returns to the online track list that the match is successful.
Video player receives the track server and returns to according to relevant method the online track list that the match is successful, can comprise the essential informations such as audio track files title, category of language, time span in online track list.
Video player shows the user to check online track list.
55, video player receives user's play operation request, sends the download online request of audio track files to the track server.
After the user selected specific audio track files, video player sent the download online request of this audio track files to the track server.The download online process can be based on HTTP (the Hyper Text Transfer Protocol of routine, HTML (Hypertext Markup Language)) download, the track server provides transfer of data according to the HTTP standard, and support the mechanism that the segment request is downloaded, to satisfy the following multicast function in limit to the demand that drags of track.
56, video player separating video stream and audio stream.
Video player can carry out the separation process of video flowing and audio stream.
57, video player decoding and render video stream, replace with online track and abandon original audio stream.
Video player decoding and render video stream are abandoned simultaneously original audio stream, and are substituted just just-downloaded online track of decoding, and plays sound.Optionally, in the playing process of video flowing and audio stream, acquiescence is drawn synchronous effect according to the timestamp information of video and voice data thereby reach sound.
Optionally, video player is adjusted synchronous mode of operation for the user provides, when may there be nonsynchronous situation in the result of broadcast of Auto-matching, and video player response user's adjustment demand, and come into force in real time.Such adjustment of for example " track being delayed 0.5s (second) ".
As shown in Figure 6, from the angle of track server, the video broadcasting method of the embodiment of the present invention comprises:
61, the query requests of track server receiver, video player transmission.
Track server repository magnanimity audio track files is responsible for the maintenance management video file to the mapping relations of track.Obtaining and mapping relations of audio track files can be by completing under attendant's line, can be also by some user's active reportings mechanism, uploads all kinds of audio track files and matching relationship to server.
62, the track server returns to the online track list that the match is successful to video player.
The track server is when receiving the track query requests that video player is sent, the track server is corresponding video file check value in matching request at first, according to the video file of its local maintenance mapping relations to track, find audio track files set corresponding to this document.
When the track query requests of sending when video player comprises video time length, then, video time length and each audio track files of its preservation of comprising in track server contrast request are eliminated the too large audio track files of some time deviations from above-mentioned audio track files set.
The track server returns to video player with final audio track files set, as the audio track files set is returned to video player with the form of online track list.Because audio track files itself is larger, thus not direct foldback audio track files itself, but the essential information of qualified each audio track files is sent to video player.These essential informations comprise the information such as audio track files title, category of language, time span, file size, thereby judge and further select for the user.
63, the download online request of track server receiver, video player transmission.
After the user selected specific audio track files, video player sent the download online request of this audio track files to the track server.
64, the track server provides audio track files to video player.
For a common film, audio track files generally at tens MB (MByte, million) in 100 MB scopes.Download may need some times, so audio track files can be carried out the effect that the limit is broadcast below.
Particularly, audio track files itself is also the form of Media Stream, and the mode that namely can download by burst supports to download the effect of namely playing.And download the zone in the situation that the user drags to not, also can obtain corresponding document misregistration position according to the index of track inside, and continue from this position to download and the fragment of the audio track files of decoding.
Provide transfer of data as the track server according to the HTTP standard, and support the mechanism that the segment request is downloaded, to satisfy the following multicast function in limit to the demand that drags of track.
The above; only for the better embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
One of ordinary skill in the art will appreciate that all or part of flow process that realizes in above-described embodiment method, to come the relevant hardware of instruction to complete by computer program, described program can be stored in a computer read/write memory medium, this program can comprise the flow process as the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only store-memory body (Read-Only Memory, ROM) or random store-memory body (Random Access Memory, RAM) etc.
