It should be noted that, the function of above-mentioned video information process server can as shown in Figure 2, realize by the server of independent setting, also its function can be integrated in media server and realize, and this embodiment of the present invention is not limited.
Referring to Fig. 3, for the invention provides the second embodiment flow chart of method of preview video, this embodiment, in conjunction with the system architecture shown in Fig. 2, shows in detail the process that preview video is provided:
Step 301: playback terminal sends video request to media server.
When having selected the list of videos that the user of playback terminal side presents from playback terminal interface after the video of wanting to play, playback terminal sends video request to media server, the mark that has comprised user-selected video in this video request, so that media server can find corresponding video according to this mark.
Step 302: media server finds video according to video request, and this video is handed down to playback terminal.
In the video source memory module of media server, video is index stores according to video labeling conventionally, therefore from video request, obtain after video labeling, can find corresponding video according to this video labeling, the video request of media server response playback terminal, is then issued to playback terminal by video distribution module by the video finding.
Step 303: playback terminal receives after the response of media server, sends metadata request to media server.
Playback terminal receives after the response of media server, presentation medium server can normally issue to playback terminal the video of its request, now playback terminal sends metadata request to media server, to obtain the metadata information of this video from media server side.
Metadata information is the information for describing certain characteristic attribute of video, for example, can be the temperature information of video, review information etc., and metadata information can be to exist with XML file format, or other form that can present with textual form exists.Metadata information can be according to the information acquisition of the user feedback of playback terminal, also the statistical information that can make according to third party obtains, for example, video vendor has provided certain performer concrete time period occurring in video, also can be that media server carries out the information generating after analyzing and processing to video, for example, media server can detect the time point that in video, each taking lens switches, and generates the metadata information of corresponding camera lens point switching time.
Suppose that metadata information is the statistics of the review information of user to video, the example of a metadata information is as follows:
In above-mentioned metadata information, Chunks represents the burst number of certain video, Dur represents the time span (can in seconds) of each burst, n represents the burst number of video slicing, it is which burst, h represents the quantity statistics that user comments on this video slicing, and numerical value is larger represents that the number of times of being commented on is more.Taking metadata information as XML form is as example, the size of each metadata information is about 70kB/H.The main video packets that above-mentioned metadata information is corresponding has contained 10 bursts, and each burst has different comment numbers, and the comment number that wherein burst 1, burst 2 and burst 6 obtain is maximum, is 100.Known according to number of reviews, watched the user of this main video larger to the interest of burst 1, burst 2 and burst 6, can set above-mentioned burst 1, burst 2 and burst 6 is focus fragment.
Step 304: media server obtains the metadata information that playback terminal is asked from video information process server.
The metadata information of video can leave in the independent video information process server arranging conventionally, in the time that media server receives metadata request, from video information process server, obtain the metadata information of this video according to the video labeling of the corresponding video of this metadata request.
Step 305: metadata information is sent to playback terminal by media server.
Step 306: playback terminal, by analysis of metadata information, obtains the request order of preview video.
Playback terminal receives after metadata information, can analyze this metadata information, and analysis result is presented on the interface of playback terminal with the form of chart.For example, in the time that the metadata information receiving is the review information to main video shown in abovementioned steps 303, can be taking burst number as abscissa, taking comment number as ordinate, show each burst number corresponding comment number by column information, user can know which burst video is focus burst video according to this column information, and these focus burst information are as preview video, subsequent user may have been downloaded after these preview video at playback terminal, and preview is in advance to these burst videos.
Still be example taking metadata information as review information, playback terminal, before request preview video, first will be determined the request order of preview video.For example, playback terminal can be determined request order according to the comment number of burst video order from high to low, for the identical burst video of comment number, can be further determines request order according to burst order number from small to large.According to above-mentioned request principle, suppose that playback terminal need to ask four preview video, request order is followed successively by burst 1, burst 2, burst 6, burst 5, and each burst can be used as a preview video.Hence one can see that, in the embodiment of the present invention, the downloading order of preview video and the reproduction time of main video order do not have correlation, only relevant with the result that metadata information is analyzed, so that playback terminal can be downloaded preview video in advance, in the time that preview video is watched in user's request, needn't wait for, promote user and experience.
Step 307: playback terminal judges that whether the video that request is play meets default broadcasting condition, if so, performs step 308; Otherwise, return to step 307.
Default broadcasting condition can refer to stable playback of video, for example, the video that playback terminal is downloaded has been play 10s, or the playback terminal progress of foradownloaded video has exceeded current playing progress rate and has reached certain threshold value (such as threshold value is 30s, currently be played to 50s, and downloaded to 100s).
Step 308: playback terminal sends preview video request according to request order to media server.
Playback terminal is according to the aforementioned request order analyzing, and order is to media server request burst 1, burst 2, burst 6, burst 5.
Step 309: asked preview video is issued to playback terminal by media server.
Media server, in the time issuing preview video, still issues according to the request order of preview video, and order issues burst 1, burst 2, burst 6, burst 5.
In the process of video downloading and playing, if can maintaining, the download progress of video plays a period of time, and for example, it is 100s that a time threshold is set, and media server can preferentially issue preview video to playback terminal, and then issues follow-up video.
Step 310: playback terminal, in presenting the video of request broadcasting, presents the preview video having received according to user instruction.
Terminal is in the process of video that presents request broadcasting, and the preview video comprising for the later video section of the current download progress of video, can obtain and carry out preview in advance.For example, when user when the preview video position on progress bar, can present mouse-over in the content of preview video in wicket, watch for user.
