Step 303, when described player end to described video stream data carry out downloading the duration of buffer memory exceed its preset largest buffered duration time, the time delay download request instruction that this player end generates with described unique identification information and preset delay duration is sent to described server end, described server end suspends according to the described video stream data transmission of this unique identification information extracted in this time delay download request instruction by correspondence, and recovers the transmission of described video stream data according to described delay duration.
The aforesaid operations how realizing the application is described with next application example.
First, if user wants to watch a certain Internet video, then player end obtains video address, and is added into by unique identification information in described video address, and the described video address with unique identification information is sent to server end as request address by player end.
Described video address, as http: // 116.212.117.220/demo.flv, this video address is effective address, a certain video stream data in corresponding server end.After described player end gets this video address, a unique identification information is increased at this video address end place, can be specifically parameter KEY, MD5 value etc., this unique identification information is generated by player end and the overall situation is unique, preferably, MD5 value is adopted in the present embodiment, suppose that this MD5 value is for 7674a31171f94e96a0d5682d59c55946, so, does described video address become http: // 116.212.117.220/demo.flv? key=7674a31171f94e96a0d5682d59c55946.Thus this video address with MD5 value is sent to described server end to ask video stream data as request address by described player end.
Second, the request address that player end described in described received server-side sends, from described request address, extract MD5 value mate with corresponding described video address and store, set up the corresponding relation of this MD5 value and this video address, then return corresponding video stream data according to this video address and be pushed to described player end.
Three, described player end carries out download buffer memory to described video stream data, and according to video cache duration preset in player end generate suspend resume request instruction be sent to described server end control described video stream data transmission time-out or resume.
Described player end, from this server end foradownloaded video flow data, carries out video playback simultaneously, and under the state that network environment is desirable, the speed of download, by the broadcasting speed faster than video, so has partial video data and is buffered.After the video duration arrival largest buffered duration of buffer memory (being assumed to be 5 minutes), more buffer memory only can waste the bandwidth of server end, therefore, described player end sends the request instruction with the time-out video flowing of MD5 value to described server end, does is this request instruction specially http: // 116.212.117.220/pause? key=7674a31171f94e96a0d5682d59c55946, after described received server-side to time-out request instruction, this corresponding video stream data is found according to MD5 value wherein, control described video stream data and suspend transmission, now, originally described video address http: // 116.212.117.220/demo.flv? key=7674a31171f94e96a0d5682d59c55946 just stops data-pushing.
Along with described player end constantly uses buffer memory to play, the duration of described buffer memory is lower than after described minimal cache duration, does player end send to described server end and resumes request instruction with MD5 value: http: // 116.212.117.220/resume? key=7674a31171f94e96a0d5682d59c55946, described received server-side is to after resuming request instruction, this corresponding video stream data is found according to MD5 value wherein, control described video stream data and enter normal download state, continue transmission.
