In the transmission of video request that video server receives, except the file identification that comprises the video file of asking transmission, also comprise this user's user profile and the facility information of this terminal equipment, after video server receives the transmission of video request, judge that whether the user profile of carrying in the transmission of video request be the user profile of authorized user, and whether the facility information that carries in the transmission of video request is the facility information of authorisation device, if judged result is be, confirm that then this user is authorized user, and this terminal equipment is authorisation device.
If it is that authentication is passed through that video server carries out the result of authentication process, then video server is according to the file identification that carries in the transmission of video request that receives, search video file corresponding to this document sign in each video file of storage, the stream of video frames that the video file that finds is corresponding is above-mentioned the first stream of video frames.
After video server obtains described the first stream of video frames, frame of video in this first stream of video frames is carried out out of orderization processing, wherein, to each frame of video in the first stream of video frames carry out out of orderization processing specific implementation can but be not limited to comprise following two kinds, the below is introduced respectively.
Out of orderization of the first processing mode is directly carried out out of orderization processing to all frame of video in above-mentioned the first stream of video frames, and the arbitrary frame of video in the first stream of video frames before namely out of order can appear at the optional position in the first stream of video frames after out of order.
Out of orderization of the second processing mode, at first according to frame of video in the first stream of video frames by the order after arriving first, each frame of video in the first stream of video frames is divided into each frame of video group, the number of included frame of video is identical in each frame of video group, this number can be predefined according to the performance of terminal equipment and player by video server, can be on terminal equipment continuously with stream of video frames, play smoothly and be benchmark, for example this number is set as 4, be to comprise 4 frame of video in each frame of video group, after video server is divided into each frame of video group with each frame of video in the first stream of video frames, for each the frame of video group that marks off, respectively each frame of video in this frame of video group is carried out out of orderization processing, be that arbitrary frame of video in this frame of video group in the first stream of video frames before out of order can only appear at the optional position in this frame of video group in the first stream of video frames after out of order, and can not appear in other frame of video groups.
Step 32 obtains the frame sequential information in first stream of video frames of each frame of video after out of orderization processing in the first front stream of video frames of out of orderization processing;
If video server adopts above-mentioned out of orderization of the first processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, namely directly all frame of video in above-mentioned the first stream of video frames are carried out out of orderization processing, then video server directly obtains the frame sequential information in first stream of video frames of each frame of video after out of orderization processing in the first stream of video frames before the out of orderization processing, the frame sequential information that namely each frame of video is correct;
If video server adopts above-mentioned out of orderization of the second processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, namely at first each frame of video in the first stream of video frames is divided into each frame of video group, for each the frame of video group that marks off, respectively each frame of video in this frame of video group is carried out out of orderization processing, when then video server obtains frame sequential information, first will be for each the frame of video group that marks off, obtain respectively the frame sequential information in each frame of video this frame of video group after out of orderization processing in this front frame of video group of out of orderization processing, the frame sequential information that each frame of video group that then will mark off is corresponding is defined as the frame sequential information in first stream of video frames of each frame of video after out of orderization processing in the first front stream of video frames of out of orderization processing.
For the time that can watch in the first stream of video frames the user is controlled, the embodiment of the invention two proposes, when video server adopts above-mentioned out of orderization of the second processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, if terminal equipment only has the authority of the partial video frame stream of playing in the first stream of video frames, then in first stream of video frames of described video server elder generation before out of orderization processing, determine the stream of video frames (i.e. the second stream of video frames) that this terminal equipment can be play, then in each the frame of video group that marks off, determine each frame of video group corresponding to described the second stream of video frames, again for each frame of video group of determining, obtain respectively the frame sequential information in each frame of video this frame of video group after out of orderization processing in this front frame of video group of out of orderization processing, the frame sequential information that each frame of video group of determining is corresponding is defined as the frame sequential information in first stream of video frames of each frame of video after out of orderization processing in the first front stream of video frames of out of orderization processing.
Wherein, determine the second stream of video frames process can but be not limited to following two kinds:
The first is determined mode: store the corresponding relation between facility information and the viewing time section in the video server, as shown in table 1:
Table 1:
Facility information The viewing time section
Terminal equipment
1 The 10th minute～the 20th minute
Terminal equipment
2 The 5th minute～the 15th minute
Video server is according to the facility information of this terminal equipment, in the said equipment information and the corresponding relation between the viewing time section of storage, search the time period that this terminal equipment can be watched in the first stream of video frames, and then according to the viewing time section that finds, determine the second stream of video frames;
The second is determined mode: store the corresponding relation between user profile and the viewing time section in the video server, as shown in table 2:
Table 2:
User profile The viewing time section
The user 1 The 10th minute～the 20th minute
The user 2 The 5th minute～the 15th minute
Video server is according to user's user profile, in the above-mentioned user profile and the corresponding relation between the viewing time section of storage, search the time period that this user can watch in the first stream of video frames, and then according to the viewing time section that finds, determine the second stream of video frames.
In the embodiment of the invention two, the correct frame sequential information of each frame of video in the frame of video group is the frame sequential information in each frame of video this frame of video group after out of orderization processing in this frame of video group before the out of orderization processing, for example: comprise 4 frame of video in each frame of video group, before out of orderization processing, the order of each frame of video in the frame of video group is:
Table 3:
1 2 3 4
After this frame of video group carried out out of orderization processing, the order of each frame of video was:
Table 4:
4 2 1 3
Suppose that a frame sequential information corresponding to frame of video group takies a byte, then per two bits represent the position of frame of video after out of orderization processing of the front relevant position of out of orderization processing, if the position of frame of video after out of orderization processing of the front relevant position of 00 expression out of orderization processing is the 1st frame, the position of frame of video after out of orderization processing of the front relevant position of 01 expression out of orderization processing is the 2nd frame, the position of frame of video after out of orderization processing of the front relevant position of 10 expression out of orderization processing is the 3rd frame, the position of frame of video after out of orderization processing of the front relevant position of 11 expression out of orderization processing is the 4th frame, and frame sequential information corresponding to this frame of video group is so:
Table 5:
1 0 0 1 1 1 0 0
Step 33 according to cryptographic algorithm and the encryption key consulted in advance with described terminal equipment, is encrypted the frame sequential information that obtains, and generates video certificate corresponding to described the first stream of video frames.
If video server adopts above-mentioned out of orderization of the first processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, then video server is directly according to cryptographic algorithm and the encryption key consulted in advance with terminal equipment, the frame sequential information that obtains is encrypted, generates video certificate corresponding to the first stream of video frames;
If video server adopts above-mentioned out of orderization of the second processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, and terminal equipment only has the authority of the partial video frame stream (the second stream of video frames) of playing in the first stream of video frames, then video server is at first determined the positional information in first stream of video frames of the second stream of video frames before out of orderization processing, and according to cryptographic algorithm and the encryption key consulted in advance with described terminal equipment, the frame sequential information that obtains and the positional information of determining are encrypted, generate video certificate corresponding to described the first stream of video frames.
Wherein, video server determine in first stream of video frames of the second stream of video frames before out of orderization processing positional information can but be not limited to realize by following dual mode:
The first is determined mode, video server is with number and the start frame of described the second stream of video frames and the frame position information in first stream of video frames of end frame before out of orderization processing of the frame of video that comprises in each frame of video group, be defined as the positional information in first stream of video frames of described the second stream of video frames before out of orderization processing, for example, the number of the frame of video that comprises in each frame of video group is 4, the position of the start frame of the second stream of video frames in the first stream of video frames is the 400th frame, and the position of the end frame of the second stream of video frames in the first stream of video frames is the 50000th frame;
The second is determined mode, video server is with the number of the frame of video that comprises in each frame of video group, time started dot information and concluding time dot information in first stream of video frames of described the second stream of video frames before out of orderization processing, and the frame rate information of described the first stream of video frames, be defined as the positional information in first stream of video frames of described the second stream of video frames before out of orderization processing, for example, the number of the frame of video that comprises in each frame of video group is 4, the time started point of the second stream of video frames is the 5th second, the concluding time point of the second stream of video frames is the 10th second, and frame rate was 25 frame/seconds.
In the embodiment of the invention two, after generating video certificate corresponding to described the first stream of video frames, the described video certificate of the first stream of video frames after the out of orderization processing and generation can be transferred to described terminal equipment, if video server adopts above-mentioned out of orderization of the first processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, then video server directly is transferred to terminal equipment with the first stream of video frames after the out of orderization processing; If video server adopts above-mentioned out of orderization of the second processing mode that each frame of video in the first stream of video frames is carried out out of orderization processing, then video server according to the frame of video group in the first stream of video frames by the order after arriving first, successively each the frame of video group after the out of orderization processing is transferred to terminal equipment.Wherein, first stream of video frames and the video certificate of generation when being transferred to terminal equipment of video server after with out of orderization processing, can transmit first the first stream of video frames after the out of orderization processing, transmit again the video certificate that generates, also can transmit first the video certificate of generation, transmit again the first stream of video frames after the out of orderization processing, can also be simultaneously the video certificate of the first stream of video frames after the out of orderization processing and generation be transferred to terminal equipment, the embodiment of the invention two does not specifically limit the sequencing that transmits the first stream of video frames and video certificate.
