Picture frame memory module 24 is used for the incidence relation of the key frame of the Word message of programs stored and extraction, the key frame of extraction;
Picture frame contrast module 22, the program number of the literal programme that is used for verification that sends according to programme module 20, obtain the Word message of this program and the incidence relation of key frame according to this program number from picture frame memory module 24, and from picture frame memory module 24, obtain the key frame of this program according to described incidence relation, and with buffer 26 in the verification frame contrast of this program, comparing result is sent to playing control unit 16;
This system connects literal programme memory module 12 and video server unit 18, literal programme memory module 12 connects literal programme editor module 10, be used to store literal programme editor module 10 editors' literal programme, so-called literal programme only contains the text message of program; Video server unit 18 is used for programs stored and pad; Provide broadcast program and pad to playing control unit 16; So-called pad is meant through the legal program of examination, separates in video server unit 18 with program and deposits.
The Play Control strategy comprises to be play pad, or plays next program, or change artificial treatment over to when the verification frame of key frame in the picture frame memory module 24 and extraction is inconsistent; Perhaps, during current playing programs, according to the literal programme, to the subsequent program verification successively of current program; For pad, according to user's request, also can extract key frame, the verification frame carries out verification.
In the above system, broadcast program more also can not established buffer 26, and picture frame abstraction module 14 directly sends to picture frame contrast module 22 with the verification frame that extracts, and picture frame contrast module 22 is obtained this verification frame, contrasts with key frame.
In addition, the programme memory module connects user terminal by network, is used for providing the literal programme to user terminal; Picture frame memory module 24 connects user terminal by network, and being used for provides the incidence relation of the key frame of the Word message of program and extraction, the key frame of extraction to user terminal.Like this, user terminal can be visited literal programme memory module 12 and picture frame memory module 24 by network, obtain the literal programme from literal programme memory module 12, obtain the incidence relation of the key frame of the Word message of respective program and extraction, the key frame of extraction from picture frame memory module 24, like this, user terminal is seen the programme that has picture frame, can get more information about the content of broadcast program.
With program number is 100001, and title is: Olympic Five Ring, duration be from the 00:00:00:00 frame, and 00:00:29:24 finishes, and promptly 30 seconds program is an example, adopts above system, the program broadcasting method flow process as shown in Figure 3, this method comprises:
According to the demand of programming, literal programme editor module 10 obtains the Word message of program from video server unit 18, the literal programme of editing program, the programme of this article word only has content of text, and do not have the image information of respective program, the literal programme that edits is stored in literal programme memory module 12.
Step 201, programme module 20 send to picture frame abstraction module 14 and extract the key frame order, and picture frame abstraction module 14 receives this order;
Program is non-linear storage in video server unit 18, so-called non-linear storage is meant: because the storage of each picture frame of program and the time order and function sequence independence of each picture frame, but adopt program number as sign, the mode that the side-play amount of first frame address of recorded program and the first relatively frame of each picture frame combines is stored, the side-play amount of program number, the first frame address of program and picture frame is stored in the concordance list, just can directly finds each picture frame of required programs according to concordance list.In addition, the compression coding mode of each program self is different, and under the different compression coding modes, the data format of each picture frame is different.In program data, put down in writing the coding characteristic of this program, extracted the coding characteristic of putting down in writing in this program, and, adopted corresponding mode to find the key frame of this program according to different coding characteristics.So-called key frame, the first frame of dactylus purpose, designated frame and tail frame here, designated frame is specified according to user's request.
Step 202, picture frame abstraction module 14 extract the key frame of respective program from video server unit 18, and send to programme module 20;
At above-mentioned example, when extracting the key frame of program,, in video server unit 18, find this program at first according to the program number in the programme 100001; Then, extract program 100001 coding characteristics, determine the data format of program 100001 according to 100001 coding characteristic, seek first frame 00:00:00:00 frame, designated frame 00:00:10:00 frame and the tail frame 00:00:29:24 frame of program 10001, extract index information, address information, the vedio data of key frame.
Step 203, programme module 20 are related with the key frame of this program of extraction with the Word message of this program, store the Word message of program and incidence relation, the key frame of key frame into picture frame memory module 24.
Before step 3, the playing programs, obtain the Word message of this program and the incidence relation of key frame, obtain the key frame of this program according to described incidence relation according to the program number in the literal programme; And extract the verification frame of this program, with the key frame of this program of preserving relatively, if consistent, normal play then, otherwise, play pad.Detailed process is as follows:
Before step 301, the playing programs, programme module 20 sends check command to picture frame abstraction module 14, sends the program number that is used for verification to picture frame contrast module 22;
In the above-mentioned example, before broadcast, programme module 20 sends to picture frame contrast module 22, command diagram picture frame abstraction module 14 verification programs 100001 with program number 100001.
Step 302, picture frame abstraction module 14 extract the verification frame of video server unit 18 respective program, and send to buffer 26 according to the check command that programme module 20 sends;
So-called verification frame is exactly the key frame that arrives the program that extracts video server unit 18 again, and the extraction mode is identical with the extraction of key frame.Picture frame abstraction module 14 extracts the verification frame of program 100001 from video server unit 18, first frame 00:00:00:00 frame, designated frame 00:00:10:00 frame and tail frame 00:00:29:24 frame, and the extraction mode is identical with step 2, and sends to buffer 26.
Step 303, picture frame contrast module 22 send the program number of the literal programme that is used for verification according to programme module 20, from picture frame memory module 24, obtain the Word message of respective program and the incidence relation of key frame, obtain the key frame of this program according to described incidence relation, and with the contrast of the verification frame of this program that from buffer 26, obtains, comparing result is sent to playing control unit 16;
Picture frame contrast module 22 is obtained the Word message of program 100001 and the incidence relation of key frame according to the program number in the literal programme 100001 from picture frame memory module 24.So-called incidence relation is exactly in the picture frame memory module 24, the memory address of the key frame of the program 100001 corresponding with the Word message of program 100001.Key frame memory address according to program 100001, obtain the key frame that extracts before the program 100001, with 100001 the verification frame contrast of obtaining from buffer 26, whether with the image information of tail frame 00:00:29:24 frame consistent, and comparing result is sent to playing control unit 16 if promptly contrasting 10001 key frame, the first frame 00:00:00:00 frame in the verification frame, designated frame 00:00:10:00 frame.
If step 304 verification frame is consistent with key frame, playing control unit 16 normal play programs then, otherwise, play pad.
So-called pad is meant through the legal program of examination, and with video server unit 18 in other programs separate and deposit, it has been generally acknowledged that pad is that safety is legal.
In the step 302,303, if do not establish buffer 26 in the system, then the picture frame extracting unit directly sends to picture frame contrast module 22 with the verification frame that extracts and compares and get final product.
In the step 304, if inconsistent in the picture frame of the program of Chou Quing and the programme again, can also skip this program, play next program, certainly next program is also needed safety check, because method of the present invention only extracts three picture frames of program, the time spent is very short, so can not influence playing programs; Can also transfer hand inspection to, confirm by the staff whether this program is legal, and then determine to play this program or play pad, perhaps skip this program, play next program.For pad, if worried its fail safe, also can be the same with program, adopt method of the present invention to carry out safety check, and pad also can have a plurality of, can better guarantee the safety of playing programs like this.
In the step 3, not only before playing programs,, can obtain the Word message of this program and the incidence relation of key frame according to the program number in the literal programme at any time, obtain the key frame of this program according to described incidence relation if the user needs; And extract the verification frame of this program, with the key frame of this program of preserving relatively, if consistent, then keep this program, otherwise delete this program or change this program.In addition, after the step 3, if a program is play, according to the order in the literal programme, subsequent program to current program is carried out verification successively, that is: obtain the Word message of this program and the incidence relation of key frame according to the program number in the literal programme, obtain the key frame of this program according to described incidence relation; And extract the verification frame of this program, with the key frame of this program of preserving relatively, according to comparative result, keep or deletion or change this program.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
