Abstract
The invention discloses a digital television live program broadcasting integrity judging method. The method comprises the following steps of respectively extracting the characteristic value of each frame image from a compressed video at a digital television transmission terminal and a broadcasting platform output terminal; transmitting the characteristic value of each frame image, which is extracted from the digital television transmission terminal to a broadcasting platform; comparing the characteristic value of each frame image, which is extracted from the digital television transmission terminal, with the characteristic value of a corresponding image, which is extracted from the broadcasting platform output terminal; and judging whether a program is completely broadcast or not according to the comparison result. Compared with the traditional image decoding comparison method, the method is technologically advantaged in that 1) a decoder is not required, so that the cost is saved, 2) the decoded image is not required to be transmitted back (or the video compression data at the transmission terminal is not required), so that the network bandwidth is saved, and 3) the accuracy of judgment is improved compared with the method of decoding the image and transmitting the image back.
Description
Technical field
The present invention relates to digital TV field, refer to that especially a kind of digital TV direct program broadcasts the integrality determination methods.
Background technology
Radio and television are watched from the user that the Broadcast Control platform broadcasts end, can pass through many links, are maliciously tampered in transmission for preventing content of TV program, and the broadcast integrality of programme televised live video is checked it is necessary.
Video coding generally adopts MPEG-2 or compressed format H.264/AVC in the digital television program.The programme televised live integrality judges that promptly to the programme televised live of same channel, the video content of comparative figures television transmission terminal (hereinafter to be referred as the A point) and broadcast platform (hereinafter to be referred as the B point) judges whether the two is consistent.Because video is made up of the continuous images frame, the method that extensively adopts at present has two kinds: 1. respectively the video of program is decoded at A point and B point, decoded every frame video image is transferred to the B point compares judgement.The determination methods defective of decoding passback picture frame is: 1) need decoder, cost is higher; 2) pass back to the B point to the decoded picture frame of A point, need take the bigger network bandwidth; 3) because the back picture frame of decoding is compared, accuracy rate relatively is lower, can't truly reflect the integrality of programme televised live.2 packed datas that digital television transfer is terminal directly pass back to the broadcast platform and compare.Though the accuracy rate of this method comparison can meet the demands, the packed data that digital television transfer is terminal passes back to the broadcast platform need take the bigger network bandwidth equally.
Summary of the invention
To the problem that prior art exists, the object of the present invention is to provide the digital TV direct program that a kind of cost is low, the saving net omits bandwidth, judging nicety rate is high to broadcast the integrality determination methods.
For realizing above-mentioned purpose; Digital TV direct program of the present invention broadcasts the integrality determination methods; Be specially: broadcast the platform output extracts every two field picture respectively from the video of compression characteristic value at digital television transfer end and DTV; Characteristic value with the terminal every two field picture that extracts of digital television transfer is sent to DTV broadcast platform then; And compare with characteristic value that DTV broadcasts the correspondence image that the platform output extracts, judge according to comparative result whether the program video broadcast is complete.
Further, said characteristic value comprises PTS, frame bandwidth and crc value; Wherein, PTS representes the demonstration temporal information of every two field picture; The frame bandwidth is represented every frame image data size; Crc value representes that every frame image data uses the result after CRC is calculated.
Further; Digital television transfer is terminal when comparing with the characteristic value of broadcasting the correspondence image that the platform output extracts, with said PTS as benchmark relatively, if the identical characteristic value that is regarded as identical image of PTS; And then more said frame bandwidth and crc value; If the frame bandwidth is also identical with crc value, it is complete then to be regarded as this two field picture broadcast, otherwise is regarded as broadcasting imperfect; Repeat above-mentioned steps all two field pictures in the video are judged, judge finally whether complete program video is broadcasted.
The present invention is than the traditional image comparative approach of decoding, and the technological progress of this method is:
1) do not need decoder, provide cost savings.
2) need not return decoded image (or the terminal video compression data of transmission), save the network bandwidth.
3), improved the accuracy rate of judging than the decoding passback.
Description of drawings
Fig. 1 is the flow chart of the inventive method;
Fig. 2 is the flow chart of manner of comparison in the inventive method.
Embodiment
As shown in Figure 1, digital TV direct program of the present invention broadcasts the integrality determination methods, is specially: for the TV programme of same channel, the workflow terminal in digital television transfer comprises: the PTS 101 ' that extracts every two field picture; Add up the frame bandwidth 102 ' of every two field picture; Calculate the crc value 103 ' of every frame image data; Above-mentioned three characteristic values are passed back to broadcast platform 105.Similar, the workflow of broadcasting platform in numeral comprises: the PTS 101 that extracts every two field picture; Add up the frame bandwidth 102 of every frame; Calculate the crc value 103 of every frame image data; Three characteristic values to sending from the digital television transfer end and DTV broadcast three characteristic values that platform extracts and compare and judge whether the video broadcast is complete.
Judge that DTV broadcasts the judgment principle of platform and the terminal program integrity of broadcasting of digital television transfer, as shown in Figure 2.When the terminal characteristic value with the correspondence image of broadcasting the extraction of platform output of digital television transfer compares; With the benchmark of said PTS as comparison; If the PTS difference would think digital television transfer terminal with broadcast the different images that is that the platform output broadcasts, it is imperfect to judge that image broadcasts; If the identical characteristic value that is regarded as identical image of PTS, and then more said frame bandwidth and crc value, if the frame bandwidth is also identical with crc value, it is complete then to be regarded as this two field picture broadcast, broadcasts imperfect otherwise be regarded as image; Repeat above-mentioned steps all two field pictures in the video are judged, judge finally whether complete program video is broadcasted.
Above-mentioned example is used to just explain that the present invention, the present invention are not limited to these examples, and the various embodiments that meet inventive concept that those skilled in the art made are all within protection scope of the present invention.
