ADVB sending control circuit and implementation method

The invention relates to an ADVB sending control circuit and an implementation method. The ADVB sending control circuit comprises a sending control unit, a receiving line buffer area, a receiving line buffer management register, a current line number register, an image data label register, a video image configuration unit and a CRC calculation unit. The sending control unit is used for reading and maintaining line image data in the receiving line buffer area, performing framing processing, data judging, container organizing and ADVB framing work on the line image data and establishing a sent data error processing mechanism. According to the ADVB sending control circuit and the implementation method, framing, packaging and processing of video image data can be achieved through hardware, and the sending delay minimality of the video image data can be guaranteed; receiving and processing of video images with different formats can be self-adapted; the error data processing mechanism is supplied, and therefore the validity and the continuity of an ADVB data frame of a submitted link can be guaranteed.
