Detection and Handling (EDH), can optionally be placed in the vertical interval of the video signal for integrity checking. Error Detection and Handling (EDH) is a signal for error detection in digital video that is transmitted in Ancillary Data Space (ANC), the adequate blanking interval in digital video. Error Detection and Handling is based on cyclic block check (CRC) as an error detection mechanism. In the CRC check, the EDH data is checked for one field at a time, and error handling takes effect if an error occurs. EDH is normally only used with the SD-SDI interface for SDTV.
