Abstract:
1. A data transmission method of transmitting a serial digital transfer interface transmission packet in which an interval of one line of a video frame comprises an end synchronizing code area in which an end synchronizing code is inserted, an ancillary data area into which ancillary data is inserted, a start synchronizing code area into which a start synchronizing code is inserted, and a payload area into which data containing a video signal is inserted, said data transmission method comprising the steps of: a first step of inserting data indicative of a transfer mode of said transmission packet into said payload area; and a second step of transferring said transmission packet into which the data indicative of said transfer mode was inserted at said first step in the form of serial data, whereby the position within said payload area where said data indicative of said transfer mode is inserted is based on both said transfer mode and a timing mode of said transmission packet, and wherein said video signal is data compressed according to the MPEG standard.
