Abstract
This invention relates to a data transmission method or the like for use in transmitting video data, audio data or the like. There is transmitted a serial digital transfer interface transmission packet in which an interval of each line of a video frame comprises an end synchronizing code area into 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 the payload area, there are inserted first data containing extension data having stream information and second data containing main data comprising video data and/or audio data at the picture unit of video data. The stream information is information which indicates whether or not the picture unit belongs to a pre-roll interval located ahead of an editing interval, whether or not the picture unit belongs to an editing interval and whether or not the picture unit belongs to a post-roll interval located behind an editing interval. A reception side becomes able to positively edit data on a VTR, for example, by effectively utilizing the stream information.
