Abstract
This invention relates to a data transmission method or the like suitable for 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. The payload area has inserted thereto first data containing extension data having editing point information at the picture unit of video data and second data containing main data comprising video data and/or audio data. The reception side is able to effect a necessary processing such as muting of sounds on the editing point by effectively utilizing editing point information.
