Communication system in audio and music data transmission
A transmission method and apparatus for detecting the format of data when data is absent from the transmission packets. In situations where data to be transmitted via a predetermined network (e.g., IEEE 1394) is absent (i.e., missing, incomplete, intentionally blank, or not ready to be transmitted), the transmission method allows for the format of the absent data to be determined by the receiving side. According to this transmission method, the data transmission packets include a label section that indicates the format of the data or the absence of data. When the label section indicates an absence of data, a label group section is included in the data transmission packet to indicate the format of the data which is absent. This allows the receiving side to determine the format of the data that it should be receiving.
