Abstract:
1. A transmission method in which data having a predetermined data length as a unit is transmitted between devices for transmitting data through an IEEE 1394 bus by a predetermined format, said transmission method comprising the steps of: locating label data indicating that said transmission data is data resulting from compressing digital audio data at a starting portion of said data having the predetermined data length as a unit; locating sub-label data indicating the compression system, at an interval following its label data; and locating audio stream data compressed by the compression system indicated by said sub-label data at an interval following said sub-label data and transmitting resultant data, said predetermined format is a format complying with a protocol for transmitting data in an isochronous transfer mode through said IEEE 1394 bus, and a plurality of said data having said data length as a unit are located at an interval following a header prescribed by said protocol, and one of a label and sub-label indicating that the data is ancillary data is located at data of a part of a unit of said plurality of data having said predetermined data length, and data accompanying said audio stream data is located at an interval behind said one of said label or sub-label indicating that the data is ancillary data.
