PURPOSE: To easily judge which kind of data does not exist at a reception side by arranging label data which indicates that data does not exist in a first section in a prescribed data length, arranging data indicating the kind of non- existence data in the second section and transmitting them. CONSTITUTION: Unless data to be transmitted exists in a transmission processing part, the value of data (EXT-No-data) indicating that data does not exist among data is arranged in the eight-bit section where head label (LABEL) data are arranged with the 32 bits prepared for transmitting audio data as one unit. Then data of a label group (LABEL-Gp.) are arranged in the succeeding eight-bit section after the section. It is indicated which kind of data is in a non-existence state in data of the label group. Data created at random are arranged in the remaining 16-bit section in 32-bit data. |
