PROBLEM TO BE SOLVED: To transmit data of variable rate through the use of the transmission line of a predetermined rate. SOLUTION: A digital signal fetched from the reproducing means 1 of DVD, e.g. is supplied to an error correcting and memory controlling circuit 4 and an RAM 5, and the error-corrected digital signal is supplied to an MPEG decoder 6, e.g. In addition, the control circuit 301 of IEEE-P1394, for example, is provided to supply the digital signal through a bit rate detecting block 8. The block 8 detects (calculates) a bit rate, the number of units necessary for transmission is calculated from the value this bit rate, and the control circuit 301 secures a transmission band so as to transmit the number of these units. Thereby the digital signal is transmitted to a digital television receiver 200 with an MPEG decoder 9, e.g. through a digital serial bus 300. |
