Abstract
DVD reproducing apparatus which transmits variable-bit rate data on a digital serial bus having a predetermined transmission rate. The apparatus employs a reproducing device to reproduce data from a record medium in accordance with a control signal to produce variable rate data. The control signal is generated on the basis of at least two buffer storage state indicators corresponding to respective data buffers, one of which is incorporated into the reproducing device. The peak data rate of the variable rate data is detected, a rate of transmission of the variable rate data is established in accordance with the detected peak data rate, and the variable rate data is transmitted in accordance with the established transmission rate.
