Abstract
DVD reproducing apparatus which transmits variable-bit rate data on a digital serial bus having a predetermined transmission rate. The DVD reproducing apparatus reproduces data from a record medium in accordance with a control signal to produce variable rate data. The data rate of the variable rate data is detected at predetermined intervals of time, a rate of transmission of the variable rate data is established in accordance with the detected data rate, and the variable rate data is transmitted in accordance with the established transmission rate. The DVD reproducing apparatus includes an MPEG decoder which MPEG decodes the reproduced data and which generates the control signal in accordance with amounts of data stored within various buffers, such control signal being utilized to control the reproduction of the data from the record medium. A receiver, e.g., a digital television, having an MPEG decoder therein receives the transmitted data and MPEG decodes the data, but such MPEG decoder does not generate a control signal similar to the previously generated control signal in order to prevent underflow/overflow of the memories therein. In another embodiment, the DVD reproducing app…
