ABSTRACT:
An apparatus for receiving and decoding a packet of a multiplexed bit stream whose data is coded in a predetermined format, includes a temporary storage memory for compensating for the difference between the timing of the received packet and the read-in timing of the coded data by a decoder, counters and a comparison circuit for producing a clock signal which serves as a reference for operating the decoder on the basis of a reference signal in the predetermined format, and a calculation circuit for calculating the position of the reference signal using a time which is periodically added to the packet.
