Disclosed is a data stream processor that allows both the coder side and the decoder side to obtain reference time information needed to generate a reference frequency from the same external reference time station, and uses the same frequency for encoding and decoding. The invention is particularly useful when a plurality of data streams data are received and decoded. A decoder side performs decoding at the same frequency as a reference frequency for each coder side that generated the stream data, because if the same frequency is not used for encoding, stream data will be lost or insufficient in a decoder's buffer for storing stream data. This causes errors such as repeating audiovisual data, missing frames, etc. When the reference time needed for the decoder side to adjust frequencies is embedded in each stream data, it is difficult to adjust frequencies for all the stream data.
