To provide a stream transmission reception system, that transmits a multiplexed stream assembled into packets or cells via a digital transmission network and realizes a receiver for correcting fluctuations in a time reference value due, to delay fluctuations and supplying the corrected stream to a decoder, using a small device scale.
A transmitter 2 is provided with an attached information superimposing section 202, in addition to a multiplexed stream transmission section 201, and the receiver 4 is provided with a time reference value correction section 402, in addition to a multiplexed stream reception section 401. The transmitter 2 and the receiver 4 receive a common clock to drive a timer, the transmitter 2 transmits the time reference value, included in a multiplexed stream with the time of the timer attached thereto, as attachment information to the receiver 4, and the receiver 4 rewrites the time reference value, on the basis of a difference between the time denoted by the attached information and a time of its own timer, so as to eliminate fluctuations in the time reference which is included in the multiplexed stream to a decoder 5.
