Abstract
A signal coding apparatus, which is coupled, via a transmission path, to a receiver having a receiver buffer and a decoder, includes a coding unit for coding a signal and outputting information generated in a frame unit, the information being a coded signal. The apparatus also includes a transmitter buffer for temporarily storing the information, and a controller for controlling an amount of the information on the basis of a storage capacity of the receiver buffer and an amount of the information which is contained in a frame per a unit time. There is also provided a method used in the above coding apparatus, and a signal coding transmission system employing the signal coding apparatus.
