ABSTRACT:
A coding apparatus for coding a video signal by way of total data amount control. The video signal is coded by high efficient predictive coding to produce first encoded data. A data amount of the first encoded data is counted and converted to a target data amount within a reference data amount. In response to the target data amount, quantization is controlled in the high efficient predictive coding. The coding is again carried out to produce second encoded data under quantization control. The quantization is corrected in the high efficient predictive coding in response to the target data amount and a data amount of the second encoded data. The second encoded data is outputted at a specific data transfer rate.
