Abstract
A video signal encoding apparatus performs the quantization based on a predetermined quantizer scale, so the picture quality of an encoded video signal can be maintained. The video signal encoding apparatus sequentially stores an input video frame signals and converts a stored video frame signal from the spatial domain into the frequency domain to provide transform data and quantizes the transform data based on a predetermined quantizer scale to provide quantized transform data. The video signal encoding apparatus statistically codes the quantized transform data to produce an encoded video frame signal and temporarily stores the encoded video frame signal in order to transmit the encoded video frame signal at a constant transmission rate and provides a control signal to thereby enable a video frame signal, being stored at the moment when the transmission of the encoded video frame signal is completed, to be transformed.
