Abstract
In a video signal recording apparatus, a first video signal is compressed into a second video signal in response to a controllable quantization factor which determines a degree of the compression. The quantization factor is controlled to maintain a data rate of the second video signal at substantially a constant rate. A detection is made as to a magnitude of the quantization factor. A decision is made as to whether or not the detected magnitude is greater than a predetermined reference magnitude. The second video signal is recorded on a recording medium when the detected magnitude is greater than the predetermined reference magnitude.
