Video signal encoding and recording apparatus with variable transmission rate |
摘要 |
In a video signal encoding and recording apparatus, a video signal is quantized into a quantization-resultant signal in response to a variable quantization scale. The quantization-resultant signal is recorded on a recording medium. The quantization scale is controlled in response to an encoding rate. The quantization scale is limited to within a range determined by a limit quantization scale. A remaining record capacity of the recording medium is measured. A remaining record time is measured. The encoding rate and the limit quantization scale are updated in response to the measured remaining record capacity and the measured remaining record time.
