Abstract
The characteristic of a digital video signal is detected by first characteristic detecting circuit, and the characteristic of a digital speech signal is detected by second characteristic circuit. Outputs of the first and second characteristic detecting circuit are synthesized by synthesizing circuit to control allocated information quantities of compression encoding of the digital video signal and the digital speech signal on the basis of an output of the synthesizing circuit, thereby making it possible to more efficiently compression-encode video signal and speech signal related thereto in the state of less degradation from a viewpoint of visual and auditory senses at the time of reproduction.
Claims12
An encoding apparatus adapted for respectively compression-encoding a digital video signal and a digital speech signal related thereto to transmit encoded signals, the apparatus comprising:
- first characteristic detecting means for detecting the characteristic of the digital video signal;
- second characteristic detecting means for detecting the characteristic of the digital speech signal;
- synthesizing means for synthesizing outputs of the first and second characteristic detecting means;
- and
- control means for controlling allocated information quantities of compression encoding of the digital video signal and the digital speech signal on the basis of an output of the synthesizing means.
An encoding method of respectively compression-encoding a digital video signal and a digital speech signal related thereto to transmit them,
- the method comprising the steps of:
- detecting the characteristic of the digital video signal;
- detecting the characteristic of the digital speech signal;
- synthesizing a characteristic detection output of the digital video signal and a characteristic detection output of the digital speech signal;
- and
- controlling allocated information quantities of compression encoding of the digital video signal and the digital speech signal on the basis of the synthesis output.
