摘要 |
A system for automatically adapting the mean sound level of a television receiver. The system for automatically adapting the mean sound level of a television receiver comprises an adapting module comprising both a video adapting circuit comprising at least one additional input highpass filter and a fixedgain video amplifier connected in series and interposed in the video image processing circuits at means for providing video image signals, and secondly an audio adapting circuit interposed in the sound path at means for taking audio signals to detect the input mean level of sound, to compare said mean level of sound with a pre-established reference mean level, and automatically to adapt the mean level of output sound to maintain it at the pre-established reference mean level.
