Sistema de processamento de um sinal de televisão incluindo um componente de vídeo e um componente relacionado de áudio

摘要

A system for processing audio and video components of a television signal provides for automatic control of closed caption signal display in response to the status (220) of an audio muting feature. The system includes an operating mode in which enabling audio muting (MUTE ON) also enables the closed caption display (250) and disabling muting (MUTE OFF) disables generation of the closed caption display (280).
