Abstract
In TV broadcasting environment, due to different settings in different TV stations, the sound level from each station may vary in a wide range. For general users, it may cause annoying experience since the TV sound level may change a lot when user switches the channel from one to the other. In addition, switching among TV reception and AV inputs may have similar problem. The present invention relates to a method and apparatus which can be easily integrated into a single IC to achieve a low cost TV sound level control solution.
