Audio Modifications in Digital Media Decoders
First Claim
1. A decoder module for decoding a received signal in a digital media system, the received signal comprising a video component, an audio component, and program content information classifying a current program into one of a plurality of predefined program content categories, the decoder module comprising:
- an audio decoder for decoding the audio component of the received signal and outputting a decoded audio signal;
a memory comprising a plurality of audio modification data sets, each of the plurality of audio modification data sets comprising information utilized to modify audio characteristics; and
an audio processor connected to the audio decoder for receiving the decoded audio signal and obtaining one of the plurality of audio modification data sets selected according to the program content information of the received signal;
wherein the audio processor modifies the decoded audio signal according to the selected audio modification set and outputs the modified decoded audio signal.

Abstract
A demodulated signal in a digital media system includes an audio bitstream that is transmitted to an audio decoder and program information that includes program content category. A plurality of customizable sets of data that identify desired modifications to audio characteristics are respectively associated with specific program content categories. Program content category information is obtained from the received program information and the audio modification data set associated with that program content category is applied to the decoded audio signal before output.
