Abstract

See full text

A received transport stream may be demultiplexed into a compressed audio stream and a control stream. The compressed audio stream may be decoded. Audio corresponding to a tuned program may be stored. The stored audio may be separated from the compressed audio stream by subtracting the stored audio from the decoded audio stream, until a no-active-speech command is found in the control stream. Responsive to the no-active-speech command, the subtracting may be omitted for a period corresponding to a duration of the no-active-speech command.
