1. A method of encoding a media signal, comprising:
- determining, with a processor, a media source type associated with a media signal by extracting a broadcast station code from the media signal;
selecting, with the processor, an encoding mode that uses a code having a power level that is based on the media source type; and
encoding, with the processor, the media signal with a code using the selected encoding mode.

Abstract
Apparatus, methods, and articles of manufacture for media monitoring are disclosed. In particular, the example apparatus, methods, and articles of manufacture determine a media source type associated with a media signal and select an encoding or decoding mode based on the media source type. An encoding operation encodes the media signal using the selected encoding mode and a decoding operation decodes the media signal using the selected decoding mode.

6. A method of encoding a media signal, comprising:
-
determining, with a processor, a media source type associated with a media signal; selecting, with the processor, an encoding mode that uses a code having a power level that is based on the media source type by selecting an encoding mode that uses a code having a first power level or a second power level greater than the first power level; and encoding, with the processor, the media signal with a code using the selected encoding mode.
