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.
