Variable encoding and detection apparatus and methods
View Patent ↗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.
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.
2. A method as defined in claim 1 , wherein the media source type is a television source, a radio source, or a computer source.
3. A method as defined in claim 1 , wherein the media source type is at least one of an over-the-air broadcast signal, a cable broadcast signal, a satellite broadcast signal, an analog signal, or a digital signal.
4. A method as defined in claim 1 , wherein the broadcast station code is at least one of a television station code or a radio station code.
5. 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 relatively high power level code or a relatively low power level code; and
encoding, with the processor, the media signal with a code using the selected encoding 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.
7. 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; and
encoding, with the processor, the media signal with the code by generating the code to have a predetermined frequency spectrum.
8. An apparatus for encoding a media signal, comprising:
a processor coupled to a memory, wherein the processor is programmed to;
determine a media source type associated with a media signal by extracting a broadcast station code from the media signal;
select an encoding mode that uses a code having a power level that is based on the media source type; and
encode the media signal with a code using the selected encoding mode.
9. An apparatus as defined in claim 8 , wherein the media source type is a television source, a radio source, or a computer source.
10. An apparatus as defined in claim 8 , wherein the media source type is at least one of an over-the-air broadcast signal, a cable broadcast signal, a satellite broadcast signal, an analog signal, or a digital signal.
11. An apparatus as defined in claim 8 , wherein the broadcast station code is at least one of a television station code or a radio station code.
12. An apparatus for encoding a media signal, comprising:
a processor coupled to a memory, wherein the processor is programmed to;
determine a media source type associated with a media signal;
select 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 relatively high power level code or a relatively low power level code: and
encode the media signal with a code using the selected encoding mode.
13. An apparatus for encoding a media signal, comprising:
a processor coupled to a memory, wherein the processor is programmed to;
determine a media source type associated with a media signal;
select 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
encode the media signal with a code using the selected encoding mode.
14. An apparatus for encoding a media signal, comprising:
a processor coupled to a memory, wherein the processor is programmed to;
determine a media source type associated with a media signal;
select an encoding mode that uses a code having a power level that is based on the media source type; and
encode the media signal with a code using the selected encoding mode by generating the code to have a predetermined frequency spectrum.
