Methods and apparatus to monitor audio/visual content from various sources
First Claim
1. A method to monitor media content provided by a selected one of a plurality of media content sources for presentation by an information presenting device, the method comprising:
- determining first information based on a video signal corresponding to the monitored media content;
determining second information based on an audio signal corresponding to the monitored media content;
determining third information based on a remote control signal;
identifying the selected one of the plurality of media content sources based on a first classification decision resulting from the first information and the second information, a second classification decision resulting from the second information, and evaluation of the third information; and
identifying the monitored media content based on identification information associated with at least one of the video signal or the audio signal.

9. A method to monitor media content provided by a selected one of a plurality of media content sources for presentation by an information presenting device, the method comprising:
-
determining first information based on a video signal corresponding to the monitored media content; determining second information based on an audio signal corresponding to the monitored media content; identifying the selected one of the plurality of media content sources based on a first classification decision resulting from one of the first information and the second information and a second classification decision resulting from the other of the first information and the second information, wherein identifying the selected one of the plurality of media content sources comprises deciding whether the selected one of the plurality of media content sources is at least one of a live digital television broadcast, a time-shifted digital television presentation or a DVD presentation based on whether the first information comprises a macroblock measurement and whether the second information comprises an audio compression measurement, and wherein deciding whether the selected one of the plurality of media content sources is the at least one of the live digital television broadcast, the time-shifted digital television presentation or the DVD presentation comprises deciding that the selected one of the plurality of media content sources is at least one of the live digital television broadcast or the time-shifted digital television if the first information comprises the macroblock measurement and the second information comprises the audio compression measurement, wherein the macroblock measurement is representative of a media content presentation exhibiting substantially no macroblocking and the audio compression measurement is representative of AC3 compression; and identifying the monitored media content based on identification information associated with at least one of the video signal or the audio signal. - View Dependent Claims (10)

12. A multi-engine meter to monitor media content provided by a selected one of a plurality of media content sources for presentation by an information presenting device, the multi-engine meter comprising:
-
at least one audio engine to process audio samples corresponding to the monitored media content; at least one video engine to process video samples corresponding to the monitored media content; at least one metadata engine to process at least one of the audio samples or the video samples; and a decision processor to evaluate a decision tree comprising at least two decision nodes to identify the selected one of the plurality of media content sources, each decision node of the decision tree corresponding to a decision metric evaluated using information generated by at least one of the at least one audio engine, the at least one video engine or the at least one metadata engine, a second decision node of the decision tree being selected for evaluation based on an outcome of evaluating a preceding first decision node of the decision tree. - View Dependent Claims (13, 14, 15)
