Abstract
Methods and apparatus to distinguish a signal originating from a local device from a broadcast signal are disclosed. A disclosed example method includes analyzing a first predetermined characteristic of a video component of the audio-video signal to generate a first indication of the source of the audio-video signal, analyzing a second predetermined characteristic of an audio component of the audio-video signal to generate a second indication of the source of the audio-video signal, and determining if the audio-video signal was generated by a local device based on the first and second indications.
Claims19
A method of identifying a source of an audio-video signal, the method comprising:
- comparing a first characteristic of a first frame of a video component of the audio-video signal to a second characteristic of a second frame of the video component to generate a first indication of the source of the audio-video signal, the first frame having been received from an output of a media device and the second frame having been received from the same output of the media device;
- analyzing a second characteristic of an audio component of the audio-video signal to generate a second indication of the source of the audio-video signal;
- and
- distinguishing, with a processor, audio-video signals generated from a local tangible medium from signals transmitted by a content provider based on the first and second indications.
An apparatus to classify an audio-video signal, the apparatus comprising:
- a memory;
- and
- video/audio classifier to identify that an audio-video signal is either a locally generated signal or a broadcast signal by:
- comparing a first characteristic of a first frame of a video component of the audio-video signal to a second characteristic of a second frame of the video component to generate a first indication of the source of the audio-video signal, the first frame having been received from an output of a media device and the second frame having been received from the same output of the media device;
- analyzing a second characteristic of an audio component of the audio-video signal to generate a second indication of the source of the audio-video signal;
- and
- distinguishing audio-video signals generated from a local storage device from signals transmitted by a content provider based on the first and second indications.
A tangible storage device or disk comprising instructions that, when executed, cause a machine to identify a source of an audio-video signal by at least:
- comparing a first characteristic of a first frame of a video component of the audio-video signal to a second characteristic of a second frame of the video component to generate a first indication of the source of the audio-video signal, the first frame having been received from an output of a media device and the second frame having been received from the same output of the media device;
- analyzing a second characteristic of an audio component of the audio-video signal to generate a second indication of the source of the audio-video signal;
- and
- distinguishing audio-video signals generated from a local tangible medium from signals transmitted by a content provider based on the first and second indications.
