    Abstract: Digital video signature apparatus and methods for use with video program identification systems are disclosed. The example apparatus and methods generate a signature associated with a video program. An example system includes a frame scanner to scan video frames associated with the video program. The frame scanner is to select a video frame based on a number of intra-coded macro blocks within the video frame. The example system also includes an intra-coded macro block extractor to extract intra-coded macro blocks from the video frame and a scaled image extractor to extract a scaled image from the intra-coded macro blocks. A signature generator is also included in the example system to calculate a plurality of centroids associated with video frame based on the scaled image and to form the signature based on the plurality of centroids.

    Abstract: Methods and apparatus for characterizing media are described. In one example, a method of characterizing media includes capturing a block of audio; converting at least a portion of the block of audio into a frequency domain representation; dividing the frequency domain representation into a plurality of bands; determining a characteristic difference of a first band of the plurality of bands based on a comparison of a characteristic of the first band and a characteristic of a second band different from the first band, wherein the characteristic of the first band occurs at a time that is different than a time at which the characteristic of the second band takes place; and determining a signature bit based on a characteristic difference. Other examples are shown and described.

    Abstract: Methods and apparatus for determining whether a media presentation device is in an on state or an off state are disclosed. A disclosed example method comprises determining first and second characteristics of a signature associated with a signal representative of media content presented via a media presentation device, evaluating the first and second characteristics to determine first and second fuzzy contribution values representing, respectively, degrees with which the first and second characteristics correspond to the media presentation device being in at least one of an on state or an off state, determining a third fuzzy contribution value based on a number of the first and second contribution values indicating the media presentation device is in one of the on or off states, and combining the first, second and third fuzzy contribution values for use in determining whether the media presentation device is in the on state or the off state.
