摘要:
The present invention is an in-train information display apparatus that displays, to a passenger, advertisement content delivered from an advertisement-content delivering apparatus, and includes a display unit configured to display the advertisement content, a display monitoring unit configured to photograph a video screen displayed on the display unit, and a display-result determining unit configured to calculate color-related information, which is information concerning a color of the video screen, based on an image photographed by the display monitoring unit, determine, based on the calculated color-related information and reference information for display result determination, which is information concerning a color of the advertisement content normally displayed on the display unit, whether the display of the advertisement content is normally performed, and transmit, as information for display achievement calculation, a result of the determination to the advertisement-content delivering apparatus having a totalizing function.

A method for matching a query against a broadcast stream includes receiving one or more broadcast streams, from which it generates and stores an audio fingerprint of a selected portion of each received broadcast stream. A query is received from which the method generates an audio fingerprint. From that point, the method continues by identifying audio content from the query, using the query audio fingerprint and a database of indexed audio content. The method concludes by identifying the source of the query using the query audio fingerprint and the stored audio fingerprints. Embodiments of the method further include predictively caching audio fingerprint sequences and corresponding audio item identifiers from a server after storing audio fingerprints extracted from the broadcast stream; and using the predictively cached audio fingerprint sequences to identify an audio item within the audio signal based on at least some additional audio fingerprints of the audio signal.

A method and system for monitoring a broadcast signal includes a transfer switch and a first receiver decoder circuit for a first channel coupled to the first transfer switch. The first receiver decoder circuit generates a first receiver decoder circuit signal. A second receiver decoder circuit for the first channel is coupled to the first transfer switch. The second receiver decoder circuit generates a second receiver decoder circuit signal. A monitoring display is formed in response to the first receiver decoder circuit signal and the second receiver decoder circuit signal for monitoring the broadcast signal.

A method for monitoring entertainment media (such as songs played on the radio) may include providing a plurality of conditions related to frequency of performances of particular recordings of entertainment media, receiving a selection of a subset of the conditions from a user, monitoring data of frequency of performances of the particular recordings of entertainment media, and transmitting an alert to the user when one or more conditions in the subset of conditions is met based on the data.

A system and method for tracking and managing playback of advertisements is disclosed. The system includes a processor configured to process the multimedia content, including advertisements, and generate a video signature/audio signature corresponding to the multimedia content. The video/audio signature is subsequently embedded/superimposed on at least one of the frames of the multimedia advertisement. The system further includes a plurality of trackers placed at predetermined geographic locations and configured to detect the broadcast television signal, and determine whether the video signature/audio signature is present in the broadcast signal. Subsequently, the tracker generates a report comprising at least a time stamp indicating the time of broadcast of the advertisement having the audio/video signature.

Example methods, apparatus and articles of manufacture to perform audio watermark decoding are disclosed. A disclosed example method includes receiving an audio signal including an audience measurement code embedded therein using a first plurality of frequency components, sampling the audio signal, transforming the sampled audio signal into a first frequency domain representation, determining whether the code is detectable in the first plurality of frequency components of the first frequency domain representation, and when the code is not detected in the first plurality of frequency components, examining a second plurality of frequency components of a second frequency domain representation to determine whether the code is detected, the second plurality of frequency components being offset from the first plurality of frequency components by a first offset, the first offset corresponding to a sampling frequency mismatch.

Media monitoring using multiple types of signatures is disclosed. Example media monitoring methods disclosed herein include reporting media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated by a device meter from a sensed signal. Disclosed example media monitoring methods also include, after receiving an indication that a first media signature of the first type is associated with first reference media, generating media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device. Disclosed example media monitoring methods further include, in response to detecting that a source of the media presented by the media device has changed, generating the media signatures of the first type to continue monitoring the media presented by the media device.

Methods and apparatus for inserting data a compressed data bitstream are disclosed. The methods and apparatus time shift first data in a first portion of the compressed data bitstream to increase a size of a second portion of the compressed data bitstream and insert second data in the second portion of the compressed data bitstream to form a modified compressed data bitstream.

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.

A system that incorporates teachings of the subject disclosure may include, for example, determining if a commercial contains one of metadata, close captioning information, recognizable speech in an audio component of the commercial, or a combination thereof. In response to determining that the commercial does not contain metadata, but does contain close captioning information, an advertised show is identified based on the close captioning information. Likewise, in response to determining that the commercial contains neither metadata, nor close captioning information, but does contain recognizable speech in an audio component of the commercial, the advertised show is identified based on the recognizable speech. Other embodiments are disclosed.
