摘要:
A wireless mobile device, wireless communication system and method for automatically switching data channels in the wireless mobile device uses a content stamp matrix that includes content features and time stamps of services available on the data channels to determine at least one of the content features that matches any of reference content features in a content feature preference list. A matched content feature is then used to automatically switch to a data channel of a service associated with the matched content feature using a time stamp that correspond to the matched content feature based on priority of a matched reference content feature in the content feature preference list.

First run notification of a presentation. An indicator on the network guide or recorded programs list would allow a user to quickly distinguish between first run presentations that have never before been available at an earlier time in the program guide and presentations that have been previously shown. The first run presentations could be distinguished by an indicator such as background color, a special icon, text color, or specific text.

Systems, methods, apparatuses, user interfaces and computer program products provide social and interactive applications for mass media based on real-time ambient-audio and/or video identification. In some implementations, a method includes: receiving descriptors identifying ambient audio associated with a media broadcast; comparing the descriptors to one or more reference descriptors; and determining a rating for the media broadcast based at least in part on the results of the comparison.

The present invention describes a method executed by a digital signal processing system for identifying a known audio or video programming without any reliance on a tandem video signal or normative markers in the signal indicating a known time in the program. The method generates a signature associated with the known signal being identified by an identification index comprising transforming at least one time frame of the signal into frequency domain; calculating for each frequency band a signal numeric value; and store the signature in a computer database.

Music and non-music portions in an audio stream are identified. The audio stream is digitized and segmented into frames. Selected frames are passed through a filter bank which includes filters having bandwidths approximately proportional to their center frequencies. The spectral flux for each selected frame is calculated and smoothed. Frames having a smoothed spectral flux below a threshold value are associated with music, and frames having a smoothed spectral flux above a threshold value are associated with non-music.

A method and system for content sampling and identification is presented. A data stream is recorded, and samples of the stream are identified. Samples can be initially taken at random for identification. Once a sample is identified and segmented within the data stream, the next time to sample may be calculated to be outside the time frame of the identified sample. Thus, the sampling period can be adaptively adjusted to be at times after identified tracks.

A method for selection of content on a device allows a radio to scan (406) for desired (e.g. audio) selections being broadcast in accordance with a defined priority list that has been pre-stored (404). A found selection is played (408) in order of priority and then placed back (410) in the priority list in accordance with a prioritization logic. Desired content is identified by a digital signature or audio clip, for example. Associated with the identifier can be user interface settings (400), such as audio controls, and even vehicle settings such as window position, sun roof, moon roof, or convertible roof top, for example. The user interface can be used to store (402) and sort identifiers and to provide control settings to the user in audio or video format.

Systems and methods are provided for gathering audience measurement data relating to receipt of and/or exposure to audio data by an audience member. Audio data is monitored to detect a monitoring code. Based on detection of the monitoring code, a signature characterizing the audio data is extracted.

Methods and apparatus to collect audience information associated with a media presentation are described herein. A disclosed system includes a base metering device and at least one portable metering device. The base metering device is disposed within a viewing area of one of a plurality of media presentation devices. Further, the base metering device is configured to emit a signal. The at least one portable metering device is configured to receive the signal when located within the viewing area and to collect viewing data reflecting viewing of any of the plurality of media presentation devices by at least one viewer. Accordingly, the at least one portable metering device uses the signal to identify all or a subset of the viewing data as being associated with viewing of the one of the plurality of media presentation devices depending on whether the signal is received.
摘要:
A method of use provides an extremely efficient manner of ordering a radio program occurring at approximately the time presented, minimizing the need to remember any details. The method is embodied in a range of tactile and voice controls which people in motion need to have. Security options include voice signatures, button sequences and fingerprint identification. User feedback is embodied in both audio and visual display formats. A method of controlling a radio is claimed which provides for placing an order, querying the ordering system for additional information, initilizing a user's identifying signature, initializing a session by identifying a user, if the user is not properly identified, blocking access to ordering, and in certain embodiments, calling the police. A radio device is claimed supporting an IF signal source containing essential information on the radio program, an embedded controller, user interface as well as a radio transceiver by which the ordering transaction is carried out.
