Disclosed are methods and systems to help disambiguate channel identification in a scenario where a video fingerprint of media content matches multiple reference video fingerprints corresponding respectively with multiple different channels. Given such a multi-match situation, an entity could disambiguate based on an audio component of the media content, such as by further determining that an audio fingerprint of the media content at issue matches an audio fingerprint of just one of the multiple channels, thereby establishing that that is the channel on which the media content being rendered by the media presentation device is arriving.

Disclosed is a system and method for determining output transmission power for radio signal transmission, from an interception transmitter and from an announcement transmitter, respectively, to at least one announcement receiver, wherein each announcement receiver is in a respective motor vehicle, the method comprising: receiving an input signal to be suppressed; determining a first field strength of the input signal, at a first frequency f.sub.I, at a position POS.sub.R; determining a first transmission power of a first radio signal, intended to be transmitted by the interception transmitter, needed to suppress the input signal at an interception transmission distance; determining a second field strength of at least one of atmospheric noise and the input signal at a second frequency f.sub.A, at the position POSR; and determining a second transmission power of second radio signal comprising an announcement to be transmitted by the announcement transmitter to the at least one announcement receiver.

A computing system compares various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system determines that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. In response, the computing system identifies a fingerprint feature that could define a distinction between the reference fingerprints, and the computing system resolves the multi-match based on the identified feature, thereby determining the channel carrying the media stream being rendered by the media presentation device. And the server then takes channel-specific action based on the determined channel.

The present technology relates to a reception apparatus, a transmission apparatus, and a data processing method that enable a frequency scan to be performed at a higher speed. The reception apparatus can receive a broadcast wave, perform the frequency scan on the broadcast wave on the basis of the number of providers information indicating the number of broadcasting providers providing a service in the same frequency band, and generate channel selection information for selecting the service, thereby enabling the frequency scan at a higher speed. The present technology is applicable to, for example, a receiver capable of receiving digital broadcasting.

A transmission/reception system includes a transmitter and a receiver. The transmitter includes a first circuit that: acquires plural pieces of broadcast image data; categorizes the broadcast image data at least into first and second groups; generates program guide screen data that switches between first and second program guide screen data; generates temporal information about the predetermined time interval and broadcast program identification information; and transmits the screen data and the information. The receiver includes a second circuit that: receives the data and the information; outputs the program guide screen data; detects, when any one of the display frames is selected by a user operation, broadcast program identification information contained in the first or second program guide screen data; and performs control in such a way that the broadcast image data corresponding to the detected broadcast program identification information are output from the image data output device.

Various arrangements for integrating over-the-air (OTA) television programming with streaming media are presented. An OTA integration module may request, from an OTA tuner device, a stream of an OTA television channel, wherein the OTA television channel is broadcast over a geographic region on the VHF band or UHF band. The OTA integration module may receive, from the OTA tuner device, the stream of the OTA television channel. The OTA integration module may provide, to a media presentation application, the stream of the OTA television channel. The media presentation application executed by the streaming media player device may output the steam of the OTA television channel for presentation.
