A system and method for broadcast response generally employing RDS, DARC, or similar technology is provided, including a method for responding to a broadcast comprising extracting an event identifier from a broadcast signal; detecting a response by a user to the broadcast signal; polling a communications device to determine a user identifier; and communicating the event identifier and the user identifier when the user response is detected.

A method for user equipment to improve position information of one or more communication devices including obtaining map information about positions of the one or more communication devices, determining radio channel information about the one or more communication devices by analyzing a radio channel, and generating a node map having improved position information of the one or more communication devices using the map information and the radio channel information.

A receiver and associated methods are described. The receiver comprises a first oscillator 14, a second oscillator 16, a controller 18 operable to control frequencies to which the first and second oscillators are tuned, and a discrimination circuit 24 operable to receive and monitor transmitted signals; wherein the discrimination circuit is configured to receive a signal at a first transmission frequency determined based on a first tuned frequency to which the first oscillator is tuned, and to determine, in a capture time period, whether data is being transmitted at the first transmission frequency; wherein the controller is configured to tune, in a tuning time period, the second oscillator to a second tuned frequency; and wherein the tuning time period is shorter than the capture time period.

A system and method for broadcast response generally employing RDS, DARC, or similar technology is provided, including a method for responding to a broadcast comprising extracting an event identifier from a broadcast signal; detecting a response by a user to the broadcast signal; polling a communications device to determine a user identifier; and communicating the event identifier and the user identifier when the user response is detected.

A method for decoding the name of detected radio stations, the method being implemented by a receiving system including at least one radio receiver, each of the received radio signals including a digital datum corresponding, at least intermittently, to the name of the radio station, the method including the following steps: for each radio station belonging to a list of radio stations preselected from the detected radio stations, a first decoding of the digital datum at a first sampling frequency, in order to determine a probable name; for any detected radio station not belonging to the list of preselected radio stations, a second decoding of the digital datum at a second sampling frequency lower than the first, in order to determine a probable name; and measuring a quality of the radio signal and inhibiting the first and second decodings if the quality of the signal drops below a preset threshold.

A system and method for broadcast response generally employing RDS, DARC, or similar technology is provided, including a method for responding to a broadcast comprising extracting an event identifier from a broadcast signal; detecting a response by a user to the broadcast signal; polling a communications device to determine a user identifier; and communicating the event identifier and the user identifier when the user response is detected.

Apparatus, methods, processors and computer programs products for generating or processing a broadcast radio transmission comprising multimedia content and supplemental information corresponding to the multimedia content. The supplemental information comprises a selected data group from a plurality of predetermined data groups each comprising different data, wherein the selected data group further comprises a tag and a corresponding set of text data operable to initiate a predetermined capability of a wireless device.

A broadcast response system provides, e.g., a radio broadcast listener with the ability to obtain media content such as music or speech while listening to the radio. The user can respond to items in the radio broadcast such as advertisements, fund raising drives, or interactive listener polls during the broadcast. Data such as song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored, can be transmitted using, e.g., the RBDS/RDS data stream. A reference number representing song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored can also be employed for ease of implementation. This reference number can reside in a lookup table to be accessed by broadcast response server.

Implementing and applying a database with radio station information that is gathered from client devices as stations become available to a plurality of users (i.e., “crowd sourced” radio station information) and allowing for a client device to download only the radio station information that is pertinent to the travel route of the user and/or radio station selection criteria associated with the client device or the user. Radio station information can be rendered via a graphical interface of a client device to allow the user to informatively select a new radio station, either before or as a current radio signal degrades to the point of being unusable. Radio station information may be rendered to cause the user's terrestrial radio to tune to a new station.

Information about desired songs is collected on a portable memory device in communication with a radio tuner. The radio tuner may receive signals from a terrestrial or satellite digital radio transmission, or from an analog radio transmission. These transmissions may include text data about the current song being played. Upon activation by a user, song data is stored on the memory device. The memory device is then connected to a computer system, which uses software to extract the song data and uniquely identify the song. The identified songs are stored on the computer system, and can be used to allow the user easy access to the identified song through prior art techniques. If no textual data is stored about a song, the song is identified by identifying the radio station that played the song and the time at which the user activated the mechanism.
