A built in FM Transmitter and/or VHF Transmitter, referred to as “transmitter”, for cellular, portable, or other wireless communication devices, referred to as “cell phone”, establishing stored voice, music or video over home or automobile entertainment centers, referred to as “entertainment centers”. The cellular or portable phone would have music or video stored on or transmitted to it via physical or wireless means. The cell phone has a built in low power transmitter for the expressed purpose of transmitting stored voice, music or video to nearby entertainment centers. There could be a special controller or device on the entertainment system for control, encryption or security of FM transmissions. An interface between the cell phone and the entertainment center would not be required. The transmitter and its controls can be housed in the cellular phone. There is no physical connection between the cellular phone and the entertainment center located in an automobile or elsewhere. The transmitter can be controlled through hardware or software housed or programmed into the cell phone.

A network for wireless transmission of data includes a source access point, a destination device and a plurality of wireless repeaters that provide a transmission link between the source access point and the destination device. The plurality of access points each includes a single transceiver with separate transmitter and receiver sections operable to simultaneously transmit and receive data on different frequency channels. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

An Automatic Purchase System (APS) provides a radio broadcast listener with the ability to conveniently purchase 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 such as those conducted by public radio, 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 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 the APS server software on a Data Server located at the broadcast site, a remote site or both for purposes of redundancy. Transmission of purchase requests from a Technology Enabled Radio (TER) is provided via wireless transmission, or by accessing the Internet using a personal computer or through a cellular or wireless phone.

A situational awareness system includes a first local network having a plurality of digital communication devices, each device capable of gathering information pertinent to an area in proximity of the device and providing information to a control station capable of collaborating the information and provide such information to the devices on the local network; a first regional network having a plurality of local networks, including the first local network, within an area of responsibility, the first regional network having a regional control station capable of collaborating information from the devices and provide said information to devices on the local network; and a central network having a plurality of regional networks including the first regional network, the central network having a central control station capable of collaborating information from the regional control stations and provide the information to devices on a local network.

A method and system for optimizing performance in a data-over-cable system. The method includes determining parameters for data transmission on an upstream channel of the data-over-cable system, and negotiating use of the parameters. A measurement is made of a signal-to-noise ratio (“SNR”) on the upstream channel. Associated with the SNR and a target packet-error-ratio (“PER”) are parameters that provide optimal data throughput. The parameters, such as symbol rate, type of modulation, or amount of error correction, are used to construct a message that is sent to the cable modems. The message instructs the cable modems to reconfigure themselves to transmit according to the parameters. The reconfiguration helps ensure optimal performance.

A method and system for providing customized content for a plurality of users is provided. In one embodiment, the method may comprise receiving user information from a plurality of users including location information of each user. For each of the plurality of users, the method may include constructing first compilation data that includes information of a first plurality of content elements and wherein the first compilation data constructed for each use may be different. For each of the plurality of users, the method may further include presenting the content elements of the first compilation data to each of the plurality of respective users. The first compilation data may be constructed from a first template, and the method may further comprise receiving feedback from a set of the users, modifying the respective first template of the set of users based on the feedback, and constructing second compilation data that includes information of a second plurality of content elements for the set of users. Finally, the content elements may be scheduled to be transmitted to the user device, such as a mobile telephone, according to rules configured to reduce peak communications network utilization.

A wireless network service delivers audio tracks to a user via a mobile wireless terminal. A server maintains a plurality of audio tracks, wherein each audio track is stored in conjunction with a respective cadence tag. A cadence evaluator identifies a substantially instantaneous user status and selects a cadence tag corresponding to the user status. The server streams a selected audio track having a cadence tag matching the selected cadence tag, and the mobile wireless terminal plays it back to the user. The cadence can be selected to match a desired pace of an athletic workout, a desired heart rate, or the particular geographic surroundings, for example.

A digital broadcast transmitting/receiving system and a signal processing method thereof that can improve the receiving performance of the system. A digital broadcast transmitter has a randomizer to randomize an input data stream which has null bytes being inserted at a specified position, a multiplexer to output a data stream formed by inserting specified known data into the position of the null bytes of the randomized data stream, an encoder to encode the data stream outputted from the multiplexer, and a modulator/RF-converter to modulate the encoded data, RF-convert the modulated data and transmit the RF-converted data. The receiving performance of the digital broadcast transmitting/receiving system can be improved even in a multi-path channel by detecting the known data from the received signal and using the known data in synchronization and equalization in a digital broadcast receiver.

Digital multimedia is broadcast to wireless receivers on a unidirectional wireless broadcast channel, while control data necessary for presentation of the multimedia is provided on a bidirectional, point-to-point wireless link.

A radio station (1) transmits a radio programme using a VHF-FM singal which is received by a WAP-enabled mobile commnicaitons device (3). The signal includes radio datea service (RDS) data which includes the URL of a web-site associated with the radio station. The user accesses the web-page and participates in an opinion poll by casting a vote. The server logs the vote. The radio station counts the votes and announces the votes while the radio programme is still on air.

An audio reproduction system includes a plurality of mobile devices, such as mobiles phones. Each of the mobile devices includes a loudspeaker, memory for storing audio data, and instructions, stored in memory, for prompting the plurality of mobile devices to each output at least a portion of an audio data file to the loudspeaker of the respective mobile device. A processor is configured for executing the instructions, thereby enabling contemporaneous play of the audio data file by the plurality of mobile devices.
