A corresponding electronic device comprises a receiver for scanning an FM frequency range to detect the above-mentioned type of available radio frequencies; a memory device for storing same; a controller for selecting one of the stored frequencies; an audio input interface for receiving audio data from the player; and a transmitter for modulating received audio data with FM and transmitting modulated audio data on a frequency selected by the controller.

Certain aspects of a method and system for providing wireless communication may comprise encoding within a single chip, FM audio data received by a FM radio. The encoded received FM audio data may be translated within the single chip to a Bluetooth compatible format. The translated received FM audio data may be communicated to at least one off-chip Bluetooth enabled device via the Bluetooth radio via at least one of the following: a synchronous connection oriented (SCO) link, an extended SCO (eSCO) link, and an advanced audio distribution profile (A2DP) link. The received FM audio data may be communicated via a dedicated link that couples the FM radio to a PCM interface that handles the encoding.

A method, system and computer program product for efficiently distributing video content. A peer-to-peer network and a content distribution network are used in combination to distribute video content. A content distribution network relies on servers distributed across the Internet to achieve high quality content delivery at a high cost. A peer-to-peer network distributes content among peers without incurring server side cost but may experience poor performance. The peer-to-peer network and the content distribution network are leveraged in a manner that achieves high content delivery and low cost by allowing the peer-to-peer network to serve as much content as possible while using the content distribution network to bootstrap the content in the peer-to-peer network and using it as a fallback whenever the peer-to-peer network has insufficient bandwidth, insufficient quality or when the missing piece of video content in the video buffer of the client device has an immediate deadline.

A system for providing multimedia content in accordance with one embodiment comprising an first electronic device for capturing multimedia content; a wireless services network for receiving the multimedia content from the first electronic device upon being sent from the electronic device; a blog database coupled to the wireless services network for storing the multimedia content; and a second electronic device adapted to receive the multimedia content stored in the database.

The present invention demonstrates how network-coding can be applied to a deterministic broadcast approach, resulting in significant reductions in the number of transmissions in the network. We propose two algorithms, that rely only on local two-hop topology information and make extensive use of opportunistic listening to reduce the number of transmissions: 1) a simple XOR-based coding algorithm and 2) a Reed-Solomon based coding algorithm that determines the optimal coding gain achievable for a coding algorithm that relies only on local information.

A multimedia content dissemination system is provided for mobile vehicles. A wireless vehicle communication network provides communication among mobile vehicles in the network. At least one host vehicle within the wireless vehicle communication network is selected by an authorized entity for disseminating multimedia content received by the authorized entity. The at least one host vehicle transmits an inquiry to target vehicles in the wireless vehicle communication network. The inquiry comprises a content profile that includes descriptors associated with the multimedia content for allowing target vehicles to determine whether an interest exists in the multimedia content. The at least one host vehicle transmits the multimedia content in encrypted form to an interested target vehicle for sampling the multimedia content. The interested target vehicle requests ongoing use of the multimedia content from the authorized entity in response to sampling the multimedia content. The authorized entity provides to the interested target vehicle a decryption key for authorizing ongoing use of the multimedia content.

A system comprises a first transceiver that wirelessly receives content. A set top box communicates with the first transceiver, separates the content into audio signals and video signals and outputs the audio signals to the first transceiver and the video signals to a display. The first transceiver wirelessly transmits the audio signals to an audio system.

Systems, method and apparatus are described for facilitating the collection of data from television receivers. First and second television receivers exchange data over a wireless communication link.

A multi-descrambler descrambles and encrypts each of the three first scrambled transport streams forming one second scrambled transport stream in correspondence with each of receivers.

A TV receiver transmits video data from its tuner unit to its monitor unit via wireless transmission by using a channel shared with radar. When the tuner unit receives a program to be viewed, a recorder/player starts recording of the received program. When wireless transmission of the received program cannot be started on time at the program start time because of detecting an unused channel for wireless transmission, or when a radar wave in the shared channel is detected after starting wireless transmission and then wireless data transmission is interrupted, the recorder/player plays back on a time-shift basis the program recorded on the recording medium, and the program data played back is transmitted to the monitor unit. The TV receiver is capable of preventing the user from missing a program that he wants to view even when wireless data transmission is interrupted.
