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.

System and method for controlling broadcast multimedia using plural wireless network connections

A system and method for multimedia data transmission including pooling, by a computer, at least first and second multimedia data streams together in a single channel, wherein each stream defines a respective sequence of frames and each frame includes at least a base layer and at least one enhancement layer; dynamically establishing, by the computer, first and second bit rates respectively associated with the first and second streams; and transmitting, by a transmitter, the at least first and second streams on the channel.

Joint transmission of multiple multimedia streams

User headphones are calibrated in real time to improve the reproduction accuracy of recorded audio content. Microphones of a type used to record the audio content (including their orientation and recording characteristics) are characterized to indicate a first audio coloration. Audio playback devices of a type used to process the audio content are characterized to indicate a second audio coloration. Headphones of a type corresponding to the user headphones are characterized to indicate a third audio coloration. An equalization signal is computed based on the audio colorations, and is applied to calibrate the user headphones during playback of the audio content. A database of the characterizations is maintained so that calibration of different models of headphones using different playback devices can be accomplished for audio content recorded using different models of microphones.

Calibration of headphones to improve accuracy of recorded audio content

Digital multimedia is broadcast by a wireless provider by first decoding incoming multimedia streams and then encoding each stream using one of at least two encoding parameter sets as appropriate for the particular user or groups of users to receive the stream.

Multimedia transcoding proxy server for wireless telecommunication system

System for providing hierarchical services in a data network. A method is provided for inserting content into a content stream for rendering on a device. The method includes obtaining one or more annotation parameters that comprise a content identifier, and determining an insertion point indicator that indicates a location in the content stream. The method also includes retrieving the content based on the content identifier, and inserting the content in the content stream at a location indicated by the insertion point indicator.

Methods and apparatus for providing hierarchical content flow in a data network

Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station may transmit multiple data streams on multiple data channels (or MLCs). The MLCs may be transmitted at different times and on different frequency subbands. The time-frequency location of each MLC may change over time. The overhead information indicates the time-frequency location of each MLC and may be sent as 'composite' and 'embedded' overhead information. The composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically in each super-frame. A wireless device receives the composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location. The embedded overhead information for each MLC indicates the time-frequency location of that MLC in the next super-frame and is transmitted along with the payload of the MLC in the current super-frame.

Transmission of overhead information for reception of multiple data streams

A wireless transmission system for multimedia information having plural layers includes a base station (BTS) and a mobile station (MS) that can select which layers to transmit based on reported channel conditions, mobile location, and/or forward error correction (FEC) used for a particular layer. A respective FEC rate and/or power level can be dynamically established for each layer by a mobile station dependent on available bandwidth and/or reception and decoding capability of the BTS.

Mobile station-centric method for managing bandwidth and QoS in error-prone system

A system device and method are provided which determine authorization for access to one or more services grouped together as a package of services without direct intervention of a wireless network provider or wired network access provider. This offers business proprietors, contractors for telecommunication services, service resellers, OEMs and service providers the ability to authorize users, particularly users of mobile communication terminals, hereafter referred to as the 'Owner,' access to package services. In this way a large package of features and applications can be available to a mobile device, but access to those features and applications can be controlled by the Owner thus providing the Owner with control over expenses related to accessing those features and applications. It also provides the Owner the ability to secure and prevent unauthorized access to features and applications which could allow an unauthorized user access to sensitive data and equipment.

Interactive control of access to services and capabilities of a mobile device

A system and method for partitioning a bandwidth of a single channel among plural multimedia streams in a time varying manner. The partitioning is undertaken by dynamically establishing first and second bit rates respectively associated with first and second multimedia streams.

Digital multimedia includes intraframe information and interframe information. In addition to sending separate complete intraframes that are referenced by interframes, some interframes ('hybrid' frames) contain partial intraframe information, so that if a complete intraframe is lost, referencing interframes can obtain at least some intraframe information from the hybrid frames.

System and method for partial intraframe encoding for wireless multimedia transmission

A multimedia stream is compressed in parallel by plural encoders, the compressed stream outputs of which are dynamically evaluated for merit. A best one of the compressed streams is transmitted, along with information regarding the particular compression algorithm that was used, so that the receiver's decoder can decompress the stream for presentation.
