Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
