A method and apparatus to improve error resiliency in processing a multimedia bitstream is described. A directory of header information is generated for a multimedia bitstream. The directory information comprises packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream. A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within and subsequent to erroneous data in the received bitstream. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of the multimedia data.

A wireless communication method and corresponding apparatus for modifying a subscription is described, the method comprising wirelessly receiving subscription information describing a plurality of program packages and relationships between the program packages, the relationships including at least a first reference from a first program package including at least a first service to a second program package including at least the first service and a second service, the first reference indicating that a subscription to the first program package is required prior to the second program package being determined as available for subscription, determining the set of program packages available for selection based on the relationships between the packages, displaying the set of program packages determined to be available for selection and allowing a selection of one or more displayed packages from the set, wherein the subscription is modified as a result of the selection. As well as the corresponding method an apparatus for providing the subscription information is described.

Methods and apparatus for enhanced delivery of content over a data network. In an aspect, a method is provided for transmitting services over a network. The method includes receiving one or more services having associated delivery requirements, determining that network bandwidth is available to meet the delivery requirements, and allocating the network bandwidth to the one or more services based on the delivery requirements to produce network bandwidth allocations. In an aspect, an apparatus is provided that includes receiving logic configured to receive one or more services having associated delivery requirements, and multiplexer logic configured to determine that network bandwidth is available to meet the delivery requirements, and to allocate the network bandwidth to the one or more services based on the delivery requirements to produce network bandwidth allocations.

Multiplexer to transmitter interface protocol. A method for a data interface protocol is provided that includes receiving a first packet stream having at least one overhead information symbol (OIS) group and at least one multicast logical channel (MLC) group, and mapping each OIS group to an OIS descriptor packet and at least one OIS payload packet. The method also includes mapping each MLC group to an MLC descriptor packet and at least one MLC payload packet, and outputting the OIS descriptor, OIS payload, MLC descriptor, and MLC payload packets in a second packet stream. An apparatus includes input logic to receive the first packet stream, processing logic to map each OIS group to an OIS descriptor packet an OIS payload packet, and each MLC group to an MLC descriptor packet and an MLC payload packet, and output logic to output the mapped packets in a second packet stream.

In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

A wireless broadcast system is disclosed. The wireless broadcast system includes a transmitter for broadcasting to a wireless communications device. The transmitter receives a plurality of streams on a logical channel, wherein one of the streams contains signaling. The transmitter arranges the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel. The wireless communications device receives the streams broadcast on a logical channel broadcast in a frame, and acquires the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.

Media distribution systems may include methods and apparatus to perform memory management on a wireless devices configured to receive non-real time portions of media services. Such methods and apparatus may be based upon an allowable capacity of presentations storable in device memory, as well as on a required memory associated with each presentation in a media service. Such methods and apparatus allow a device to subscribe to a media service based upon sufficient available memory in the device to support the service.
摘要:
Provided is a method and system for managing device operations. The method includes dividing control information into two or more portions, each portion being associated with a unique control sequence number. Each of the associated control sequence numbers is examined during an update cycle to determine which of the portions must be updated. The control sequence number includes information related to control information updates.
