Provided is a method and system for transmitting information. The method includes determining stream length information for at least one data stream to be transmitted and associating the stream length information with a system parameter message. The system parameter message including the associated stream length information is transmitted separately from the data stream. This process facilitates de-multiplexing of individual streams and the processing of stream data even if one or more individual streams are received in error.

Method of multiplexing over an error-prone wireless broadcast channel

Provided is a method and system for determining sleep periods within a communications device configured to communicate via a network. The method includes analyzing at least one of two or more data fields related to a data unit and determining device sleep periods based upon the analysis. The analysis includes determining whether or not particular MediaFLO Logical Channel data (MLC) is present within an overhead information symbols channel. If MLC data is not present, the device sleeps for a predetermined amount of time.

Method of enabling power savings when no data is being transmitted on a media logical channel

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.

Method and system for achieving faster device operation by logical separation of control information

A signal may be received in accordance with a protocol stack having a first portion () that contains a control layer and a stream layer, and a second portion () that contains a physical layer and a MAC layer. The first portion may invoke an application program interface (API) to instruct the second portion to replace a current set of signal acquisition parameters with an initial set of signal acquisition parameters.

Application programming interface (API) for restoring a default scan list in a wireless communications receiver

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.

Fast channel switching in a multimedia broadcast system

A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation.
