摘要： Packets of information may be received in accordance with a protocol stack having a first portion (400) that contains a control layer and a stream layer, and a second portion (401) that contains a physical layer and a MAC layer. The second portion also maintains a group of inbound packets and respectively associated error statuses. The first portion invokes an application programming interface (API 1301,1302,1401,1402) to instruct the second portion to perform an action with respect to at least one of the inbound packets, which action is related to the error status associated with that packet.

摘要： Provided is a method and system for enhancing acquisition latency in a communications network. The method includes identifying control information associated with transmitted information and fragmenting the identified control information. Each fragment of control information is then associated with a corresponding transmission unit of the transmitted information. This process facilitates independent decoding and processing of the control information, which is embedded within physical layer packets.

摘要： 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.

摘要： A signal may be received in accordance with a protocol stack having a first portion (400) that contains a control layer and a stream layer, and a second portion (401) that contains a physical layer and a MAC layer. The first portion may invoke an application program interface (API 1402) to instruct the second portion to replace a current set of signal acquisition parameters with an initial set of signal acquisition parameters.

摘要： 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.

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.

摘要： 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.
