20100046675 | METHODS AND APPARATUS FOR TRANSMITTING LAYERED AND NON-LAYERED DATA VIA LAYERED MODULATION - 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. | 02-25-2010 |
20100169910 | APPARATUS AND METHODS OF SELECTIVE COLLECTION AND SELECTIVE PRESENTATION OF CONTENT - Disclosed are apparatus and methods operable to distribute targeted content. Additionally, disclosed are corresponding apparatus and methods operable to selectively choose and cache selected ones from among the distributed targeted content, and to further choose ones from among the cached content to present on a device. In some aspects, selective caching of content may be based upon a match between predetermined content attribute information and predetermined profile information. Further, in some aspects, an indicator is operable to trigger the selective inclusion of one or more of the cached content in a presentation of other content, which may be based on a match between a desired content attribute associated with the indicator and the respective predetermined content attribute information of the cached content. | 07-01-2010 |
20100185717 | Method of improving control information acquisition latency by transmitting control information in individually decode-able packets - 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. | 07-22-2010 |
20100235717 | METHODS AND APPARATUS FOR PROVIDING LINEAR ERASURE CODES - Methods and apparatus for providing linear erasure codes. In one aspect, a method is provided for encoding a set of data values into a code symbol. The method includes determining an index sequence that defines selected data values to be used to generate the code symbol, and determining a value sequence that defines factors to be multiplied by the selected data values to generate the code symbol. The method also includes generating a packet header that describes the index sequence and the value sequence. | 09-16-2010 |
20110019632 | METHOD AND APPARATUS FOR RANKING OF MEDIA SERVICES AND PROGRAM PACKAGES - A method for improved presentation of media information for wireless communication is described herein. Media services and program packages are ranked and ranking information is delivered to a mobile device along with the media information. The ranking information is then used by the mobile device to arrange the media services in a ranked order. The ranking information can also be used to assign a default service that is displayed whenever the mobile device is activated or whenever a selection is made to view media content. The ranking information can also be used to arrange program packages in a ranked order for subscription purposes. | 01-27-2011 |

20110216666 | METHOD OF MULTIPLEXING OVER AN ERROR-PRONE WIRELESS BROADCAST CHANNEL - 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.

20110299587 | METHODS AND SYSTEMS FOR RESIZING MULTIMEDIA CONTENT BASED ON QUALITY AND RATE INFORMATION - 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. | 12-08-2011 |

20130177010 | TRANSMISSION OF OVERHEAD INFORMATION FOR RECEPTION OF MULTIPLE DATA STREAMS - 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. | 07-11-2013 |
