20100130122 | APPARATUS AND METHOD FOR PERFORMING POWER MANAGMENT IN A RECEIVER - A Digital Video Broadcasting-Handheld (DVB-H) system comprises a head-end and at least one receiver. The head-end uses the File Delivery over Unidirectional Transport (FLUTE) protocol for transmitting an electronic service guide (ESG) and content to the receiver. The receiver determines a time delay for receiving content as a function of a value of a PublishedStartTime parameter from the ESG and the actual time the receiver receives the content. Using this time delay, the receiver forms a time estimate for receiving selected content as a function of a value of a PublishedStartTime parameter from the ESG for the selected content and the determined time delay. The receiver then performs power, management such that during those intervals of time that the receiver is not expected to receive the selected content the receiver can reduce power. | 05-27-2010 |

The ESG information assists a client device in obtaining file information before the file is actually transmitted by the source of the same. In this manner, the power supply of the user device can be managed more efficiently and provide the user with the ability to make storage determinations at their user device before expending the power resources necessary to obtain (i.e., download) and store a particular file of interest to the user without requiring any user intervention. | 11-04-2010 |
20110029684 | STAGGERCASTING WITH TEMPORAL SCALABILITY - In the transmission of streams of data, such as coded video, staggercasting, in which a primary and a secondary stream are transmitted at some relative time offset (i.e., “staggered”), allows a receiver to pre-buffer frames of the secondary stream to replace frames of the primary stream that may have been lost in transmission. In an illustrative implementation, staggercasting is performed in which the secondary stream contains a subset of the coded video frames transmitted in the primary stream. The primary stream contains reference frames, which are essential to properly decoding the video data, as well as disposable frames which are not. The secondary stream, however, contains copies of the reference frames and may contain copies of some of the disposable frames or no disposable frames at all. When frames of an interleaved stream of the primary and secondary streams are lost, such an arrangement will allow reconstruction at the receiver of an uninterrupted video stream at a temporarily reduced frame rate. | 02-03-2011 |
20110085551 | STAGGERCASTING METHOD AND APPARATUS USING TYPE OF SERVICE (TOS) INFORMATION - A stagger transmitter manipulates the Type of Service (TOS) information contained in packets transmitted therefrom. Downstream network devices, such as a network Multiplexer (MUX), use the TOS information to handle the packets. A MUX controls the bandwidth allocated to each of the original and staggered streams in accordance with the TOS information. The stagger transmitter manipulates the TOS information of packets in accordance with other information contained in the packets, such as Network Abstraction Layer (NAL) information. As such, the staggered stream copies of more important packets, as indicated by their NAL information, can have their TOS information set by the stagger transmitter so that a network MUX will forward such staggered packets in addition to the original packets, thereby providing redundancy and error protection for such packets. | 04-14-2011 |
20110090958 | NETWORK ABSTRACTION LAYER (NAL)-AWARE MULTIPLEXER WITH FEEDBACK - Advanced multiplexing methods and apparatus that are especially useful in multiplexing variable bit rate input video streams onto a fixed bandwidth output stream with minimum effect on video quality are described. A multiplexer provides feedback to a stagger transmitter to help it maintain its output bit rate. In addition, the stagger transmitter parses Network Abstraction Layers (NALs) from the given streams and makes decisions on which NALs to forward to the MUX. | 04-21-2011 |
20110099577 | FILTERING OF DYNAMIC SERVICES IN CACHED SERVICE ACQUISITION DATA - At a receiving device after a power-on or physical channel change, the physical channel is monitored for activity relating to services for which electronic service guide (ESG) data had been previously cached. The ESG data for a service will include some service identification information, such as an interne protocol (IP) address associated with the service. The monitoring of the physical channel for activity related to a service can be done by listening for the IP address associated with the service. If activity is detected, the service is determined to be active and its cached ESG data valid. Service acquisition data included in the cached ESG data is used to present the service to the user. The invention thus allows the presentation of services to the user using cached ESG data as soon as the services are detected to be active, without the need to wait for the reception of fresh ESG data. The cached ESG data of services for which no activity is detected is not used and may be deleted from the cache after a certain period. | 04-28-2011 |

20110214147 | Method for determining content for a personal channel - Creating a listing of suggested content and programming for a virtual channel is performed by generating rankings of previously viewed or accessed content. The method determines whether such content is either cyclical in nature as being related to a series or if such content is broadcasted less frequently. Once such rankings are determined, the listings of suggested (other) content will have a number of entries per time segment which represent the highest ranked suggested per time segment | 09-01-2011 |
20120113993 | BACKWARD LOOKING ROBUST HEADER COMPRESSION RECEIVER - Robust Header Compression (ROHC) offers a way to compress packet header information for more efficient transmission of data. The compression is achieved through various confidence modes set up by the transmitter and the receiver. The Initialization and Refresh state (IR) is the first state of the compressor. This provides a complete, uncompressed context of the data that is being transmitted. In typically operation, the ROHC compressor will periodically transmit IR packets providing context information allowing the ROHC decompressor to decompress one or more packets following the IR packet. However, under certain conditions such as decompressor start-up, it is possible for the decompressor to miss an IR packet. Exemplary methods and apparatus are described in which a decompressor uses a later-received IR packet to decompress earlier packets for which the decompressor had not received context information. | 05-10-2012 |
