20090129483 | Artifact-Free Displaying of MPEG-2 Video in the Progressive-Refresh Mode - A method and apparatus for decoding and displaying a bitstream, such as, for example, Motorola/GI HITS bitstream, is provided. The method avoids displaying artifacts caused by displaying incompletely decoded pictures after channel acquisition. After the channel acquisition, an entry picture, a P-picture with the refreshed I-slices at the top of the picture, is first displayed with all pixels below the refreshed I-slices zeroed (blacked) out. Then the subsequent P-pictures are displayed with all pixels below their respective refreshed I-slices zeroed out. Once a P-picture has been completely decoded, normal decoding process is started. | 05-21-2009 |

At least a portion of the prefix portion and the payload portion of the DSS transport packet may be mapped into at least a portion of the header portion and the payload portion of the DVB transport packet. At least a portion of the payload of the DSS transport packet may be aligned with at least a portion of the payload portion of the DVB transport packet. | 07-02-2009 |

20090196347 | METHOD AND APPARATUS FOR IMPLEMENTING REDUCED MEMORY MODE FOR HIGH-DEFINITION TELEVISION - A method and apparatus are provided for implementing an enhanced reduced memory mode (RMM) of decoding HDTV MPEG-2 video stream. In one instance, the RMM mode is adaptively enabled with up/down conversion by using the picture-type information. In another instance, the RMM mode is provided by performing anchor-frame compression/decompression by using adaptive DPCM technique with picture-type information. The quantization (PCM) tables are generated using the Lloyd algorithm. Further, the predictor for each pixel is determined by a use of the Graham rule. | 08-06-2009 |
20090296822 | Reduced Memory Mode Video Decode - A method and system to decode a video stream are provided. The method comprises receiving macroblocks, filtering and decimating the macroblocks to create decimated macroblocks and storing the decimated macroblocks. The method further comprises creating a decimated reference block from one or more decimated macroblocks of a decimated reference picture and interpolating selected pixels of the decimated reference block to create an interpolated reference block. The method further comprises pre-processing selected columns of the interpolated reference block to create a processed reference block for motion compensation. | 12-03-2009 |
20100020887 | Multiple time-base clock for processing multiple satellite signals - An integrated receiver with multiple, independently synchronized clock signals for multiple channel transport stream decoding and delivery substantially implemented on a single CMOS integrated circuit is described. An integrated circuit that services two satellite programs must generate and distribute corresponding time domain clocks to the various components of the integrated circuit. The transport block that receives one or more satellite signals from a demodulating block will extract program clock recover values from each signal being decoded and use these values to produce an error signal or control word that serves as an input to a clock generator. Based upon this input, the clock circuit will produce a corresponding time domain clock for each channel serviced by the integrated circuit. The output of the clock circuit is distributed to the various processing blocks within the integrated circuit that operate upon channel content received and processed by the transport block. | 01-28-2010 |
20110013887 | Command packets for personal video recorder - Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data. | 01-20-2011 |
20110316972 | DISPLAYING GRAPHICS WITH THREE DIMENSIONAL VIDEO - Methods, systems, and apparatuses are provided for enabling three-dimensional video and additional graphics to be displayed together without interference. A media content signal is received. The media content signal includes graphics overlay data representative of a graphics overlay, first image data representative of a first image, and second image data representative of a second image. The first and second images are representative of three-dimensional content. An interference is detected between the graphics overlay and the three-dimensional content in a three-dimensional view volume. At least one of the graphics overlay data, the first image data, or the second image data is modified to cause the graphics overlay and the three-dimensional content to be non-interfering. The non-interfering graphics overlay and three-dimensional content are enabled to be viewed by a viewer based on the modified graphics overlay data, first image data, and/or second image data. | 12-29-2011 |

20130308927 | APPARATUS AND METHOD OF SEAMLESS SWITCHING BETWEEN A LIVE DTV DECODING AND A PVR PLAYBACK - Methods and apparatus for switching between a live video decoding and a recorded playback in a digital video and recording system. A received video data stream is transmitted to a first-in first-out video decoder buffer without first looping the video data stream through a playback buffer. The video data stream is transmitted from the video decoder buffer to a video decoder. If a “pause” command is received, the video data stream is transmitted to a first-in first-out playback buffer, while continuing to transmit the video data stream to the video decoder buffer. Transmission of the video data stream to the video decoder buffer is halted when the video decoder buffer fills up. The last byte of the video data stream that was transmitted to the video decoder buffer is marked. If a “play” command is received, the video data stored in the video decoder buffer is transmitted to the video decoder. The video data stored in the playback buffer is transmitted to the video decoder buffer starting at a point immediately after the data element that was marked previously. | 11-21-2013 |
