20090102968 | Color Metadata for a Downlink Data Channel - The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management. | 04-23-2009 |

20100123826 | Device, method and system transmitting video data between a video source and a video sink - Disclosed is a method, circuit and system for transmission of video data between a video source and a video sink. A video source transceiver may include: (1) a video source interface for receiving video data, optionally including one or more video synchronization signals functionally associated video source device; (2) a video source clock sampler for sampling a video clock parameter of received video data; (3) a video data buffer for buffering received video data prior to transmission; and (4) a video transmission circuit including packet size timing logic adapted to generate and transmit to a functionally associated video sink transceiver a value correlated to an expected data packet size based on video data stored in the video buffer. A video sink transceiver may include: (1) a video reception circuit adapted to receive a transmitted data packet, including one or more values generated by the packet size timing logic, and to regenerate a video frame; (2) video sync signal generation logic adapted to regenerate one or more video frame synchronization signals based on the one or more values generated by the video transmission circuit, and (3) a video sink interface for forwarding received video data, including one or more video clock and/or synchronization signals to a functionally associated video sink device. | 05-20-2010 |

A mark signal is added to the video signal and a mark ( | 06-24-2010 |
20100157153 | Upgrading Non-Volatile Storage Via an Encoded Video Signal - Systems for generating and transmitting a video stream that is encoded with program data such that when decoded can be executed to update non-volatile storage within a video based electronic device. Typically video based electronic devices are controlled by processors running software stored in writable, non-volatile storage. It is often desirable or necessary to update the software after the device has been shipped from a factory in order to correct a software failure discovered after shipment or to incorporate a new set of features. As many video based electronic devices have no common interface available to connect a computer, there is no ability to receive a software update. However, most video based electronic devices can be connected to a video source. Therefore, systems that allow a video based electronic device to receive, decode, and execute program data that is encoded within a video stream are presented. A method for encoding program code into a video stream is also presented. | 06-24-2010 |
20110164174 | Methods and apparatuses for implementing selective interference-filter pre-coding of main-service 8-VSB DTV Signals - Methods for discontinuing interference-filter pre-coding of 8-VSB digital television (DTV) signals during ancillary-service transmissions are disclosed that do not disrupt reception of main-service DTV signals by receivers already in use. Receivers are disclosed for receiving ancillary-service transmissions without interference-filter pre-coding, which receivers include adaptive channel-equalization filters and subsequent decoders for CCC. The subsequent decoders for CCC respond to data slicing of adaptive channel-equalization filter responses that avoid the reduction of signal-to-noise ratio (SNR) caused by post-comb filtering. Certain of these M/H receivers employ selective post-comb-filtering to flatten the frequency spectrum of main-service components of received 8-VSB DTV signals, while leaving the frequency spectrum of M/H-service components of received 8-VSB DTV signals as received. This is done to generate signal from which filter coefficients for the channel-equalization filters are determined. Certain of these M/H receivers employ decision-feedback equalization (DFE) techniques, which techniques are unaffected by selective interference-filter pre-coding. | 07-07-2011 |
20120242897 | METHOD AND SYSTEM FOR PREPROCESSING THE REGION OF VIDEO CONTAINING TEXT - A method and system for preprocessing text containing region of a video The invention provides a method and system for preprocessing the text containing region of video for improving the optical character recognition input. | 09-27-2012 |
20130250173 | NON-CLOSED CAPTION DATA TRANSPORT IN STANDARD CAPTION SERVICE - Methods, apparatuses, and non-transitory computer-readable storage mediums for providing and/or processing non-closed caption data. The reception apparatus includes a receiver, a parser, and a processor. The receiver receives closed caption service data. The closed caption service data includes closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6. The closed caption data includes closed caption text. The parser parses the non-closed caption data within the second service block having the different service number in the range of 1-6. The processor performs a function based on the parsed non-closed caption data. | 09-26-2013 |
