  • Patent number: 10083700
    Abstract: The present technique relates to a decoding device, a decoding method, an encoding device, an encoding method, and a program which can obtain a high-quality realistic sound. The encoding device stores speaker arrangement information in a comment region in a PCE of an encoded bit stream and stores a synchronous word and identification information in the comment region such that other public comments and the speaker arrangement information stored in the comment region can be distinguished from each other. When an encoded bit stream is decoded, it is determined whether the speaker arrangement information is stored on the basis of the synchronous word and the identification information stored in the comment region. Audio data included in the encoded bit stream is output according to the arrangement of the speakers corresponding to the determination result. The present technique can be applied to an encoding device.

  • Patent number: 9516526
    Abstract: A method and system are provided for visualizing and analyzing spectrum assets. License, channel, and lease data from a communications authority is collected and formatted into individual polygon maps. The maps could be drawn according to county or state boundaries, or by some other mapping standard. The maps are then divided and redrawn into several market service areas and several basic trading areas. The maps are also divided and redrawn according to the bandwidth spectrum of one or more channels. Since the maps are drawn with several different boundary conditions, the layout of all of the maps result in some maps being partially overlaid onto other maps for the same region. These regions containing partially overlaid maps are redefined as superblocks. Each superblock contains all of the data from each overlaid map portion for that particular region.

    Abstract: An HDMI® source determines whether or not an HDMI® sink can receive a sub-signal based on VSDB of E-EDID. When the HDMI® sink can receive the sub-signal, the HDMI® source adds a sub-signal to pixel data of a main image composed of pixel data whose number of bits is smaller than that of transmission pixel data transmitted by a transmitter, thereby constructing transmission pixel data. This data is transmitted by the transmitter through TMDS channels #0 to #2. Furthermore, the HDMI® source transmits a general control packet containing sub-signal information indicating whether or not the sub-signal is contained in the transmission pixel data in the control period of a vertical blanking period.

  • Patent number: 7894709
    Abstract: A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. A best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output.

  • Patent number: 7830451
    Abstract: An image processing apparatus and an image processing method are provided for enhancing the picture quality of images by extracting additional information from non-standard signals without an error. A signal determination unit receives an image signal including an image interval containing an image and an additional information interval containing additional information regarding the image. A determination is made as to whether the additional information exists in the additional information interval. An additional information extractor extracts and outputs the additional information from the additional information interval, if the signal determination unit determines that the additional information exists in the additional information interval.

  • Publication number: 20100157153
    Abstract: 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.

  • Patent number: 7697066
    Abstract: An apparatus (10) and method (40) is provided for detecting data within the vertical blanking interval (VBI) lines of a video or television signal. The VBI data detection (18) samples (42) at least one point from the VBI lines of a video signal and compares (44) at least one data characteristic, such as luminance, from the sample to a threshold to determine if the sample contains VBI data. If the sample contains VBI data, the VBI line from which the sample was taken is routed (46) to the processing unit of a video processing device. If no samples from a VBI line are found to contain VBI data, the VBI line is not processed further. The VBI data detection apparatus improves processing efficiency and resource allocation by allowing only those VBI lines containing VBI data to be processed by the video processing device.

    Abstract: A method, apparatus, system and machine-readable medium for generating a composite output image based upon multiple input images. In one embodiment, a first display location on a display panel is located. A first function is performed to generate a first pixel of the output image for display at the first display location if a first image and a second image are both active at the first display location. A second function is performed to generate the first pixel of the output image if only the first image or only the second image is active at the first display location. In one embodiment, the first image is active at the first display location if the first display location is located within a first display area on the display panel where the first image is to be displayed, the second image is active at the first display location if the first display location is located within a second display area on the display panel where the second image is to be displayed.

The method comprises generating one or more digital symbols at a first frequency, shaping the one or more digital symbols into one or more VBI data samples, first determining a first value that specifies a number of possible points that may be interpolated between two consecutive data samples of the one or more VBI data samples, and second determining a second value that is equal to one plus the number of points skipped before a point of the possible points is selected, and outputting the selected point based on an output frequency. The system may be described as a generalized VBI waveform generator comprising a symbol generator, a shaping filter, and a variable linear interpolator.

  • Patent number: 7336318
    Abstract: An apparatus and method for facilitating program changes. The apparatus and method include a controller for detecting a change program request and for outputting change event data when a change event is detected. A non-active video information replacement module is coupled to the controller for receiving non-active video information and the change event data. When the replacement module receives change event data, a clear code generator generates clear code data that replaces non-active video information, and the non-active video information replacement module generates modified non-active video information. The modified non-active video information is provided to an output stage, whereupon the clear code data resets a non-active video information field within a display device, thereby preventing the display of erroneous information by a display within the output stage. Thereupon, clear code data is synthetically inserted within non-active video information upon the occurrence of a change event.
