  • Publication number: 20200021321
    Abstract: An in-service radar detection unit for a wireless analog video receiver includes a channel estimator, a signal recovery vector creator, a signal estimator, a radar detector, and a control transmitter. The channel estimator generates a channel estimation between a transmitter and a receiver from a plurality of signals received on a plurality of antennas. The signal recovery vector creator creates a non-zero nulling vector from the channel estimation. The signal estimator utilizes the nulling vector to restore an additional signal, other than an analog video, from the received signals. The radar detector detects a radar signal in the additional signal, and the control transmitter transmits an indication of the detected radar signal using at least one of the antennas.

  • Patent number: 9462283
    Abstract: A method includes, in an encoder, dividing an image into blocks, and producing respective compressed descriptions of the blocks. First data, which contains at least some of the compressed descriptions, is generated such that a compressed description of each block within the first data is accessible irrespective of the compressed descriptions of the other blocks. Second data, which contains at least a portion of the compressed descriptions or of the blocks and has a better error resilience than the first data, is also generated. The first and second data are stored in a memory. At a decoder, the first and second data are read from the memory, and the image is reconstructed from the read first and second data.

  • Patent number: 8599311
    Abstract: Disclosed are methods, circuits, devices and associated executable code for facilitating transmission, reception and presentation (e.g. rendering) of video information/signals on a video display unit such as a flat-screen display, a touchscreen and/or a tablet computing platform. There may be provided a video display unit adapted to receive video signals through two or more video signal paths, wherein one of the signal paths (i.e. a first signal path) may be a wired signal path. Another signal path (i.e. a second signal path) may be a wireless signal path. The display unit may be matched or paired to a matched computing platform. The paired matched computing platform may send video signals to the display unit along the wired signal path, e.g. when the display unit is docked with the matched computing platform. The paired matched computing platform may send video signals to the display unit along the wireless signal path, e.g. when the display unit is disconnected from the matched computing platform.

  • Patent number: 8559525
    Abstract: An apparatus and method for wireless transmission of uncompressed HDTV video overcomes the challenges of sending vast amounts of information over a wireless link. This is achieved by direct mapping of transformation coefficients of the video components to communication symbols, such as OFDM symbols. A main portion of the important transform coefficients, for example the MSBs of the coefficients representing lower frequencies of each of the video components, and in particular the quantized values of the lower frequencies components, are sent in a coarse representation using, for example, QPSK or QAM. The coefficients representing higher frequencies of the video components, and the quantization error values of the lower frequencies components, or some, non-linear transformation thereof, are sent as pairs of real and imaginary portions of a complex number that comprises a point in a fine constellation. The invention further provides a delay-less and buffer-less implementation of transmitter and receiver pairs.

  • Patent number: 8365238
    Abstract: The vertical blanking period is an idle period in video transmission that was originally intended for allowing the trace back of an electron beam to its point of origin. When sending the video signal over a wireless channel, the wireless channel may remain free of transmission of data during this period. However, in wireless transmission of a video signal in general, and in the transmission of an essentially uncompressed video signal in particular, there is a need to use all the bandwidth available, especially when transmitting a high-definition video signal. Therefore, a method is taught for using the vertical blanking period of a video signal for modem maintenance.
