  • Patent number: 6560280
    Abstract: In a video system incoming video having a given frame size is sent over a video transmission system that supports a different frame size. When a transmitting terminal in the transmission system receives the incoming video, the terminal does not scale the video to fit the transmitted frame size. Instead, the video compression encoder only encodes and sends the data associated with the incoming video. The encoder does not encode or send the rest of the standard transmitted frame. At a receiving terminal in the transmission system, all of the received data is decoded. However, because the decoded data will correspond to the original incoming frame size, this data, rather than the entire transmitted frame, is scaled to match the size of the display or the target window.

  • Patent number: 6285404
    Abstract: A systolic video encoding system processes image data from a frame buffer at a core clock rate that is independent of the sample rate of the image data. The video encoder of this invention uses the core clock rate of the host image processing system to process image from the frame buffer at this core clock rate. The image data is pumped out of the frame buffer, processed by each of the processes of the video encoder when the data reaches each of the processes, and the encoded samples are stored in a raster sample buffer for subsequent processing. The image data is continually pumped out of the frame buffer at the core clock rate until the raster sample buffer is full. As the samples are extracted from the raster sample buffer, subsequent image data is pumped into the video encoding system, producing a systolic processing effect.

  • Patent number: 6037991
    Abstract: A communication system (100) employs a method and apparatus for communicating video information therein. A first communication device (e.g., 101) preferably includes a video compressor (203), a memory device (205) containing a computer program, and a modem (207). The first device receives video information from a video device (116) via the video compressor and executes the computer program to determine a priority between transmission frame rate and resolution per frame. When transmission frame rate is of higher priority, the first device transmits the video information at a first transmission frame rate via the modem to a second communication device (e.g., 102). When resolution per frame is of higher priority, the first device transmits the video information at a second transmission frame rate that is less than the first rate. The second device, upon receiving the video information, may display (113) the information or process the information for retransmission (e.g.

  • Patent number: 6014175
    Abstract: For preparation of sampled values represented as two's complements, a two's complement clipping of the least significant bits(LSB) occurs. In place of the removed bits (LSB), the synchronization information (s(k)) is added with an average value depending on the quantization step. No dominant spectral lines for frequencies f greater than zero are permitted to occur in the useful spectrum for this synchronization information. Errors which are caused by removal of the least significant bits and by addition of the synchronization information are largely compensated by these features.

  • Patent number: 6008857
    Abstract: Digital data comprised of bytes formed of a predetermined number of data bits are encoded for representation in a video frame. Each byte of digital data, or a portion thereof, is represented in a respective region of the video frame by one or more video component levels that are assigned to the region and which correspond to the numerical value of the data bits of the byte or of the portion. The digital data are represented in the video frames in place of a video image or, alternatively, are represented in the same frames in which video images are recorded but in the areas of the frame in which the video image is not ordinarily recorded. Digital data represented in the video frame are decoded from the video component levels assigned to the regions.

  • Patent number: 5995147
    Abstract: A receiving process is realized with a simple configuration when a plurality of sources such as in the television broadcasting or the like are transmitted efficiently at the same time. A plurality of transmission bands are prepared each including a predetermined number of subcarriers arranged at a predetermined frequency interval. The signal of each transmission band is delimited at a predetermined time interval to form a time slot. For transmitting a plurality of data A to P, after individual data are transmitted during a predetermined time slot period using a predetermined transmission band, the transmission band is switched to the separate transmission band and the particular individual data is transmitted during a predetermined time slot period. The receiving band is switched at the receiving side in an interlinked relation with the switching of the transmission band for transmitting the desired data.

  • Patent number: 5987543
    Abstract: Video data is communicated in a computer system using LVDS signaling. To maintain minimum setup time requirements, video data is translated to LVDS data streams using a TTL-to-LVDS converter (84) which clocks data at the rising edge of a pixel clock signal and is re-converted using an LVDS-to-TTL converter (86) which uses the falling edge of the pixel clock to clock data for output.

  • Patent number: 5940135
    Abstract: Apparatus and methods are provided for encoding, storing and decoding auxiliary information on an analog source signal in a way which has minimal impact on the human perception of the source information when the source signal is applied to an appropriate output device, such as a speaker or a display monitor. The autocorrelation function of a host signal is modulated according to the value of an auxiliary information signal by adding a host modifying signal to the host signal. The auxiliary signal is decoded by generating the autocorrelation function of the encoded signal and extracting the auxiliary signal according to well-known signal extraction techniques.

  • Patent number: 5850264
    Abstract: Sequential digital video frames are divided into two interleaved fields comprising even-numbered horizontal lines of pixels and odd-numbered lines horizontal lines of pixels respectively. The "even" field of a first standard frame is combined with the "odd" field of a second standard frame to form a first pseudo-interlaced frame of data for display; then the same odd field is combined with the even field of a third standard frame to form a second pseudo-interlaced frame of data for display, and so on throughout a continuing digital-video message. The data transmission rate needed is thus reduced by nearly a factor of two, or conversely, for a given data rate, nearly twice as much video information can be transmitted in the same time interval.
