  • Systems, Methods, Devices and Arrangements for Motion-Compensated Image Processing and Coding
    Publication number: 20090034858
    Abstract: A variety of methods, devices, systems and arrangements are implemented for processing and coding of video images. According to one such implementation, a method is implemented for encoding a sequence of images. A plurality of orthogonal transforms is implemented on a set of N images, where N is greater than one. The images are linked by motion fields that include sets of respective portions of the images. In particular, the construction of a motion-compensated orthogonal transform is accomplished for the important case where at least one portion of any of the N images—or any part of this portion—is used more than once to motion-compensate other portions of the N images—or parts thereof.

  • Video communications in a peer-to-peer network
    Patent number: 7969997
    Abstract: Packet-based delivery of video content is facilitated using a peer-to-peer network. According to an example embodiment of the present invention, a packet-based video stream is passed over a peer-to-peer network, with the packets in the stream scheduled and delivered in accordance with a priority assigned to the packets; this priority is based upon a determined or estimated effect that the packet will have upon video quality at a recipient peer. In some applications, the packets are temporally spaced to mitigate congestion and/or distortion of video associated with congestion in the delivery of the packets.

  • Image signal coder operating at reduced spatial resolution
    Patent number: 5917954
    Abstract: An image processing system operates at reduced resolution to reduce computational complexity while remaining fully compatible with full resolution decoders. A video input signal is subsampled and encoded at the resulting lower resolution. The encoded signal is filled with zero terms to produce an encoded signal having the same number of terms as a full resolution encoded signal. In a motion-compensated hybrid coder, the decoder section also includes a subsampling system, so that the reconstructed video signal is produced at the same resulting lower resolution. The encoder section and the decoder section are each inverse functions of the other, eliminating a drift problem associated with prior systems.

  • Data communication arrangement having variable length coding and method therefor
    Patent number: 6211801
    Abstract: A variable length coding system encodes and decodes symbols as uniquely decodable code words using an assignment scheme having a maximum code word length. According to one embodiment, a first bitstream is combined with a second bitstream to provide a resultant bitstream to be sent over a communications channel. The first bitstream represents the code words in a forward direction, and the second bitstream contains the same code words reversed and bit delayed by at least the maximum code word length. A resultant bitstream can be decoded in forward or reverse direction. The scheme is highly efficient for long blocks of data and the reversible aspect of the coding scheme improves the tolerance for errors caused by channel interference.
