  • Publication number: 20110289286
    Abstract: A method, a computer readable medium and a memory controller. The method for writing information to a K-level memory unit, includes: receiving a sequence of information bits; generating an information value that represents the sequence of information bits; applying a first function to the information value, to provide a first function result; selecting a first cell of the K-level memory unit as a current cell; wherein K is a positive integer that is greater than 1; writing the first function result to the first cell; and repeating the stages of: (a) reading a current cell to provide a current read result; (b) applying a second function to the current read result and to a function result that was written to the current cell, to provide a second function result; (c) selecting another cell as a current cell; and (d) writing the second function result to the current cell.

  • Patent number: 8006168
    Abstract: Wireless transmission of high-definition video, whether essentially uncompressed or compressed, is prone to errors during reception due to the condition of the wireless link. To ensure video quality during changing link conditions it is desirable to ensure that those portions of the video that represent the more important components of the video signal, such as the lower special frequencies or most significant bits, are assured correct reception at the receiver. Bandwidth limitations of the wireless link affect the amount of data that can be sent over the link. Hence, using a high level error recovery for all of the information is not feasible. Accordingly, a method and apparatus for unequal error protection is disclosed that provides a higher level of error protection to the more important elements of the transmission while affording less error protection to the other elements of the transmission.

  • Publication number: 20110142158
    Abstract: The invention enables the transmission of continuous complex numbers using a symbol based transmission scheme such as OFDM. Accordingly, complex numbers are mapped to the constellation map, enabling a fine granularity of constellation points. This scheme may be used, for example, in the transmission of video where the coefficients representing the higher frequency of each of the video components, as well as the quantization error values of the DC and near DC components, or some, possibly non-linear transformation thereof, are sent as pairs of real and imaginary portions of a complex number that comprises a symbol.

  • Publication number: 20100014584
    Abstract: Disclosed is a method, circuit and system for transmission and reconstruction of a video block. A video stream may be composed of sequential video frames, and each video frame may be composed of one or more video blocks including a set of pixels. Prior to transmission of the data associated with a video block, the video block data may be transformed into a set of transform (e.g. frequency) coefficients using a spatial to frequency transform such as a two dimensional discrete cosine transform. Selection of the subset of transform coefficients to be transmitted may be based on a characteristic of the video block.
