    • Apparatus and methods are disclosed for providing an improved system for identifying the location and value of errors introduced in binary data encoded using Reed-Solomon and related codes and to detect miscorrections of such codes with an auxiliary code. The invention employs an architecture based on a microcode engine that is specialized for error identification and that supports interleaved codewords. This architecture can be efficiently fabricated as an integrated circuit, yet is capable of identifying multiple introduced errors "on the fly" i.e. with performance sufficient to not significantly slow the process of reading from data storage or transmission subsystems such as, but not limited to, optical disks. In the preferred embodiment, a new two-step method of error syndrome computation is employed to reduce circuit cost and complexity. An improved iterative algorithm is provided which reduces circuit cost and complexity and decreases the time required to generate the error locator polynomial. Cyclic redundancy check (CRC) information is adjusted as introduced errors are identified during the Chien search, thus reducing the time required to protect against ECC miscorrection. Externally-specified error thresholds allow detection of excessive numbers of errors.
    • 公开了用于提供改进的系统的装置和方法,该系统用于识别使用Reed-Solomon和相关代码编码的二进制数据中引入的误差的位置和值,并且用辅助码来检测这些代码的误差。 本发明采用基于专用于错误识别并支持交错码字的微代码引擎的架构。 该架构可以有效地制造为集成电路,但是能够“即时”地识别多个引入的错误,即具有足以不显着地减慢从数据存储或传输子系统读取的过程的性能,例如但不限于, 光盘。 在优选实施例中,采用新的误差校正计算的两步法来降低电路成本和复杂度。 提供了一种改进的迭代算法,其降低了电路成本和复杂性,并减少了生成误差定位多项式所需的时间。 循环冗余校验(CRC)信息被调整,因为在Chien搜索期间识别出引入的错误,从而减少了防止ECC错误修复所需的时间。 外部指定的错误阈值允许检测到过多的错误。

    • Methods and apparatus for reducing the bandwidth required to transmit analog information. The analog information is converted to digital data organized in time defined blocks of information called frames. The content of a frame may be modeled as a composite of superimposed objects, which are subsets of information in the frame, that are largely unchanged frame to frame. Each object in a present frame may be represented by an identification of the object and a description of the charges in object-to-frame relationship that occurred from a previous frame to the present frame. The objects in the present frame may then be reconstructed by adjusting the objects in the previous frame in accordance with the change in object-to-frame relationships.
