Abstract
A method and an apparatus for designing a codebook error resilient data transmission is disclosed. The present invention allows for creation of a robust yet compressive codebook for transmission of data. One embodiment of the present invention utilizes a combination of Huffman and Gray coding techniques to achieve both robustness and high compression ratios for data sets of single or multiple dimension. In particular, the present invention utilizes a series of Gray codes to improve the robustness of a Huffman code utilized by the MPEG-4 standard for motion video compression. The present invention may also be used to create codebooks for other forms of data, these codebooks can be designed to be robust or robust and compressive, and can encode data of single or multi-dimensional format.
