摘要： An encryption-enabled entropy coder for a multimedia codec is disclosed. The entropy coder implements a randomized Huffman coding scheme without storing multiple sets of Huffman tables in a ROM. The entropy coder includes a ROM storing a single set of code tables, a table lookup section coupled to the ROM which converts symbols to original codewords and vice versa by performing table lookup, and a table randomizer section for converting original Huffman codewords to randomized Huffman codewords and vice versa using an isomorphic code generator algorithm. The table randomizer section performs the conversion based on a key hopping sequence generated by a pseudorandom bit generator using an encryption/decryption key.

摘要： A method and apparatus for texture image compression in a 3D video coding system are disclosed. Embodiments according to the present invention derive depth information related to a depth map associated with a texture image and then process the texture image based on the depth information derived. The invention can be applied to the encoder side as well as the decoder side. The encoding order or decoding order for the depth maps and the texture images can be based on block-wise interleaving or picture-wise interleaving. One aspect of the present invent is related to partitioning of the texture image based on depth information of the depth map. Another aspect of the present invention is related to motion vector or motion vector predictor processing based on the depth information.
