摘要： A method and apparatus for encrypting and decrypting digital data employing multiple Huffman tables and at least one encryption key to enhance security of the digital data. At least one image parameter for characterizing the digital data, such as a motion vector table or DC-luminance, is selected as an image parameter. All possible Huffman tables according to the image parameter are then generated by Huffman tree mutation. A predetermined number of active Huffman tables from all possible Huffman tables are selected using a first encryption key and a hash function. Afterward, a coding sequence for the active Huffman tables is generated using a second encryption key and the hash function. Finally, the digital data is encrypted into an encrypted bit stream by the active Huffman tables with the coding sequence. Encrypted symbols of the image parameter can be reduced by symbol statistic analysis, thus reducing computation effort.

摘要： Simple, computational efficient, and robust audio features are applied in a uniform program indexing method for picking up video segments relating to highlight plays in a recorded program worthy of being reviewed. By focusing on certain frequencies in an audio sequence of the program, a computational complexity of the uniform program indexing method is significantly decreased. With the aid of MFCC coefficients and a DFBE coefficient generated from the MFCC coefficients, audio patterns may be utilized for differentiating exciting events in the program from other unnecessary information. Scores corresponding to various audio segments are regarded as standards for picking up video segments in the program worthy of being chosen in a recorded highlight collection. Some low-level-feature parameters, some video segments having highlight-related visual characteristics, and a re-ranking procedure are utilized for enhancing precision of the scores for providing video segments worthy of being reviewed.
