摘要： An encoding apparatus includes a first encoding unit adapted to encode inputted data, an interleaving unit adapted to interleave the inputted data, and a second encoding unit adapted to encode an output of the interleaving unit. The encoding apparatus executes a first encoding algorithm using the first encoding unit, and executes a second encoding algorithm using the first encoding unit, the interleaving unit and the second encoding unit. Furthermore, the encoding apparatus shares the first encoding unit when the encoding apparatus executes the first and second encoding algorithms in parallel.

摘要： Copyright information embedded in a digital content can always be sampled and the copyright of the digital content can be protected reliably, by using a sampling program which is automatically activated and samples the copyright information from the digital content. For example, the digital content added with the sampling program is distributed or an application program added with the sampling program for utilizing the digital content is distributed so that the copyright information can be reliably sampled from the digital content and the utilization of the digital content can be controlled in accordance with the copyright information. If a file containing a plurality of digital contents is used, copyright information is embedded in each digital content and the copyright information is sampled from each digital content. It is possible to control the utilization of each digital content in accordance with the sampled copyright information.

摘要： Provided are an information processing apparatus, method, program and storage medium whereby prescribed additional information such as a digital watermark can be embedded directly in encoded data, and later extracted, without decoding data that has been compressed and encoded by the JPEG scheme, etc. First, encoded data, which is information that has been encoded, is input from an encoded data input unit (101). An embed coefficient is selected in an embed coefficient selector (102) block by prescribed block, and a code transformation unit (103) replaces the encoded data by different encoded data, which corresponds to the input encoded data, input using a transformation table (104), whereby a digital watermark is embedded.
