    摘要: The present invention provides an electronic watermark editor for a compressed video that can efficiently carry out editing such as deletion or rewriting of electronic watermark data.DCT coefficient values are extracted while applying all templates to video contents, and a template where a total sum of relative absolute value differences between pairs of the DCT coefficient values is maximized is judged to be an applied template. The pairs of DCT coefficient values extracted by the applied template are processed by a smoothing process section so that the relative differences are reduced and so as to reduce individual relative differences recursively until significant differences between the coefficient value pairs are statistically eliminated. In addition, the pairs of DCT coefficient values extracted by the applied template are replaced with new editing bits.

    摘要: This invention aims to form hierarchies of coded moving picture data in a simple method or apparatus. An I, P and B separator separates I, P and B picture data from coded moving picture data. A first to a third header/low/high separator separate headers and low and high DCT data components of the separated I, P and B picture data, and hierarchy forming means assigns the outputs of the separators for a 1-st to a 6-th hierarchy by supplying the outputs to packetizers therefor. The packetizers packetize the assigned data, and send out the packetized data on communication lines for the 1-st to 6-th hierarchies. For example, low frequency components of I picture data are provided as the 1-st hierarchy, high frequency components of I picture data are provided to the 2-nd hierarchy, low frequency components of P picture data are provided as the 3-rd hierarchy, high frequency components of P picture data are provided as the 4-th hierarchy, low frequency components of B picture data are provided as the 5-th hierarchy, and high frequency components of P picture data are provided as the 6-th hierarchy.

    摘要: A second tally image generating means 20 that outputs a pixel value B1m,n of a second tally image B1 includes a decoding-time peripheral luminance value calculating section composed of a decoded pixel value calculating means 28 and a peripheral luminance value calculating means 29.
