Abstract: A watermark information embedding method, and apparatus, capable of suppressing the quality degradation of contents and increasing the survivability of embedded information. When embedding watermark information in moving picture data formed of a plurality of still picture frames arranged in time series, a motion vector representing a property specific to moving picture is detected for each of image blocks generated by dividing a target frame. According to a motion quantity, a pixel change factor specifying rule is selected for each block. Out of pixels permitted to be changed in luminance depending upon the state of an image in each block representing a property specific to still picture, as many pixels as a number specified by the selected rule are selected. Luminance change processing for forming watermark information is conducted on the selected pixels.

Abstract: A system comprising a recording apparatus for recording record information onto a recording medium and a reproducing apparatus for reading the record information from the recording medium and outputting it to reproduce, is provided. The record information includes: image information; a first identification information which represents any one of never copy, one copy and copy free; and a second identification information which represents either the never copy or the one copy. The never copy indicates copying is prohibited. The one copy indicates copying is once permitted. The copy free indicates copying is permitted. The recording apparatus controls recording the record information, and determines whether or not the record information is to be encrypted based upon the first identification information and the second identification information.

Abstract: An optical recording medium comprises a first information recording surface; a first reflecting layer formed on the first information recording surface; a second information recording surface; and a second reflecting layer formed on the second information recording surface. In particular, the first reflecting layer contains a titan oxide as a main component.

Abstract: A frame of a video signal is divided into a plurality of sub-frames. Each of the sub-frames is composed by an address period for selecting light emitting pixels or light non-emitting pixels at every scanning line in accordance with a pixel data, and a discharge sustaining period for causing a light emitting pixel to emit at a number of times in accordance with weighting of each sub-frame. A plurality of sub-frames are adjacently disposed to form a sub-frame block. A reset period is provided in a first sub-frame of the sub-frame block so as to initialize all pixels prior to the address period.
