摘要： A method for recording and reproducing video and accompanying audio information whereby various reproduction modes are made possible, including displaying a still image with appropriate sound, without adversely affecting the quality of the played-back signals. A video format signal, containing two-dimensional image information, is divided into a plurality of blocks. Audio information is inserted into predetermined ones of these blocks, and video information is inserted in the remaining blocks. The video format signal is recorded in this form on a magnetic medium. Upon reproduction, the blocks into which the audio information was inserted are, for video reproduction, either masked or replaced with other video information. Control information, including information correlating the audio and video information and, preferably, error correcting code information, is also recorded.

摘要： 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.

摘要： An apparatus for superposing a digital watermark for superposing digital watermark information on an information data signal bearing original information superposes digital watermark information on an information data signal bearing original information, for each unit block consisting of a group of pieces of information data. This apparatus is provided with an auxiliary embedding circuit 10 of or embedding second digital watermark information in the information data; a blocking circuit 12 for dividing into the unit blocks the changed information data signal obtained by the auxiliary embedding circuit; and a main embedding circuit 20 for embedding first digital watermark information in the changed information data signal for each of the divided blocks. The second digital watermark information bears information for identifying the position of the divided unit block in a predetermined section of the information data signal. On the basis of the second watermark information, a detecting apparatus effects proper blocking with respect to the information data signal with the watermark embedded therein, so as to detect the first watermark information.
