摘要： A digital watermark embedding device according to the present invention includes: a watermark pattern generation part (4) which generates a watermark pattern varying in a time direction based on embedding information to be embedded in an input image to be processed; a synchronization pattern generation part (3) which outputs a fixed pattern for detecting synchronization as a watermark pattern; a pattern switching part (5) which selects between the watermark pattern output by the synchronization pattern generation part (3) and the watermark pattern output by the watermark pattern generation part (4) based on the input image (7a); and an embedding processing part (6) which adds the selected watermark pattern to each pixel value of the input image (7a) to generate an embedded image (7c) having a digital watermark embedded therein.

摘要： The video and audio synchronization controller sets a system clock reference (SCR) included in the frame header portion of the coded video and audio data into a system time counter to set a timing of a system time clock (STC), immediately after a video and audio reproducing device has been powered on. The video and audio reproducing device decodes and displays a first arriving video data synchronous with a display system frame pulse, which is the closest to the value of a video time stamp included in a frame header of the first video frame on the time axis of the set STC. The video and audio synchronization controller sets again the value of the time stamp included in the first video frame to the system time counter to update the STC. The video and audio reproducing device outputs the video data for the second and subsequent video frames and all the audio data synchronous with the updated STC by outputting the video and audio data when the time indicated by the video and audio time stamps arrives on the time axis of the updated STC.

摘要： A method and apparatus for reproducing normally a picture of a recording system by operating the recording system and a display system asynchronously, and by holding and/or skipping a picture frame or field of the display system. The method for extending and reproducing compressed moving pictures includes asynchronizing data transferring a clock from a recording unit with a display system clock and then setting a hold or skip threshold which is in advance of a recording system time by a first predetermined frame (field) time. A timing is corrected by holding or skipping the display system time for one frame (field) when a display system time becomes equal to the hold or skip threshold. Frames (fields) of the display system which are closest to the recording system time are then displayed when the display system time is held or skipped for the one frame (field).
