    摘要: In an optical disk, a number of video object units arranged consecutively are recorded. The video object unit contains a navigation pack and video packs following the navigation pack, the navigation pack having address information and a picture category relating to a reference picture, the picture category being determined in compliance with the importance level in respect to the reference picture. A sequence of the packets constitutes a stream of nal units classified into a first group of the nal units contributing to produce the reference picture and a second group of the nil unit not contributing to produce the reference picture. In a nal header of the nal unit, reference item information is described that the nal unit belongs to the first group and contributes to produce the reference picture and a type of the payload, the reference item information indicates the priority of the nal unit.

    摘要: In generation of a system header included in an program stream of extended MPEG-2 Systems, when a basic stream ID is an extension ID and basic buffer size information represents 0 byte, extension buffer size information expressed by a total of 24 bits of an extension ID, a marker bit and an extension stream ID and a total of 24 bits including an extension stream ID, a marker bit and extension buffer bound scale information and required for reproduction of an elementary stream to be multiplexed using a pair of an extension ID and an extension stream ID is generated and recorded.

    摘要: A specific frequency component extraction unit extracts a specific frequency component signal from an input image signal. A phase controller controls the phase of the specific frequency component signal. A correlator computes the cross-correlation value of the phase-controlled specific frequency component signal and the input image signal. A watermark information estimation unit filters the cross-correlation value to detect watermark information embedded in the input image signal.
