Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0042] In the present invention, the relationship between the data readout rate (reproduction rate) Vr of the recording medium and the user data rate Vo is particularly important. Thus, techniques constituting the assumption of the present invention will be described.

[0043] FIG. 1 is a schematic structural diagram of a module for realizing image signal compression processing. For an image signal, the motion vector of the portion to be coded is estimated by motion compensation prediction processing. Inter prediction that compensates for the amount of motion is realized in the motion compensation prediction processing section 11 . Next, the predicted data is subjected to two-dimensional discrete cosine transform (DCT) processing in the DCT section 12 . In this process, redundancy is compressed. In order to transmit compressed data via a digital circuit, it is neces...

Abstract

An information recording medium in which recording information including video information is coded at a variable transfer.rate and is recorded as coded information. The coded information is read and decoded in accordance with a decoding process to decoded the video information. A variable transfer rate (Vo) of the coded information is set with respect to a reproducing rate (Vr) in such a manner that an average rate (Voa) of (Vo) for each specific interval is smaller than that the reproducing rate (Vr), and a value of (Vo) larger than that of the reproducing rate (Vr) is permitted for a peak rate (Vop).

Description

technical field [0001] The present invention relates to an information encoding method, a recording method, a recording medium, a recording apparatus, and a restoration apparatus effective for recording images, sounds, sub-images, etc. in a recording medium such as an optical disc. In particular, fields where the present invention is effectively applied include encoding methods for realizing high image or sound quality, and techniques for realizing high image or sound quality means in seamless restoration processing of multiple scenes. Background technique [0002] In recent years, an optical disc in which images, sounds, sub-pictures, etc. are encoded and the encoded data is recorded in high density and a restoration device for the optical disc have been developed. When recording information such as a movie on an optical disc, there is a method of fixing the encoding transfer rate, and a method of using a variable rate. The fixed rate system is adopted as an information re...
