Abstract
Official abstract text for this publication.
Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I 1 , P 1 , B 1 , B 2 , B 3 , B 4 , P 2 , . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.
First claim
Opening claim text (preview).
What is claimed is: 1. A video information recording method that records video data comprising a plurality of video units each of which includes an intra coded I-picture, a predictive coded P-picture including a group of blocks predicted from one picture and a bi-directionally-predictive coded B-picture including a group of blocks predicted from two pictures, said method comprising steps of: coding at least an access point P-picture included in a group of blocks each of which is c…
