Recording medium, reproducing apparatus, and reproducing method |
摘要 |
In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed. |

1. A non-transitory medium containing a video information stream, said video information stream comprising a plurality of video information units each of which includes an intra coded I-picture, a predictive coded P-picture and bidirectionally-predictive coded B-picture,
said video information stream including a first video information stream representing a primary video sequence, a second video information stream representing secondary video sequence which is presented with said primary video sequence and an access point map which includes access point information and I-picture size information of said first video information stream and said second video information stream, wherein a playback device identifies a closest one of I-pictures preceding a start picture corresponding to a start point of playback for said first video information stream and a second video information stream and locates a position of identified I-picture for said first video information stream and said second video information stream by referring to said access point map, and a displayed video picture corresponding to said second video information stream is superimposed on the lower part of a displayed video picture corresponding to said first video information stream. |
