[Means for solving problems]
The information recording medium according to the present invention has a data area in which video data divided into a plurality of video object units, each of which is composed of a plurality of cells that can be reproduced and managed by program chain information, is recorded, and is recorded in this data area. In a recordable / reproducible information recording medium having a management area for recording management data including video object information for managing the recorded video data in units of video objects, the video object information recorded in the management area is included. Image quality information is included.
また、この発明に係る記録再生装置は、映像データが記録されるデータ領域と、このデータ領域に記録された映像データを管理するための管理データが記録される管理領域とを有する、記録再生可能な情報記録媒体に対して記録再生を行なうもので；データ領域の残り記録容量に基づいて、記録する映像データの画質を決定する画質決定手段と；この画質決定手段で決定された画質に基づいて、管理領域に記録する画質情報を設定する画質情報設定手段と；この画質情報設定手段で設定された画質情報を管理領域に記録するとともに、管理領域に記録された画質情報を再生する制御手段とを備えるようにしたものである。 Further, the recording / reproducing device according to the present invention has a data area in which video data is recorded and a management area in which management data for managing the video data recorded in this data area is recorded. Recording and playback are performed on various information recording media; an image quality determining means for determining the image quality of the video data to be recorded based on the remaining recording capacity of the data area; and an image quality determining means based on the image quality determined by the image quality determining means. , An image quality information setting means for setting the image quality information to be recorded in the management area; and a control means for recording the image quality information set by the image quality information setting means in the management area and reproducing the image quality information recorded in the management area. It is designed to be equipped with.
