When the user enters a command to eject an optical disc from an optical-disc apparatus by operating an input unit, a CPU records information such as an operating mode and a location accessed immediately prior to ejection of the disc into a RAM unit as resume-function related information. The resume-function related information is then supplied to the optical disc to be recorded thereon by way of a write-in channel buffer, a switch, an ECC circuit, an RF & demodulation/modulation circuit and an optical head. Accordingly it is possible to make an access to a location on an optical disc accessed immediately prior to ejection of the disc from an optical-disc apparatus when the disc is reinserted into the optical-disc apparatus.

It is possible to display a caption with an aspect ratio independent from the aspect ratio of a main video. When a flag indicating that the aspect ratio of the caption is 16:9 is set, the caption video image frame size (720×480) is converted so as to match the aspect ratio of 16:9 and the caption video obtained as the result is superimposed on the main video and displayed. That is, when the main video has an aspect ratio of 4:3, as shown in FIG. 19, reduction in the lateral direction is performed and the main video is displayed with addition of black tone at the right and left but the caption video is displayed with the aspect ratio of 16:9.

A recording and reproducing apparatus for recording a program including video and/or audio information on a removable recording medium includes an interface, a recording unit, a reproducing unit, and a controller. The interface is configured to receive reservation information for recording the selected program. The reservation information includes maximum bit rate information. The recording unit is configured to record the reservation information on the removable recording medium. The reproducing unit is configured to reproduce the reservation in formation from the recording medium when the removable recording medium is loaded. The controller is configured to record the selected program on the removable recording medium based on the reservation information.

With append_only_flag reset to 0, data is recorded over existing data on a disc in accordance with the value of volume_write_protect_level. With append_only_flag set to 1, on the other hand, data can not be recorded over existing data on the disc but can be appended to already recorded data in a range defined by the value of volume_write_protect_level. As a result, it is possible to prevent new data from being written over already recorded data by mistake and to utilize the recording area of the disc efficiently.

This invention provides a recording apparatus, a recording method, a playback apparatus, a playback method, a recording/playback apparatus, a recording/playback method, a recording medium and a presentation medium. In this invention, information on the album is recorded only into a chief disc, one of the discs composing the album. The other discs simply include an identification of the chief disc. Accordingly it is possible to allow a plurality of recording media to be handled as a unit with ease and to allow each of the recording media to pertain to a plurality of such units.

A characteristic point detection circuit detects a characteristic point from a base band video signal and generates a characteristic point file. A compressed video signal received from the digital satellite broadcast is supplied to a multiplexing circuit as it is in the form of a bit stream. The multiplexing circuit multiplexes the compressed video signal and characteristic point file. A control circuit obtains the characteristic point file from an optical disc during reproduction, and controls reproduction of the compressed video signal. As described herein above, the supplied compressed video signal is recorded in a recording medium without deterioration of the image quality, and the recorded video signal accepts random access.

At step S372, permission information about video data that are being reproduced is obtained from permission information that represents whether video data corresponding to encoded video data equal to or larger than an access unit are permitted to be secondarily used. At step S373, it is determined whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information. When it has been determined that the video data that are being reproduced have been permitted to be secondarily used, at step S376, the video data that are being reproduced are captured. At step S381, a process using the captured video data is executed. The present invention can be applied to for example a game device that uses a DVD.
