[0080] figure 1 The signal recording format of DVD-Video (Digital Video Disc-Video) is shown. As shown in 1, the video DVD has a first area allocated to the video manager VMG. Following the VMG area are sequences assigned to the second and subsequent areas of the video production set VTS, respectively.
[0081] Each VTS area has a series of areas, namely one area allocated to VTS information VTSI, one or more areas allocated to respective sets of video content blocks VCBS, and one area allocated to VTS information VTSI. The first video content block set VCBS stores menu information indicating menu screens.
[0082] Each VCBS region has a series of regions respectively assigned to video content blocks VCB. Each video content block VCB corresponds to a video work.
[0083] Each VCB area has a series of areas respectively corresponding to chapters. Each chapter contains information representing a part of a work marked by PTT.
[0084] Each chapter has a series of units. Ea...

[0151] Figure 26 An audio DVD (Audio Digital Video Disc) signal recording format according to a second embodiment of the present invention is shown. Figure 26 The audio DVD in has an area allocated to the audio set directory ATS_D containing several audio set sets ATS. Figure 26 The audio DVD in does not have any area allocated to the video collection VTS.
[0152] The ATS_D area has an area allocated to the audio manager AMG, an area allocated to the audio manager menu AMGM, an area allocated to the first audio composition set ATS, and an area allocated to the second audio composition set ATS a region of the . The audio manager AMG contains audio manager information AMGI for managing audio work sets ATS and ATS. Audio Manager AMG has something like image 3 in that structure.
[0153] Audio Work Collections ATS and ATS are similar in structure. Therefore, only the audio composition set ATS will be described below.
[0154] Such as Figure 27 As shown, the audio work...

[0183] Figure 36 An audio signal encoding device according to a third embodiment of the present invention is shown. Figure 36 The device includes analog-to-digital (A / D) converters 31 and 31V, a signal processing circuit 32, a video encoder 32V, and a DVD formatting section 34.
[0184] The analog video signal is applied to the A / D converter 31V. A / D converter 31V followed by video encoder 32V. A video encoder 32V is followed by a DVD formatting section 34 .
[0185] The analog audio signal is applied to the A / D converter 31 . In general, an analog audio signal has multiple channels, eg including front and rear channels. Analog audio signals may be of the monaural type. The A / D converter 31 is followed by a signal processing circuit 32 . The signal processing circuit 32 is followed by a DVD formatting section 34 .
[0186] The DVD formatting section 34 is sequentially followed by a modulation circuit 35A and a master authoring device 35B.
[0187] Such as Figure 37...
