28、 O049430 T7b Page 6 EN 61104 : 1992 Add to subclause 17.5: ADR: 0100: ADR4. mode 4 for DATA-Q Add to subclause 17.5 (before 77.5.1): Both the lead-in track of the audio pari and the lead-in track of the video part contain the Table of Contents (TOC). The TOC contains information atjout all audio tra
29、cks (the Audio TOC) and about all video tracks (the Video TOC). See examples. If ADR = O001 (mode l), then the subcode block contains information about an audio track. If ADR = O100 (mode 4), then the subcode block contains information about a video track. (See proposed new subclause 17.5.4.) Subcod
30、e blocks with information about audio tracks and subcode blocks with information about video tracks are placed in alternating order, each block being repeated three times. The Audio TOC and the Video TOC are repeated continuously during the lead-in areas. As soon as one of these TOCS is completed, t
31、he same TOC is repeated immediately. (See also example 1 of TOC.) In the lead-in tracks mode 1 and mode 4 each occupy at least 3 out of 10 successive sub- code blocks. During the lead-in tracks POINT, PMIN, PSEC and PFRAME are defined according to 17.5.1. Furthermore: If ADR = 1 and POINT = AO the v
32、alue of PMIN gives the tracknumber of the first audio track on the disc, PSEC and PFRAME = OO. If ADR = 1 and POINT = Al the value of PMIN gives the tracknumber of the last audio track on the disc, PSEC and PFRAME = OO. If ADR = 4 and POINT = AO the value of PMIN gives the tracknumber of the first v
33、ideo track on the disc. PFRAME contains a video system identification code and PSEC = OO. If ADR = 4 and POINT = Al the value of PMIN gives the tracknumber of the last video track on the disc. PSEC and PFRAME = OO. 3404583 00474LL 702 Page 7 EN 61104 : 1992 The video identification code has the foll
34、owing meaning: 10 = NTSC “video single“ with digital stereo sound; 11 = NTSC “video single“ with digital bilingual sound; 12 = NTSC “LV disc“ with digital stereo sound; 13 = NTSC “LV disc“ with digital bilingual sound; 20 = PAL “video single“ with digital stereo sound; 21 = PAL “video single with di
35、gital bilingual sound; 22 = PAL “LV disc“ with digital stereo sound; 23 = PAL “LV disc“ with digital bilingual sound. During both lead-in tracks the other POINT codes give the starting times of the audio tracknumbers in absolute time of the audio pari and the starting times of the video tracknumbers
36、 in absolute time of the video part. The tracknumbers are: audio or video lead-in track: O0 1 01-79 audio tracknu mbers : video t racknu m be rs : audio or video lead-out track: AA Tracknumbers shall always increase by 1 from the innerside of the disc to the outerside of the disc. In the video pari,
37、 the video tracknumbers shall be the same as the chapter numbers in the 24-bit code. Chapter numbers are mandatory. The synchronization between the track- numbers and the chapter numbers shall be video frame accurate. Page 8 EN 61104 : 1992 first audio tracknumber (= m) Example 7 of TOC O0 In this e
