Add to clause 10 the following subclauses: 10.5 Signals in the video part The signals in the video part are defined in Sections3 and4 of IEC856 and IEC857 for PAL and NTSC respectively. The following modifications in these standards are appl
33、icable: 10.5.1 Analog audio (clauses 7 and 8 of section3) The analog audio carriers are removed completely. 10.5.2 Digital audio or data 10.5.2.1 Digital audio or data shall be added according to IEC857, second edition (under consideration), for NTSC and IEC856, second edition (under consideration)

35、ignal (clause10 of section3 of IEC857, NTSC only) The40-bit code shall not be used. Add to subclause 17.5: ADR:0100:ADR4, mode4 for DATA-Q Add to subclause 17.5 (before 17.5.1): Both the lead-in track of the audio part and the lead-in track of the video part contain the Table of Contents(TOC). The T
36、OC contains information about all audio tracks (the Audio TOC) and about all video tracks (theVideoTOC). See examples. If ADR=0001 (mode1), then the subcode block contains information about an audio track. If ADR=0100 (mode4), then the subcode block contains information about a video track. (Seeprop
37、osednew subclause17.5.4.) Subcode 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 o
38、ne of these TOCs is completed, the same TOC is repeated immediately. (See also example1 ofTOC.) In the lead-in tracks mode1 and mode4 each occupy at least3 out of10 successive subcode blocks.

39、-2000 During the lead-in tracks POINT, PMIN, PSEC and PFRAME are defined according to17.5.1. Furthermore: If ADR=1 and POINT=A0 the value of PMIN gives the tracknumber of the first audio track on the disc, PSEC and PFRAME=00. If ADR=1 and POINT=A1 the value of PMIN gives the tracknumber of the last
40、audio track on the disc, PSEC and PFRAME=00. If ADR=4 and POINT=A0 the value of PMIN gives the tracknumber of the first video track on the disc. PFRAME contains a video system identification code and PSEC=00. If ADR=4 and POINT=A1 the value of PMIN gives the tracknumber of the last video track on th
41、e disc, PSEC and PFRAME=00. The video identification code has the following 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 singl
42、e” with digital stereo sound; 21=PAL “video single” with digital 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 audi
43、o part and the starting times of the video tracknumbers in absolute time of the video part. Tracknumbers shall always increase by1 from the innerside of the disc to the outerside of the disc. In the video part, the video tracknumbers shall be the same as the chapter numbers in the24-bit code. Chapte
44、r numbers are mandatory. The synchronization between the tracknumbers and the chapter numbers shall be video frame accurate. The tracknumbers are: audio or video lead-in track: 00 audio tracknumbers: 0179 video tracknumbers: audio or video lead-out track: AA EN61104:1992 BSI 01-2000 7 Example1 of TO
45、C In this example the general outline of the TOC is described. * Each subcode block is repeated three times.EN61104:1992 8 BSI 01-2000 Example2 of TOC In this example the way of asynchronous mixing of Audio TOC and Video TOC is described in the case of two audio tracks and one video track. Only ADR
46、and POINT are mentioned in the example. Add new subclause: 17.5.4 Mode4 for DATA-Q ADR=4=(0100) Mode4 occupies at least9 out of10 successive subcoding blocks. Mode4 has the same structure as mode1, so the tracknumber indexnumber and the absolute and relative time codes are defined according to the d
47、escription in17.5.1. In the video area, the absolute time is restarted at zero.
