This International Standard also specifies the ar

For dated references, only the edition cited applies. For undated references, the latest edition of the refe

18、renced document (including any amendments) applies. ISO 4243, Cinematography Picture image area and photographic sound record on 16 mm motion-picture release prints Positions and dimensions 3 Positions and dimensions The positions and dimensions of the two sound records shall be as shown in Figure 1

19、 and given in Table 1. In all other respects, the sound records shall comply with ISO 4243. 4 Sound records 4.1 Channel 1 and channel 2 recording and reproducing slit images shall be positioned in line at an angle 90 5 to the reference edge of the film. 4.2 Channel 2 shall be recorded in the record

20、nearest the outer edge of the film, as shown in Figure 1. 4.3 The septum between channel records shall be effectively opaque on prints. A lighter septum resulting from direct positive recordings being printed on reversal print materials should not be cause for rejection of prints. 5 Picture-sound di

21、splacement The picture-sound displacement shall be as specified in ISO 4243. 6 Track usage The two tracks specified in this International Standard may be used for either related stereophonic material or unrelated material. When used for two-channel stereophonic program material, track 1 shall be use

22、d for the left (as viewed from the auditorium) loudspeaker channel and track 2 shall be used for the right (as viewed from the auditorium) loudspeaker channel. It is recommended that the container and leader of the print having two sound records be labelled with the above information. ISO 2016 All r

23、ights reserved 1BS ISO 7739:2016ISO 7739:2016(E) Dimensions B and C were chosen to ensure separation of channel 1 and channel 2 signals upon reproduction. Projector manufacturers will probably want to reduce the guard band between channel 1 and channel 2 scanned areas as much as possible so that the

24、 projector will be fully compatible with sound records bearing a single channel and made in accordance with ISO 4243. However, the crosstalk between them should not be less than 20 dB for stereophonic material, and not less than 26 dB for unrelated material. 1 2 3 4 5 Key 1 track 1 2 track 2 3 refer
