19、1 Scope This part of IEC 62330 defines the data stream used for synchronous transmission of HD-D5 compressed video and audio data over 360 Mb/s serial digital interface (SDI) for the 525/60 system as defined in SMPTE 259M.

26、SI/SMPTE 259M. One 1 080i field or one 720p frame of 5 760 DIF blocks, containing 489 600 words, are mapped into a rectangular area of 1 920 word columns (from sample number 0 to 1 919 horizontally) by 255 word rows (from line number 9 to 263 in the first field or from line number 271 to 525 in the

27、second field vertically) on SDI. In the case of 1 080i, DIF blocks of the 1st field compressed video data shall be mapped into the first field of SDI and DIF Blocks of the second field compressed video data shall be mapped into the second field of SDI respectively. One field contains 480 slice cells

28、. One slice cell is composed of 4 word columns by 255 word rows. The slice cell structure over SDI is shown in Figure 3. Each DIF slice (see Figure 2) is allocated into each slice cell according to the following expression: CN = (SN 4) mod 480 + int (SN / 120) where SN: DIF slice number CN: Slice ce

29、ll number Each slice cell is divided into 12 DIF areas. The DIF area, consisting of 85 words, has four different area configurations; i.e. type A through D as shown in Figure 4. Each DIF area is identified by a DIF area number (AN). The DIF block number (BN), DIF area number (AN), and slice cell num
