Table 35.2 Digital videotape formats for SDTV Those formats above the line are “uncompressed”<br />

(although subject to chroma subsampling); those below the line use compression. The shaded rows<br />

are consumer formats. D-4 is unused by SMPTE, owing to the number 4 being inauspicious in<br />

Asian cultures. D-8 is unused by SMPTE, to avoid potential confusion with Video-8, 8 mm, or<br />

Digital8. SMPTE has decided to leave D-13 unassigned (owing to 13 being inauspicious in Western<br />

cultures), and is likely to leave D-16 unassigned (to avoid confusion with Quantel’s D16 format for<br />

digital film).<br />

a Tape type is metal oxide, unless indicated as MP (metal particle) or ME (metal evaporated).<br />

b At its introduction, DVCPRO used 4:2:0 chroma subsampling in its 576i version, conformant<br />

with the consumer DVC standard. However, SMPTE D-7 specifies 4:1:1 chroma subsampling for<br />

both 480i and 576i at 25 Mb/s. SMPTE D-7 specifies 4:2:2 chroma subsampling for DV50.<br />
