After work with the European Broad-casting Union, the Society of Motion Picture and Television Engineers has ratified JVC's Digital-S as the D9 format. So what are D s 1 to 8, and will there be a D10? Here s a crib sheet. In 1986, SMPTE adopted Sony's standard for full-frame 8-bit digital recording with 19mm/0.75" cassettes, as Dl. It used CCIR Recommendation 601 for 4:2:2 component coding. The luminance information is sampled at 13.5MHz and the two colour difference signals at 6.75MHz. The BBC ganged two Dls together to record HDTV.
