OTHER DVC SYSTEMS
There are four primary standards in the DVC format. ATV, for use with the US Advanced TV System, offers high-definition digital TV, while DVB is for use with the sort of digital broadcast system described in Chapter 12 of this book. SD has been the subject of this chapter; its specification was given in Table 19.3. HD is the high- definition variant for which the specification is given in Table 19.4.
The main differences between HD and SD variants is the tape speed, twice as fast giving half the running time; the four-head drum; and a picture resolution capability approaching 1500 lines.
