This part of IEC 61834 is an extension to the SD specification (SD mode) and covers the features necessary for the recording and reproduction of EDTV2 signals. While all DVCRs must have the capability of recording and/or playback in SD (SP) mode, this extension is optional. For this part 7, the data track structure of a track is defined by APT = 000b which consists of four areas as described in 4.3.2 of IEC 61834-1, and AP1 = AP2 = AP3 = 000b. NOTE EDTV2 signal format is described in the specification: BTA T-1004-1995: Video signal interfaces for EDTV2 studio equipment.
