The reference document was approved by CENELEC as EN 60933-5 on 9 March 1993. The following dates were fixed: For products which have complied with the relevant national standard before 1994-03-01, as shown by the manufacturer or by a certification body, this previous standard may continue to apply for production until 1999-03-01. latest date of publication of an identical national standard(dop) 1994-03-01 latest date of withdrawal of conflicting national standards(dow) 1994-03-01 Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 11 09:09:07 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 60933-5:1993 © BSI 12-19993 1 Scope This International Standard applies to the transfer of video signals between two pieces of equipment in an NTSC, PAL or SECAM high-resolution colour video system, in the form of a Y-signal, consisting of luminance + blanking + sync, and a C-signal, the same as the modulated chrominance signal of the composite video signal. It specifies the signal levels and impedances at the interface and the type of connector to be used. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitutes provisions of this International Standard.

NOTE 2For PAL a) The time coincidence of the Y and C signals shall be measured using a standard colour bar signal at the transition of green and magenta, where the C signal makes a zero crossing. See Figure 2. b) The C signal shall be time coincident with the Y signal within 100 ns. This shall be measured at the output of the source equipment. c) The amplitude of the green and magenta chroma signals shall be equal within 10 %.
