| Title | Measuring method for chrominance signal-to-random noise ratio for video tape recorders |
| Project Number | 4011 |
| Abstract/Scope | Describes a technique for measuring the impairment of a TV picture due to random noise in a colour signal. The values which result from this measurement method make it possible to compare different video tape records, recording systems and video tapes for their random noise characteristics. Is intended for use with all IEC recognized video recording formats. |

| Normative reference (6) |
(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
