Title Domestic and similar electronic equipment interconnection requirements: - Part 1: General
Project Number 6222
Abstract/Scope Standardisation structure of the Within the chain concept (see EN 50157-2-1) a control signal line at contact 10 of the PERITELEVISION connector is defined. Within this control signal line a bit-structure is defined introducing different modes of operation which introduces the following operation capabilities : basic capability for automatic selection of devices and automatic signal quality matching with respect to the delivered and received signals (such as e.g. R, G, B; Y/C and CVBS whereby R,G,B has the highest picture quality, Y/C is the next one and CVBS is the lowest), this part, described in EN 50157-2-1, is the base for the interconnection principle (chain concept) and is mandatory for all products implementing the parts of this standard. basic AV-system oriented commands which are meant for easy use of an AV-system with respect to the interconnection and inter-operability (EN 50157-2-2), system applications (EN 50157-2-3) future extensions

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Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn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.
