| Title | Domestic and similar electronic equipment interconnection requirements: AV.link - Part 2-1: Signal quality matching and automatic selection of source devices |
| Project Number | 11602 |
| Abstract/Scope | This standard specifies an extension (with the possibility to start with only two devices as a point-to-point interconnection (only a Display unit combined with a low end VTR) and than building it up) towards a chain configuration (serial interconnection of devices) with respect to the existing CENELEC standard EN 50049-1 which specifies only the characteristics of the point-to-point interconnection system for audiovisual equipment. This standard defines the interconnection characteristics of peritelevision devices which are configured in the chain principle. This standard makes use of a control signal at contact 10 which gives the possibility for automatic source de-selection and quality matching of AV-signals. This standard describes the AVC-signals in line with EN 50049-1. This standard gives system and device oriented requirements which have to be fulfilled if use is made of the logo related to this standard to ensure the customer a certain signal quality is achieved. The AV.link logo is defined in EN 50157-1. This standard gives the possibility to have a bi-directional interconnection of Y/C signals. This standard gives the possibility to have a bi-directional control of the aspect ratio of 16:9 and 4:3 |

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn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