scope:

Specifies an extension ((with the possibility to start with only two devices as a poin-to-point interconnection (only a Display unit combined with a low end VTR) and then building it up)) towards a chain CENELEC standard EN 50049-1 which specifies only the characteristics of the point-to-point interconnection system for audiovisual equipment. Defines the interconnection characteristics of peri-television 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 50049-1:1989/A3:1995. Gives system and device oriented requirements which have to be fulfilled if use is made of the logo related to this standard. Within this standard the AV.link logo is defined to insure towards the customer a certain signal quality. This standard defines the basics for new (socket and plug) connectors and a corresponding cord-set to be able to quarantee the signal quality. This standard quarantees a backwards compatibility towards existing equipment with the interconnection system based on EN 50049-1. 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.
