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
