Scope

Standardisation structure of the AV.link: Within the AV.link 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
