Customer Requirements Objectives of the Consortium Members DVB and DAVIC Standards Multiservice and Multivendor Benefits Approach to Interoperability âOn 8 June 1998, Euro. Cable. Labs (ECL) - the technical research and development branch of the European Cable Communications Association - sent out an RFP to manufacturers of cable modems and interactive set top boxes.
Customer Requirements Objectives of the Consortium Members DVB and DAVIC Standards Multiservice and Multivendor Benefits Approach to Interoperability â The European cable operators. . . have, after an in-depth study of the different systems that are available, decided to choose the DVB/DAVIC system for the RFP. In their opinion this system suits the needs of the European cable operators best. The two main advantages … are the system flexibility on one hand the optimal DVB environment system design on the other hand. One single system being able to provide all services including video and audio broadcasting, data communication and telephony, represents a better solution than different, individual systems operating in parallel. This is valid both from a technical point of view as well as from an economic point of view with regard to longterm cost efficiency. â Multivendor Interoperability and Multiservice Platform is a requirement
