As previously mentioned in the general description, interworking units will have to be provided, but only in TESUS 2, to allow interoperability between broadband and narrowband videonetworks. The aim of the project is to circumvent the degradation of the video quality imposed by the bridging between different protocols and to offer to all users high quality transmission networks in the last phase of the project. As far as databases are concerned, interoperability will be guaranteed by use of standards like MPEG 1, MPEG 2 and MH EG.
