32、reception, processing and distribution of television and sound signals and their associated data signals and for processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media. All kinds of networks like CATV-networks, MATV-networks and
33、 SMATV-networks, Individual receiving networks and all kinds of equipment, systems and installations installed in such networks, are within this scope. The extent of this standardization work is from the antennas, special signal source inputs to the headend or other interface points to the network u
34、p to the system outlet or the terminal input, where no system outlet exists. The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well as of any coaxial and optical cables and accessories therefor is excluded. 1.2 Specific scope of this part 9 Th
35、is standard describes physical interfaces for the interconnection of signal processing devices for professional CATV/SMATV headend equipment or for similar systems, such as in uplink stations. Especially this document specifies the transfer of DVB/MPEG-2 data signals in the standardized transport la
36、yer format between devices of different signal processing functions. RF interfaces and interfaces to telecom networks are not covered in this document. In addition references are made to all other parts of EN 50083 series (Cable networks for television signals, sound signals and interactive services
37、) and in particular for RF, video and audio interfaces to part 5: “Headend equipment“. For connections to telecom networks a special Data Communication Equipment (DCE) is necessary to adapt the serial or parallel interfaces specified in this document to the bitrates and transmission formats of the p
38、ublic Plesiochronic Digital Hierarchy (PDH) networks. Other emerging technologies such as Connectionless Broadband Data Services (CBDS), Synchronous Digital Hierarchy (SDH), Asynchronous Transfer Mode (ATM) etc. can be used for transmitting MPEG-2 Transport Streams (TS) between remote locations. ATM
39、 is particularly suitable for providing bandwidth on demand and it allows for high data rates.
