ITU-R BS.1698 FRENCH-2005在任何频段操作的用于评估非电离辐射暴露的地面广播传输系统评估领域(问题:ITU-R 50/6)

This Recommendation is intended to provide a basis for the derivation and estimation of the values of electromagnetic radiation from a broadcasting station that occurs at particular distances from the transmitter site. Using such information, responsible organizations can then develop appropriate standards that may be used to protect humans from undesirable exposure to harmful radiation. The actual values to be applied in any regulation will naturally depend on decisions reached by responsible health agencies, domestic and worldwide.

BS EN 50083-9-2002电视和声信号用电缆分布系统.第9部分:CATV/SMATV 输入端接口和DVB/MPEG-2输送流用类似设备

1 General\nStandards of EN 50083 series deal with cable networks for television signals, sound signals and interactive services including equipment, systems and installations\n· for headend reception, processing and distribution of television and sound signals and their associated data signals and\n· for processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media.\nAll kinds of networks like\n· CATV-networks,\n· MATV-networks and SMATV-networks,\n· Individual receiving networks\nand all kinds of equipment, systems and installations installed in such networks, are within this scope.\nThe extent of this standardization work is from the antennas, special signal source inputs to the headend or other interface points to the network up to the system outlet or the terminal input, where no system outlet exists.\nThe 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.\n2 Specific scope of this part 9\nThis 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 layer format between devices of different signal processing functions.\nRF interfaces and interfaces to telecom networks are not covered in this document.\nIn addition references are made to all other parts of EN 50083 series (Cable networks for television signals, sound signals and interactive services) and in particular for RF, video and audio interfaces to part 5: \"Headend equipment\".\nFor 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 public 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 is particularly suitable for providing bandwidth on demand and it allows for high data rates.
