BS EN 62216-1:2002 DVB-T系统用数字化地面电视接收器.基线接收器规范

This part of IEC 62216 specifies the baseline receiver for the DVB-T system. It concerns: ? broadcasters, and ? receiver manufacturers. The objective is to define: ? how to provide broadcasts that are understood by all receivers and enable receivers to provide good facilities to their users; ? the behaviour required from receivers to work well with these broadcasts and to be attractive to consumers. To avoid doubt, the words “shall”, “should” etc. are used in the traditional way to distinguish issues that are important versus those that are optional. The term “shall” is also used to identify mandatory requirements that are inherited from other specifications that have greater force. This specification does not consider interactive applications and the data broadcasting that would support them. Subtitling and teletext are considered to be components of TV services. Standalone teletext services are not part of this standard. This specification primarily addresses terrestrial delivery of digital transmissions. This specification primarily addresses deployment in countries that use European Latin script based languages.

BS EN 55020:2002 有声和电视广播接收机及相关设备.抗扰特性.极限值和测量方法

This standard for immunity requirements applies to television broadcast receivers, sound broadcast receivers and associated equipment intended for use in the residential, commercial and light industrial environment. This standard describes the methods of measurement and specified limits applicable to sound and television receivers and to associated equipment with regard to their immunity characteristics to disturbing signals. This standard is also applicable to the immunity of outdoor units of direct to home (DTH) satellite receiving systems for individual reception. NOTE 1 Receiving systems for collective reception, in particular cable distribution head ends (Community Antenna Television, CATV) and community reception systems (Master Antenna Television, MATV) are covered by IEC 60728-2. NOTE 2 Broadcast receivers for digital signals are covered by Annex I and Annex J. Immunity requirements are given in the frequency range 0 Hz to 400 GHz. Radio-frequency tests outside the specified frequency bands or concerning other phenomena than given in this standard are not required. The objective of this standard is to define the immunity test requirements for equipment defined in the scope in relation to continuous and transient, conducted and radiated disturbances including electrostatic discharges. These test requirements represent essential electromagnetic immunity requirements. Test requirements are specified for each port (enclosure or connector) considered. NOTE 3 This standard does not specify electrical safety requirements for equipment such as protection against electric shocks, unsafe operation, insulation co-ordination and related dielectric tests. NOTE 4 In special cases, situations will arise where the level of disturbances may exceed the levels specified in this standard e.g. where a hand-held transmitter is used in proximity to an equipment. In these instances special mitigation measures may have to be employed. The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations which are included: - residential properties, e.g. houses, apartments, etc.; - retail outlets, e.g. shops, supermarkets, etc.; - business premises, e.g. offices, banks, etc.; - areas of public entertainment, e.g. cinemas, public bars, dance halls, etc.; - outdoor locations, e.g. petrol stations, car parks, amusement and sports centres, etc.; - light-industrial locations e.g. workshops, laboratories, service centres, etc.; - car and boat. Locations which are characterized by their mains power being supplied directly at low voltage from the public mains are considered to be residential, commercial or light industrial.
