英汉对照有线电视网络常用缩语(一)【引言】由于有线电视网络术语大多数由国外翻译而来,中国现已是世贸组织(WTO)成员,国内外技术交流(包括技术资料互译)肯定会不断加强,有线电视网络技术人员不但需要掌握中文术语,而且需要掌握外文(主要是英文)术语。鉴于目前查阅英汉有线电视术语的资料缺乏,笔者经过收集、对照、翻译,形成如下较全面的“英汉对照有线电视网络专业术语”(以英文术语字母为序),以满足大家的需要。【正文】AAL(ATMAdaptationLayer):异步转移模式适配层AC(AlternatingCurrent):交流AccessNetwork:接入网ACI(AdjacentChannelInterference):邻频干扰AdditionalChannel:增补频道AdjacentChannelTransmission:邻频道传输ADSL(AsymmetricalDigitalSubscriberLine):不对称数字用户线路AGC(AotomaticGainControl):自动增益控制AIC(AuxilliaryInformationChannel):辅助信息信道ALC(AotomaticLevelControl):自动电平控制AM(AmplitudeModulation):幅度调制(调幅)AML(AmplitudeModulatedMicrowaveLink):调幅微波链路Amplifier:放大器ApplicationLayer:应用层ARP(AddressResolutionProtocol):地址识别协议ASC(AotomaticSlopeControl):自动斜率控制ATM(AsynchronousTransferMode):异步传输模式(协议)BAL(BitALlocation):比特分配Bandwidth:带宽BB(BasisBand):基带BBER(BackgroundBlockErrorRate):背景块误码率BC(BroadcastChannel):广播信道BCN(BroadcastCommunicationNetwork):广播通信网BDC(BlockDownConverter):下变频器BER(BitErrorRate):误码率B-ISDN(Broadband-IntegratedServicesDigitalNetwork):宽带综合业务数字网络BitStream:比特流(码流)BPF(BandPassFilter):带通滤波器BPS(BitsPerSecond):比特/秒,也写作b/sBRI(BasicRateInterface):基本速率接口BroardBandCommunication:宽带通信BRR:(BitRateReduction):比特率压缩C/CSO(CarriertoCompositeSecondOrderbeatratio):载波复合二次差拍比C/CTB(CarriertoCompositeTripleBeatratio):载波复合三次差拍比C/I(CarriertoInter-modulationratio):载波互调比C/N(CarriertoNoiseratio):载噪比CA(ConditionalAccess):有条件存取(有条件接收)CableRouter:线缆路由器CAC(ConditionalAccessControl):条件接收控制CAID(ConditionalAccessIDentifier):有条件存取(接收)标志CATV(CableTeleVision):有线电视CATV(CommunityAntennaTeleVision):共用天线电视CCIR(InternationalRadioConsultativeCommittee):国际无线电咨询委员会CCITT(ConsultativeCommitteeofInternationalTelephoneandTelegraph):国际电报电话咨询委员会CCU(CommunicationControlUnit):通信监测单元CDMA(CodeDivisionMultipleAccess):码分多址Channel:频道Channel:信道Chirp:附加调频CIF(CommomInterleavedFrame):公共交织帧CII(ChinaInformationInfrastrcture):中国信息基础设施(计划)CircuitSwitching:电路交换CLI(CATVLeakageandIngress):有线电视泄漏与窜入CM(CableModem):电缆调制解调器又名线缆调制解调器CM(CrossModulation):交扰调制CMCI(CableModemtoCPEInterface):电缆调制解调器至用户屋内设备接口CMTRI(CableModemTelephoneReturnInterface):电缆调制解调器中回传电话接口CMTS(CableModemTerminationSystem):电缆调制解调器(CableModem)端接系统CoaxialCable:同轴电缆COFDM(CodedOrthogonalFrequencyDivisionMultiplexing):编码正交频分复用Communication:通信CommunityReception:集体接收CPE(CustomerPremisesEquipment):用户屋内设备CS(CommunicationSatellite):通信卫星CSMA/CD(CarrierSenseMultipleAccess/CollisionDetection):公共载波复用通路/冲突检测(用于以太网),也叫带碰撞检测的载波侦听多址、载波侦听多重接入/碰撞检测CSO(CompositeSecondOrderBeat):复合二次差拍CTB(CompositeTripleBeat):复合三次差拍CW(ControlWord):控制字英汉对照有线电视网络常用缩语(二)Data:数据DAVIC(DigitalAudioVideoCouncil):数字音视频理事会DB(DataBroadcasting):数据广播dB(deciBel):分贝DBS(DirectBroadcastSatellite):直播卫星DC(DirectCurrent):直流DCF(DispersionCompensationFiber):色散补偿光纤,也叫色散位移光纤DC-SMF(DispersionCompensationSingleModeFiber):色散补偿单模光纤DCT(DiscreteCosineTransform):离散余弦变换DFB(DistributedFeedBack):分布反馈(激光器)DFB-LD(DistributedFeedBack-LD):分布反馈型-激光二极管DFT(EiscreteFourierTransformation):离散傅里叶变换DHCP(DynamicHostConfigurationProtocol):动态主机配置协议DIB(DigitalIntegratedBroadcasting):数字综合广播Digital:数字的DistributionPoint:分配点DLL(DataLinkLayer):数据链路层DLS(DynamicLabelSegment):动态标记段DMB(DigitalMultimediaBroadcasting)数字多媒体广播DOCSIS(DataOverCableServiceInterfaceSpecification):有线电视网络上的数据接口规格Downstream:下行DQDB(DistributedQueueDoubleBus):分布队列双总线DRC(DynamicRangeControl):动态范围控制DSCTy(DataServiceComponentType):数据业务成分类型DSF(DispersionShiftFiber):色散位移光纤DSL(DigitalSubscriberLine):数字用户线路DSM(DigitalStorageMedia):数字的存储或传输器件DSP(DigitalSignalProcessor):数字信号处理器DTV(DigitalTV):数字电视DVB(DigitalVideoBroadcasting):数字视频广播DVB-C(DigitalVideoBroadcasting-Cable):用于电缆的数字视频广播DWDM(DensenessWavelengthDivisionMultiplexing):密集波分复用DXC(DigitalCrossConnection):数字交叉连接(设备)EBU(EuropeanBroadcastingUnion):欧洲广播联盟EchoRating:回波值ECM(EntitlementCheckingMessage):授权校验信息EDFA(Erbium-DopedFiberAmplifier):掺饵光纤放大器EDTV(EnhanceddefinitionTelevision):增强清晰度电视EIA(ElectronicIndustriesAssociation):电子工业协会EIRP(EquivalentIsotropicRadiatedPower):等效全向辐射功率Eld(EnsembleIdentifier):信号群(组)标志EMM(EntitlementManagementMessage)授权管理信息EPG(ElectronicProgramGuides):电子节目指南Equalization:均衡ERP(EquivalentRadiatedPower):等效辐射功率ESR(ErrorblockSecondRatio):误块秒率Ethernet:以太(网)ETI(EnsembleTransportInterface):信号群(组)传输接口ETI(NA){EnsembleTransportInterface(Network-Adapted)}:网络适应的信号群(组)传输接口ETI(NI){EnsembleTransportInterface(Network-IndependentETI)}:网络独立的信号群(组)传输接口ETN(Ensemble-Transport-Network):信号群(组)传输网络ETS(EuropeanTelecommunicationsStandard):欧洲通信标准ETSI(EuropeanTelecommunicationsStandardsInstitute):欧洲通信标准学会FCC(FederalCommunicationsCommission):联邦通信委员会FDDI(FiberDistributingDataInterface):光纤分布式数据接口FDM(FrequencyDivisionMultiplexing):频分复用FDMA(FrequencyDivisionMultipleAccess):频分多址FEC(ForwordErrorCorrection):前向纠错Feed:馈送FeedbackErrorCorrection:反馈纠错FF(FeedForword):前馈(放大器)FFT(FastFourierTransformation):快速傅里叶变换FI(FrequencyInformation):频率信息FIB(FastInformationBlock):快速信息块FIC(FastInformationChannel):快速信息信道FIDC(FastInformationDataChannel):快速信息数据通道FIDCId(FastInformationDataChannelIdentifier):快速信息数据通道标志FIG(FastInformationGroup):快速信息组FM(FrequencyModulation):频率调制(调频)FML(Frequency
