发展阶段	主要政策文件	政策核心内容
产业化发展	GB/T 17786-1999《有线电视频率配置》（现行）	整体上对各个频段的使用模式进行了定义；确定了以8 MHz作为频率使用单元
	GY/T106-1999《有线电视广播系统技术规范》（现行）	整体上对各个频段的使用模式进行了定义；确定了以8 MHz作为频率使用单元
数字化改造	《有线数字电视频道配置指导性意见（2003）》	数字化改造之后，下行频带（111～958 MHz）的使用细则
	GY/T 180-2001《HFC 网络上行传输物理通道技术规范》	数字化改造之后，上行频带（5～65 MHz）的使用细则；NGB的规范出台后，该规范逐步废弃
双向化改造（NGB启动）、三网融合	GY/T 265-2012《NGB HINOC接入控制技术规范》	各省新建的NGB 网络可自主选择遵循其中的一个标准	面向NGB网高频>750 MHz
	GY/T 266-2012《NGB C-DOCSIS技术规范》		面向中低频：下行111～750 MHz/上行0～65 MHz

R	5～65	上行业务
X	65～87	过渡带
VHF（FM）	87～108	广播业务
VHF	110～1 000	模拟电视、数字电视、数据业务
带外	>1 000	带外业务、数据业务

波段	规范说明

R	用于综合承载各类上行业务，业务用途最多元化，相互干扰最严重
X	用于避免大功率广播信号与上行信号的频率污染留出的隔离带
VHF（FM）	为调频、数据广播（非电视信号）单独预留的专用频段，一般不另做他用，按不小于400 kHz的载频间隔配置频率点
VHF	由国家广播电影电视总局相关技术标准与指导文件严格规范使用
带外	有线电视系统频道不使用
