摘要
随着4K超高清节目的推广和普及,有线网络运营商越来越重视面向4K超高清节目的有线网络传输承载能力建设。为了评估并规范有线网络传输性能指标,本文开展了评估测试工作,并基于测试结果提出了面向4K超高清节目传输的有线网络技术要求建议。
With the gradual promotion and popularization of 4K UHD programs,cable network operators pay more and more attention to the carrying capacity of cable network transmission for 4K UHD programs.In order to evaluate and standardize the performance indicators of network transmission,Academy of Broadcasting Planning has carried out the evaluation and testing work,and has presented cable network technical requirements for 4K UHD program transmission based on the testing results.
