我国有线电视网络正全面展开数字化工作,本期特别关注将话题引入数据网络的建设与业务开发,从案例、规划、业务、技术等几个方面组织了相关稿件,涉及了宏观及微观的话题,其中技术与业务的讨论未必适合每一个地区,但希望籍此能够起到抛砖引玉的作用,引发业界对数据网络建设及业务开发的思考与实践,促进我国有线电视网络向综合业务的方向发展。 The CATV network in China is now fully engaged in digitalization. In this issue, special attention was paid to the introduction of the topic into the construction of data networks and business development. Relevant manuscripts were organized from the aspects of case, planning, business and technology, covering macro and micro topics. The technical and business discussions may not be suitable for every region. However, I hope they can play a valuable role in initiating the thinking and practice of data network construction and business development in the industry and promote the development of China’s cable television network towards integrated services.
