近来,对于有线电视双向改造方面的讨论如火如荼,本刊2-4期也连续做了三期专题讨论。我们所能做的也只是把有关专家的观点与看法、网改相关技术与成本的比较,以及部分地区的实践体会与经验客观地呈现给业界。至于结论,大概只有四个字:因地制宜。有线电视网络向双向化发展,这是大势所趋,是我们业务发展及未来空间拓展的基础建设,更是我们在下一步的“三网融合”中能够争取到相应位置的重要技术保障。对于一些经济发达的地区,对于一些已经完成整体转换、正考虑如何迎接“后平移时代”的网络公司而言,双向改造及双向业务的开发已经提上了日程。 Recently, discussions on the bidirectional transformation of cable television are in full swing, and Phase 2-4 of this issue has also continuously conducted three thematic discussions. What we can do is to compare the views and opinions of relevant experts with the related technologies and costs of net reform as well as the practical experience and experience in some areas objectively presented to the industry. As for the conclusion, only about four words: according to local conditions. The bidirectional development of CATV network is the trend of the times. It is an infrastructure for our business development and future expansion of space. It is also an important technical safeguard for us to win the corresponding position in the next step of “triple play.” For some economically developed regions, the development of two-way transformation and two-way business has been put on the agenda for some network companies that have completed the conversion and are considering how to meet the “post-translation era.”
