在计算机技术迅速发展的时代,有线电视网络技术也在不断地升级更新。为了适应时代发展的需要,要加快网络技术的改造,目前进行的是双向网络改造。在我国的广电网络中存在着很多的HFC网络,即光缆混合和同轴电缆网络,且有一部分网络都不具有双向功能,没办法满足多媒体交互的需要,只能够进行一些基础的改造,因此需要快速地完成HFC网络的双向改造,从而实现网络的稳定性发展,提高网络数据和电视信号的高质量的传输。本文从有线电视网络的发展现状、有线电视网络双向改造的重要性、有线电视网络的改造技术以及改造方案四个方面对有线电视网络改造技术及发展进行详细地阐述,以推进我国有线电视网络技术的改进和发展。
In the era of rapid development of computer technology, CATV network technology is constantly upgrading and updating. In order to meet the needs of the development of the times, it is necessary to speed up the transformation of network technologies. At present, two-way network transformation is under way. There are many HFC networks in China’s radio and television network, that is, fiber-optic cable hybrid and coaxial cable networks, and some networks do not have a two-way function, there is no way to meet the needs of multimedia interaction, only to make some basic transformation, and therefore need HFC network to complete the two-way transformation, in order to achieve the stability of the network development, improve network data and television signals of high quality transmission. This paper elaborates the technology and development of CATV network transformation from four aspects: the current situation of CATV network, the importance of two-way cable network transformation, the transformation technology of CATV network and the transformation scheme, in order to promote the development of CATV network technology Improvement and development.
