Description
技术领域technical field
本发明涉及广播电视网络领域，特别是涉及一种基于LTE加同轴电缆的双向宽带接入及互动点播系统。The invention relates to the field of radio and television networks, in particular to a two-way broadband access and interactive on-demand system based on LTE plus coaxial cables.
背景技术Background technique
广播电视技术经过几十年的发展，随着人民群众物质生活水平的提高，单向的广播电视已经满足不了用户的需求，现在已经大规模的应用VOD（视频点播）技术，有基于有线电视网络和基于互联网的VOD应用。其中基于有线电视网络的VOD应用体验和效果最佳，但是有线电视网络要实现VOD必须进行双向网络改造，将传统的单向广播网络改造成具备双向通信功能的基础网络。当前的双向网络改造成本高，而且对于改造的区域，不管用户有没有双向应用需求，都必须全部改造，当业务渗透率低的情况下投资将得不到回报。After decades of development of radio and television technology, with the improvement of people's material living standards, one-way radio and television can no longer meet the needs of users. Now VOD (video on demand) technology has been applied on a large scale, and there are cable TV network-based and Internet-based VOD applications. Among them, the VOD application experience and effect based on the cable TV network are the best, but the cable TV network must carry out two-way network transformation in order to realize VOD, and transform the traditional one-way broadcast network into a basic network with two-way communication functions. The current two-way network transformation costs are high, and for the transformed area, no matter whether the user has two-way application requirements, all must be transformed. When the service penetration rate is low, the investment will not be returned.
为了利用单向广电有线电视网络提供宽带及互动点播服务，可以不改造单向有线电视网络，直接利用技术成熟的4G LTE无线网络来解决双向通信问题，利用该无线传输通道来提供宽带接入及满足VOD系统的信令PORTAL页面传输需求，利用有线电视网络单向传输VOD点播请求的视频流内容。In order to provide broadband and interactive on-demand services using the one-way cable TV network, the mature 4G LTE wireless network can be directly used to solve the two-way communication problem without transforming the one-way cable TV network, and the wireless transmission channel can be used to provide broadband access and Meet the signaling PORTAL page transmission requirements of the VOD system, and use the cable TV network to unidirectionally transmit the video stream content requested by VOD.
当前有线电视网络的单向同轴电缆网络，在没有经过双向网络改造之前仅能单向接收广播电视节目，无法为终端提供双向网络服务，这样大大限制用户体验，用户得不到宽带业务及视频点播服务。由于单向同轴电缆网络，覆盖千家万户，要进行双向改造需要投入大量的资金和更换全网的放大器、分支分配器、测试评估反向回传通道的噪声情况；进行双向改造工程周期长，工程量浩大。The one-way coaxial cable network of the current cable TV network can only receive broadcast TV programs in one direction before the two-way network transformation, and cannot provide two-way network services for terminals, which greatly limits user experience, and users cannot get broadband services and video On-demand service. Since the one-way coaxial cable network covers thousands of households, a large amount of capital needs to be invested and the replacement of amplifiers and branch distributors in the entire network, as well as testing and evaluating the noise of the reverse return channel for two-way transformation; the two-way transformation project takes a long time , The project volume is huge.
