MoCA技术在美国已占据90%以上市场份额

2013年10月14日，MoCA联盟相关人士在接受融合网|DWRH.net独家采访时，围绕着国内外广电领域尤其是有线领域进行广泛而深入的交流。

融合网|DWRH.net：请您介绍一下，目前在中国和全球，都有哪些电信运营商或者是广电运营商在网络双向化改造方面使用了MoCA技术？

Could you please talk about which carriers and/or radio and television operators have adopted MoCA technologies in the two-way network transformation currently in China and globally?

MoCA联盟：在美国，除了一家付费电视运营商外，其余的运营商都在采用MoCA技术。这项技术在美国占据了90%以上的市场份额。

MoCA technology is in use by every major pay TV operator in the U.S except one. The technology enjoys more than 90 percent market share in the US.

MoCA技术是唯一三个付费电视领域（有线、卫星和电信）都在使用的有线家庭网络技术。它还是唯一将来持续增长的有线家庭网络技术。

It is the only wired home networking technology in use by all three pay TV segments—cable, satellite and telco. It is also the only wired home networking technology that will continue to grow after next year。

这项技术在五大洲——北美、南美、亚洲、南非和欧洲处于测试或者部署阶段。

The technology is in trials or deployment on five continents-North America, South America, Asia, South Africa and Europe.

融合网|DWRH.net：中国各地的有线电视网络运营商（比如，天津市有线、贵州省有线、江苏省有线等）应用MoCA技术之后，近几年的实际应用情况如何？

China's cable TV network operators including Tianjin cable TV, Guizhou cable TV, Jiangsu cable TV and so on have adopted MoCA technology, could you please introduce its practical applications over the recent years?

MoCA联盟：我暂时不方便公开运营商的名称及其计划，但是使用MoCA技术进行家庭高清内容传输的服务提供商确实遍布全球。具体的应用包括多房间DVR（在美国和欧洲比较流行）、游戏和OTT视频在线点播。众多运营商使用MoCA产品加强无线网络，使消费者可以在家里的各个角落接收网络内容。

I cannot speak publicly about operators and their plans, but service providers worldwide use MoCA technology for the distribution of high definition content around the home. Applications include multi-room DVR (popular in the US and Europe), gaming and over the top video streaming. Many operators use MoCA –enabled products to enhancewireless networks so that the consumer can receive content anywhere in the home.

融合网|DWRH.net：广大用户家中的HFC这根网络与其他网络（比如，无线、电力线等）相比，有哪些优势？

Could you please talk about the advantages of an HFC (Hybrid Fiber Coaxial) network that are widely adopted in China compared with other networks (e.g. wireless and power lines)?

MoCA联盟：HFC是一种网络或者宽带接入技术。这种技术用于向家庭传输内容，而MoCA用在在家庭内部传输内容。MoCA技术兼容所有网络接入技术。

HFC is a network or broadband access technology. It is a technology for delivering content TO the home. MoCA is a technology for IN the home. MoCA technology works with any network access technology.

无线是平板电脑和智能手机等便携设备的最佳技术，这些设备无需使用线缆即可以连接到因特网上。然而，无线技术是一种共享媒体，所有的用户共同分享可用带宽的一部分，而非全部。这样高清视频在线点播的质量会受到极大的影响。无线还可能干扰其它家庭设备和技术，这样也会影响视频的质量。但是，如果家庭面积较小，或者仅有一两名使用者，无线也许能够满足大多数应用的需求。

Wireless is the best technology for portable devices as tablets and smartphones as these devices do not use wires to connect to the Internet. However, wireless technology is a shared medium so all users only get a portion of available bandwidth, not all of it. This will severely impact HD video for instance. Wireless is also prone to interference with other devices and technologies in use in the home which also affects video. However, if the home is small, or there is only one or two users in the home, wireless may prove adequate for most applications.

每个家庭都会安装电力线，这非常适用于电子邮件或者微博等不需要较大带宽的数据应用。但是电力线也容易干扰其它设备和技术，不能使高清视频实现最佳的质量。

Powerline is pervasive throughout the home and is well suited for data-specific applications that do not require a lot of bandwidth such as email or Weibo. But powerline is also prone to interference with other devices and technologies in use and is not reliable for high definition video.

融合网|DWRH.net：据融合网|DWRH.net最新统计数据显示，目前全国还有近一亿的有线电视网络用户需要完成双向化改造，成本和未来能开展哪些业务是各地有线电视网络运营商在进行双向化改造之前重点考虑的几个因素。在这方面，MoCA技术有哪些优势？MoCA技术在成本上有哪些具体的优势？

According to the latest statistics collected by DWRH.net, at present, China has over nearly 100 million cable television network users who are awaiting two-way network transformation around the country. The local cable TV operators will give top priority to the cost and its future business models before conducting two-way network transformation.  what are MoCA’s prevailing advantages in this regard? Besides, what are MoCA’s specific advantages in terms of cost?

MoCA联盟：MoCA技术为目前的家庭网络标准提供最高的性能和可靠性。这种技术利用现有的同轴电缆，无需升级以太网/Cat5等线缆。

MoCA technology offers the highest performance and reliability over any home networking standard available today. The technology will work over any coaxial cabling that exists. There is no need to upgrade the wire like Ethernet/Cat5.

因为MoCA技术非常可靠，所以它可以立即进行安装，运营商和消费者可以一劳永逸。因为它会一直发挥作用，所以用户无需向付费电视运营商抱怨他们的服务。他们会非常满意。客户满意才能实现利润。MoCA能够使客户满意，并且使运营商获利。(责任编辑：韩杰)
