基于Intel CE 2110媒体处理器的Moxi解决方案

Intel CE 2110媒体处理器是针对消费电子的Olo River平台的第一款SoC。相比之前基于CPU+芯片组的方案，集成度大幅提升，整体成本也下降。英特尔CE 2110媒体处理器内含功能强大的嵌入式1 GHz英特尔XScale CPU、MPEG-2和H.264硬件视频解码器、DDR2内存接口、以及2D/3D图形加速器，并具备模块化软件开发环境的支持。此外，该平台架构还支持消费电子开发商和制造商提供纯IP或混合机顶盒，以通过IP和数字广播信道接收内容。

采用硬件加速器后，CE2110整体方案的功耗明显下降，在主频达到最高1GHz时的功耗也仅为7W，而一般不需要使用最高主频时，其功耗更低。

英特尔在CE2110中选择了MEGP2和H.264两种解码方式，采用硬件加速器。前者是为了兼容现有的IPTV和其他机顶盒要求；后者则表现出英特尔对H.264的支持胜过MPEG4，H.264也是目前中国IPTV市场上一些城市将要采用的标准。
CE2110可以同时支持2路标清和1路高清电视信号。CE2110除了支持IPTV外，它还可支持IPTV与DVB-C、DVB-T、DVB-S的混合机顶盒。

目前，IPTV机顶盒提供商在提供有吸引力、并迅速响应的节目指南，以及通过有限的硬件平台进行实时高清IP视频流解压缩方面面临挑战。英特尔 CE 2110媒体处理器针对这些高级应用进行了优化，可满足功率和成本要求，是新一代Moxi DMR和基于Moxi的IPTV解决方案的理想选择。

The Moxi HD Digital Video Recorder (DVR) is Digeo’s next-generation cable DVR solution, following the successful Moxi Media Center introduced in late 2004. The Moxi HD DVR is a newly designed digital set top box that combines optimized hardware with the latest version of the industry-acclaimed Moxi software, to offer cable service providers nearly twice the storage of the previous Moxi Media Center at more than a third less cost. The new Moxi HD DVR capabilities include:

The Moxi Menu, featuring the fast and highly-graphical Moxi programming guide-- which integrates VOD and PPV content in search results and predefined content filter cards--and popular media center features such as Ticker, Photos and Games;


Moxi 4.1 software improvements including faster rendering time, time forward feature and hard

drive storage meter;

Remote web-based scheduling;

Built-in support for Multi-stream CableCARD (M-Card) with two-way capability;

The ability to record two simultaneous HD video streams: up to 16 hours of HD MPEG2 video, and up to 160 hours of standard-definition video on the 160GB hard drive;

External hard drive support, allowing provisioned subscribers to increase their storage to 1 terabyte;

Digeo Customer Connection portal access, providing diagnostic tools for Customer Service Representatives and insights into subscriber needs; and

Interoperability with both Motorola and Scientific-Atlanta-based cable plants.
