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.
下面是Intel® CE 2110媒体处理器的性能介绍.
The Intel® CE 2110 Media Processor provides the performance and headroom to support the deployment of innovative applications and services on digital set top boxes and digital media recorders. The Intel® CE 2110 Media Processor Development Platform is designed to reduce time-to-market for new applications and support the transition to Intel CE 2110 Media Processor SoC architecture. The Intel CE 2110 Media Processor reference platform provides the foundation for rapid development of new customer designs and product demonstrations.
The highly integrated Intel CE 2110 Media Processor helps to simplify the design of consumer electronics products with reduced BOM cost. The integrated Intel XScale® processor core at 1GHz provides processing performance and headroom to deploy new revenue-generating applications.
