描述

开发人员现在可以在数字视频设计中以30fps的速度提供高达720p H.264的像素完美图像，而无需考虑视频格式支持，网络带宽受限新型TMS320DM365数字媒体处理器基于德州仪器（TI）的DaVinci技术，有限的系统存储容量或成本。凭借多格式高清视频，DM365还具有一套外设，可为开发人员节省系统成本。

这款基于ARM9的DM365设备提供高达300 MHz的速度，并支持符合生产要求的H.264，MPEG -4，MPEG-2，MJPEG和VC1 /WMV9编解码器，使客户能够灵活地为其应用选择正确的视频编解码器。这些编解码器由视频加速器驱动，从ARM内核卸载压缩需求，以便开发人员可以利用ARM的最高性能来实现其应用。视频监控设计人员可以实现更高的压缩效率，从而在不影响网络带宽的情媒体播放和相机驱动应用的开发人员，如视频门铃，数字标牌，数字视频录像机，便携式媒体播放器等，可以利用DM365支持的全套编解码器，确保互操作性和产品可扩展性。 /p>

与多格式高清视频一起，DM365可实现与视频应用所需的大多数其他外部设备的无缝接口。图像传感器接口足够灵活，可支持CCD，CMOS和各种其他接口，如BT.656，BT1120。 DM365还提供高清集成，支持高清显示，包括3个内置10位高清模拟视频数模转换器（DAC），DDR2 /mDDR，以太网MAC，USB 2.0，集成音频，主机端口接口（ HPI），模数转换器以及更多功能可以为开发人员节省整体系统成本以及电路板上的空间，从而实现更纤薄，更时尚的设计。
