TI公司的DSP可用于将图像压缩成多种标准和非标准的视频格式。另外，TI公司的DSP还具有智能图像分析功能，且支持多种类型的网络协议。 下图为基于TMS320DM64x处理器的数字录像机解决方案的方框图  数字录像机的主要元器件为TMS320DM64x 数字媒体处理器 下面对元器件的性能和方框图进行描述： TI’s video surveillance solutions are primarily based on the high-performance DM64x DSP-based digital media processors. The DM64x DSP-based digital media processors have on-chip video ports for easy connection to video devices and are capable of handling both video and audio encode and decode for IP-based video surveillance applications. The single, programmable digital media processor is a cost-effective solution because the need for external PCI or EMAC is eliminated. Key Features ★ Performance up to 5760 MIPS at 720 MHz ★ 400/500/600 MHz options also available ★ Multiple input/output glueless interfaces for common video and audio formats ★ Performance real-time video encoding, decoding and/or transcoding ★ Three dual-channel video ports support simultaneous video input and output ★ Advanced connectivity with 10/100 Ethernet MAC and 66-MHz PCI ★ Ready-to-use application software such as MPEG4, MPEG2, MPEG1,WMV9, H.263, H.261, M-JPEG, JPEG2000, JPEG, H.264 and more Applications ★ Network camera-based surveillance and IP video node ★ Video-on-demand set-top boxes, personal video recorders and digital media centers ★ Statistical multiplexers and broadcast encoders ★ IP-based video conferencing and IP-based videophones  TMS320DM642数字媒体处理器方框图 |
