        日前，德州儀器 (TI) 宣布面向視頻監(jiān)控市場推出一款支持低功耗、高清 (HD) 視頻處理的全新IP攝像機(jī)參考設(shè)計(jì)。該 DM368IPNC-MT5 IP 攝像機(jī)參考設(shè)計(jì)支持 30 幀每秒H.264 主類 1080p，可為全高清解決方案提供業(yè)界領(lǐng)先的壓縮功能，總功耗僅為 3 瓦。該款 IP 攝像機(jī)參考設(shè)計(jì)基于全新達(dá)芬奇 (DaVinci) 視頻處理器，與前代產(chǎn)品相比，可將主機(jī)處理性能提高 30%。這種總體性能的提升使攝像機(jī)不但可支持 60 幀每秒 720p，滿足包括 H.264 與 MPEG-4 在內(nèi)的多種視頻格式的需求，而且還可支持幀速率為 15 幀每秒的五百萬像素MJPEG。此外，該產(chǎn)品還可在各種幀速率下支持多視頻流處理（更多詳情，敬請?jiān)L問：www.ti.com/1080p-ipcamrd-prprod）。 

此外，該 IP 攝像機(jī)參考設(shè)計(jì)還包含一個(gè)完整的 Linux 應(yīng)用軟件包，可幫助客戶為其終端攝像機(jī)實(shí)現(xiàn)差異化特性。該應(yīng)用軟件包包含影像信號處理 (ISP) 調(diào)試工具 1.0 與硬件加速 AES 加密模塊，并支持物理安全互操作性聯(lián)盟標(biāo)準(zhǔn)（PSIA：www.psialliance.org），從而可實(shí)現(xiàn)更便捷的使用與部署。將這些優(yōu)勢相結(jié)合，可幫助客戶快速創(chuàng)建如 IP 攝像機(jī)或閉路電視 IP 攝像機(jī)等具有全高清視頻的低成本產(chǎn)品，大幅縮短開發(fā)時(shí)間。 

 

DM368IPNC-MT5 IP 攝像機(jī)參考設(shè)計(jì)的主要特性與優(yōu)勢： 

·             具備高度的靈活性，可支持各種視頻格式，包括： 

o                     30 幀每秒 H.264 主類 1080p 或 60 幀每秒 720p 

o                     可達(dá)60 幀每秒 720p 的 MPEG-4 

o                     幀速率為 15 幀每秒 的 5MP MJPEG 

·             與前代產(chǎn)品相比，全新達(dá)芬奇視頻處理器的 ARM 主機(jī)處理性能提高了 30%，可為產(chǎn)品差異化與視頻分析提供更多的預(yù)留空間； 

·             低功耗參考設(shè)計(jì)采用 TI 以太網(wǎng)供電 (PoE) 解決方案—— TPS23753PWP，功耗僅為 3 瓦； 

·             TI 第 5 代片上 ISP 解決方案無需外部 ISP 或購買昂貴的光學(xué)器件，便可實(shí)現(xiàn)高質(zhì)量影像。此外，客戶無需消耗大量的時(shí)間和資源去創(chuàng)建自己的定制算法； 

·             在 ISP 上實(shí)施軟件，不但可提供視頻穩(wěn)定性、面部檢測、噪聲過濾、自動白平衡、自動對焦、自動曝光以及邊緣增強(qiáng)等功能，而且還可實(shí)現(xiàn)其它視頻處理特性，從而提高質(zhì)量、改善影像； 

·             該參考設(shè)計(jì)包括全面互補(bǔ)型模擬 IC，從電源管理到 TI 接口器件，一應(yīng)俱全，從而可提供完整的系統(tǒng)解決方案，縮短開發(fā)時(shí)間； 

·             與 Appro Photoelectron 公司合作開發(fā)，并通過該公司供貨。 

 

參考設(shè)計(jì)包括完整的 Linux 應(yīng)用軟件： 

客戶通過購買 IP 攝像機(jī)參考設(shè)計(jì)將獲得完整的免專利費(fèi) Linux 應(yīng)用軟件包，其中包括： 

·             ISP 調(diào)試工具 1.0，該工具可用于調(diào)試參考設(shè)計(jì)包含的現(xiàn)有傳感器，或者與客戶自己開發(fā)的傳感器電路板配合使用； 

·             PSIA 1.0 支持，可確保與符合 PSIA 標(biāo)準(zhǔn)的系統(tǒng)的連接，從而提供更便捷地實(shí)施與即插即用連接； 

·             AES 加密，可為視頻流提供更高的保護(hù)與隱私，從而增強(qiáng)用戶終端系統(tǒng)的安全性； 

·             全域動態(tài)范圍強(qiáng)化 (GDRE) 可使用戶在無需沖淡重點(diǎn)顯示部分的情況下，在視頻的陰影中突出細(xì)節(jié)，這是視頻安全監(jiān)控的重要特性。此外，GDRE 還可補(bǔ)償?shù)统杀?span lang="EN-US"> CMOS 傳感器降低的動態(tài)范圍，使客戶能夠開發(fā)更低成本的系統(tǒng)。 

·             針對具體客戶定制化與差異化的 Linux 源代碼。
