        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攝像機參考設(shè)計。該 DM368IPNC-MT5 IP 攝像機參考設(shè)計支持 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 攝像機參考設(shè)計基于全新達芬奇 (DaVinci) 視頻處理器,與前代產(chǎn)品相比,可將主機處理性能提高 30%。這種總體性能的提升使攝像機不但可支持 60 幀每秒 720p,滿足包括 H.264 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,敬請訪問:www.ti.com/1080p-ipcamrd-prprod)。 

此外,該 IP 攝像機參考設(shè)計還包含一個完整的 Linux 應(yīng)用軟件包,可幫助客戶為其終端攝像機實現(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)(PSIAwww.psialliance.org),從而可實現(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 攝像機或閉路電視 IP 攝像機等具有全高清視頻的低成本產(chǎn)品,大幅縮短開發(fā)時間。 

 

DM368IPNC-MT5 IP 攝像機參考設(shè)計的主要特性與優(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 60 幀每秒 720p 

o                     可達60 幀每秒 720p MPEG-4 

o                     幀速率為 15 幀每秒 的 5MP MJPEG 

·             與前代產(chǎn)品相比,全新達芬奇視頻處理器的 ARM 主機處理性能提高了 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)計采用 TI 以太網(wǎng)供電 (PoE) 解決方案—— TPS23753PWP,功耗僅為 3 瓦; 

·             TI 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,便可實現(xiàn)高質(zhì)量影像。此外,客戶無需消耗大量的時間和資源去創(chuàng)建自己的定制算法; 

·             ISP 上實施軟件,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等功能,而且還可實現(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)計包括全面互補型模擬 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)時間; 

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

 

參考設(shè)計包括完整的 Linux 應(yīng)用軟件: 

客戶通過購買 IP 攝像機參考設(shè)計將獲得完整的免專利費 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施與即插即用連接; 

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

·             全域動態(tài)范圍強化 (GDRE) 可使用戶在無需沖淡重點顯示部分的情況下,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。
