實作能穿透NAT達到P2P傳送影像封包的系統,並在三個不同的移動式平台上實現,分別為VPON行車紀錄器、Pcam網路攝影機與Android網路攝影機,研究方向如下列幾點。 a. NAT穿透 b. 影像流量控制 c. 影像重傳機制 d. SIP/RTP e. 營運成本分析 在三個不同系統的平台上,實作出來,測試市面上所販售的50款NAT進行交叉測試比較,能穿透NAT的成功機率高達95%,且在不走到relay的情況下,每個設備的頻寬成本只需一塊錢,最後再計算使用本系統與不使用本系統的成本計算。
Implement NAT traversal video streaming system on three different mobile platform, VPON Tachograph、Pcam IPcam and Android IPcam respectively. The research topics are listed as below: a. NAT traversal b. Video Flow control c. Re- transmission d. SIP/RTP e. Operation cost analysis These five sub-systems are implemented on three different mobile platforms . More than 50 NATs cross-test, NAT traversal probability of success high as 95% , and calculated using this system and do not use this system cost.
