最近有些專案需要在web browser 上面崁入IP cam 的即時影像，想起來好像很簡單，不就是把webcam 所提供的 http brwoser 瀏覽服務的 IP Address 直接崁入到我們的 html 中的 ifram 就好了，不過仔細查了一些文章都有提到走 HTTP 協定的 web cam 是有一些限制及缺點。
例如當使用HTTP streaming 傳送 video streaming (jpeg images or video frames) 到手機裝置或是桌機的 browser 時可能會有5到10秒鐘的時差，因為 http 通訊協定天生就不是那麼適合傳送很即時的 realtime 無時差資訊這時後就需要RTSP 或是RTP協定了。
