RTSP means Real Time Streaming Protocol, is a protocol specifically designed for streaming purpose, with RTSP you can control absolute positioning within the media stream, recording and possibly device control etc
If you want to use video streaming you have to use RTSP
See this LINK for more details about the protocol RTSP
NB
To show the video content in Android you can use the VideoView
myVideoView = (VideoView) findViewById(R.id.myview);
myVideoView.setVideoPath("rtsp://SERVER_IP_ADDR:5544/");
myVideoView.setMediaController(new MediaController(this));
As described HERE
