Can I record / save JPEG files from an MJPEG stream? (as well as MJPEG itself)?

Question

I am using MJPEG-Streamer to stream MJPEG video files via http, it looks like this guy is doing this . MJPEG-Streamer basically creates a streaming server on a streaming device that hosts MJPEG streaming video. Access to this stream is possible through http://<Server-IP-address>:8080/?action=stream. An example of this is http://sigsiu.homeip.net/?action=stream . Pictures can be recorded withhttp://<Server-IP-address>:8080/?action=snapshot

What is interesting to me, this is the format in which the received stream: /?action=stream. Is this the usual protocol for streaming media, or is it something specific to MJPEG-Streamer?

Most importantly, it would be possible so that I can extract JPEG / MJPEG when it is broadcast through /?action=stream

I am very new to streaming real-time video over the Internet, so I have no idea how to say that streaming MJPEG-Streamer is a very standard way in which it would be easy to extract JPEG / MJPEG; or if its streaming in some esoteric way is a little mysterious where it is difficult to extract JPEG / MJPEG.

Thanks!

Additional Information: I plan to receive / capture the MJPEG stream on an Android device.
