2.6  Video stream types  

Motion JPEG   

This format uses standard JPEG images in the video stream. These images are then displayed 

and updated at a rate sufficient to create a stream that shows constantly updated motion.   

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent 

image quality and access to every individual image contained in the stream.   

H.264 Protocols & Communication Methods   

- RTP (Real-time Transport Protocol) is a protocol that allows programs to manage the real-time 

transmission of multimedia data, via unicast or multicast.   

- RTSP (Real-Time Streaming Protocol) serves as a control protocol, to negotiate the type of 

transport protocol used for the stream. RTSP is used by a viewing client to start a unicast session   

- UDP (User Datagram Protocol) is a communications protocol that offers limited service for 

exchanging data in a network which uses the Internet Protocol (IP). UDP is an alternative to the 

Transmission Control Protocol (TCP). The advantage of UDP is that it is not required to deliver all 

data and may drop network packets when there is network congestion. This is suitable for live 

video, as there is no point in re-transmitting old information that will not be displayed anyway.
