3.5 Video Stream Types
H.264 Protocols and Communication Methods:
o
Real-time Transport Protocol (RTP):
RTP is a protocol that allows programs to manage the real-time
transmission of multimedia data, via unicast or multicast.
o
Real Time Streaming Protocol (RTSP):
RTSP serves as a control protocol to negotiate the type of transport
protocol to use for the stream. RTSP is used by a viewing client to start a unicast session.
o
User Datagram Protocol (UDP):
UDP is a communications protocol that offers limited service for exchanging
data in a network that 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.
o
Unicasting:
Unicasting is communication between a single sender and a single receiver over a network. This
means that the video stream goes independently to each user and each user gets a personal stream. A
benefit of unicasting is if one stream fails it only affects one user.
o
Multicasting:
Multicasting is a bandwidth-conserving technology that reduces bandwidth usage by
simultaneously delivering a single stream of information to multiple network recipients. This technology is
used primarily on delimited networks (intranets) as each user needs an uninterrupted data flow and should
not rely on network routers.
