TS/UDP — (Unicast or multicast) An MPEG-2 transport stream containing the
•
elementary streams for the audio and video. It is sent using UDP packets.
TS/RTP — (Unicast or multicast) Transport stream that is sent using RTP/UDP. RTP
•
provides sequencing, timing, and control information; if the sequencing information
is reordered by the network, RTP reorganizes and processes the information in the
correct order. UDP would process the sequencing information out of order, making RTP
performance better on larger, many hop networks.
Unicast — Sending messages from one device to a single network destination on a
network. Having
clients of a unicast stream requires the server to produce
N
unicast data.
User Datagram Protocol (UDP) — A connectionless, transport layer protocol that sends
packets (datagrams) across networks using "best-effort" delivery. It is a relatively simple
protocol that does not include handshaking.
Variable Bit Rate (VBR) — A compression scheme that adjusts the output bit rate around
a specified target bit rate depending on the audio or image complexity. More bandwidth is
used when the video frame is more complex, and less bandwidth is used when the video
frame is simple.
