•
SAP
(Session Announcement Protocol – RFC 2974) — Allows decoders to discover
and list streams (sessions) available on the local network. Specifically, displays a list of
currently active and compatible multicast streams on the web interface browser page,
allowing a user to select and load, and begin decoding and displaying, any of those
streams without requiring any further information.
•
SDP
(Session Description Protocol – RFC 4145 and 4566) — Allows RTSP
initialization of the Quantum Ultra IP card using a locally stored SDP file to function as
a browser helper application. In practice, the IP card may use the DESCRIBE method
to initialize RTSP. Also used to encapsulate the data for SAP.
Transport layer protocols:
•
UDP
(User Datagram Protocol) — For multicast and possible control and monitoring
feature support
•
TCP
(Transport Control Protocol) — For RTSP and HTTP support
Internet layer protocols:
•
ICMP
(Internet Control Message Protocol) — Required to support ping echo requests
and replies
•
IGMP
(Internet Group Management Protocol) — Required for IP multicast stream
support
Protocol combinations supported from Extron SME 100 and future Extron
streaming products:
•
UDP-TS
— Single program MPEG-2 transport stream (SPTS) unicast or multicast
•
Unicast RTP
— Native (elementary audio and video streams). Single program
MPEG-2 transport stream (SPTS, RTP-TS)
•
Multicast RTP over UDP
— Native (elementary audio and video streams). Single
program MPEG-2 transport stream (SPTS, RTP-TS).
•
Unicast RTP over RTSP
(RTP and RTSP interleaved over TCP) — Used for
on-demand video where RTP is interleaved with RTSP over a TCP connection to
navigate fire walls that block UDP.
•
Unicast RTP over RTSP over HTTP
(RTP and RTSP interleaved over TCP on
port 80) — Used where RTP is interleaved with RTSP over HTTP and is used to
navigate fire walls that allow HTTP (ports 80 or 8080 are open).
Outputs
The Quantum Ultra HDMI and DTP output cards integrate all inputs to be displayed in a
layout that you define using the control software (see the
VCS Help File
for information on
using the program to set up displays). They also provide up-scaling of sources.
•
HDMI output cards
— These cards provide the final output to a display device.
They have four female HDMI A connectors, numbered 1 through 4 from left to right.
Connect up to four HDMI or DVI (with an appropriate adapter) displays to these cards.
