Extron Electronics SME 100 User Guide - Manual (Page 12)

• Embedded preview window — The SME 100 provides an intuitive interface that
contains an embedded video window used for viewing live streams.
• Embedded web page HTML — The SME 100 interface includes basic HTML code
that can be copied and pasted to quickly create web pages for viewing SME 100 AV
streams on networked PCs.
• RS-232 control port — Using serial commands, the SME 100 can be controlled and
configured via DataViewer or integrated into a control system. Extron products use the
Simple Instruction Set (SIS™) command protocol, a set of basic ASCII code commands
that allow for quick and easy programming via RS-232.
• Rack-mountable 1U, full rack width metal enclosure
• Internal universal power supply — The 100-240 VAC, 50/60 Hz, international power
supply provides worldwide power compatibility.
• Maximum Transmission Unit (MTU) — Can be adjusted to fit network system
requirements.
• Session Announcement Protocol (SAP) — Provides the ability to announce the
broadcast to the network making it easier for the end user to discover the live stream.
Compatible with many third-party H.264 devices including set-top box decoders.
• Push and pull streaming session management — The flexibility to manage push
and pull streaming sessions allows the SME 100 to be compatible with a variety of
H.264 devices and streaming applications.
• Pull streaming transport protocols — RTP/RTSP, interleaved RTSP, and HTTP
tunneled streaming transport protocols may be used based on various network
conditions or to aid in firewall navigation.
• Push streaming transport protocols — Native RTP and MPEG-2 transport streams
may be used with unicast or multicast streaming applications. Streams can be
transported on UDP or RTP depending on network conditions.
• Streaming transport protocol options — Allows the SME 100 to be used with a
variety of network configurations; provides compatibility with many third party devices
• H.264 compression profiles and level selection — The H.264 baseline, main, or
high profiles can be used at levels 5, 4.x, or 3.x, providing the ability to optimize video
bit rate and complex coding that can be used with specific types of decoding devices
(such as set-top box decoders).
• Stream unicast or multicast while applying pull or push session management
— The SME 100 can manage streaming sessions using either push or pull
configurations, which allows it to be used with a variety of decoding devices and media
servers. Pull configurations apply the Real Time Streaming Protocol (RTSP). Push
configurations use the Session Announcement Protocol (SAP) and Session Description
Protocol (SDP). SAP and SDP protocols are able to automatically identify and configure
decoding devices to decode AV streams in unicast or multicast applications.
• Compatible with set-top box decoders — The SME 100 is compatible with set-top
box decoders which require the use of MPEG-2 transport streamsand push streaming
session management using SAP and SDP.
• EIA-608B closed captioning support — Text or prepared messaging may be
streamed with live AV content using decoders or media players that support the
EIA-608B closed captioning for standard definition video.
• Network traffic prioritization — SME 100 streaming data can be marked with a
request for higher service priority from compatible routers, offering a higher Quality of
Service (QoS) during constrained network conditions.
