Encoding quality controls

Several user controls are available to

adjust AV encoding quality, including

video resolution, video bit rate, frame rate,

constant or variable bit rate control, GOP

length, and audio bit rate.

Streaming presets for quick

recall of streaming proﬁles

based on target resolution or

bit rates

The SME100 provides 16 presets for

saving encoder control settings, so the

user can quickly switch between various

streaming proﬁles based on resolution or bit

rates. Eight of these presets are predeﬁned

for common streaming applications.

Glitch-free switching

Switching is glitch-free with a cut transition.

Presentations are enhanced by eliminating

distracting visual jumps, glitches, and

distortion commonly experienced when

switching between computer and video

sources.

Internal test patterns for

calibration and setup

The SME 100 offers 15 test patterns as

well as on-screen display - OSD data

overlay including Time Stamp, average bit

rate, frame rate, time and date and system

information to aid in calibration and setup of

the encoder.

AAC audio encoding

Variable audio compression is available

to support different streaming bit rate

requirements.

User-adjustable audio delay

Audio delay can be adjusted to adapt

the streamed output to different network

conditions.

Ethernet monitoring

and control

The SME 100 is controllable over

the Ethernet connection supporting

conﬁguration and real-time management

from Extron or third party control systems.

Embedded preview window

The SME100 provides an intuitive Web

interface with an embedded video window

to view the live stream as well as source

input and encoding adjustments.

Embedded Web page HTML

The SME100 Web 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 the

Extron Windows

-based control program,

or integrated into a control system. Extron

products use the SIS™ - Simple Instruction

Set command protocol, a set of basic ASCII

code commands that allow for quick and

easy programming.

Power Save Mode

The SME100 can be set to automatically

mute video and sync output to the display

device when no active input signal is

detected. This allows a display, connected

to the input loop-throughs, to automatically

enter into standby mode to save energy

and enhance lamp or panel life.

Low Power Mode

The SME 100 can be conﬁgured to operate

in a low power mode when an active signal

input is not present.

Standards-based H.264

/ MPEG-4 AVC video

compression

The SME100 employs the High Proﬁle of

the H.264 / MPEG-4 AVC compression

standard which provides high quality

encoding, and can be interfaced with

compatible media players or decoded on

PCs using software media players such as

VLC or QuickTime.

DVI, RGB, HDTV, and standard

deﬁnition video upscaling and

downscaling

DVI, RGB computer-video, high deﬁnition

video, and standard deﬁnition video sources

can all be scaled to a range of deﬁned

streaming resolutions. The SME100

features an advanced scaling engine that

preserves image quality when upscaling or

downscaling an input signal.

Available in two models

streaming at SD or HD

resolutions

The SME100 is available in two models: the

SME100HD and the SME100SD, which

stream at various resolutions optimized

for speciﬁc displays or applications.

The SME100SD streams at selectable

resolutions from 166x120 to 720x576.

The SME100HD streams at selectable

resolutions from 166x120 up to HDTV

1080p/30. Frame rates can be adjusted

from 30fps to 1fps.

Aspect ratio control

The aspect ratio of the streamed output

can be controlled by selecting a FILL mode,

which provides a full screen output, or

a FOLLOW mode, which preserves the

original aspect ratio of the input signal.

The SME 100 offers ﬂexible control, scaling, and encoding capability to

support a wide range of streaming devices and destinations.
