Features
• Streams DVI, RGB, HDTV, and video signals with audio over IP networks.
• Inputs — DVI-D with loop-through; universal 15-pin HD input with loop-through for
RGB, HD component video, S-video, or composite video; BNCs with loop-throughs for
component video, S-video, or composite video.
• Outputs — Ethernet for streaming H.264 / MPEG-4 AVC encoded video.
• Standards-based H.264 / MPEG-4 AVC video compression — The SME100
employs high, main, and baseline profiles of the H.264 / MPEG-4 AVC compression
standard, which are compatible with many different platforms including desktop and
laptop PCs. SME100 streams can easily be viewed on PCs using web browsers and
software media players such as VLC media player
®
, QuickTime
®
, and the Extron SMP.
• Integrated three-input AV switcher — The SME100 accepts commonly used
video signal formats together with stereo audio, from DVI to analog RGB and
composite video. The universal video input can accept a variety of analog formats and
automatically detect between them.
• Buffered input loop-throughs for video and audio — Each input has a buffered
loop-through. This allows the SME100 to be integrated into a new or legacy system
without the need for additional AV equipment (such as distribution amplifiers).
• Supports input signal resolutions up to 1920x1200, including HDTV 1080p/60
The SME100 supports a wide range of input resolutions, from standard definition up to
the high resolutions commonly used for computer-video and HDTV.
• 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.
• Auto input format detection — The universal video input on the SME100 can detect
the incoming signal format and automatically reconfigure itself to provide the appropriate
decoding and signal processing. This feature can reduce the number of required
outputs for a matrix switcher, lowering system cost while improving manageability.
• Auto-Image™ setup — When activated, the SME100 automatically analyzes the
incoming video signal and then automatically adjusts sizing, centering, and filtering to
optimize image quality. This can save time and effort when fine tuning displayed images.
• Selectable streaming output resolutions from 166x120 to 1024x768, and
HDTV 720p/30 and 1080p/30 — Available output rates include various resolutions
optimized for mobile or compact devices, or computer-video (from 166x120 to
1024x768, and HDTV 720p and 1080p). Frame rates can be adjusted from 30 fps
down to 1 fps.
• AAC audio encoding — Variable audio compression is available to support different
streaming bit rate requirements.
• Encoding quality controls — Several user controls are available to adjust encoding
quality including video resolution, video bit rate, frame rate, constant or variable bit rate
control, GOP length, and audio bit rate.
• Presets for quick recall of profiles based on target resolution or bit rates — The
SME100 provides 16 presets for saving encoder control settings. This allows a user to
quickly switch between various encoder profiles based on resolution or bit rates. Nine
presets on the SME100 HD and six presets on the SME100 SD are predefined for
common streaming applications.
