Extron electronics SMP 351 User Manual

General Product Overview
Input
The SMP 351 can accept up to three HDMI inputs, one component or composite video
input. The SMP 351 3G-SDI is identical to the SMP 351 except that it includes the 3G/HD/
SDI input (input 5). Both models accept digital audio embedded on HDMI signals or analog
audio input via captive screw connectors.
• Inputs 1 (HDMI) and 2 (HDMI) are grouped as channel A.
• Inputs 3 (component or composite video), 4 (HDMI) and optional input 5 (3G/HD/SDI)
are grouped as channel B.
• One video and one audio input can be selected and active per input channel.
Encoding and Output
Signals from the two input channels, a background image, and metadata (descriptive
information about data content) are combined in a user-configurable layout and encoded
into streams. The SMP351 can encode a high quality stream (for recording and optional
live streaming) and also encode a lower resolution stream (for preview within its embedded
Web pages and optional live streaming). See the Encoder Settings and Layout Presets
Overview on page90 for a comparison of the two encoding types (archive and
confidence). The video output can be scaled and its aspect ratio modified. The SMP351
also outputs high quality encoded HDMI video with embedded audio on a single output for
display on any HDMI display, supporting resolutions up to 1920x1080 at 60 Hz.
