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.

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
Overview
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.
