About this Guide
This guide contains installation, configuration, and operating information for the SMP351,
SMP 351 3G-SDI, SMP 352, and SMP 352 3G-SDI. In this guide:
• “SMP 300 Series”, “SMP models”, or “the SMP” refer to the SMP 351,
SMP3513G-SDI, SMP 352, SMP 352 3G-SDI models.
• “Codec” refers to the H.264 / MPEG-4 AVC codec.
• “Stream” can refer to audio, video, or both that is transmitted by the SMP.
• “UI” and “web UI” refer to the Web-based User Interface.
About the SMP300 Series
The Extron SMP 300 Series is a compact, high performance H.264 recording and streaming
processor that provides the ability to record a presentation and output an HDMI signal to a
local display, and, if needed, stream the AV content live while recording.
Six versions of the SMPmodels, with varying internal file storage capacity, are available:
• SMP351 (80 GB and 400 GB)
• SMP351 3G-SDI (80 GB and 400 GB)
• SMP 352 (400 GB)
• SMP 352 3G-SDI (400 GB)
NOTE: The SMP models have similar front and rear panel features and function exactly
the same. The SMP3513G-SDI and SMP 352 3G-SDI support a 3G-SDI video input.
Figure 1 on the next page shows an SMP 351 application that utilizes Channel A HDMI and
an audio loop-out for local display of the computer input. The presentation is then streamed
to an SMD 101.
Figure 2 on the next page shows a typical SMP300 Series application featuring a
computer input with embedded audio, an SDI camera input, and a wireless microphone for
audio. The presentation is streamed to a SMD 101 and the SMP 352 records both channels
and publishes to the Entwine EMP and the Kaltura cloud hosted service. The SMP 351
models can be upgraded to support SMP 352 features through a LinkLicense upgrade.

General Product Overview
Input
The SMP 300 Series can accept up to three HDMI inputs and one component or
composite video input. The SMP 351 3G-SDI and SMP 352 3G-SDI are identical to the
SMP 351 and SMP 352 with the addition of the 3G/HD/SDI input (input 5). All models
accept digital audio embedded on HDMI signals or analog audio input via captive screw
connectors.
• Input 1 (HDMI) and input 2 (HDMI) are grouped as channel A.
• Input 3 (component or composite video), input 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
The SMP models support multiple simultaneous stream encoders. Additionally, the
SMP352 supports channel A and channel B archive streaming. Each can have a different
resolution, frame rate, bit rate, and independent streaming protocol methods. The output
defaults to both record and stream the selected input.
• Archive (channel A and channel B in dual channel mode) — Highest quality for both
recording and streaming.
• Channel A default: Pull, unicast RTP/UDP
• Channel B default: Not enabled
• Confidence — For streaming only (default: Pull, unicast RTP/UDP).
In composite mode, 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300 Series has two encoding types (see
Encoding & Layout on page75). The SMP can encode on archive encoding mode for
high quality streams (for recording and optional live streaming), and on Confidence encoding
mode for lower resolution streams (for preview within its embedded web pages and optional
live streaming). The video output can be scaled and its aspect ratio modified. The SMP300
Series 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.
NOTE: Signal flow for both channel A and channel B can be followed from input to
output in the block diagram in figure3 on the next page.

Control Options
The SMP300 Series can be controlled using the following:
• Front panel menus and controls
• Simple Instruction Set (SIS) commands sent over Ethernet via the LAN connection,
RS-232 via the rear panel Remote captive screw connector, or USB via the front panel
Config port.
• SMP 300 Series embedded web pages over Ethernet connection.
• USB mouse and keyboard ports provide direct connection of a keyboard and mouse to
permit the use of an internal browser client. This allows limited web page configuration
of the network settings for the device.
• Four digital I/O ports can be configured (using a FlexOS application) as digital inputs
to receive status from other devices like push-button controls and projector lifts.
Alternatively, they can be configured as digital outputs to drive LEDs or devices that
accept a TTL input signal for local device control.
• The optional Extron RCP 101 remote control panel connected through either the
keyboard or mouse port on the rear panel.
Recordings
The core function of the SMP300 Series is to create recording files from connected audio
and video input sources.
Start a recording
Recordings are initiated in one of several ways:
• Unscheduled (adhoc) recordings — Require manual configuration. To use this
method, perform one of the following:
• Press the Record ( ) button on the front panel of the SMP300 Series or
RCP101 remote control panel
• Click the Record ( ) button in the AV Controls panel of the SMP300 Series
embedded web pages (see Start an AdHoc Recording on page59) and set
the options in the Start an Adhoc Recording window
• Tap a control button on a configured touchpanel (such a an Extron TLPPro Series
touchpanel with a custom script).
• Scheduled recordings — Recordings start automatically at the date and time
specified in a calendar schedule. Schedules can be imported on a one-time basis, on
a periodic basis (updated on a fixed interval), or an ongoing basis (using a compatible
scheduling server such as Opencast or Microsoft Exchange) (see System Settings on
page83 for details on how to set up recording schedules).
Make a recording
The SMP300 Series creates recordings by:
• Composite mode — Scaling and arranging the content from one or both AV
input channel A and channel B and the optional background .png file as defined by
the selected layout preset (see Layout presets (for composite mode only) on
page78)
• Dual mode — Scaling channel A and channel B in full screen with no background and
no metadata.

SMP 300 Series • Introduction

• Encoding the content into up to three encoding streams (two encoding streams [archive
and confidence] in composite mode, three encoding streams [ChA archive, ChB archive
and confidence] in dual channel mode (see Encoding & Layout on page75).
• SMP 351 models encode the content and layout into two encoding streams, archive
and confidence.
• SMP 352 models and SMP 351 models, with LinkLicense, encode the content and
layout into three encoder streams that include archive channel A, archive channel B,
and confidence.
• Creating a set of files — One or more .m4v or .mp4 files and other files containing
metadata, thumbnail images, and optional chapter markers. These files are stored either
within the unit (the internal, default location), or on an optional USB drive (see Encoding
& Layout for instructions on how to set the default recording storage location).
The SMP300 Series creates a set of the same types of files for every recording, regardless
of how a recording is initiated. Default file names are specified within the System Settings
page (see Setting the Default Recording Media on page84 for details).
Output and share recordings
Recording files can be saved in the SMP300 Series internal memory and on an optional
connected USB drive. Recordings stored internally (not on a USB drive) can also be
automatically uploaded to a network server folder.
NOTES:
• When integrated with an Opencast, Entwine, or Kaltura, server, both adhoc and
scheduled recordings are automatically uploaded to the server location defined
during the scheduling setup.
• To upload recordings for other scheduling or integration methods, specify a
publishing destination during system setup (FTP, SFTP, or CIFS/Windows Net Share
server folder).
Uploading recordings to a server allows the user to archive or share files with others who are
authorized to access that folder or to use tools such as Entwine EMP.
• Entwine EMP is a tightly-integrated end-to-end software solution that facilitates the
capture, management, and playback of media files from meetings, lectures, and other
live events. Current, previously recorded, or archived media files can be added to
Entwine EMP, making everything accessible from a single point. Entwine EMP ensures
recordings with metadata are packaged for playback within the player environment.
