1 SME-1901 and SME-1911 Monitoring Streaming Media Encoders
1.1 Introduction
Designed for multi-format video/audio over IP in television facilities, the SME-1901 and SME-1911 are compact H.264
streaming encoders with 3G/HD/SD SDI input and optional Fiber connectivity; the SME-1901 also incorporates a 1x6
SDI distribution amplifier.
Two High Profile H.264 streams are generated simultaneously from the SDI input. The Main high resolution stream is
ideal for in-house IPTV applications while the low resolution Proxy targets streaming and display within a control
system network. Both streams are full frame rate and provide high efficiency compression.
It operates with a wide range of decoders, and offers exceptional space and power efficiency with up to 20 dual
stream encoders in a Densité 3 frame configuration. The SME-1901/SME-1911 are ideal for monitoring of core routers
over IP, with the SME-1901 also providing “fan-in” and “fan-out” distribution amplification.

2 Installation
2.1 Installation of Rear Connector Panels
Grass Valley Densité-series cards are each associated with a rear connector panel, which must be installed in the
Densité frame before the card can be inserted.
The SME-1901/1911 card is sized to fit into Grass Valley’s Densité-2 frame, but can be ordered with an extender to fit
the taller Densité-3 frame. Rear panels are available for each frame type. SME-1901 and SME-1911 cards use
different rear panels, as the SME-1901 rears include the DA outputs and optional bypass relay which are not included
in the SME-1911.
SME-1901 rear connector panels:
•SME-1901-DRP Densité-2 - Double-slot-width panel with 1x6 DA
•SME-1901-3SRP Densité-3 - Single-slot-width panel with 1x5 DA
•SME-1901-3SRP-R Densité-3 - Single-slot-width panel with 1x5 DA and bypass relay
•SME-1901-3SRP-F Densité-3 - Single-slot-width panel with 1x4 DA and fiber I/O support
•SME-1901-3SRP-D-F Densité-3 - Single-slot-width panel with 1x6 DA, DIN connectors and fiber I/O support
SME-1911 rear connector panels:
•SME-1911-DRP Densité-2 - Double-slot-width panel
•SME-1911-3SRP Densité-3 - Single-slot-width panel
•SME-1911-3SRP-F Densité-3 - Single-slot-width panel with fiber I/O support
See section 2.3 for details of the signal connections available on each of these connector panel types.
Rear panels are not interchangeable between the SME-1901 and the SME-1911
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
•To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the connectors
apart, then use the handle to pull the card straight out of the slot.

To install the connector panel (Densité 2 and Densité 3 frames):
1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.
2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the
captive screw(s) at the bottom.
3. Position the new panel and secure it in place with the captive screw(s) at the bottom.
2.2 Card Installation
Once a matching rear connector panel has been installed, install the SME-1901/1911 card as follows:
1. Open the front panel of the frame.
2. Slide the SME-1901/1911 card into the slot and push gently on the handle to seat the connectors.
•For the double-slot-width rear panels used in Densité 2 frames, insert the card into the right-most slot, as
seen from the front of the frame. If the card is inserted into the wrong slot, the status LED on the front of the
card will flash red. The card will not be damaged.
3. Close the front panel of the frame.

3 User Interface
3.1 Control options
The SME-1901/1911 can be controlled in three different ways:
•The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust a
basic set of parameters (see section 4).
•Grass Valley’s iControl system can be used to access the card’s operating parameters from a remote computer,
using a convenient graphical user interface (GUI) (see section 5).
•Grass Valley’s RCP-200 panel (consult factory for availability).
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the SME-1901/1911, and is visible through the front
access door of the DENSITÉ frame. This multi-color LED indicates the status of the SME-1901 by color, and by
flashing/steady illumination.
The chart shows how the various error conditions that can be flagged on the SME-1901/1911 affect the LED state.
•If a cell is gray, the error condition cannot cause the LED to assume that state.
•If more than one LED state is possible for a particular error condition, the state is configurable.
See Section 5.10 for details.
•The factory default state is shown by a 
The LED will always show the most
severe detected error status that it is
configured to display, and in the chart
error severity increases from left to
right, with green representing no
error/disabled, and flashing red the
most severe error.
If the LED is Flashing Yellow, it
means that the card is selected for
local control using the Densité frame’s
control panel. See Section 4 for
details.

4 Local control using the Densité frame control panel
4.1 Overview
Push the SELECT button on the SME-1901/1911 card
edge (see Section 1.4) to assign the local control panel
to operate the SME-1901/1911. Use the control panel
buttons to navigate through the menu, as described
below.
All of the cards installed in a Densité frame are
connected to the frame’s controller card, which handles
all interaction between the cards and the outside world.
There are no operating controls located on the cards
themselves. The controller supports remote operation
via its Ethernet ports, and local operation using its
integrated control panel.
The local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed is
located in the front center of the frame, positioned in front of the power supplies. The panel consists of a display unit
capable of displaying two lines of text, each 16 characters in length, and five pushbuttons.
The panel is assigned to operate any card in the frame by pushing the SELECT button on the front edge of that card.
•Pushing the CONTROLLER button on the control panel selects the Controller card itself.
•The STATUS LED on the selected card flashes yellow.
The local control panel displays a menu that can be navigated using the four pushbuttons located beside the display.
The functionality of the pushbuttons is as follows:
[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button once
enables modification of the value using the [+] and [–] buttons; a second push confirms the new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the
parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not
exit the menu system. To exit, re-push the [SELECT] button for the card being controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS LED reverts to its normal operating mode.
4.2 Menu for local control
The SME-1901/1911 has operating parameters which may be adjusted locally at the controller card interface.
•Press the SELECT button on the SME-1901 front card edge to assign the Densité frame’s local control panel
to the SME-1901/1911.

5.6 Codec Config panel
This panel controls the output coding process.
Audio Codec
Use the radio buttons to select whether the output audio
channels are those selected in the Left and Right pulldowns
(in the range 1 to 16), or the output of the downmixer (see
the Audio Processing panel).
Audio Codec - Encoding
Use the pulldown to select the audio encoding scheme:
•MPEG 1 L2@ 256 kbps
•AAC-LC @ 128 kbps
.
Video Codec – Force progressive mode encoding
The video encoder normally defaults to interlaced mode for
interlaced formats and progressive mode for progressive
formats. Some decoders cannot decode a stream encoded
in interlaced mode. If this is the case, Force Progressive
Mode Encoding should be checked. Forcing this mode for
interlaced formats may cause artifacts, particularly in film-
originated content.
Test Pattern (Streaming output only)
The pulldown allows the user to select an internally-generated test signal to replace the program signal at the SME-
1901/1911 streaming output.
OFF: the program signal appears at the output, and test signals are OFF
Color Bars and Tone: sends a 75% color bar test pattern (100% white), along with audio test tones (a
continuous tone on right channel with pulsed tone on left channel) to the SME-1901/1911 output.
Lip Sync: sends a special test signal comprising color bars and tone plus a detectable element that is used to
align audio-video delays in a processing path.
•The special test signal consists of 75% color bars within which a white square is inserted every 4 seconds for
a duration of 10 frames. Simultaneously with the beginning of the first field of video containing the white
square, the 16 embedded audio channels are pulsed with a tone lasting 250 ms.
