Compliant with SMPTE 259M/292M/424M (Level A) / 425M

Closed Captioning embedded in VANC of SD or HD SDI signals per SMPTE 334-1 or Captions found in Line 21 of SD signals per EIA-608 are embedded in the essence of H.264 as SEI NAL Units (CEA-608) as per SCTE 128-1 specification.

Video Output


Video Output Resolutions

Preview output of video input signal. Preview output is available when source is SDI or HDMI.

0 frame latency passthrough of SDI Input signal. Output is a clean distribution of SDI incoming signal. Hardware bypass relay present in SDI signal path is "closed" on power failure.

When input is an SD-SDI resolution, the HDMI preview output will show video window boxed on an HD output.

Audio Input

Processes the first two channels of audio embedded in HDMI or SDI input signals.

Unbalanced analog stereo input via 1/8” (3.5mm) jack.

Line Level

Audio Output

Passthrough of 8 channel of embedded audio channels in HDMI and SDI signals.

Unbalanced analog stereo output via 1/8” (3.5mm) jack—passthrough of input.

Line Level

Note that all outputs are active regardless of audio and video input selection.

Confidence Preview

1x SDI


Maximum resolution: 1920x1080

Color Space and Chroma Sub-Sampling

4:2:0 (8-bit)

Video and Audio Processing
Frame Synchronization

The Monarch HDX contains frame synchronization circuitry designed to compensate for disruptions of the input signal. This circuitry is in place for both SDI and HDMI inputs. Streaming and recording operations will proceed cleanly with repeated or dropped frames.

Video Scaling

High Quality multi-tap 10 bit Down Scaler and De-Interlacer
Available for both streaming and recording operations

Audio Encoding Format


Audio Sampling Frequency

32 kHz

44.1 kHz

48 kHz

Audio Bitrates

Range from 32 kbps to 256 kbps
Note that audio codec settings are applied to both encoders.

Video Encoding Formats

H.264/MPEG-4 Part 10 (AVC)

Encoding Profiles

Baseline (BP)

Main (MP)

High (HiP)

Encoder Bitrates Range

Single Encoder - Streaming mode: 20 Mbps

Single Encoder - Recording mode: 30 Mbps

Dual Encoder - Maximum of 10 Mbps for streaming channels

Maximum of 30 Mbps combined for both channels

Encoding Rate Control

Average max/min data rate controls

Deblocking Filter

Selectable frame rates

GOP Size

Variable bitrate support 

Encoding Level

Up to 4.2

Recording Locations

2x USB 2.0*

1x SD card slot**

Network mapped drive***

* Support for NTFS (3.1) and FAT32 file system. The Monarch HDX will support writing to USB3 devices at USB2 speeds. Also note, there is a very high variability in the performance capabilities of “thumb” drives (even USB3 versions). Many are optimized for “read” operations while the Monarch HDX requires sustained “write” capabilities. For best results, Matrox recommends using powered USB drives. If small portable media is required, SD cards may be more suitable.

** Supports SD and SDHC cards. Only NTFS formatted SDXC cards are supported. (Class 10 highly recommended).

*** Support for writing to shared folders in computers found on a network using Windows Share protocols (suitable for Windows system) as well as NFS protocols (suitable for Mac and Linux systems).

Recording Lengths

Maximum file length of 300 minutes—irrespective of storage type used. File splitting feature allows a user to record continuously for long periods by defining file segment sizes. The Monarch appliance will create these sequential file segments over the course of the recording operation without losing a single frame of video. File segment can have a length of 1 to 300 minutes.

Network Standard

IP Addressing


DHCP (default) and static IP

Streaming Protocols

Unicast and Multi Unicast (number of clients may vary from 3 to 10)
