near-instantaneous without laborious reboots
of the hardware.
The current firmware doesn’t seem to support B-frame encoding (available in Main and
High profiles of AVC/H.264) very well, at least
for typical RTMP pushes to streaming media
servers. Lastly, the output audio sampling rate
is fixed at 48KHz; there is no option for using a
different output sampling rate.
MATROX MONARCH HDX ($1,995)
I’ve been familiar with Matrox’s Monarch
line for quite some time now, and have used
the HDMI-only version of the Monarch HDX for
many engagements. Matrox has several Mon-
arch models. The HDX (Figure 3) came in just
below the $2k price point, and it features both
SDI and HDMI inputs. Like the AJA HELO, the
Monarch HDX is designed to be installed in
a more semi-permanent A/V rack system for
routine and regular streaming in a venue.
On the Monarch HDX’s back panel, you’ll
find all A/V inputs and a plug for the unit’s power cable. On the front, you’ll find controls for
starting and stopping streaming, as well as two
USB ports and one SD slot for recording media.
Discoverability of the Monarch HDX requires
the Matrox Monarch HDX Utils application,
which reports the IP address, device name, serial number, firmware version, and status of
each Monarch HDX on your network. Once you
know the IP address of the Monarch HDX, you
can use that address in a web browser to log in
and configure your streams (Figure 4).
The Monarch HDX, like the AJA HELO, can
only be configured with a web browser and not
with a built-in menu display and option controls.
The Monarch’s web interface is slower to update the
unit with new settings than
the HELO’s. The HDX is the
only unit tested that has an
audible fan running anytime the unit is powered on.
OSPREY TALON G2
This roundup provided
my first opportunity to test
an Osprey H.264 encoder,
Because the Talon G2 has a built-in touch-screen that displays the unit’s acquired IP address after booting, there’s no need for a discovery tool to configure the device. The Talon
