Visix customers asked us for a way to show HD-quality video
on their displays within their digital signage layouts. In answer to your
requests, AxisTV and Announce now both support QAM video overlay by leveraging
Windows 7 media players and our Video Window Tuner Card.
QAM (quadrature amplitude modulation) is
the format by which digital cable channels are encoded and transmitted via
cable television providers. We chose to leverage QAM overlay because it
provides a cost-effective method for tuning unencrypted channels in the U.S.
The most popular use of this feature will
be for our clients wanting to show cable TV channels within their digital
signage layouts. There are two types of channels you may want to show:
1)
Cleared QAM (unencrypted channels such as
basic cable, and
2)
Encrypted video (encrypted channels,
satellite feeds, etc.)
We have two QAM options, depending on the application: See Diagram
1)
Cleared QAM channels only:
Take your cable feed from the wall into a Visix small-form factor or rack mount
media player using Windows 7 and the VWOT (video window tuner) to show cleared
QAM channels within your digital signage layout.
·
The number of cleared QAM channels your cable
provider supplies is limited. You must check with your cable provider to
determine which channels are unencrypted.
2)
Satellite or other encrypted sources:
Take the video source into a QAM Modulator, then into a Visix small-form factor
or rack mount media player using Windows 7 and the VWOT (video window tuner).
We realize that there are some proponents of HDMI out there,
but HDMI doesn’t allow you to plug your cable feed into a media player or a PC due
to content controls from cable providers (HDCP).
QAM video overlay is available as of AxisTV v.7.2.0.1 and
Announce v.1.3 releases. For more information about the most recent releases
and to request a software update, please visit http://www.visix.com/software_updates.html.
Want to know more? We’re hosting a complimentary 30-minute
webinar on Wednesday, February 29 at 2:00PM EST. We’ll go into more technical
detail about QAM and how it can work in your environment, as well as host an
open Q&A session.
