Cable Headend Equipment
years DVC developed a range of products in this field, working with
a number of different, but related companies.
In response to customer
requirements, DVC's innovation and custom development capabilities
allowed higher levels of integration, allowing more and more
ad-insertion functionality in a smaller and smaller space.
Space is always at a premium within the headend. And anything to
simplify cabling, installation and maintenance requirements makes
for real savings for Cable Operators.
Customers for DVC's Cable TV
products include all the major MSOs in the USA and Canada, as well
as international customers, in the UK, Europe, Caribbean and South
America. With more than
30,000 channels of ad-insertion playback in service in 24 hour operation, there is no doubt of the
products' stability and continued effectiveness.

image shows the DVC MDS-420 installed in a rack with a Compaq AlphaServer
using RAID to store commercials as data files.
Power Supply (UPS) is mounted in the base of the rack.
Each MDS-420 unit supports four channels of
digital-into-analog insertion. Installed as a cable head-end, this
rack would allow 40 separate channels to carry local advertising.
Equipment similar to this is installed in about
3000 cable head-ends throughout the United States
for insertion of local commercials.
DTMF Trigger IP sender
Extending the product range into Digital
Program Insertion (DPI) DVC developed a custom product for use at
Time Warner Cable. DTMF tones from the analog satellite receivers
can be used to define the timing of local advertising inserted
directly into the digital feed from the server.
Digital Video Processing IP gateway
DVC has developed a highly flexible platform
capable of processing at least 16 video streams. It has 2x GigE,
16xDVB/ASI inputs and internally up to 16 DSPs which can be combined
to scale, insert logos, time delay, stream switch, de-multiplex and
re-multiplex multi-program streams.
