DHDP Series
Easily Deliver Digital & High
Definition Programming
Blonder Tongue’s Digital High Definition Processor (DHDP)
Series gives cable television operators the ability to easily
deliver digital & high definition programming from 8 VSB off-
air sources to customers over existing cable systems.
The DHDP series is a two-part system that receives any high definition or digi-
tal signal and processes it to any available 6 MHz channel in the 54-806 MHz
frequency range. The unit does not modify any of the data stream information
throughout the process guaranteeing compatibility with many consumer
decoders. Achieving the highest level of signal purity, the DHDP features triple
SAW filtering that results in extremely high adjacent channel rejection. Plus,
advanced AGC circuitry ensures consistent output signal fidelity. All modules are
housed in Blonder Tongue’s advanced die-cast micro housing and compatible
with standard micro-modulator racks & power supplies.
With DHDP Series Converters, an operator uses an off-air antenna to receive
the digital & high definition programming from local broadcast sources. These
signals, currently found in the UHF band, are transmitted in 8 Vestigial Side
Band (8 VSB) format. The 8 VSB signal is received by the DHDC-D, converted
to IF and then fed to the DHDC-U. The DHDC-U then upconverts the signal to
any available channel, including on-channel if desired, for distribution on the
existing cable system. The signal can then be viewed at the customers’ homes
with any HDTV-capable television or a standard television with an external
HDTV receiver.
