The DV board processes HDMI or DVI input signals. The HDMI IF receiver converts the
digital signal into parallel Y, U, V data and outputs it to the DG board for video selection
and processing.
GP8HD series plasma panels incorporate a tuner designed to receive NTSC and ATSC
television broadcast. It is also used to receive QAM cable television transmission. It is a
hybrid tuner that processes NTSC and ATSC terrestrial broadcast for reproduction on
the TV screen.
This tuner allows the reception of basic Digital Cable television without the use of a set-
top-box.
The DT board contains an Optical Audio Out jack for use with a Dolby Digital decoder
and a multi-channel amplifier. When a digital channel is selected, the output from the
Digital Audio Out jack is Dolby Digital. The same jack outputs PCM (Pulse Code
Modulation) when any other signal source is selected.
An SD card slot is also included in the DT board. As the OpenCable service changes,
the firmware information located in the DT board may be upgraded by using an SD
card.
Analog Television signals are output to the H board and selected like any other source.
Digital television signals (Y, Pb, Pr) are output to the DG board for video selection and
processing.
