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 Set Top Box that is 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.  
 
The DT-Board also incorporates the OpenCable interface for use with a CableCard. 
This tuner allows the reception of 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.  
 
The DT board contains the host identification number and stores the identification 
number of the CableCard.
