Dg Board Block Diagram - Panasonic TH-37PX50U Technical Manual

The DT board contains the host identification number and stores the POD identification
number of the cable service provider.
It also processes the JPEG data of the SD and PC cards used for viewing pictures.
Photoviewer data from the G and GS boards are input to the DT board via the
connectors DT10 and DT05. The JPEG data is converted to analog luminance and
chrominance signals and output to the DG board.

The main function of the DG board is to process all incoming video signals.
The ATSC interface (DT board) processes the ATSC, NTSC, and QAM television
signals. It also processes the Photoviewer (JPEG) data of the SD and PC cards.
The composite, luminance and chrominance, or digital component signal of the DT
board are output to the DG board via the connector DT12/DG22. The composite video
of the analog TV reception as well as the luminance and chrominance output of the SD
or PC card input pass through the DG board without alteration and enter the H board via
the connector DG2/H2. IC2602 of the H board selects the desired video signals among
the many video inputs. The digital video of the digital TV reception enters the RGB
processor (GC4PRO).
