Mitsubishi Electronics WS-48613, WS-65513, WS-48513, WS-55513 manual PCB-SIGNAL Video Path

The Sub picture signals from IC2B00 are directed to IC2G00, the Sub Decoder. Switch circuitry in IC2G00 selects Sub picture signals from IC2B00 or the AV- SW(2), IC2K00.

As in previous chassis, the main and sub selected YPbPr signal are direct to the PCB-SIGNAL.

PCB-SIGNAL Video Path

Figure 5-2shows the PCB-SIGNALVideo Signal Path. Sub picture signals from PCB-TERMINAL are routed directly to the Sub YPbPr inputs of PCB-DOUBLER.

The main picture signals from PCB-TERMINAL are routed to COMP SW-3, IC2H01. IC2H01 selects the main signal from the PCB-TERMINAL main outputs,

or the MLINK signal from the MLINK Decoder, or the RGB signal from the DM Module. The output of IC2H01 is applied to the Main Picture inputs to the Doubler circuit.

Note that the OSD RGB signals from the DM Module are also directed the VCJ, IC2V01.

On-Screen Display (OSD) signals are generated in the DM Module, and when the signal source is not the DM, OSD is inserted in the main picture in the VCJ. If the source is from the DM, the DTV Tuner or 1394 inputs, OSD insertion occurs in the DM module.

The diagram also shows that Convergence OSD sig- nals are applied to the VCJ and inserted in the VCJ.
