Demonstration Setup, File Locations, and Instructions

•Project directory: DE2_70_TV

•Bit stream used: DE2_70_TV.sof or DE2_70_TV.pof

•Connect a DVD player’s composite video output (yellow plug) to the Video-IN 1 RCA jack (J8) of the DE2-70 board. The DVD player has to be configured to provide

o NTSC output

o 60 Hz refresh rate o 4:3 aspect ratio

o Non-progressive video

•Connect the VGA output of the DE2-70 board to a VGA monitor (both LCD and CRT type of monitors should work)

•Connect the audio output of the DVD player to the line-in port of the DE2-70 board and connect a speaker to the line-out port. If the audio output jacks from the DVD player are of RCA type, then an adaptor will be needed to convert to the mini-stereo plug supported on the DE2-70 board; this is the same type of plug supported on most computers

•Load the bit stream into FPGA. Press KEY0 on the DE2-70 board to reset the circuit

Figure 6.2 illustrates the setup for this demonstration.
