data format.

Finally, the YcrCb_to_RGB block converts the YcrCb data into RGB data output. The VGA

Controller block generates standard VGA synchronous signals VGA_HS and VGA_VS to enable

the display on a VGA monitor.

 Demonstration Setup, File Locations, and Instructions

• Project directory: DE2_115_TV

• Bit stream used: DE2_115_TV.sof or DE2_115_TV.pof

• Connect a DVD player’s composite video output (yellow plug) to the Video-In RCA jack (J12)

of the DE2-115 board. The DVD player has to be configured to provide:

o NTSC output

o 60Hz refresh rate

o 4:3 aspect ratio

o Non-progressive video

• Connect the VGA output of the DE2-115 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 DE2-115 board and

connect a speaker to the line-out port. If the audio output jacks from the DVD player are RCA

type, then an adaptor will be needed to convert to the mini-stereo plug supported on the

DE2-115 board; this is the same type of plug supported on most computers

• Load the bit stream into FPGA by execute the batch file ‘de2_115_tv.bat’ under

DE2_115_TV\demo_batch\ folder
