Demo
This is the link to the youtube video of my demo: https://www.youtube.com/watch?v=GpSiaoRfdh8&feature=youtu.be
The picture above shows a clear view of the black vertical lines present on the screen. These lines exist because of a timing issue that stems from the downsampling of the input video. The dval signal which indicates that there is valid data on the 16bit output bus from Altera's demo files seems to be high when the data is not actually valid yet. This timing issue is difficult to fix due to the complex nature of the video input decoding system. Beyond these vertical lines, the frame buffer performed as expected. The video is supposed to be in grayscale and the gray box was expected to move a lot with each button press.
