Final year project

Hi everyone,
I am looking for a project for my "Video systems" class. Here is a list of things I might do. I want it to be somewhat easy to find components and to develop. If there are any ideas or any sites from where I can get a theme to work on it will be really appreciated.
Thanks

"Video" system based on osciloscope in XYZ mode with microcontroller
"Selenq" system digital or analog
RF Video Transmitter (if it really works)
Video decoders
Characters generators
Video generators based on microcontrollers, FPGA, etc.
Color mixers
Any other related to TV/Video systems
