Is there anymore a peripheral chip that would allow me to use an old tv as a display for Arduino Uno ?
A chip that would contain the memory for graphics and would take care of all the timing for creating a composite video or RGB signal. I would prefer graphical over alphanumerical and color (8 is enough) over monochrome, but at this point anything is ok.
Not exactly sure what you are wanting but you can drive a monitor from an AVR.
You can find more information by googling.
Here are a few links:

Thank you for your reply bperrybap but all the links you provided seem to be about using the Arduino itself to generate the timing for the video signal, wich is not what I m looking for. I need the Arduino to be free to do whatever number crunching needs to be done.
I tried to Google for something suitable prior to creating this thread, this is what I found:
TellyMate Batsocks - TellyMate
Doesnt seem to support user defineable graphics and seems to be discontinued.
Gameduino http://excamera.com/sphinx/gameduino/index.html
Seems to be discontinued.
MAX7456 osd ic by Maxim Integrated
Doesnt seem to support user defineable graphics and all the component suppliers that I usually use says: "Obsolete, no longer available".
Hopefully that gives some idea what I m looking for
Still no clue what you are looking for.
TellyMate is doing the same as what the links I provided.
It does provide a foreground task of reading a serial port to update the display output.
Perhaps if you fully described what are you wanting to do people could offer some suggestions.
If you are looking for an environment that can do lots of tasks and display graphics on a display, I think something like Raspberry PI is much more suitable. On the PI you have full development tools using a real OS with all kinds of languages including full source level debuggers.
