What solutions are available for generating video signal

integrated-circuitvideo

I'm looking for a video chip that could handle VGA resolution.
It should be able to provide VGA, HDMI and Composite video out.
It needs to have some basic hardware acceleration eg. built in support for 80×25 text rendering, sprites.

What I have found:
Bitbang microcontroller libraries – either they don't provide HDMI or they requrire expensive microcontrollers.
MOS 8568 – the thing I'm looking for, but is no longer produced and has no HDMI.

I have looked at similar questions on stackexchange,but their about monochrome composite, which can be done with Arduino TVOut, or their about HD quality video.

HDMI is kind of inaccessible to hobbyists; the signal requirements are quite tough. If your driving chip has a USB interface you could try http://www.mouser.com/catalog/specsheets/UFX6000-VE.pdf . Given the high data rate of HDMI, I don't think you're going to find a cheap solution. Built-in HDMI support on SoC is probably cheapest in terms of parts count.
