It depends alot on what your set top box needs to do, but linux is very good. Standard linux would probably be alright (instead of RT-Linux) but that would depend what you need to do. eCos, pSOS and ThreadX are probably too "small". I have heard QNX is also very good. Stay away from WinCE its shit!

There are 3 level of application for set top box, base application, enhanced application, and totally interactive application.
Why eCos, pSOS and ThreadX are probably too "small"?
Isn't pSOS as good as, or say as "big" as VxWorks?
What about VxWorks vs QNX Neutrino vs every kind of linux(no matter realtime or not)?
And any comment on Nucleus?

may be that VxWorks is completed and more simple to develope, but is not free.

Standard linux should do a nice job for multimedia type of real time... But, try your best to get a 2.6 kernel going with your set top. The latency improves quite a lot.... Many distro targeting "small" device are based on earlier kernel (2.0, 2.2)...

Maybe rt-Linux is better.

VxWorks is not a good choice for applications such as STB.

Because STB doesn't need a GUI, so linux will be the best choice. It depends if your CPU has a MMU. If no, you can choose uclinux, quite easy to port. Otherwise, you have to use QNX or other RT linux supporting MMU.
