There's splashtop 2 , which lets you remote desktop your pc to an android tablet , and will work for games if your pc is strong enough. As far as i can tell(from some google research) it's the best one for games in the market. If your TV can run android apps, you might be set. If not, there are plenty of set top boxes or hdmi plugs that run android. But choose one that would be fast enough. Regarding doing it alone: as far as i can tell, efficenly compressing the video on a pc with low latency and decoding it on the other side is a hard problem, not a side project. And if you try,i think it would be wise to use something stronger than raspberry pi ,as least for starters.
