Google TV versus Chromecast

How Google TV Differs from Chromecast

I guess Chromecast lets you send video content from your PC to your TV.  But Google TV is like Apple TV, it eliminates the need for a PC, but pulls content from your Internet connection and then delivers it into one of your existing unused inputs.  My guess is that it would be a good idea to have an HDTV so the content will look decent.
