RDP is a crazy complex protocol, and you have options for pretty much everything.
On the graphics side, you can send over draw commands "draw the letter A here using this font", or you can send opengl calls, or you can send dumb bitmap updates. You can get the other end of the connection to do compositing ("blur this buffer and overlay it over that buffer with 50% transparency").
You can also get the remote end of the connection to decode videos - so when you hit play on an MP4 video inside an RDP connection, the actual video decoding gets done on the client not the server.
