The television would request a 16:9 fragment of the video (or version of 
the video, depending on the outcome of ? vs #) to avoid doing the cropping 
If the video is in 16:9 the server will do nothing, if in 3:2, the server 
will crop according to what is the best algorithm for that file (ie: there 
may be extra knowledge server-side to figure out how to crop in a nice way 
the video).
