I would actually turn the use case the other way around: [[ Silvia owns a old television that can only display the 4:3 ratio and not the modern widescreen aspect ratios. To avoid paying a premium in network fees, she would like the television to request only what can be displayed to avoid wasting bandwidth. ]] So: http://www.greatmovies.com/StarWars.mp4#aspect=4:3 will request the 4:3 fragment of this movie while http://www.greatmovies.com/StarWars.mp4#aspect=16:9 will request the 16:9 fragment of it I found http://en.wikipedia.org/wiki/Aspect_ratio_%28image%29 a useful documentation.
