Below we show how by using signal processing techniques such as multiresolution representation and scalable coding for all the components of a 3D graphics object geometry texture and animation we enable online dynamic content adaptation and thus delivery of the same content over heterogeneous networks to terminals with very different profiles and its rendering on them. We present quantitative results demonstrating how the best displayed quality versus computational complexity versus bandwidth tradeoffs have been achieved given the distributed resources available over the end-to-end content delivery chain. Additionally we use state-of-the-art standardised content representation and compression formats MPEG-4 AFX JPEG 2000 XML enabling deployment over existing infrastructure while keeping hooks to well-established practices in the game industry.
