Microsoft Engineer about PS3 Horizontal Scaling in SDK
Tuesday
From Bruce Dawson (Microsoft senior software design engineer) on Andre Vrignaud's Blog:"I see no sign that the PS3 contains a chip that can do vertical scaling, and this new feature (horizontal scaling) is a poor substitute for a true hardware scaler. It is a step forward for owners of 1080i only HDTVs, once PS3 games support it, but it is nowhere near as good as the Xbox 360's scaler."
This recent announcement is just for horizontal scaling, and horizontal scaling is easy. To do high quality horizontal scaling you just need to buffer up a few pixels and intelligently average between them.
Cheap horizontal scaling is even easier: you just send pixels to the video output a bit slower (or send pixels at the same rate, but read them from memory slower). It's the sort of thing that consoles have always been able to do. This new horizontal scaling feature just sounds like they are adjusting the video output rate.
