These guys describe their product as Virtual Broadband, implying that it speeds up your dialup connection to the point that you can’t believe it’s not broadband! It appears that the product routes requests for web pages through their network, sending you to pages that have been compressed using their proprietary techniques.

User Paul was quite pleased with the service, saying All in all I was suitably impressd especially when I tried in on my lap top with my GSM connection. Cute to see everything speed up the way it did.

This appears to be the Data Compression Blue Book published by the Consultative Committee for Space Data Systems. It’s a nice document, but I’m not sure if the standard described here is actually in use. As is so often the case with standards documents, I find myself yearning for some accompanying reference code. Alas, there is none that I know of.

Note: a related document discussing performance characteristics of the recommendate can be found

MotionWavelets is a software video codec that delivers real-time, high-quality video compression to the PC-based digital video user. Powered by a wavelet-based compression engine optimized for MMX processors, MotionWavelets compresses 640×480, 30 frames per second video with VHS quality, in real time on a PII/450MHz PC. MotionWavelets will compress greater than 60 fps 320×240 on any P/MMX 200MHz PC or above. MotionWavelets is available as a Video for Windows (VfW) installable codec and a Software Development Kit (SDK).
