There are some suspicious statements in that article. That was one of them. VHS quality at 300 kbps? DVD quality at 700 kbps? Then in the next paragraph they say DVD at
700 Mbps?

And I do not see the claimed reduction in network congestion if they are unicasting these streams (but they also say the server sits at the service provider, rather than the source of the content. This is too vague to understand what assumptions they are making about content distribution).

Unless they have changed something from when I first looked at their claims (2 years ago?) it is not a compression algorithm. It is an error-resilient way to transport some native data (which may itself be compressed), and is at least 5% larger than the original data block. But, regardless of how they are packaging the data, the cable network still applies its own forward error correction on top of this. SO, I do not see how this does any VoD-enabling magic.

It seems to me that for their method to work for VoD the local system needs to reconstruct the whole original file, then run this in a loop to playback starting from any point and jumping to any point. Seems no different from downloading the whole file to your local system the regular way, which also reduces the requirements back at the server. In other words all the churning would be done locally when you fast forward, rewind, etc.
