I just attended a brilliant IEEE presentation in Austin by a man who is trying to supplant MPEG. His algorithm, called ZPEG, can supposedly deliver visually perfect (not lossless, but difference less than quantization error, making it invisible) video at 1Mb/s, and lossless compression at a 10:1 compression ratio. Since the algorithm is symmetric, any device that can decode a given ZPEG video in realtime (which would includine things like cellphones) can also encode it in realtime, and it takes only a fraction of the computation required by MPEG. Website's at zpeg.com. They have a downloadable demo that you can mess with to make your own videos and see the video quality and the bitrate of the codec for yourself. He mentioned he was having trouble getting support in the industry so I thought I might raise some interest among multimedia enthusiasts.
JPEG and MPEG both perform 2-dimensional transforms. ZPEG works by performing a 3-dimensional (width, height, and time) Fourier transform, which is a lot more efficient because an entire extra dimension is being compressed. So instead of each frame containing its own grid of macroblocks, each macroblock spans several frames. Also does away with MPEG macroblock search algorithm, resulting in a massive speedup.
What do you guys think? Are you interested? Subjectively perfect video at 1Mb/s that you can encode in at least realtime on your iPhone? I'm very excited.
This is totally legit, by the way. The guy who gave the presentation, Raymond Westwater, is a PhD and the company that owns ZPEG, Futureware, is the same one that made the AVI specification.
[Tell me if this isn't the right forum to talk about this.]
