But surely nothing has really changed over the last 15 years. Processing power, storage, and bandwidth all get larger, but so do the images. Wavelets must be a great technology if you want to fit a HD video on a CD and play it with an expensive machine. I am not arguing against compression. But you have to admit that Jpeg2000 has been the next big thing for a long time. Surely it is cheaper to just use h264 and have more storage?
- KaiserPro 14y agoDepends on the application, In broadcasting for example bandwidth is painfully expensive, hence the shift from MPEG2 to h.264 for consumers (although in the US its much more complicated as everyone seems to recompress everything badly on TV. Its like watch a pirated copy.) It just takes a long time to get from approval to acceptance. The other problem with JPEG2000 is that its not really a motion codec, so it doesn't degrade well over lossy links without special sauce. All of which is non standard.
