Recently we hear from Australia satellite user, how slow it is to upload to satellite when thousands or millions of packets are sent up. the computer on the satellite had to negotiate priority, length of message sent, and how many segments, and checksums. So, two way satellites may need to upgrade the transceiver and computer storage solutions.

GPS satellites and Galileo in Europe may have to redesign as we go into more users uploading and downloading back to earth. Cellphones are a lot more advanced with edge reduced bandwidth.

I spent two years on video compression, and we have not exhausted the reduced bandwidth by zooming software. Before you compressed to Mpeg2, you can still zoom to fewer pixels, then zoom to much larger number of pixels, after you decode Mpeg2? This has been demonstrated over the many years of digital camera development. Digital zoom is going to be beyond ratio of 24, but less than 50 times in general.

So, zoom is a video compression idea that will become more important as we look for data compression schemes.
