Data Transfer process #16

Closed 10penab closed 10 years ago

To send the data, we can't use a RockBLOCK iridium sateline, this is because it's too slow to keep up with the increase in data. If Rsync is used we need to find a way to compress the files down, a lot, as well as being able to compress the files when it reaches a specific amount of files, to be able to transmit it.

Method of compression using Tar, using either gz or bz2. http://www.tecmint.com/18-tar-command-examples-in-linux/

Different ways of live streaming from the pi camera, straight to a website. http://techzany.com/2013/09/live-streaming-video-using-avconv-and-a-raspberry-pi/ http://www.raspberrypi.org/archives/3890 http://www.raspberrypi.org/phpBB3/viewtopic.php?f=43&t=43969 http://www.raspberrypi.org/camera Not sure which one is better.

We will use rsync, we may compress the images first but probably unnecessary.
