I am doing a auto-driving project with a turtlebot. We are sending the camera's videos to the remote pc, and calculate the velocity in the remote pc, and send it back to the turtlebot. The problem is, the video arrives to the pc with a few seconds delay. Can I reduce the delay, or should I just put the calculating code to the turtlebot?

Quick suggestion: see whether using compression helps. image_transport can help with that (theora fi). But do make sure the image stream isn't already compressed.
