Garry < Not quite right. The encoding on the images by applying mathematic formulas to describe the image is done entirely to reduce the amount of data to transfer per one frame of video. Video codec were made to specifically reduce the video data size, otherwise there would be no reason for them.GarryB wrote:You are quite right that video is probably the most demanding of bandwidth but this is made worse with encryption as this often adds to the volume of data that needs to be transmitted.
Regarding the tapping of communications. Modern datalink systems use a method called frequency hopping. This method makes it significantly more difficult to tap the communications, however it does not render it completelly impossible. Today digital signal processor chips are quite powerful and not very energy demanding so it is possible to setup a system of chips listening on all the major UHF,VHF channels to intercept the data link as it shifts from one frequency to another. And then rapid audio/video processing capabilities of modern CPUs make it possible to have nearly real-time video/audio streams of enemy communication. Im not taking into account the encryption as even the military grade encryption can be brute-forced 0 but it needs some time to do it. So no matter the netcentrc warfare hardware - it will never be completely safe.
