Question

In a proposed telesurgery application the images will be transmitted at 2 x 10 8m/s over a round-trip distance of 900 km. The compression and decompression processes for the images will take a total of 22 ms for the round trip, and other sources of delay amount to 9 ms for the round trip. What is the total round- trip delay

Answer 1

why would you transmit pictures in both directions for telesurgery?
we could cobble together various scenarios but they are meaningless unless we understand why the doctor would want to see himself and why it might be viewed at the other end as well.

I would better characterize this as images captured at the remote are compressed, sent, decompressed then viewed by the doctor.

going in the other direction would be commands from the surgeons joysticks to the apparatus at the remote site -scalpels, probes, etc.

Answer 2

4.5 ms for transmission
22 ms for compression/decomp
9 ms misc.
------
35.5 ms total
