We propose a new evaluation method for video of tele-neurosurgery under microscopic view. We conducted a subjective evaluation of video by 16 evaluators to determine the minimum video bit-rate required to make decisions in tele-neurosurgery under microscopic view. In this evaluation, we developed a new evaluation method that is unaffected by learning from evaluating the same videos more than one. Our results showed that a video bit-rate of at least 384 kbps was necessary in order to make decisions in tele-neurosurgery. Also, contrary to general expectation, the expert subjects scored the low quality bit-rate videos higher than the residents subjects did. Moreover, if the quality of the original picture was poor, the evaluation result was not related to the compression ratio. These finding should be took into account in future evaluation of tele-surgery systems.
