Conclusions

• There are strong needs and demands of High-Definition quality in telemedicine.

• Telepathology and surgery are good candidates and ready for trial. HD may also be expected to improve the quality of PC presentation.

• Multicast is strongly requested in telemedicine, which needs more bandwidth between KJ.
