Abstract

Real-time data transmission through telepresence surgery consideration as an important issue due to using low video quality transmission techniques for transferring video data. Many types of research have been conducted on real-time video transmission but very few have been focused on surgical telepresence and improving video quality during the surgery. The main aim of this research is used to improve the video quality by improving the path quality which the video data is transferred. The proposed system consists of a Transmission Control Protocol (TCP) Friendly for controlling congestion while selecting the best quality of path for transmitting the video data. It selects the best quality of path that is less likely to be affected by network impairments and provides a higher priority to the TCP friendly packets than the non-TCP friendly packets. Results for the end video quality has been improved by 4.2 dB compared to the state of art based on path quality, PSNR and Packet Traffic are based on congestion and also the processing time has been improved by 9 ~ 13 Frames per Second on average against 5 ~ 9 Frames per Second of the state of art. The proposed system makes sure that the packets are sent through the best path and that is done by giving the TCP friendly packets higher priority than non-TCP friendly packets, also considers the available bandwidth, loss rates and other parameters that are utilized in other systems. In addition to the state of art, it adds congestion factor and makes sure that only the path with minimum distortion was used to send maximum data so that the receiver site can handle the transmitted data.
