Abstract: Stereoscopic video transmission in telemedicine application requires the data to be transferred with a minimal jitter. It is not possible to send stereoscopic video at full HD rate on single internet service providers (ISPs) as the bandwidth becomes a bottle-neck and congestion can lead to packet drops, eventually leading to jitter in a video. This could be a circumvented by employing multiple ISPs to stream stereoscopic video utilising multiple real-time packets (RTPs) sessions. Usage of multiple ISPs results in multiple network paths between the video streaming device and video consumers. This concept effectively involves aggregation of bandwidth, delay, jitter, packet loss, and other qualitative network attributes with respect to every ISP participating in the video transmission process. This article analyses through simulation collective delay and jitter which affects the video reconstruction process and concludes with the estimation of minimum qualitative network parameters required.
