Project #106: Low Latency, High Bandwidth Video Transmission for VR Systems

Back

Description:

With the increasing popularity of virtual reality (VR) headsets, the restrictions of a wired connection decrease immersion and limit the freedom of movement of users. Wireless video streaming allows the mobility from an all in one virtual headset while utilising the power of a personal computer to maintain frame rates required for virtual reality.

Current wireless streaming technology is not suitable for VR systems due to their high fidelity streaming requirements. Transmission to the VR system would require very wide bandwidth as current VR headsets call for a minimum a 90hz refresh rate with extremely dense resolutions. Having low latency is also vital as delays and stuttering in the video stream can cause motion sickness for the user.

This project aims to research low latency, high bandwidth wireless video transmission that would improve the user experience for virtual reality systems. As there would be a clear line of sight between the computer and headset, we propose that an effective solution can be designed where the headset is powered via battery and video is broadcast wirelessly from the computer.

Outcome:

●      Literature review looking at existing solutions and technologies

●      Investigation into radio transmission and signal processing

●      Investigation into requirements and limitations of implementation

●      Design and evaluation of possible solutions

●      Production of a functional prototype

●      Validation of prototype through user feedback and framerate analysis
