In his doctoral dissertation, Alireza Zare investigated how high-quality 360° video content can be delivered more efficiently for immersive virtual reality (VR). He developed new video compression and streaming methods that prioritize the part of the video a user is currently looking at, enabling significant reductions in bandwidth use while maintaining visual quality and compatibility with existing consumer devices. The research demonstrates that these techniques can reduce streaming bitrate by tens of percent and enable high-resolution VR video even on devices with limited decoding capability. These advances can make immersive VR experiences more accessible and scalable for industries such as entertainment, education, and remote collaboration, benefiting both content providers and end users.
