Abstract
Methods, systems, and techniques for projecting streamed video are provided. Example Enhanced Video Systems provide support for streaming high resolution video in limited bandwidth hardware environments. In one example, an Enhanced Video System comprises a real time, interactive rendering system, a display system, and one or more display units. The rendering system comprises a high resolution graphics engine (e.g., a VR/AR gaming engine) capable of generating high resolution video and two graphics computation units. The projection system comprises two video capture cards to capture the generated video stream and forward the captured video stream to a projection mapping engine. Projection mapping engine consolidates and stitches together the received video stream as appropriate to render the video stream over display units to the target viewing environment such as a dome/sphere. In the example described, an 8K resolution video is streamed and projected despite bandwidth limitations of current video capture card technology.
