Abstract
An immersive video display system is configured to display an immersive video formed by a plurality of compressed environment maps. The immersive video display system includes a decompression unit to partially decompress each compressed environment map to create a partially decompressed environment map. A texture rendering unit creates an image for a view window for each of the compressed environment maps by texture mapping the visible portion of a texture projection using the partially decompressed environment map. By decompressing only a portion of the compressed environment map, the immersive video display system requires less processing time to generate the contents of the view window.
