However, support for high • Support for multiplexed rendered light field images resolution, low latency in-home streaming at high image quality is • Higher image quality through ETC2 support still a challenging problem. To enable this, we enhance an existing • Optimizations for ETC1, ETC2 and DXT1 encoding open source framework for in-home streaming. We add highly • Streaming up to 5K resolution using 10 GbE optimized DXT1 (DirectX Texture Compression) support for thin desktop and notebook clients. For rendered light fields, we • Foveated compression through real-time eye tracking improve the encoding algorithms for higher image quality.
