Texture compression is an important tool in real time texture mapping on several levels. Besides from increasing sampling performance due to cache efficiency and lower memory requirements, it can significantly decrease texture loading times. In bandwidth constrained situations, a texture streaming system is not always able to load the required texture data in time, either stalling the visualization...
A prototype UHDTV video coding system with spatio-temporal down-/up-sampling is proposed. The system prereduces the spatial resolutions and/or frame rates of source UHDTV videos to 2K 60P before being encoded by a standardized codec such as HEVC/H.265. On the reception side, the decoded video is up-sampled to 4K 120P, 4K 60P, or 2K 120P resolutions depending on the specifications of the displays....
