摘要

Great consumer experiences are created by a convergence of sight, sound, and story. This paper presents an in-depth quantitative analysis of the neurobiology and optics of sight. More specifically, it examines how principles of vision science can be used to predict the bit rates and video quality needed to make video on devices ranging from smartphones to ultrahigh-definition televisions (UHDTVs) a success. It presents the psychophysical concepts of simple acuity, hyperacuity, and Snellen acuity to examine the visibility of compression artifacts for the MPEG-4/H.264 video compression standard. It looks at the newest emerging international compression standard for High-Efficiency Video Coding (HEVC). It will investigate how the various sizes of the new coding units in HEVC would be imaged on the retina and what that could mean in terms of the HEVC video quality and bit rates that would likely be needed to deliver entertainment-quality content to smartphones, tablets, high-definition televisions, 4K TVs, and UHDTVs.
