A Short History of Television Recording

A Retina-Based Perceptually Lossless Limit and a Gaussian Foveation Scheme With Loss Control

“…9 shows compression results for a frame of the 720p sequence parkrun. Again, All compressed frames were all encoded using the H.264/AVC reference software JM version 18.5, and, except for the quantization pass , they were encoded using the same configuration 9 . Once again, we wanted to verify how much foveation filtering could possibly improve the perceptual quality of an uncompressed frame.…”

“…8, we also displayed magnified macular images of such frames in order to facilitate the visualization of the results. The point for the 10th frame is located at the center of its macular image 10 . For convenience, we now made PPI so that in becomes the actual viewing 9 The only differences between this configuration and the previous one are the following:…”

“…With that in mind, we modify a few entities presented so far in order to allow visual perceptual loss. We start by the -modified number of cones per pixel of a pixel centered at that can be defined as: (9) where is given by (4) and is given by (8). This modified version of the number of cones per pixel just reduces its value pointwisely according to the information reduction factor .…”

“…Some notorious examples of such point of view are: the eyeglasses [5], [6] (which exploits a good understanding and modeling of the eye optics); the halftone printing [7], [8] (which exploits a good understanding and modeling of the eye resolution); and the television [9], [10] (which also exploits a good understanding and modeling of the eye resolution in addition to a good understanding of the trichromatic theory). The usefulness of those inventions reveals the relevance of our research.…”

Design of a tool for the visualization of historical data

“…The list is as comprehensible as possible. The bulk of the data comes from previous media historical and media archaeological accounts such as (Abramson & Sterling, 2003;Kattelle, 2000;Watkinson, 1994;Zielinski, 2010) and the technical details about particular formats comes primarily from the standard reports of organizations such as SMPTE, ISO, and ITU. The specific information of each format was recorded in a structured data file and a custom made program processed the data and produced each chronology.…”
