Bill Reckwerdt - ArticlesHow to Do Objective Video TestingTo make optimal choices, it is necessary to have knowledge about how particular choices affect the impression of the viewer. This is the central question of all video quality research. Video Testing for STB ManufacturersSet-top box (STB) functions are continually advancing, but the customers' reactions are usually centered on the quality of the picture. So testing is increasing important. Video Testing for BroadcastersEach broadcaster - traditional or web caster - must deal with rapidly changing varieties of programming, new video processing algorithms, and new compression algorithms. How can broadcasters know if a new algorithm is better than their current choice? Video Testing for Encoder ManufacturersFor visual and audio data, some loss of quality can be tolerated without losing the essential nature of the data. By taking advantage of the limitations of the human sensory system, a great deal of space can be saved while producing an output which is nearly indistinguishable from the original.The question must be asked. How much data can be removed before the customer has a violent reaction. Who Are You Going to Believe, Me or Your Own Eyes?Over recent years, advances underlying the capture, transfer, storage, and display of images have created situations where video communication has become economically feasible. This paper creates a framework for optimal compression/ CODEC trade-off choices. Video Testing made Easy for BroadcastersThis paper explores the challenges Broadcasters face when assessing video quality. Many factors affect the video before it gets to the TV: compression, image processing, scaling, decoding, transmission, etc. Repeatable Video Testing Tools for Equipment ManufacturersThis paper explores the challenges Video Equipment Manufacturers face when assessing video quality. Assessing video quality ultimately depends on the customer's reaction on their new display (PC, POD, TV, etc.). Current Status of Video Objective MeasurementsThis paper explores the challenges associated with assessing video quality. When dealing with equipment to process TV & video transmissions, every design depends on accurate, repeatable measurements. A complex relationship between objective parameter measurements and subjective video quality exists. The goal is to achieve an objective metric; that is an automated measurement. Measuring to Find the Best Video Processing and Compression AlgorithmsEach broadcaster - traditional or web caster - must deal with rapidly changing varieties of programming, new video processing algorithms, and new compression algorithms. This whitepaper discusses how to choose the best algorithm.
