User Requirements for Video Monitors in Television Production;' Rec. ITU-R BT.500 '
Methodology for the Subjective Assessment of the Quality of Television Pictures;' Rec. ITU-R BT.710-4 '
Subjective Assessment Methods for Image Quality in High-Definition Television;' for some examples.
While imaging industry standards, engineering guidelines, and recommended practices are widely known, there are persistent lapses of understanding and disciplined implementation in program production communities. This can be due to many factors. Dominant ones are budgetary pressures and human frailties. THX, Ltd. offers services as a consultant and quality control supervisor for companies who lack their expertise internally. They are not perfect, nor are the companies who hire them. However, their involvement signifies a serious focus on standards and excellence. The ISF is a similar case.
My direct exposure to various levels of the digital motion graphics and electronic games community has revealed a more widespread failure to adhere to industry best practices in maintaining quality control and uniformity. These are newer entities compared to the television and film communities. Those older industries have a much better foundation in a standards based approach to quality control. Each generation of technicians must be educated to value image fidelity, program consistency, and artistic integrity. They also must be taught to value attention to detail, a passion for excellence, and disciplined adherence to industry standards and recommended practices. Failure in this process results in the kind of confusion and frustration expressed in this thread and throughout this forum.
