AG 5 supports the work of the MPEG working groups by visual quality testing. A key responsibility is to evaluate the visual quality of emerging technologies, assessing whether they meet the necessary
criteria to begin a new standardization project. Such investigations typically include a Call for Evidence (CfE) in which candidate technology is assessed. By this, its contribution is fundamental to shaping the direction of future standards and technologies.
We are envolved in the definition of Calls for Proposals (CfPs) for new standardization work items for coding of visual media, investigating and recommending both subjective and objective quality evaluation methodologies. In this context, we actively participate in the selection of test material and coding conditions for CfPs, ensuring that appropriate relevant content is used for the evaluation. The same applies to Calls for Evidence (CfEs).
We support the working groups during the standardization process by designing and conducting visual quality tests, processing the resulting raw data, and producing reports on the evaluation results as needed. When a standardiztation project is completed, we are closely involved in the design and the conduction of verification tests, verifying its performance compared to existing standards to ensure that it offers improvements and meets the required benchmarks.
We liaise with ITU and other relevant organizations to develop new quality assessment standards or improve existing ones, ensuring continuous enhancement and alignment with international best practices.
