The China Academy of Broadcasting Science (ABS) chose new Tektronix Inc. instruments for its digital television (DTV) and high-definition TV (HDTV) standards development, compliance testing and certification.
The new Tektronix PQA500 Picture Quality Analyzer, WFM7100 Waveform Monitors and MTS430 Moving Picture Experts Group (MPEG) Analyzers are designed to augment existing Tektronix video equipment to provide ABS with an efficient and comprehensive video diagnostic and test lab, said Tektronix.
ABS is the broadcasting R&D institution of the Chinese government that defines and develops the nation's technical standards for FM radio, digital audio broadcasting (DAB), satellite broadcasting, cable TV and HDTV.
With the proliferation of digital TV throughout China, the ABS lab is the DTV and HDTV standards gatekeeper for the broadcasting industry in China.
The lab offers standards compliance and acceptance test services for broadcasting equipment and systems to be applied by local broadcasters, cable TV network operators and satellite TV operators.
Tektronix provided assistance to ABS to increase the technical strength in China for next generation digital TV.
Incorporating eight new Tektronix patents and embodying the most comprehensive human vision model, the PQA500 is designed to provide the most complete suite of measurement and diagnostic tools for picture quality analysis including full support of high definition (HD) formats, said Tektronix.
Video developers and broadcasters can quantify subjective video responses with the PQA500 enabling them to tune their video offerings for differences in format and delivery mechanisms. This enables them to consistently produce an optimal customer viewing experience by ensuring the highest quality levels are achieved at all points along the video path, the company claims.
The instrument enables codec developers and broadcasters to optimize resources while also meeting customer expectations for consistent picture quality regardless of the viewing medium.
The PQA500 Picture Quality Analyzer enables engineers at ABS to use quantitative techniques to predict subjective video quality ratings, not only between video of the same video standard, but also between 1080i and 720p HD, HD and SD, 525 line and 625 line SD, 30 frames per second and 25 frames per second, SD and common intermediate format (CIF), HD and CIF.

This capability is a first for the industry, enabling direct support of video repurposing involving conversion from one video standard to another, according to Tektronix.
