7/31/2003 - Tektronix Inc. (NYSE:TEK), the market leader in picture quality analysis, announced that China's Academy of Broadcast Science (ABS) under the State Administration of Radio, Film, and Television (SARFT) has recommended Tektronix analysis tools to determine video picture quality at its National Center of Test and Metrology for Radio and Television.
ABS/SARFT evaluated the Tektronix PQA200's performance by comparing the equipment against subjective methods of testing quality. In subjective tests, viewers physically watch video monitors and sound alarms when they perceive degradation in the picture quality. However, subjective measurement is time intensive and thus impractical, especially for manufacturing operations. SARFT's tests proved that objective analysis provides the fast, accurate, and repeatable picture quality measurements necessary in the development of video equipment, such as set-top boxes, MPEG codecs, and video servers. In the test, a high correlation coefficient of 0.94 was obtained from the comparison result of subjective and objective quality ratings. The measurement is based on Emmy-award-winning technology in Tektronix' PQA200 Picture Quality Analysis System.
"Assessing the impact of compression on the output quality of video systems can be achieved through a combination of traditional signal level measurements and subjective testing. However, subjective measurements are very time consuming and place a high demand on employee resources. The objective of our work is to find the most effective measurement technique for picture quality measurement," said Ms. Zhang Hong, Director of the SARFT/ABS National Center of Testing and Metrology for Radio and Television.
"Tektronix is proud to further its alliance with SARFT/ABS as the organization continues to develop its country's next-generation digital video technology," said Todd Biddle, General Manager, Video Product Line, Tektronix. "The Tektronix PQA200, and the newer PQA300, offers a unique analysis system for manufacturers who need the confidence and accuracy of subjective measurements yet must meet market demands for delivering high-quality, video-specific devices quickly."
About the Product
The PQA200, and its replacement, the PQA300, are single channel analysis systems that provides complete, in-depth and objective picture quality analysis. The PQA is both a generator and analyzer of reference test material for testing compressed video systems. Standard inputs and outputs are 270 Mb/s serial component, with options for analog composite interfaces. The PQA can be used for algorithm tuning of video compression products and quality verification of video equipment, systems or networks.
About the ABS and SARFT
ABS is an academy led directly by SARFT. ABS's origin is the Institute of Broadcasting Science of the former Ministry of Radio, Film & Television (MRFT). Established in 1958, the institute accomplished many great projects, such as the system decision and the initial system establishment for national mono-TV, color-TV and FM radio. Now ABS is taking ten national research projects such as: HDTV, DAB, broadband cable integrated information service network, DVB conditional receiving system, as well as 43 ministerial research projects. For 42 years, ABS has always been advanced in the broadcasting S&T field in China and stood at the leading edge of international broadcast S&T.
