Tektronix released an audio loudness measurement scheme, Beijing, China, April 8, 2010 -- Tektronix, a market leader in broadcast video testing, monitoring and analysis solutions, recently announced that it would add audio loudness measurement functions to its waveform monitor series products to further enhance the performance of its products. In order to meet the current needs of audio loudness measurement, according to the new ITU-R bs/According to the 1771 technical specification, tech has been able to provide customers with wfm6000/7000 or wvr6000/7000 series products with new firmware and software upgrade services with audio loudness measurement function. This upgrade includes increasing the audio loudness, setting the coefficient of the test, such as the time and speed start experiment table, the audio loudness session display, and the audio loudness monitoring of the industry-leading Dolby Digital plus. Tektronix's new audio loudness measurement function will be presented at the National Association of broadcasters (NAB) 2010 Annual Conference from April 12 to 15. The booth is n2522

with the conversion from analog TV to digital TV, the performance of audio and video will be further improved, enabling radio and television owners and program providers to provide their home customers with audio signals with a wider dynamic range than ever before. At present, some commercial programs make full use of the advantage of this wider audio dynamic range to attract the attention of the audience, but the audio loudness between the program and the inserted advertisements is significantly increased. This has greatly hindered the viewing experience of TV viewers, leading some governments around the world to consider formulating regulations or adopting laws to regulate this behavior

therefore, audio loudness has become a major issue faced by radio and television owners and program producers, and they are also working to solve this problem. In the United States, an ATSC industry expert group issued a recommended practice (ATSC a/85), which adopts ITU-R BS on how to measure audio loudness/1771 specification and take it as the basis of audio loudness measurement methods and guidelines. In Europe, EBU's p/loud group is also working on a new EBU proposal on audio loudness. The EBU practice guidelines are roughly the same as the ATSC a/85 recommended practice in some basic principles. Various test methods for audio loudness have been carried out in China and Japan to develop local audio loudness recommended practices. In accordance with the above specifications and guidelines, tech has developed a new tool for audio loudness measurement, which provides an audio loudness measurement method that is easy to be understood by program producers, radio and television owners and other operators

as the leader of video testing, we must always be at the forefront of advanced technology and devote ourselves to solving the challenges faced by our customers. The current discussion about audio loudness is also based on this goal. Ian Valentine, director of baseband video products of tech, said that by adding new audio loudness measurement functions to wfm/wvr 6000/7000 series products, we now provide customers with advanced and high-performance testing tools, so that they can work more effectively in accordance with the new specifications and new recommendations

audio loudness measurement is applicable to radio and television owners, network operators, content providers and IPTV service providers

system operators and engineering technicians engaged in radio and television and multi-channel video program distribution (MVPD) need to quickly and easily detect and troubleshoot those multi-channel audio faults that may cause punishment by the local government or reduce the number of users. Content providers need to effectively verify the multi-channel audio content, so as to reduce potential errors in the process of program or program format conversion, so as to reduce the probability of safety accidents. The audio content provided by them meets the requirements of radio and television owners for audio loudness and avoids costly rework. In order to solve these problems, Tektronix has added audio loudness meter and audio loudness session display (including audio loudness trend chart with adjustable display window), combined with the original audio level meter and audio status display, providing the most perfect audio monitoring tool for the market. Moreover, the new monitoring tool can also be used for Dolby Digital + audio decoding and monitoring (including audio loudness monitoring). Using the tag metadata display of tech can enable IPTV service providers to further improve the experience quality of viewers and provide home theater users with high-quality audio using Dolby Digital + technology
