Tektronix’s Audio Test solutions can ensure audio loudness monitoring and compliance from Post Production, through to Broadcasters and Cable Operators. Our consistent Audio test and measurement approach makes Audio Loudness measurements the same way, regardless of signal or file format. This consistency enables traceability across the workflow and transmission chain.
Go beyond audio checks by automatically correcting audio loudness in the audio essence(s). Working with a variety of container types, audio level correction can be applied to the entire essence duration, and can be triggered by non-compliance to EBU R128 or ITU-1770-3 Audio Loudness Recommendations. Automated loudness correction works for Dolby Digital, Dolby Digital Plus, Dolby-E, PCM audio formats.
New changes to the ITU-R BS.1770-3 standard for measuring and controlling Audio Loudness now allow operators and engineers to easily monitor the audio loudness of their programs. Learn more about these important changes through this Tektronix webinar. Part 1 provides information on the basics of the standards.
Part 2 describes how to use a Tektronix Waveform Monitor or Rasterizer to measure and monitor audio loudness.
Cable operators have a tough job ahead: they must monitor the audio volume of commercials on many channels, not just one, and confirm that they have taken steps to control excessive loudness. This is a daunting task but help is on the way: the Sentry Video Content Monitor automates the process, 24/7, and keeps its own records. Download this Application Note to find out more.
|Cerify||Cerify is a content analysis system for quality control of file based video and audio, ingested from a variety of different file formats and wrappers. That performs full automated verification and checking of syntax, video and audio parameters.
|VQS1000||VQS1000 Video Quality Analysis Software is a reliable and sophisticated analysis algorithms applied to decoded MPEG-2 or H.264 video to identify stuck, black, macro-blocking, and compression artifacts. This enables operators to distinguish between impairments resulting from network distribution versus artifacts resulting from compression.
