In the continual evolution of its RTM product family, Video Clarity Inc. announced two new additions to its RTM line of real-time audio and video monitoring solutions.
RTM IP is a new model that enables perceptual testing in the ST 2110 IP domain, while the company’s RTM Manager control interface now includes automated file QoE for automated quality testing.
“Our major goals this year were not only to apply new features that current users have asked for, but to create more automated tools and broaden the applicability of our products for new users. With these new RTM products, we’ve done both,” said Blake Homan, president and founder of Video Clarity. “Through RTM IP, service providers who continually test for video and audio quality to understand the home viewer’s quality of experience can for the first time do so with perceptual testing in real time in the IP domain. Additionally, manufacturers can now apply picture and audio quality testing functions in long form to developing products in R&D and QA applications.”
Through Gigabit Ethernet and 10 Gigabit Ethernet IP interfaces, RTM IP can run automatic, full reference, real-time quality testing in the IP domain for uncompressed and compressed video quality streams. It works by playing a test reference source into the network while performing a comparison of that source to downstream processed video and audio. The system enables program originators, service providers, and manufacturers’ test labs to apply RTM testing to IP networks, and importantly, to do it using the new SMPTE ST 2110 media flow technology.
Users can apply perceptual video quality tests to encode processing in an ST 2110 network environment simultaneously with audio quality, lip sync, and full program loudness up to 16 channels. Whether they need to measure the quality of output delivered to a downstream channel or a home viewer, or they’re taking measurements during R&D and product development, users can test the performance of their network video-processing functions automatically and in real time without setting up recordings. This time-saving feature lets users focus on other work while the quality-monitoring and logging test is underway. RTM IP is available as new model RTM-S2043-IP and as a software option for ClearView IP systems that have 10G IP interfaces.
Meanwhile, the other addition to the RTM family — RTM Manager with file QoE — applies an easy-to-use, automated file-testing routine for VOD or OTT file-encoding workflows for users that need an added layer of video and audio quality measurement, with a threshold for recording low-quality events in the baseband domain.
“Many files get passed into distribution that either cause a loss of video quality or have audio problems that file-checking routines are sometimes not equipped to catch,” Homan continued. “The new file QoE function in RTM Manager gives file-preparation centers a time-saving, automated way to test distributed content.”
Built for postproduction and file-delivery centers that handle all kinds of content — such as for broadcast, cable, IPTV, and OTT program delivery — this new RTM automated measurement process tests HD and SD video faster than real time to accelerate the test time per file of both long- and short-form programming, then presents results and errors for review. The RTM Manager browser interface gives users easy access for setup and testing feedback, while the ability to test multiple files in a series automatically limits the amount of necessary human intervention.
