IBC2013 will see the European debut of Video Clarity’s ClearView Extreme 4K video-quality analysers, which are claimed to provide a new level of input/output capability and performance in subjective picture-quality comparison.
They are capable of interactive playback and comparison of two uncompressed 4K (3840×2160) sequences at 60, 59.94, 50, 30, 29.97, 25, 24 or 23.98Hz in realtime. Users can import and play A/V sequence files to compare processed video to original sources with new 8- and 10-bit high-resolution displays, and also to test for perceptual video quality.
The 3RU system can use: objective metrics, perceptual metrics (JND/DMOS/PEAQ) and subjective viewing modes for quality analysis. It is controlled via a graphical user interface or using a script. It can store up to 89 minutes of 2160 60p or 351 minutes of 1080 60p (both 8-bit, 4:2:2) on its 5TB disk, with a disk bandwidth of almost 2.4GBps.
It has quad HD-SDI/SDI I/O, YPbPr, S-Video and Composite I/O, and HDMI AV Output, plus eight USB 3.0 and two USB 2.0 ports, an eSata port, a 1394A port, and two Gigabit Ethernet ports.
Also new at IBC (stand 2.C57), will be the latest generation of its RTM realtime audio and video monitoring system, the RTM 3G with adaptive bit-rate testing capabilities. This allows users to test the quality of any delivered service bit rate or resolution that is deployed either from broadcast interfaces or IP networks to ensure that service and product performance levels are understood before content and product are offered to the market.
In what is claimed to be a first for the industry, RTM 3G features DMOS, a full-resolution, full-reference-quality human perceptual measurement performed in realtime. DMOS allows users to view a channel’s quality without the complexity of having to set up one or multiple recordings to score the quality. Another RTM 3G multiscreen, multi-resolution testing capability is automatic recording of unacceptable video and audio, a feature that generates quality score logs upon quality measurement threshold breaks. RTM 3G also enables multiple audio and video measurements in one system at the same time, and users should get a high degree of accuracy because recordings are uncompressed.
