October 16, 2023 – Video Clarity’s RTM provides full Transmission Path Testing for OTT, Cable, DBS, IPTV, and Broadcast with new ST 2110 and native HDMI input interfaces.
Many titles now originate in UHD for SVOD services and continue to be delivered in HD for broadcast origination. Testing delivered quality accurately for the various types of content creates a significant and on-going project to test the various bit rates and delivery resolutions to the home or inter-facility networks. To simplify video quality testing of differing delivery services and receiver types, Video Clarity’s integrated ST 2110 and HDMI input option for the RTM 4K system or ClearView Extreme Analyzer allows ease of use with highest accuracy full-reference quality metrics for video, audio, and lip sync.
In these examples the RTM 4K system is input with live source content from either an SDI or ST 2100 network as UHD or multiple HD videos with the resulting delivery samples being input from set top boxes or other service path devices. This way the type of network and delivery path is included in the test for a complete end-to-end quality assessment.
-Create quality average data over short or long duration tests
-Set thresholds for quality to find and record low quality events
-Measure PSNR for high bitrate, low loss codec transmissions
-Use DMOS with MS-SSIM metric for human perceptual accuracy to test home service quality
-Apply up to 16 channel audio test per program with millisecond accurate lip-sync test
-Compare different home service delivery paths with real-time video quality monitoring
