The graph below plots PSNR values at different quality settings for a reference video comprising a selection of intricate detail and easy-to-encode scenes. With PCoIP Ultra enhancements, you can choose to move the dial on image quality far beyond the default Q80 setting. It is not difficult to find independent research, such as this report on remote access protocols for DaaS solutions *, that plots PCoIP quality at a higher value for video playback than alternatives such as ICA, RDP or VNC (in this instance, even at the modest default Q80 configuration used by PCoIP technology in Amazon Workspaces). The image quality delivered by PCoIP technology has always been a corner pin of Teradici success. The good news is that capacity is growing, and we want to be ready to leverage that with PCoIP Ultra technology – especially in broadcast and post-production where pristine image reproduction can be critical to line-of-business workflows. I mention ‘future impact’ of PCoIP Ultra because even a modest 1080p 60 fps video workload delivered uncompressed at 24 bits-per-RGB-pixel requires several gigabits of network capacity. To date, the ability to deliver lossless video has only been achievable with technologies such as Serial Digital Interface (SDI) leveraging dedicated cabling – although there is a slow move towards IP network alternatives with lightweight compression. PCoIP Ultra: Ready to leverage more network capacity PCoIP Ultra TM Technical Series Part 7: Setting New Boundaries for Image Quality Heads-up (and a very Canadian sorry!), this section gets a little technical in places…. In this final post, I’ll touch on a subtle enhancement in our protocol which is sure to have significant impact in the future – the ability for the image encoder to operate continuously across the quality spectrum from narrowband WAN, through professional-grade user experience all the way up to every frame delivered at lossless reproduction.
