SSIMWAVE Enables VOD Player Testing

Canadian company SSIMWAVE has enabled content distributors to evaluate video player experiences remotely and objectively and to address subpar video quality issues via a new Player Test feature in its SSIMPLUS VOD MONITOR Inspector.

The Player Test provides source-to-playout visibility – between any two points in the world – into how individual video files appear to the viewer, using the SSIMPLUS 0-100 scoring metric.  As the only algorithm that can accurately mimic actual human vision, the SSIMPLUS score provides streaming and on-demand content distributors with actionable insights into how network conditions such as bitrate, switches between variants and buffer sizes impact the viewer.

The Player Test will be available before the end of 2019, initially evaluating HLS content delivered to players developed on the video.js framework. Support for additional players and video formats will be available in the near future. 

“There are countless data points that show what is happening in the network, but until now there has been no way to understand exactly what they mean to the viewer,” said Dr. Abdul Rehman, CEO and co-founder of SSIMWAVE.  “Our Player Test capability completes the picture by providing a simple, consistent score that shows how video quality has changed from source to playout, giving a clear indication of what the viewer sees.”

VOD MONITOR Inspector is a cloud-based tool that uniquely combines frame-by-frame and pixel-by-pixel analysis of video content with SSIMPLUS. Using the new Player Test functionality, distributors can achieve three-point monitoring ­– at the source; at the output of the encoder, transcoder or packager; and at the player output. The resulting data can enable optimization of profile ladders, content variants and other variables without noticeably impacting the viewer experience.  For example, rather than treating all content equally, distributors can use the SSIMPLUS score to create and test multiple profile ladders or higher or lower quality variants, depending on the type of content being delivered and the device on which it is being viewed.
