New research finds environmental approach to video compression improves video codec performance

According to new research from nScreenMedia, environmental preprocessing of video can help traditional video codecs improve performance by 12% to 30%. These additional savings can have a dramatic impact on the reach of online video. For example, a 10% savings in streaming bandwidth would allow an additional 26M households worldwide to receive Ultra HD video on their existing broadband connection.

In the new free white paper, Optimizing Video Delivery: Why the Viewing Environment Matters, nScreenMedia examines how traditional video codecs work and contrasts it against environmental pre-processing approaches. The paper explains how the mechanics of vision can be leveraged to identify and remove details in an image that cannot be perceived by a viewer in a specific viewing situation. The paper covers:

  •     The expected growth in fixed and mobile video
  •     The impact of incremental improvements in compression on the video ecosystem
  •     How traditional and environmental compression techniques work
  •     The savings provided by environmental pre-processing techniques over codecs like HEVC alone.

“With Internet video bandwidth forecast to quadruple in 4 years and mobile video bandwidth to increase tenfold in the next 5 years, finding ways to save streaming bandwidth is essential,” said Colin Dixon, Founder and Chief Analyst of nScreenMedia. “Taking into account the mechanics of vision and the specific environment in which a video is consumed can help expand an OTT video service’s reach and save the operator money.”

Taking into account the specific viewing environment of video is a huge untapped opportunity. According to William Crean, Director of Product Management at InterDigital, the sponsor of the research, “Traditional codecs like H.264 and HEVC do a great job of attacking the general problem of video compression, but environmental techniques can improve their performance dramatically by optimizing the experience of a video for a specific set of viewers, devices and viewing locales.”

nScreenMedia’s white paper, Optimizing Video Delivery: Why the Viewing Environment Matters, explains in layman’s terms how environmental pre-processing works and the beneficial impact the additional bandwidth savings will have on every part of the video delivery value chain. The report is available immediately for free from the nScreenMedia website.
