Mari Silbey, senior editor Cable/Video, reports on LightReading, "InterDigital and Vantrix are teaming up to increase bandwidth efficiency for multiscreen video delivery, promising bandwidth savings of 15% to 50% above improvements already derived from video compression technology. The enhancements come from InterDigital's PerceptFX solution, which has been in the market since 2014. However, setting a new milestone, Vantrix has just announced the integration of PerceptFX with its own open transcoding platform.

"PerceptFX works by filtering raw video, isolating and removing bits of data that are invisible to the human eye. Because the eye can't perceive those bits anyway, InterDigital Inc. (Nasdaq: IDCC) says it can delete them without sacrificing video quality. PerceptFX isn't a full encoding solution, however. It only deals with perceptual pre-processing before handing the content off to an encoder."

Later, she adds, "The integrated technology from Vantrix and InterDigital can be applied both to offline video, like video-on-demand content, and live broadcasts. The two companies will demonstrate the solution in a live transcoding environment at the upcoming CableLabs Summer Conference, and at the International Broadcasting Convention (IBC) in September."
