InterDigital Lowers 4K Content Streaming Bandwidth with Perceptual Pre-Filter Solution
By Rory Lidstone, TMCnet Contributing Writer
Wireless research and development company InterDigital (News - Alert) has managed a successful demonstration of its Perceptual Pre-Filter solution for video delivery systems, meaning it is mere steps away from a proper release. The system was demonstrated recently at Mobile World Congress (News - Alert) where it was exposed to a sizeable audience.
The system is said to be a ground-breaking innovation in terms of reducing bandwidth for streaming video. Indeed, during its MWC demonstration, it was able to deliver up to 40 percent bitrate reduction in streaming 4K resolution content without sacrificing quality.
"4K is here, as we've seen major content publishers make commitments to deliver content this year. That means that the challenge of delivering the content with an excellent user experience must be addressed promptly," said Bill Crean, director of Product Management for InterDigital Solutions, in a statement. "Our User Aware (News - Alert) Video product portfolio, including the Perceptual Pre-Filter solution, takes a novel approach to reducing bitrates without impacting video quality."
It would appear that this Perceptual Pre-Filter solution is the very same system InterDigital developed in partnership with DDD Group. This would fit since, just prior to MWC, the companies stated that they were planning to debut their next generation HD and UHD video processing technologies at the show. However, their estimates suggested that their system would deliver bandwidth savings of up to 20 percent, so it seems the demonstration was more successful than anyone had guessed.
What’s really impressive about the results InterDigital managed during its MWC demonstration is that it entered into its agreement with DDD Group as recently as September.
The Perceptual Pre-Filter solution is designed with the science of human visual perception in mind. Put simply, it filters out parts of visual content that the human eye can’t typically see under certain viewing conditions. This allows for the delivery of video at reduced bitrates without affecting perceived quality.
