NAB 2014 display reveals patented Perception Optimized Processing™ that trims excess data to lower video bit rates up to 50 percent for live and VOD encoded streams with excellent visual quality.

How CRUNCH works

Cinova CRUNCH Reduces Bitrates of Encoded Video

CRUNCH picks up where encoders stop, analyzing their video output in real-time and removing this data that the human eye can’t detect.

Cinova (NAB booth C2453C) will break new ground at NAB 2014 with the introduction of CRUNCH™, the world’s first compressed-domain Stream Optimizer. CRUNCH enhances the existing fixed and adaptive bitrate H.264/AVC video encoding workflows used by live and video on demand content and service providers using its patented Perception Optimized Processing (POP). POP trims visually extraneous data from encoded video streams to reduce bit rates by as much as 50% compared to AVC encoding alone. The dramatic bitrate reduction allows Over the Top (OTT), mobile and other video services to deliver high quality, full resolution video streams that require less bandwidth, use less storage, and can be delivered to viewers at the best quality and with greater reliability.

Cinova CEO and founder Anurag Mendhekar said, “Video encoders do a great job of reducing video to manageable, consistent fixed bit-rates. That consistency is also the limitation of encoders, which end up leaving behind information that is visually extraneous to human perception. CRUNCH picks up where encoders stop, analyzing their video output in real-time and removing this data that the human eye can’t detect. The resulting CRUNCH-ed stream is visually indistinguishable from the encoder’s output stream and requires no changes to viewing devices, but uses a staggering 20-50 percent less bandwidth.”

The benefits of CRUNCH stream optimization include:

  •     Lower delivery costs by reducing bit rates, reducing the number of resource-expensive encodes required in adaptive bit rate processing, and lowering storage requirements
  •     Improved video quality by enabling delivery of higher resolutions at the same or lower bit-rates than in conventional, encode-only workflows
  •     Enhanced viewer experience with higher resolutions, reduced usage of mobile data plans, and fewer stream stutters, freezes and crashes.

Perception Optimized Processing (POP) is a patented technique developed by Cinova engineers that performs on-the-fly visual analysis of every macro-block in a video stream and applies sophisticated yet fast compressed-domain transformation algorithms to eliminate visually extraneous information. By eliminating only data that is unusable by the human eye, CRUNCH reduces the size of the video stream without compromising visual quality.

CRUNCH will work with any encoded stream for any delivery network--content providers, services providers, network operators, as well as other video applications. CRUNCH installation takes only a few hours. The lightweight software runs on inexpensive, commodity Intel Core i7 processor based systems running Mac OS, Linux or Windows for flexible deployment downstream of any existing MPEG-4/AVC encoders. It is used in addition to, not in place of, existing encoding systems, and prior to DRM encryption.

The same POP technology has also been applied to digital photos where it delivers up to 90% reductions in image file sizes and has been used to process more than 10 billion online photos to reduce the storage footprint for photography sites.
