- V-Nova PERSEUS enables higher resolution delivery than H.264 while significantly reducing the data rates required.
- Lower data rates mean more users can benefit from a high-definition experience, with improved visual quality across the range.
- Optimised encoding profiles make more efficient use of network resources.
London, September 7, 2016 – V-Nova Ltd., a leading provider of video compression solutions, has published the results of a further independent evaluation of its V-Nova PERSEUS™ video compression technology.
The evaluation was conducted by independent consultancy informitv and was based on the data rates used by a major national telecommunications service provider, tested with a representative range of high-definition video material, including high-action sports coverage and standard test sequences.
Using V-Nova PERSEUS Hybrid compression, informitv was able to produce an optimised set of encoding profiles at higher resolutions, reducing the overall data rates while maintaining or improving picture quality.
- A 1920×1080 pixel PERSEUS Hybrid encoding at 2,000kbps offered equivalent or better visual quality than the 1280×720 H.264 profile at 3,000kbps employed by the service provider.
- PERSEUS enabled 1280×720 encoding at 1,500kbps compared to a 720×408 resolution reference stream at 2,200kbps.
- At 1000kps, a 1280×720 PERSEUS powered encoding offered four times the resolution of the reference stream at a similar data rate.
“PERSEUS enables service providers to offer higher resolution video at lower data rates, without compromising picture quality,” said Dr William Cooper of informitv. “This offers users a better viewing experience, particularly over constrained or variable networks.”
Guido Meardi, V-Nova CEO and Co-Founder, added: “This independent evaluation demonstrates that V-Nova PERSEUS offers significant benefits to operators, not only saving network bandwidth but also enabling a high-definition viewing experience to more users over existing networks.”
PERSEUS Hybrid encoding uses PERSEUS compression in combination with existing standards such as H.264 to turbocharge video delivery using a software plugin for encoders and decoders.
A white paper documenting the results of the informitv evaluation is available from the V‑Nova website.
