V-Nova, originator of the high-performance PERSEUS video codec, says it has passed initial video quality tests by Germanyâ€™s IRT (Institut fÃ¼r Rundfunktechnik) for HD TV contribution applications.
The IRT â€“ the respected principal research arm of German-language public service broadcasters â€“ evaluated PERSEUS against JPEG2000 contribution and production codecs benchmarks at comparable bit-rates.
The results, based on a mixture of objective and subjective evaluations, confirm that PERSEUS offers a substantial improvement compared to JPEG2000 and a quality that challenges H.264-intra-based production codecs such as AVC-Intra (these carry out video compression processing within individual frames, rather than â€˜interâ€™ schemes, where the processing is completed over multiple frames).
The tests were performed on HD interlaced content at 1080i/25.
IRT said that PERSEUS provided â€œcommercially valuable increases in efficiency over contribution compression codes AVC-Intra and JPEG2000 at the most widely adopted HD format today, 1080i.â€ It added that, due to the hierarchical nature of the PERSEUS codec, the benefits would be even larger at higher resolutions such as UHD/4K and higher frame rates such as 1080p50/60.
Eric Achtmann, V-Nova Executive Chairman and co-Founder, said that proving the technology with the most respected broadcasting organisations was â€œfundamental in moving PERSEUS from its award-winning NAB 2015 debut to an established commercial â€œrealityâ€ at IBC.â€
