V-Nova’s PERSEUS codec passes IRT’s initial video quality-checks

    V-Nova, originator of the high-performance PERSEUS video codec, says it has passed initial video quality tests by Germany’s IRT (Institut für Rundfunktechnik) for HD TV contribution applications.

    The IRT – the respected principal research arm of German-language public service broadcasters – 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 ‘inter’ 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 “commercially valuable increases in efficiency over contribution compression codes AVC-Intra and JPEG2000 at the most widely adopted HD format today, 1080i.” 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 “fundamental in moving PERSEUS from its award-winning NAB 2015 debut to an established commercial “reality” at IBC.”
