APB+Video Compression

More video codecs emerge to ease video delivery

Whether it is HEVC/H.265 or the more recently released AV1, there is now a variety of video compression standards available to allow operators to deliver high-quality content in a more cost-effective manner to their audiences

If you are visiting IBC2018 this month, and looking in particular for connectivity solutions for live production, you may be inclined to visit Dejero at booth 11.C15.

As a company, Dejero believes that there is an inexorable shift towards the HEVC/H.265 video compression standard to efficiently transport high-quality video from the field.

Todd Schneider, CTO of Dejero, tells APB: “Dejero has been refining its encoder in low-latency, high-quality live broadcast applications, and you’ll see even better video quality from us at IBC2018.

“We have a multi-faceted roadmap for the improvement of video quality and it’s not just the encoder — the whole system must work in concert to deliver the goods.”

The roadmap is supported by HEVC/H.265 and manifested in solutions such as the Dejero EnGo, which is equipped with increasing processing capability to boost overall performance and deliver enhanced picture quality, according to Schneider, adding: “It combines our industry-leading auto-transport and adaptive bitrate encoding technology with HEVC/H.265 compression.”

He also suggests that in challenging network conditions in a live production environment, HEVC/H.265 “really shines”.

“If you are in a mobile or nomadic scenario and you do not have good connectivity, HEVC/H.265 and the improved compression efficiency it offers can be incredibly useful — ensuring high-quality video even in low-bandwidth environments.”

As to how broadcasters and content producers can most effectively make HEVC/H.265 work in live production, Schneider is keen to highlight that lab measurements of video encoding quality only tell part of the story. Instead, the entire system, which consists of wireless, blending algorithm and the adaptive rate video encoder, must be considered because they all contribute to picture quality. Full story is available in the September 2018 of APB.
