During the NAB Show in Las Vegas BBright, an Ultra HD infrastructure and video compression startup, demonstrated its latest cost-effective 4K / UHD technology for Live encoding compatible with Main 10 H.265 profile, up-to 60 fps.
The SLED-4K Live encoder reduces the necessary IP streaming bandwidth to bit rates compatible with real-life applications and existing distribution networks (12-20Mbps range). Full video frame processing is employed to avoid visible tile artefacts. Video quality is optimized for the extreme requirements of satellite and terrestrial broadcast applications, including demanding content types such as live sports.
Built-in redundancy during live operation is supported through ability to swap between multiple blades on the fly. There is also an option for Temporal Scalability (SVC) for compatibility with the some first generation, already existing, 4K STBs.
The SLED-4K appliance is built-on a scalable and field upgradable software distributed architecture on CPU’s, with possible evolutions to HDR (12-bit) and HFR (100/120 fps).
An appliance for Live HEVC encoding in HD/Full-HD is also available as SLED-HD.
UHD-Play is a 4K baseband player with quad 3G-SDI outputs at 4:2:2, 10-bit, at up to 60fps. This product is compatible with multi file formats and provides an alternative source to a live 4K feed. UHD-Play embeds an HD/Full-HD to Ultra HD upscaler after file ingest.
As a French start-up, BBright develops high-end 4K and HEVC technologies including broadcast appliances such as encoders and play-out servers for the video ecosystem. The company is privately held and was founded in September 2013 in Rennes. – Aldo Cugnini
