V-Nova collaborates with Globo Mediatech Lab to develop an LCEVC stream of the Brazilian Carnival

V-Nova has announced the collaboration with Globo Mediatech Lab in the delivery of an LCEVCenhanced stream for the 2023 Carnival in São Paulo and Rio de Janeiro, Brazil.

The live stream was configured in conjunction with existing AVC/H.264 transmission to demonstrate the benefits of MPEG-5 LCEVC in live streaming applications.

The streaming trial featured a MainConcept LCEVCenhanced H.264 live encoder creating a ladder of 6 profiles peaking at 1080p29.97 @ 4500kbps. This was compared to the incumbent AVC/H.264only channel of 8 profiles, where the top profile was 1080p29.97 @ 5500kbps.

The streaming employed HLS in 6 second TS segments and delivered via AWS CloudFront. Playback was available on a demonstration website using Shaka Player v4.3 which natively includes an LCEVC decoding option.

The LCEVC-enhanced H.264 delivered a high quality output with a ~40% bandwidth saving compared to the existing H.264-only stream.

Guido Meardi, CEO at V-Nova said, “The Carnival is as beautiful to watch as it is challenging to compress at high quality. We are proud of our collaboration with Globo, which proves the tangible benefits of LCEVC for enhancing resolution and picture quality in largescale live events while improving efficiency in both the CDN and backend. Critically, these real-life trials demonstrate that this new technology can be deployed today with broad encoder and decoder support available.”

Deacon Johnson, SVP & General Manager at MainConcept said, “We are pleased to continue the work we started in 2022 with V-Nova and Globo. MainConcept values our partnerships with industry leaders, such as V-Nova and Globo, who share our commitment to the quality, reliability, and performance we demand in our products.” 
