LCEVC cuts bitrate 30-55% and lands in Brazil’s TV 3.0
This article details how MPEG-5 LCEVC enhances existing video codecs, providing 30-55% bitrate reductions across various established standards and reducing transcoding costs. It highlights Brazil's TV 3.0 (DTV+) initiative as the first national broadcast standard to mandate LCEVC, achieving 4K HDR at under 10 Mbps by combining VVC with LCEVC. The technology's application also extends to streaming, pay TV, cloud gaming, and ATSC 3.0 deployments in the US.
Key Takeaways
- MPEG-5 LCEVC works as an enhancement layer for H.264/AVC, HEVC, AV1, and VVC instead of replacing them.
- MPEG validation in 2021 found 46% bitrate savings with H.264/AVC and 31% with HEVC for UHD content.
- Brazil’s TV 3.0 decree, signed by President Lula on August 27, 2025, made LCEVC mandatory in the national broadcast standard.
- Globo used the full TV 3.0 stack during the Paris 2024 Olympics, with UHD feeds encoded at 10 Mbps and decoded on Hisense TVs and Realtek and Amlogic set-top boxes.
- The article says LCEVC can reduce transcoding costs and energy consumption by up to 70% for streaming and OTT platforms, and cut bitrate needs for 4K HDR in US ATSC 3.0 deployments by up to 40%.
Why It Matters
LCEVC is being positioned as a way to improve compression without forcing a codec replacement cycle. That matters because the article ties it to existing encoding pipelines, installed devices, and software updates rather than hardware refreshes. The broader ecosystem angle is Brazil’s TV 3.0 rollout, plus references to streaming, pay TV, cloud gaming, and ATSC 3.0, which suggests the standard is moving beyond broadcast theory into multiple delivery stacks. What to watch next: commercial TV 3.0 services tied to the 2026 World Cup, and whether US ATSC 3.0 deployments begin using the LCEVC support already included in A/345.
