In 2019, Riot Games became the first organization in the world to use JPEG XS compression for a trans-Atlantic remote production, deploying it for the League of Legends World Championship in Paris. Last month, Riot’s Esports Technology Group aimed to take its use of JPEG XS to the next level during the back-to-back League of Legends Mid-Season Invitational (MSI) and Valorant Champions Tour (VCT) Masters Reykjavík events in Iceland — its first in-person events since LoL World Championships in Shanghai in October.


“Originally,” says Scott Adametz, head of Esports Technology Group, Riot Games, “we were planning on this being a test [of JPEG XS] for Iceland; it wasn’t planned to be used for the actual production paths. But the technology worked so well in the test, and we became comfortable enough to decide, the week before the show went on-air, to use it for the live production. XS ended up solving some needs we didn’t even realize we had with regards to transmission delay.”

For many in the industry, the JPEG XS standard represents the next great leap forward in transmission. The codec delivers high-quality compression with ratios up to 10:1 at sub-millisecond latency, and compressed video can be transported using SMPTE ST 2110-22 over WAN (wide-area network). Riot Games’ broadcast team had been using JPEG2000 for several years but has found a wealth of new possibilities for remote production and ultra-fast transmission with JPEG XS, according to Adametz.
