Introduced at NAB 2019, HESP leapfrogs current streaming protocols by removing the need for trade-offs between latency, scalability and viewer experience. It delivers sub-second latency, as low as 400ms, at scale, as well as near real-time sub-100ms zapping times. This results in an unparalleled viewing experience over standard HTTP-based Internet infrastructure and CDNs. Notably, HESP also reduces bandwidth costs by as much as 20% compared to current solutions such as the Common Media Application Format (CMAF) combined with chunked transfer encoding (CTE).
 
The HESP Alliance aims to accelerate standardization and large-scale adoption of HESP. Alliance members can license the technology; integrate it into their video packaging and playback solutions; and develop and share extensions to drive further innovation. A certification program for HESP-compliant solutions will ensure interoperability and provide peace of mind for media companies deploying HESP-based streaming services.
 
The first HESP solutions will be available in Q4 2020. They will include an independently developed THEO Technologies HESP-enabled video player and a Synamedia HESP-certified packager. These will be followed by more third-party solutions in 2021, giving operators, broadcasters and OTT streaming services a choice of components.
