“ The bigger the spatial image, the more efficiency you get in a newer compression”

CREDIT: PREMIER LEAGUE substantial. For major stadiums, a network resilience of 99.999 % is recommended, as any single point of failure could disrupt an event-critical system and undermine the competition’ s integrity.
Achieving the necessary level of resilience involves deploying spatial diversity – sending signals via two geographically separate routes – and using specific industry standards to manage the handover.“ The very best technique to use this is a technique called SMPTE 2022-7, which in technology terms is what we call merging at the RTP layer,” Andy notes.“ That means if you’ ve got two dual diverse physical routes from the location to the destination, then you can apply the technology and it seamlessly merges the two flows.” It ensures that any disruption on one path has no impact on the final signal. As resolutions move towards 4K and beyond, managing the trade-off between bandwidth costs and image quality becomes critical.“ The bigger the spatial image, the more efficiency you get in a newer compression. So if you’ re going 4K, then I would say HEVC is the compression of choice. It will be foolish not to use HEVC for that,” says Andy.
