![]() The video source of these cameras will need to be up-converted to UHD HDR to be seamlessly integrated into the main production. OBS says that by having natively captured the content in UHD HDR or up-converted to UHD HDR, then down-converted again, the final HD 1080i signal delivered to the RHBs will offer higher quality across all platforms than if produced in a standard HD production.Īlmost all of the content captured will be produced natively in UHD HDR however, OBS will also rely on several specialty cameras that at this time can only operate in HD 1080p SDR. The HDR standard will be Hybrid-Log Gamma (HLG). The UHD production will adhere to the SMPTE 2036-1 standard and follow the 59.94 Hz specification. UHD takers will receive the international signal in UHD HDR, with 5.1.4 audio configuration. For Tokyo, the SMPTE 292 standard is used to allow for bit rates of 1.485 Gbps for the production of the 1080i/59.94 HD-SDI signal (OBS will follow the 59.94 Hz specification). ![]() OBS Venue Technical Operations (VTO) team has developed a set of look-up tables (LUT) in-house to maximise the quality between all cross-conversions (from/to UHD-HD and HDR-SDR).Īs for technical specs, all RHBs will receive the international signal in HD, based on the host city’s HD standards. The full IP infrastructure has been built to support the transport of the UHD HDR signals for the contribution network. “That’s quite a challenging and complex task for an event of the scale of the Olympic Games.” “That has been done together with adding IP capability to our OB fleet, always making sure that we don’t sacrifice any quality in the delivery of the SDR signal,” he says. Isidoro Moreno, OBS, head of engineering, says OBS has been focused on a single HDR/SDR workflow. OBS has created a single HDR/SDR production workflow model that will allow the trucks to generate an HD 1080i SDR output via high-quality conversion from the primary UHD HDR signal. Overall, OBS will utilize a total of 31 Outside Broadcast (OB) vans and 22 fly-away systems that have been specifically designed and fitted-out to meet the new production and distribution requirements. Delivering UHD HDR content requires customized production units and workflows. OBS says setting up a broadcast environment of this scale and complexity is a significant undertaking. But OBS is adopting a new production standard across the board that will see all outputs in UHD, combined with HDR and immersive audio (5.1.4 channels) from the 42 Olympic competition venues (only the production for the seven outside Tennis courts will remain in HD). The Tokyo Olympics IBC will be an innovation hub for the next two weeks.įor example, UHD and HDR have been a part of the past two Olympics via tests at Rio 2016 and PyeongChang 2018.
