This session shares the experiences of two broadcasters as they trialled new technologies into their production workflows. The session took place at IBC2023 at the RAI, Amsterdam on Friday 15 September. These three papers are available to download via the links below.

During the FIFA World Cup 2022, Globo along with its technical partners, ran trials to test and showcase (i) the use MPEG-5 Part 2 – LCEVC to deliver legacy receiver compatible HDR over DTT, (ii) DASH live streamed 4K HDR video with immersive and personalized 5.1+4H audio, encoded with VVC, LCEVC and MPEG-H audio, and (iii) evaluation of the interactivity and personalization features provide by the authored MPEG-H Audio content in a Big Screen setting. NHK describes the trials, tools, and systems they put in place to incorporate Next Generation Audio into their live workflows. This also includes a detailed disclosure of a loudness measurement system, developed using both objective and subjective testing. This session is supported by two further papers; AWS assesses the sustainability of cloud-based media platforms providing a useful overview of initiatives underway in the industry. And a further paper from NHK which details their experience in building an NGA playout and recording system.
