One of achievements of the SMPTE ST 2110 suite of standards is to bring flexibility and agility to modern IP media systems. However, until now the format of the audio has been mostly static. With the recent publication of SMPTE ST 2110-41 and ST 2127-2, metadata can now be carried alongside the audio allowing adaptation to multiple audio formats. This enables more personalized and accessible services and brings operational benefits. The presentation will explain the opportunities of this transition and present a Paris Olympics case-study that used the first commercial products.
