ST 429-18 Immersive Cinema Track File and 429-19 Immersive DCP constraints

Building on the work done in 25CSS to create the Immersive Audio Bitstream Essence (SMPTE ST 2098-2) published last year, work was continued in 21DC to create standards based on current practice for packaging and distributing DCPs that contained the 2098-2 Essence.

Description

Building on the work done in 25CSS to create the Immersive Audio Bitstream Essence (SMPTE ST 2098-2) published last year, work was continued in 21DC to create standards based on current practice for packaging and distributing DCPs that contained the 2098-2 Essence. The DCP needed to be functional with existing deployed systems, while also maintaining backward compatibility with existing Dolby ATMOS content and rendering systems. Work was done to create a track file (ST 429-18) that would be compatible with a DCinema CPL (ST 429-7), and concurrently, to create additional constraints for Immersive Audio DCPs (ST 429-19) that would be used in addition to, and maintaining compliance with, current DCP Operation Constraints (ST 429-2). This webcast will explore those topics in depth. ​
