Packetization of Dolby Digital Plus bitstreams

This section describes the process of analyzing and preparing a Dolby Digital Plus bitstream for storage within an MPEG-DASH compliant ISO base media file.

As Dolby Digital Plus features a high level of flexibility and potentially complex bitstream configurations, this section defines constraints on Dolby Digital Plus that minimize impact on decoding devices while ensuring that a wide range of applications can be supported. To simplify the design of MPEG-DASH compliant demultiplexers, this section presents a specific method for grouping Dolby Digital Plus frames together for storage within an ISO base media file track sample.
