MPEG-DASH requirements

Mux-37

Ensures that each MP4 sample consists of one Dolby Digital Plus access unit. See Contents of the MP4 sample.

Mux-39

Uses the structure and values for the EC3SampleEntry and EC3SpecificBox boxes, as defined in Annex F of ETSI TS 102 366. See Signaling Dolby Digital Plus bitstreams in an encrypted MPEG-DASH compliant ISO base media file.

Mux-40

When creating an .mp4 file with a Dolby Digital Plus track that contains Dolby Atmos content, uses the extended structure and values for EC3SpecificBox. See Signaling Dolby Digital Plus bitstreams with Dolby Atmos content in an ISO base media format file.

Mux-41

When creating an encrypted MP4 file containing a Dolby Digital Plus track, sets the box header type value for the EC3SampleEntry box to enca. See Signaling Dolby Digital Plus bitstreams in an encrypted MPEG-DASH compliant ISO base media file.

Mux-42

When creating an encrypted MP4 file, places the protection scheme information (sinf) box immediately after the EC3SpecificBox box. See Signaling Dolby Digital Plus bitstreams in an encrypted MPEG-DASH compliant ISO base media file.

Mux-43

When creating an encrypted MP4 file, includes the frma, schm, and schi boxes in the sinf box. See Signaling Dolby Digital Plus bitstreams in an encrypted MPEG-DASH compliant ISO base media file.

Mux-44

When creating an encrypted MP4 file, sets the frma value to ec-3 for Dolby Digital Plus tracks. See Signaling Dolby Digital Plus bitstreams in an encrypted MPEG-DASH compliant ISO base media file.

Mux-45

In the MPD file, the product uses these adaptation set attributes to describe Dolby Digital Plus content: codecs and mimeType. See Adaptation sets.

Mux-46

In the MPD file, sets the codecs attribute value to ec-3 for a Dolby Digital Plus bitstream. See Adaptation sets.

Mux-47

In the MPD file, sets the type element of the mimeType attribute to audio/mp4 for an MP4 file that contains one or more audio tracks, with no accompanying video. See Adaptation sets.

Mux-48

In the MPD file, sets the type element of the mimeType attribute to video/mp4 for an MP4 file that contains one or more video tracks. See Adaptation sets.

Mux-51

A product that includes the accessibility descriptor in the MPD file sets the schemeIdUri attribute to urn:tva:metadata:cs:AudioPurposeCS:2007. See Accessibility descriptor.

Mux-52

A product that includes the accessibility descriptor in the MPD file sets the termID attribute to the type of accessible audio service carried in the bitstream. See Accessibility descriptor.

Mux-53

In the MPD file for Dolby Digital Plus streams that contain Dolby Atmos content, the product includes the SupplementalProperty descriptor to correctly describe attributes of the Dolby Atmos content. See SupplementalProperty descriptor.

Mux-118

In the MPD file, uses the value attribute of the AudioChannelConfiguration descriptor for Dolby Digital Plus bitstreams as specified in schemeIdUri:urn:mpeg:mpegB:cicp:ChannelConfiguration when applicable. See AudioChannelConfiguration descriptor.
