for timed graphics. Additionally, the following contraints apply for multiview stereoscopic 3D video bitstreams, if
present in a media presentation:
The DASH multiple views scheme as defined in 5.8.5.6 of ISO/IEC 23009-1 [34] shall be used in the MPD.
One of the following shall be true:
• The base view of the stereoscopic multiview bitstream shall be a complementary representation and the
non-base view of the bitstream shall be a dependent representation. The @dependencyId attribute as
specified in 5.3.5.2 of ISO/IEC 23009-1 [34] shall be used to indicate the complementary and
dependent representations.
• The base view and the non-base view of the stereoscopic multiview bitstream shall reside in the same
representation. The SubRepresentation element shall be used for the representation, and the base view
and the non-base view shall form separate sub-representations. The @level and @dependencyLevel
attributes within the SubRepresentation element shall be used. The Level Assignment box shall be used.
For each leaf segment index, that is, each Segment Index box that indexes only subsegments but not
other Segment index boxes, there shall be exactly one Subsegment Index box.
7.3.5 3GP-DASH Release 11 frame-packed stereoscopic 3D video profile
The 3GP-DASH Release 11 frame-packed stereoscopic 3D video profile is identified by the URN
'urn:3GPP:PSS:profile:DASH11:FPS3D'.
The @mimeType attribute of each Representation shall be provided according to RFC4337. Additional parameters may
be added according to RFC6381 [26].
This profile includes all features defined in clauses 7.3.3.3, 8, 9 and 10.
3GP-DASH Release 11 frame-packed stereoscopic 3D video profile clients shall support frame-packed stereoscopic 3D
video as specified in clause 7.4 of TS 26.234 [3]. For any other particular continuous media type, the corresponding
media decoders are specified in TS 26.234 [3], clause 7.2 for speech, 7.3 for audio, 7.4 for video, 7.9 for timed text and
7.11 for timed graphics. Additionally, the following contraints apply for frame-packed stereoscopic 3D video
bitstreams, if present in a media presentation:
The FramePacking element as defined in clause 8.4.3.2 shall be used in the MPD.
8 DASH - Media Presentation
8.1 Introduction
A Media Presentation is a structured collection of data that is accessible to a 3GP-DASH client to provide a streaming
service to the user.
3GP-DASH is intended to support a media-streaming model for delivery of media content in which control of the
delivery lies exclusively with the client. Clients may request data using the HTTP protocol from standard web servers
that have no 3GP-DASH-specific capabilities. Consequently, this standard focuses not on client or server procedures
but on the data formats used to provide a DASH Media Presentation.
The collection of encoded and deliverable versions of media content and the appropriate description of these form a
Media Presentation. Media content is composed of a single or multiple contiguous media content periods in time. Each
media content period is composed of one or multiple media content components, for example audio components in
various languages and a video component. Each media content component has an assigned media content component
type, for example audio or video.
Each media content component may have several encoded versions, referred to as media streams. Each media stream
inherits the properties of the media content, the media content period, the media content component from which it was
encoded and in addition it gets assigned the properties of the encoding process such as sub-sampling, codec parameters,
