1. Introduction
The DTS audio formats are used in a wide variety of entertainment
media formats.
DTS audio emerged in physical media, originating with Laser Disc in
1996 and is a widely used audio format used in Blu-ray discs today.
The next generation of entertainment media formats is now emerging
in the form of downloadable files and streamed media, including the
Digital Entertainment Content Ecosystem (UltraViolet) and other
digital delivery ecosystems currently in development.

Internet-Draft DTS Namespace Identifier February 2014
DTS audio formats are supported in many broadcast standards,
including DVB, ATSC, SCTE, OIPF, HbbTV and the Korean TTA
specifications and are defined for both OTT and broadcast delivery
in many of these specifications.
2. Specifications Template
Namespace ID:
"dts"
Registration information:
Registration Version Number: 1
Registration Date: 2014-02-14
Declared registrant of the namespace:
Name: DTS, Inc.
Address: 5220 Las Virgenes Rd
Calabasas, California, 91301, USA
Contact: Phillip Maness
Phone: +1 818 436 1361

Declaration of structure:
The Namespace Specific String (NSS) of all URNs assigned by
DTS, Inc. will have the following hierarchical structure:
urn:dts:{category}:{string}
where the "category" is a US-ASCII string that conforms to URN
syntax requirements ([RFC2141]), and "{string}" is a string that
confirms to URN syntax requirements ([RFC2141]).
Relevant ancillary documentation:
none

Internet-Draft DTS Namespace Identifier February 2014
Identifier uniqueness considerations:
DTS, Inc. shall establish unique identifiers as appropriate.
Uniqueness is guaranteed as long as the assigned "{category}" is
never reassigned for other categories. DTS, Inc. is responsible
for this.
Identifier persistence considerations:
DTS, Inc. is committed to maintaining the accessibility and
persistence of all resources that are officially assigned URNs by
this organization. Persistence of identifiers is dependent upon
suitable delegation at the level of "category"s, and persistence
of category assignment.
Process of identifier assignment:
All the assignments of identifiers are fully controlled and
managed by DTS, Inc.
Process of identifier resolution:
The namespace is not listed with an RDS; this is not relevant.
Rules for Lexical Equivalence:
The "{category}" is case-insensitive. Thus, the portion of the
URN:
urn:dts:{category}:
is case-insensitive for matches. The remainder of the identifier
shall be considered case-sensitive; hence, URNs are only
lexically equivalent if they are also lexically identical in the
remaining {string} field.
Conformance with URN Syntax:
No special considerations.
Validation mechanism:
Validation shall be done by a syntax grammar corresponding to
each "{category}".
Scope:

Global.
3. Example
The following examples represent hypothetical URNs that could be
assigned by DTS, Inc.
urn:dts:dash:MPDparameter:2014
urn:dts:metadata-example:metaparameter:2014
urn:dts:profile-example:profileparameter:2015
4. Namespace Considerations
The objective of this namespace registration is to facilitate
consistent implementation of DTS across all networked ecosystems.
5. Community Considerations
The names in this namespace are to be used in any public
implementations applying DTS specifications or in the transmission
of DTS bitstreams so anybody can benefit from the officially
assigned namespace.
Potential beneficiary communities include:
a) Implementers of the MPEG DASH specifications using DTS audio.
Resources that comply with the MPEG DASH specifications (including
DASH schemas, instance documents that comply with DASH schemas,
and DASH default Classification Schemes) may, by means of the
registered namespace, become exposed to the general Internet and
gain from the interoperability benefits of the Internet at large.
b) Implementers of other specifications that incorporate components
of the DTS specifications.
URNs used to identify DTS components may be used to enable their
inclusion in, and enhancement of, other specifications while
maintaining, to a certain degree, interoperability with the DTS
implementers community.
c) Implementers of other semantically related specifications that do
not directly incorporate components of the DTS specifications.

Internet-Draft DTS Namespace Identifier February 2014
URNs used to identify components of the DTS specifications, such
as identifiers of terms within default Classification Schemes, may
enable interoperation with other semantically determined
specifications (including present and future metadata/resource
description and ontology specifications) of relevance to audio
codec implementation communities (see a) and b) above).Formal

6. IANA Considerations
The document includes a URN NID registration that is to be entered
into the IANA registry of URN NIDs.
