DEVICE INTEROPERABILITY GUIDELINES –
Part 2: DLNA media formats
1 Scope
This part of IEC 62481 specifies the DLNA media format profiles applicable to IEC 62481-1.
Media format profiles are defined for each of the following media classes: audio, image, and
AV. In addition, profile ID values that identify media collections and printer XHTML documents
are also introduced.
It is envisioned that in the home network environment, devices will be capable of exchanging
content items that originate from different sources. Content items will typically come encoded
in different formats. The term "format" designates the compression and encoding tools utilized
to generate the binary instance of a content item, which will be eventually exchanged over the
home network using streaming or file transfer protocols. Examples of formats include MPEG-2,
MPEG-4, WMV and others for video; or MP3, AAC, WMA and others for audio.
Formats alone, however, include as part of their specifications, multiple parameters, features
and tools which can be used in a myriad of combinations to generate content binaries. In this
standard, the notion of a format profile is introduced to identify a particular suitable
combination of format parameters which define a way for representing content binaries. A
format like MPEG-2, for example, can have multiple profiles depending on selections for the
companion audio, the system-layer multiplexing specifications, allowed frame resolutions,
allowed aspect ratios, allowed bit rates, etc.
This standard provides a quasi-exhaustive list of broadly-used format profiles for image, audio,
and AV formats. For each particular format profile, this standard defines a profile ID text token
to be used during the DLNA media discovery and media transfer operations. The profile ID is
exposed in a server's content directory service (CDS) to signal to potential networked players
or renderers the existence of a content item with particular coding and compression features
defined precisely by the item's profile ID. This standard also describes the uses of format
profiles which define media collections and printer XHTML documents.
The number of potential combinations for suitable profiles becomes large rather quickly, as
evidenced by the long profile lists observed in the different sections of this standard.
Consequently, this standard introduces the notion of mandatory profiles, supported by all
devices, as a means to provide baseline content interoperability in the home. Servers have to
be capable of exposing and transferring mandatory profiles while players and renderers have
to be capable of decoding and rendering the mandatory profiles. Unfortunately, mandatory
format profiles cannot be defined universally to suit all scenarios. For this reason, the
definition of mandatory profiles is made taking into account the geographical region and the
target device category.

3.1.62
personal digital assistant
PDA
small electronic device used to store calendar information, contacs, etc.
3.1.63
profile parameter set
collection of compression, encoding, and encapsulation parameters that results in a valid
object binary
NOTE Each media format profile defined in these guidelines is identified by its profile ID. Each profile is defined
selecting a subset of compression parameters, encoding parameters, and file format (or encapsulation) parameters.
The implementer chooses certain parameters to produce a content object binary.
3.1.64
quality of service
QoS
quality of service to provide guarantees on the ability of a network to deliver predictable
results
3.1.65
quarter VGA
QVGA
display format used in digital cameras
3.1.66
render
function which reproduces the encoded content binary in a recognizable manner. The
reproduction process may adjust the features of the content binary to the output
characteristics of the device; for example, an A/V bitstream in high definition may be
readjusted into SD resolution for display in standard definition TV
3.1.67
rendering endpoints
content receiver devices with the capability of rendering the content they receive. These
devices could play the content at the time of the transfer, right after the transfer has finished,
or at a later time after the transfer has finished
NOTE For the purposes of this standard, devices in the following device classes constitute the only known
rendering endpoints: DMP, DMR, DMPr, MDMP, MDMD.
3.1.68
red green blue
RGB
colour composition scheme used by AV devices
3.1.69
real time transport protocol
RTP
media transport that provides end-to-end network transport functions for transmitting real-time
data, such as AV and provides services such as payload type identification, sequence
numbering, time-stamping, and delivery monitoring
3.1.70
standard definition
SD
picture quality at a SDTV level
– 16 – 62481-2 © IEC:2007(E)
3.1.71
standard definition television
SDTV
mode of operation of digital television that provides standard quality display, with a vertical
resolution display less than 720p and an aspect ration of 4:3, resulting in a viewing
experience similar or slightly better than today's analogue television
3.1.72
serving endpoints
content source devices with the capability of making content available to any client device in
the home network. In order to make content available to other home devices, content source
devices act as UPnP media servers
NOTE For the purposes of this standard, devices in the following device classes constitute the only known serving
endpoints: DMS, MDMS. It should be noticed that an uploader device (MDMU) does not constitute a serving
endpoint although it acts as a content source device.
3.1.73
service information (in DVB specifications)
SI
system information (in SCTE specifications)
3.1.74
single program transport stream
MPEG transport stream containing a single program
3.1.75
selection information table
SIT
service(s) and event(s) carried by a partial TS
3.1.76
source of an XHTML-Print document
term describing the DLNA entity that creates the XHTML-Print document for the purpose of
printing. Devices that include a Printer Controller (+PR1+) can act as the source of XHTML-
Print documents. An XHTML-Print document will be pulled by a DMPr from this source entity,
or it will be pushed by this source entity to a DMPr.
3.1.77
system or systems
term referring to the encapsulation and multiplexing protocol that allows the delivery of audio,
and audio/video streams in the context of media formats. This layer provides rules for
identifying individual audio and video components, rules for synchronizing audio and video
components, and others
3.1.78
tolerance
term when used as a noun or as a verb indicates that when a particular endpoint (serving or
rendering or even an intermediate device) receive data packets, the endpoint must be tolerant
of information that it may not understand. A tolerant behaviour implies that the endpoint must
be capable of decoding, parsing, and gracefully ignoring information that is not understood
3.1.79
transport alignment position
position in the bitstream defined for transport alignment
3.1.80
transport stream
collection of multiplexed audio, video, and data packets organized in one or more programs
(or services) in compliance with the MPEG-2 systems specifications
62481-2 © IEC:2007(E) – 17 –
3.1.81
uploading endpoints
content source devices with the capability of uploading content to certain devices in the home
network. In this case, these devices cannot serve to any potential client devices in the
network. Instead they transfer content only to those devices capable of receiving uploads. A
device that belongs to the MDMU device class, or a device that implements the +UP+
capability constitute uploading endpoints
3.1.82
universal plug and play
UPnP
organization that defines some of the foundation standards for DLNA
