Overview (3)
TR-47.2 Digital Video Broadcasting for Handheld (DVB-H) Air Interface Standards
• The TR-47.2 subcommittee developed one key standard that
addresses a number of specifications.
– TIA-1105 – Terrestrial Mobile Multimedia Multicast based on Digital
Video Broadcasting for Handheld Devices System (2006)
Further projects are expected to start in 2008 and a numbers of liaisons
are progressing with other organizations.
4
Strategic Direction
• With deployments of Mobile Multimedia Multicast Systems starting,
the standards created by the subcommittees are at the forefront of
this new emerging market. New standards will be developed to the
meet the new requirements and revisions will be made to address
newly identified enhancements.
• The committee interacts with a number of organizations including
ETSI, 3GPP, DVB Project, Mobile DTV Alliance, and the FLO Forum.
This high level of global cooperation is expected to continue to meet
the growing market needs.
5
Challenges
• Continue to evaluate the additional needs of the stakeholders in a timely
manner based on commercial deployments of Mobile Multimedia
Multicast Systems.
• Maintaining and growing ETSI relationship including additional work in
TR-47.2 for Satellite Hybrid support and reciprocal support from ETSI on
JTC Broadcast, Work Item DTS/JTC-018.
6
Next Steps/Actions
• Revise and/or amend current standards based on early deployments.
• TR-47.1 is revising a number of currently published standards based on
identified new enhancements including TIA-1099, TIA-1103, and TIA1102
• Solidify work plans for support of Satellite Hybrid approaches for
systems. TR-47.2 has identified future work in this area based on liaisons
with ETSI.

Proposed Resolution
• None required from TIA’s perspective
• Will review during GSC-13 Panel discussions.

TR-47 Terrestrial Mobile Multimedia Multicast (TM3)Scope
•
Engineering Committee TR-47 (TM3) is responsible for development and
maintenance of downlink standards for a terrestrial mobile multimedia multicast
[1] system. These standards are intended to be employed by users and
suppliers to promote compatible and interoperable systems to support multicast
audio, video, and data requirements for a wide range of commercial and public
services.
•
The Committee works with other national and international standards development organizations in promoting
standards harmonization. Work items are encouraged that are not duplicative of wireless data services
architecture, interface and protocol development, such as done in 3GPP, 3GPP2 and Open Mobile Alliance,
among others. The Engineering Committee’s focus is on standards for radio interfaces, testing methodologies,
performance and reliability standards, and equipment design guides as they relate to terrestrial mobile
multimedia multicast.
[1] An audio or video communication made to a select group of multiple destinations simultaneously, or two-way communication such as
videoconferencing, teleconferencing, or e-mail.

TR-47.1 TM3 Forward Link Only Air Interface -Scope
•
Subcommittee TR-47.1, TM3 Forward Link Only Air Interface is
responsible for the development and maintenance of downlink standards for
a subclass of terrestrial mobile multimedia multicast (TM3) systems.
•
The subclass is characterized by the combining of the following features, among others, purpose-built,
high spectral efficiency, multiple simultaneous services, layered modulation and service support,
advanced coding, customized transport methods, not limited to Internet Protocol encapsulation, statistical
multiplexing of variable-rate services, high-quality audio, video & data, content protection, multiple
coverage areas (wide and local) within a single RF channel, support different QoS for different services
within a single RF channel and a single service, fast switching time between services, minimized receiver
power consumption without sacrificing the time-diversity performance or the speed of service switching
regardless of the service rate, and a deterministic frame structure based on a time synchronizing signal
such as GPS.
These standards are intended to be employed by users and suppliers to promote compatible and
interoperable systems to support multicast audio, video, and data requirements for a wide range of
commercial and public services.

TR-47.2 TM3 Digital Video Broadcasting for Handheld Air
Interface - Scope
• Subcommittee TR-47.2, TM3 Digital Video Broadcasting for
Handheld Air Interface is responsible for the development and
maintenance of downlink standards for a subclass of terrestrial
mobile multimedia multicast (TM3) systems based on Digital Video
Broadcasting for Handheld devices technology.
•
TR-47.2 specifications encompass, but not limited to transmission system, implementation
guides, validation of transmission systems and appropriate ETSI documents related to
Digital Video Broadcasting for Handheld Devices. These standards are intended to be
employed by users and suppliers to promote compatible and interoperable systems to
support multicast audio, video, and data requirements for a wide range of commercial and
public services.
