What is mobile multimedia

What is Mobile Multimedia?

  • Creating, sharing, discovering and consuming multimedia content anytime and anywhere in a secure way.

  • Communicating via multimedia means in either one-to-one, one-to-many or many-to-many fashion anytime and anywhere in a secure way.

Technological elements of mobile multimedia

Technological Elements of Mobile Multimedia

  • Standards-Centric View:

    • System Architectures (end-to-end service definitions, system-level interface definitions, functional descriptions, etc.)

    • Protocols (data transport, signalling and control)

    • Codecs (audio and visual)

    • Formats (containers, message formats, file formats, etc.)

IMTC Forum – May 2004 – San Jose, California


Effect of technological convergence

Effect of Technological Convergence

  • Digital Convergence widens the scope of ”media” and the way it is accessed.

  • Convergence blurs the boundaries and enables new technological synergies.

    • e.g. Mobility + Broadcasting : DVB-H (“TV in your pocket”)

  • Convergence brings tighter interoperability requirements.

  • Divergence in technological solutions is the last thing desired in such a convergent environment.

IMTC Forum – May 2004 – San Jose, California


The role of standards

The Role of Standards

  • Standards enable the technologicalecosystems to exist with many stakeholders.

  • Openness gives way to mass deployment and at the same time enable interoperability.

  • Standards povide a natural evolution path for technologies, while enabling backward compatibility when necessary.

IMTC Forum – May 2004 – San Jose, California


Interoperability

Interoperability

  • Interoperability is a natural requirement of standards.

  • It is an implementation-centric issue with essential feedback on the standard (e.g. as change requests).

  • Note: High-level of interoperability does NOT necessarily mean high-level of standards compliance! Creation of big interoperable ”islands” must be avoided. This can be achieved by having a close relationship with the standardization bodies!

    • e.g. IMTC PSS-AG: LSs with 3GPP and 3GPP2

Focus 3gpp packet switched streaming service

FOCUS: 3GPP Packet Switched Streaming Service

  • Standardized by 3GPP (mainly by SA WG4)

    • Main Specs: 26.233 (General Description), 26.234 (Protocols and Codecs), 26.244 (3GP File Format)

  • Release History: Release 4 (2001), Release 5 (2002) and Release 6 (2004)

  • 3GPP PSS evolved from being a simple streaming service (Rel.4) to a more advanced one (Rel.6), with backwards compatibility in mind.

  • 3GPP and 3GPP2 work closely to align the two packet switched streaming services from especially protocols and file format perspective.

Evolution of 3gpp pss

Evolution of 3GPP PSS

IMTC Forum – May 2004 – San Jose, California


Main drivers of this evolution

Main drivers of this evolution

  • New technologies (e.g. H.264 (AVC), MBMS)

  • Technological alignment with other Standardization Bodies (e.g. IETF, MPEG, etc.)

  • Increase in bandwidth (new codecs, new profiles and levels)

  • Content & Service Providers’ Needs

    • Media alternatives for different network access scenarios (3GP Server Profile)

    • Adaptation to different network characteristics (3GPP Rate Adaptation)

    • Digital Rights Management (DRM in File Format & transport)

    • Need for statistical information (QoE Protocol)

  • User needs (e.g. clip assets information in 3GP file and in SDP)

IMTC Forum – May 2004 – San Jose, California


Conclusion

Conclusion

  • We’re living in a digitally convergent environment and mobile multimedia is very much affected by this.

  • Standards provide the core means to sustain the technological ecosystem.

  • Interoperability is the natural requirement of such ecosystems.

  • The progress of 3GPP PSS is a good example of Mobile Multimedia Evolution driven by the industry and standardization bodies together.
