3GPP Work Item description

This page contains informal descriptive text only.  See master WID page for further details.

Feature: Dynamic and interactive multimedia scenes

The user experience of multimedia on 3G terminals can be enhanced if the selection, control and display of the multimedia scenes are integrated into a single user interface. Also, it should be possible to update animated applications and displays incrementally in order to use bandwidth appropriately. 

Scene is understood as a presentation of multimedia content including a service logic (animation, menu, links…).

There are existing non-standard solutions in this area which are enjoying some adoption into 3G terminals, but the market and 3G community would benefit greatly from a standard, open, stable, multi-vendor and interoperable specification.
Existing capability in 3GPP specifications is limited to download and progressive download; full incremental update is not possible, and interactivity is limited.  In addition, existing support for compression and binarization is limited.

An update of a piece of content within a multimedia presentation is not possible without reloading a complete page, eg: changing frequently a quote within a stock-exchange service or adding a voting button in an iTV service.

Work Item in OMA and 3GPP:

OMA has approved a WI on Rich-Media Environment. The goal of this WI is to define Rich-Media use cases and requirements for the OMA service enablers.

The present WI defines tasks of 3GPP SA4 to specify the dynamic and interactive multimedia scenes of PSS, MMS, MBMS services relative to SA4 specifications (bearer dependant aspects of service enablers).

Objective:

The present WI defines tasks of 3GPP SA4 to specify the dynamic and interactive multimedia scenes of PSS, MMS, MBMS services relative to SA4 specifications (bearer dependant aspects of service enablers).

To produce a specification for multimedia scene management, including:

    §         scene format and scene definition

    §         container and delivery formats including both file and stream forms

    §         the compatibility with, integration of, and building upon existing media types and formats in 3GPP specifications, including but not limited to video, audio (including both sampled audio and synthetic audio), images and graphics (SVG Tiny),  storage format such as 3GPP file format and stream formats such as RTP.

    §         management of user interactivity

    §         incrementally updated scenes and animations

    §         integration with capabilities for secure/encrypted delivery.

    §         efficient use of the bandwidth of the radio network.

This work item is proposed for release 7.

Service Aspects:

This work will provide a media type, which can be delivered using existing services, and integrated with existing media types.  It therefore enhances any service using multimedia, including: MBMS, PSS (including progressive download), and MMS.  The adoption of this media type into these services is envisaged.
