Overview
ISO/IEC 14496-5:2001/Amd 11:2007 is an amendment to the international standard that focuses on reference software for the coding of audio-visual objects, specifically enhancing MPEG-J GFX reference software. Developed by ISO/IEC JTC 1/SC 29, this amendment provides software tools and source code to support the implementation of MPEG-J graphics within multimedia systems. The amendment introduces two distinct MPEG-J GFX reference software packages-one integrated with MPEG-4 Systems and another independent implementation compatible with Java 2 Standard Edition (J2SE) and Java 2 Micro Edition (J2ME).
Key Topics
-
MPEG-J GFX Reference Software
This amendment adds a dedicated clause (Clause 6) detailing the MPEG-J GFX reference software, including separate implementations:
- MPEG-4 Systems dependent package integrated with IM1 and MPEG-4 Systems.
- MPEG-4 Systems independent package designed for J2SE and J2ME environments.
-
Software Architecture and Components
The package includes comprehensive components:
- Java source codes for MPEG-J player functionality.
- Native code implementations in C/C++ for multimedia engines and OpenGL ES renderers.
- Conformance test sources for verifying compliance in both J2SE and J2ME environments.
- Utilities, documentation, and project files to streamline development and integration.
-
Java Platform Support
Support is provided for:
- Java 2 Standard Edition (J2SE), featuring Eclipse and ANT build files for easy compilation and execution.
- Java 2 Micro Edition (J2ME) with modifications to CLDC 1.1 and MIDP 2.0 frameworks for mobile multimedia applications.
-
Integration and Extension
The amendment extends existing MPEG-J capabilities by introducing updated source files, new interfaces, and enhanced user data processing within the MPEG-J environment. Additional improvements include resource management, dynamic capability handling, and advanced rendering components.
Applications
ISO/IEC 14496-5:2001/Amd 11:2007 is crucial for developers and system integrators working in:
-
Multimedia and Audio-Visual System Development
