ISO/IEC 14496-5:2001/Amd 23:2010

Overview

ISO/IEC 14496-5:2001/Amd 23:2010 is an international standard issued by ISO and IEC, focusing on information technology for coding audio-visual objects. This particular amendment, part of the MPEG-4 standard series, introduces synthesized texture reference software under Part 5, which is dedicated to reference software tools. The amendment provides a reference implementation supporting synthesized texture generation, enhancing the capabilities of audio-visual object coding with advanced texture synthesis techniques.

Synthesized textures play a crucial role in video and multimedia coding by enabling more efficient and realistic rendering of visual content without the need for exhaustive storage or transmission of raw texture data. This amendment extends the MPEG-4 Part 5 reference software to include tools and algorithms for synthesized texture processing, facilitating development and interoperability in multimedia applications.

Key Topics

• Reference software for synthesized textures: Implements algorithms for generating textures programmatically, reducing memory and bandwidth requirements in video coding.
• MPEG-4 Part 5 compliance: Builds on the established MPEG-4 framework for coding audio-visual objects with an emphasis on ensuring compatibility and standardization.
• Audio-visual coding enhancements: Provides techniques to support texture synthesis, offering improved visual effects and efficient data representation.
• CD-ROM distribution: Includes the official documentation in PDF format alongside the executable reference software package for synthesized texture, facilitating adoption and evaluation.
• Installation guidelines: Detailed instructions on unzipping and preserving file structure ensure proper installation and functionality of the software tools.
• Intellectual property and licensing: Adheres strictly to copyright and licensing requirements, emphasizing proper usage and distribution of the standard and reference software.

Applications

The ISO/IEC 14496-5:2001/Amd 23:2010 amendment is valuable across multiple domains in multimedia technology and digital video processing, including:

• Video streaming and broadcasting: Efficient texture synthesis enables high-quality visual effects with lower bandwidth consumption.
• Computer graphics and animation: Facilitates realistic texture generation without the need for large texture libraries, optimizing rendering pipelines.
• Virtual and augmented reality (VR/AR): Enhances immersive environments by producing dynamic synthesized textures fitting various scene requirements.
• Multimedia authoring tools: Integrates with MPEG-4 compliant systems for creating enriched audio-visual objects with synthesized texture features.
• Research and development: Serves as a reference platform for developers and researchers exploring advanced texture coding and synthesis methods.

Related Standards

ISO/IEC 14496, also known as MPEG-4, consists of multiple parts that address different aspects of audio-visual coding:

• ISO/IEC 14496-1: Systems – Defines the systems layer for multiplexing and synchronization.
