Introduction

The International Standard ISO/IEC 14496-4:2004/AMD18:2007, published on November 19, 2007, is an amendment to the existing standard for Information technology -- Coding of audio-visual objects -- Part 4: Compatibility testing for MPEG-4 with respect to MPEG-1/2 Audio. This document provides detailed specifications and guidelines to ensure that systems utilizing the Advanced Audio Coding (AAC) layer in conjunction with MPEG-1 or MPEG-2 audio formats meet the necessary criteria for interoperability within the broader framework of ISO/IEC 14496, commonly known as MPEG-4.

This amendment aims to address specific issues related to the integration and testing of MPEG-1 and MPEG-2 audio components within the larger MPEG-4 ecosystem. It outlines a comprehensive set of tests designed to verify the compatibility and consistency of these audio formats with the overall MPEG-4 standard, ensuring that end-users experience seamless playback across different devices and platforms.

The document includes detailed descriptions of test procedures, reference models for expected behavior, and guidelines for implementing corrective measures in cases where inconsistencies are detected. It is intended to be used by developers, system integrators, and quality assurance teams working on MPEG-4-based audio systems, ensuring that their products adhere to the highest standards of interoperability.
