ISO/IEC 14496-5:2001/Amd 41:2019

Overview

ISO/IEC 14496-5:2001/Amd 41:2019 is an internationally recognized standard published by ISO and IEC that focuses on reference software for internet video coding. As an amendment to Part 5 of the ISO/IEC 14496 series, which is dedicated to the coding of audio-visual objects, this update provides reference C-based visual encoder and decoder software tailored specifically for internet video applications. It supports interoperability, facilitates development, and encourages the consistent implementation of video coding techniques optimized for streaming and web-based video environments.

Key Topics

• Reference Software Addition: Amendment 41 introduces specific reference software for internet video coding (IVC) to the existing ISO/IEC 14496-5 framework. This includes:

  • Visual decoder implemented in C language
  • Visual encoder implemented in C language

• Software Integration: The amendment specifies the inclusion of the IVC reference software in the standard's electronic attachment and software database under the path video/natural/IVC_software.

• Standardization Process: Developed by ISO/IEC Joint Technical Committee 1, Subcommittee SC 29, the document adheres to international editorial rules and ensures compliance with ISO patent policies and licensing norms.

• Global Cooperation: Reflects collaborative efforts of national standard bodies and related organizations to enhance video coding standards for internet applications.

Applications

• Internet Video Streaming: The amendment’s reference software supports efficient and standardized video compression and decompression, essential for high-quality streaming over internet networks with variable bandwidth.

• Web-Based Multimedia Services: Enables software developers and system integrators to adopt a common codec foundation, improving cross-platform compatibility for web media players and content delivery networks.

• Video Codec Research and Development: Provides a baseline implementation for industry researchers and developers to test, optimize, and innovate new internet video coding techniques.

• Educational Use: Acts as a valuable resource for learning and demonstrating state-of-the-art video coding methods within academic and training environments.

Related Standards

• ISO/IEC 14496 Series (MPEG-4): The amendment supplements Part 5 of this series, which broadly addresses coding of audio-visual objects including video, audio, and related content formats.

• ISO/IEC 23001: Systems technologies related to multimedia and streaming may complement applications of this standard.

• ISO/IEC 13818 (MPEG-2): Legacy video coding standards that influence contemporary internet video coding frameworks.

• Other Internet Video Coding Standards: Including ongoing developments and proprietary codecs designed for streaming platforms.

This amendment plays a critical role in advancing internet video coding standards by providing accessible and standardized reference software, fostering innovation, and ensuring consistent quality in digital video coding across the internet ecosystem.
