What is ISO/IEC 23003-4:2015 ?

ISO-IEC 23003-4:2015 and ISO-IEC 23004-1:2015 are two important technical standards developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) respectively. These standards provide a comprehensive approach to efficient audio coding and multimedia metadata representation, respectively.

ISO-IEC 23003-4:2015, also known as MPEG-D USAC, is a method for efficient audio coding that provides high quality audio at low bit rates. This standard specifically focuses on the compression of audio signals, enabling efficient storage and transmission while maintaining perceptual fidelity. The standard defines a set of encoding and decoding techniques that can be used to compress audio data while maintaining the original audio quality.

ISO-IEC 23004-1:2015, on the other hand, is an international standard that specifies a framework for representing, processing, and controlling multimedia metadata. This technical standard provides a set of standardized tools and mechanisms to describe and manipulate multimedia content in a way that is easy to interpret and understand.

The importance of ISO-IEC 23004-1:2015 lies in its ability to provide a standardized method for representing and managing multimedia metadata, making it easier for content creators, distributors, and consumers to share and reuse multimedia content. By providing a common language for representing and managing multimedia metadata, ISO-IEC 23004-1:2015 can help to improve the discoverability, accessibility, and usability of multimedia content.

In conclusion, ISO-IEC 23003-4:2015 and ISO-IEC 23004-1:2015 are two important technical standards that have the potential to revolutionize the way we think about and use multimedia content. By providing a comprehensive approach to efficient audio coding and multimedia metadata representation, these standards can help to improve the quality, accessibility, and discoverability of multimedia content.
