The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have jointly developed a standard known as ISO/IEC 14496-5:2015. This standard focuses on audio coding and compression methods for multimedia content.
Background
With the rapid expansion of digital media and the increasing demand for efficient storage and transmission, there was a need to develop a standardized audio coding format that would ensure interoperability across different platforms and devices. ISO/IEC 14496-5:2015 was created to address this need.
Main Features
ISO/IEC 14496-5:2015 provides a comprehensive set of specifications for audio coding, including:
Flexible Bitrate: The standard supports different bitrates to accommodate various quality and bandwidth requirements.
Object-based Coding: Audio can be encoded, stored, and transmitted as individual objects, allowing for greater flexibility in playback and editing.
Error Resilience: The standard includes error resilience techniques to ensure robustness in the presence of transmission errors.
Enhanced Compression: ISO/IEC 14496-5:2015 utilizes advanced compression algorithms to achieve high-quality audio at lower bitrates.
Benefits and Applications
ISO/IEC 14496-5:2015 offers several benefits and finds applications in various fields, including:
Streaming Services: The standard enables efficient audio streaming over the internet, facilitating the widespread availability of online music and audio content.
Broadcasting: Broadcasters can use ISO/IEC 14496-5:2015 to transmit high-quality audio signals while conserving bandwidth.
Storage: The standard allows for the efficient storage of audio files, maximizing available storage capacity.
Mobile Applications: With its low bitrate requirements, ISO/IEC 14496-5:2015 is suitable for mobile applications, enabling streaming and playback on devices with limited resources.
In conclusion, ISO/IEC 14496-5:2015 is an essential standard that provides specifications for audio coding and compression. Its flexibility, error resilience, and enhanced compression capabilities make it suitable for a wide range of applications in the multimedia industry.
