Leonardo Chiariglione: Pioneering Innovator and the Journey to MPAI

Leonardo Chiariglione, an Italian engineer born on January 30, 1943, in Almese, Turin province, Piedmont, Italy, has left an indelible mark on the world of multimedia and digital technology. His remarkable journey has not only shaped international technical standards but also led to the creation of the Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) organization. Chiariglione’s lifelong dedication to innovation, standardization, and the advancement of media technologies has redefined the landscape of digital media and artificial intelligence.

Early Life and Education

Chiariglione’s journey began with a solid foundation in education. After completing his classical high school education at Liceo Salesiano Valsalice in Turin, he pursued a master’s degree in electronic engineering at the Polytechnic University of Turin in 1967. His pursuit of knowledge took him to the University of Tokyo, where he earned his Ph.D. degree in 1973. It was during this period that he learned to speak Japanese, showcasing his commitment to cross-cultural understanding and communication.

Career at CSELT and the Birth of MPEG

Chiariglione’s career flourished at CSELT, the corporate research center of the Telecom Italia group, where he held various positions until July 2003. However, his most significant contribution came in 1988 when he co-founded the Moving Picture Experts Group (MPEG). Serving as its chairman from 1988 to 2020, Chiariglione played a pivotal role in shaping the group’s direction and standards.

Under his leadership, MPEG brought together experts from around the world to produce groundbreaking standards that revolutionized the digital audio-visual media landscape. The MPEG-1 and MPEG-2 standards paved the way for the emergence of digital media, transforming how we create, distribute, and consume multimedia content.

Initiatives and Collaborative Projects

Chiariglione’s passion for innovation extended beyond MPEG. He initiated and led several European collaborative projects, including IVICO, COMIS, and EU 625 VADIS. These projects focused on cost-effective integrated video codecs, supporting the development of MPEG-1, and advancing European hardware and software technology for the MPEG-2 standard. Additionally, he founded DAVIC (the Digital Audio-Visual Council) and FIPA (the Foundation for Intelligent Physical Agents) to define internationally agreed-upon technical specifications.

Challenges and Forward Thinking

Chiariglione’s leadership wasn’t without challenges. In 1999, he became the Executive Director of SDMI (the Secure Digital Music Initiative), which aimed to develop specifications for secure digital music delivery technology. Despite his efforts, conflicts within the group hindered progress, underscoring the complex nature of technological standardization.

MPAI: A New Frontier

Chiariglione’s journey took a new turn in 2020 when he founded the Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) organization. MPAI represents the culmination of his vision for integrating artificial intelligence into media coding. It seeks to create standards that leverage AI to enhance data compression, paving the way for new possibilities in digital media and entertainment.

Legacy and Impact

Leonardo Chiariglione’s journey has been defined by a tireless pursuit of innovation and collaboration. His contributions have transformed the way we experience digital media, from pioneering MPEG standards to his recent endeavors with MPAI. His work has earned him numerous accolades, including the IBC John Tucker Award, IEEE Masaru Ibuka Consumer Electronics Award, and IET Faraday Medal.


Leonardo Chiariglione’s life story is a testament to the power of innovation, collaboration, and a relentless commitment to pushing the boundaries of technology. From his early education to his pioneering role in standardization and his creation of MPAI, Chiariglione’s journey has shaped the digital media landscape and continues to inspire future generations of engineers, technologists, and innovators.
