How and why HDMI became the gold standard in broadcasting

High-definition multimedia interface (HDMI) was founded in 2002 by industry leaders in electronics and entertainment, among them Panasonic, Sony, and Toshiba. It quickly won support from major motion picture producers like Fox, Universal, Disney, Warner, and others. HDMI has dramatically improved the television experience. The technology is evolving as enhancements are added to newer versions. Aside from tv sets, HDMI technology can be found in camcorders, computer monitors, and digital still cameras. It has broad business applications.

Released in 2013, HDMI 2.0 quickly caught on, particularly after the introduction of ultra-high-definition television which requires more bandwidth for higher resolution, greater clarity, and faster frame rates. 2.0 also introduced 3D capabilities and smoother synchronization between audio and video.

HDMI 2.1 was introduced a few years ago (2017) but was not installed in tv sets until late 2018. The newer version provides enhanced performance and certain quantifiable improvements.

Which version is right for you? Here’s what you need to know.

Conclusion

HDMI 2.0 moved audiovisual technology forward dramatically in the last decade, establishing a strong presence and improving the viewer experience. It is also widely available as it has been installed in the majority of television sets sold.

HDMI 2.1 is a newer technology that represents a step forward in audiovisual technology. Although now mostly only available to the general public in higher-end newer model tvs, it does feature enhanced features, including improved video performance and audio quality. Additional improvements include smooth and seamless motions and transitions for gaming, movies, and video, higher bandwidth, and higher resolutions; these translate to greater detail and clarity and more support particularly for immersive viewing, gaming, virtual reality, and industrial, business, or scientific applications including medical imaging. As with any technological improvement, we expect its audience and uses to expand in the future as it becomes more available and is further refined.
