When it comes to connecting devices to our TVs, projectors, or soundbars, we often come across two terms: HDMI and HDMI AV. While they may seem similar, there are some key differences between them. In this article, we’ll delve into the world of HDMI and HDMI AV, exploring their definitions, features, and applications.
What is HDMI?
HDMI (High-Definition Multimedia Interface) is a digital video interface standard that allows for the transmission of high-definition video and audio signals between devices. It was first introduced in 2002 and has since become the de facto standard for connecting devices such as TVs, projectors, soundbars, and gaming consoles.
HDMI is a digital interface, which means it uses a digital signal to transmit data. This results in a much higher quality video and audio signal compared to analog interfaces like VGA or composite video. HDMI is also a two-way communication interface, allowing devices to communicate with each other and negotiate the best possible video and audio settings.
HDMI Versions
Over the years, HDMI has undergone several revisions, each introducing new features and improvements. The most common HDMI versions are:
- HDMI 1.0: The first version of HDMI, released in 2002, supported up to 1080i resolution and 8-channel audio.
