What Is HDMI And How Does It Work?
HDMI, or High-Definition Multimedia Interface, is a digital video interface standard that allows users to transmit high-definition video and audio signals between devices. It works by using a single cable to carry both video and audio signals, making it a convenient and clutter-free way to connect devices such as TVs, projectors, and gaming consoles.
The HDMI standard uses a combination of digital signal processing and compression to transmit high-quality video and audio signals. It supports a wide range of resolutions, including 1080p, 1440p, and 2160p, as well as various audio formats, such as Dolby Digital and DTS. HDMI also supports features like 3D video and ARC (Audio Return Channel), which allows for the transmission of audio signals from a TV back to a soundbar or receiver.
What Are The Main Differences Between HDMI 1 And HDMI 2?
The main differences between HDMI 1 and HDMI 2 lie in their bandwidth and resolution capabilities. HDMI 1, which was introduced in 2002, has a bandwidth of 4.95 Gbps and supports resolutions up to 1080p at 60 Hz. HDMI 2, on the other hand, has a bandwidth of 18 Gbps and supports resolutions up to 2160p at 60 Hz, as well as 4K at 30 Hz.
