What is HDMI and how does it work?
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 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, monitors, and projectors to sources like computers, gaming consoles, and Blu-ray players.
HDMI uses a combination of digital signal processing and compression to transmit high-quality video and audio signals. The signal is transmitted through a series of packets, each containing a portion of the video and audio data. The receiving device then reassembles the packets to create the final image and sound. HDMI also supports a range of resolutions, from standard definition to 4K and beyond, making it a versatile and widely-used interface standard.
