What is HDMI and how does it work as an audio output?
HDMI (High-Definition Multimedia Interface) is a digital interface standard that allows for the transmission of high-definition video and audio signals between devices. As an audio output, HDMI can carry up to 8 channels of uncompressed audio, making it a popular choice for home theaters and surround sound systems. HDMI works by transmitting digital audio signals from a source device, such as a Blu-ray player or game console, to a receiver or soundbar, which then decodes and plays back the audio.
In addition to its high-quality audio capabilities, HDMI also supports various audio formats, including Dolby TrueHD and DTS-HD Master Audio. This means that users can enjoy immersive, surround sound experiences with their favorite movies and TV shows. Furthermore, HDMI’s ability to carry both video and audio signals over a single cable makes it a convenient option for simplifying home entertainment setups.
