What is HDMI and how does it work?
HDMI (High-Definition Multimedia Interface) is a digital audio/video interface that connects devices such as Blu-ray players, gaming consoles, and computers to displays like TVs, monitors, and projectors. It transmits both video and audio signals over a single cable, providing high-quality audio and video output.
HDMI works by transmitting digital signals from the source device to the display device. The signals are transmitted through a cable that contains four twisted pairs of wires, which carry the digital data. The display device then decodes the signal and displays the video and audio output. HDMI has become the standard connection method for most modern devices, offering a convenient and reliable way to connect devices and display high-quality audio and video.
What is HDMI ARC and how does it differ from regular HDMI?
HDMI ARC (Audio Return Channel) is a feature that allows the TV to send audio signals back to an audio device, such as a soundbar or home theater system, over the same HDMI cable that carries the video signal. This eliminates the need for a separate audio cable, simplifying the connection process and reducing clutter.
The main difference between HDMI ARC and regular HDMI is that HDMI ARC allows for the transmission of audio signals in both directions, while regular HDMI only transmits video and audio signals from the source device to the display device.
