Question

HDMI interfaces can transmit information including visuals and audio

Answer 1

Answer:

Stands for "High-Definition Multimedia Interface." HDMI is a trademark and brand name for a digital interface used to transmit audio and video data in a single cable. It is supported by modern audio/video equipment, such as 4K televisions, HDTVs, audio receivers, DVD and Blu-ray players, cable boxes, and video game consoles.

While other types of A/V connections require separate cables for audio and video data, a single HDMI cable carries the audio and video streams together, eliminating cable clutter. For example, an analog component cable connection requires three cables for video and two for audio, totaling five cables in all. The same information can be transmitted digitally using one HDMI cable.

Because HDMI is a digital connection, HDMI cables are less prone to interference and signal noise than analog cables. Also, since most components, such as DVD players and digital cable boxes process information digitally, HDMI eliminates the digital-to-analog and analog-to-digital conversion other interfaces require. Therefore, HDMI typically produces the best quality picture and sound compared to other types of connections.

Answer 2

HDMI cables can transfer video and audio in high definition quality from one device to another. There are a variety of reasons you may not be hearing source audio on another device when using an HDMI cable; the settings may not be correct on one of the devices, the hardware may be faulty or the cable itself may be bad.
