The CEC signal enables the use of a single remote control to operate all the connected devices. HDMI cables also carry a Consumer Electronics Control (CEC) signal that allows HDMI-connected devices to control each other. This versatility allows the user to simplify their setup by using only one cable for both audio and video without sacrificing signal quality. Unlike the DVI interface that came before it, HDMI can send uncompressed video signals along with either compressed or uncompressed audio signals using a single cable (DVI could only send video). HDMI stands for “High Definition Multimedia Interface.” Just as the name suggests, HDMI functions by passing high-quality audio and video signals. HDMI is the gold standard today, but not all HDMI cables are created equal. Fortunately, as we move into an increasingly digital world, options are getting simpler and more straightforward, so a little information can go a long way towards clarifying your best choice.
