Multiple HDMI versions have come out since its initial release on April 16, 2022, ushering in greater speeds and performance upgrades. TMDS encoding helps decrease electromagnetic emissions, hits DC balance, and facilitates reliable clock recovery. It employs TMDS (transition-minimized differential signaling) to transmit high-speed serial information.ĭigitally transmitted signals are low-voltage and low-current, making them vulnerable to externalities. HDMI Cable Structure and TechnologyĪn HDMI cable is basically four twisted pairs of shielded copper wires. The digital nature also means signals don’t attenuate as much as analog signals over a stretch. HDMI cables transmit digital signals, which means less electromagnetic interference. But due to their inability to transmit audio signals, they’re no more the standard like HDMI cables. HDMI (High-Definition Multimedia Interface) is an A/V interface that helps send audio and video information across devices, such as TVs, computer monitors, soundbars, game consoles, AV receivers, projectors, etc., using a single HDMI cable.īefore HDMI, digital audio and video interfaces were discrete, with DVI as the video interface and optical cables (and others) handling audio duties.ĭVI cables are not obsolete.
