Explanation:

HDMI stands for High-Definition Multimedia Interface. It is a standard, uncompressed, and all-digital
audio/video interface. HDMI is capable of delivering the highest quality digital video and multichannel digital audio on a single cable. It provides an interface between any audio/video sources,
such as a DVD player or a computer and a digital television (DTV) or video monitor. HDMI transmits
all ATSC HDTV standards and supports 8-channel digital audio, with extra bandwidth to
accommodate future enhancements. HDMI has two types of connectors: Type A and Type B. Type A
and Type B connectors use 19 pins and 29 pins, respectively. The Type B connector is designed for
very high-resolution displays that are expected in near future.
