HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from a HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.[4] HDMI is a digital replacement for analogue video standards.

In telephony, line hunting (or hunt group) is the method of distributing phone calls from a single telephone number to a group of several phone lines. Specifically, it refers to the process or algorithm used to select which line will receive the call. Hunt groups are supported by some PBX phone systems. Also, some phone companies will provide this feature for a small fee (see also: Centrex). In the tariffs of some telephone companies, one may obtain hunting for free, but forward on busy is a charged service.
