Cables are an assembly of wires used to carry data and electrical information. All electronic products receive and transfer information through cables connected between them and the port. Different type of cables are designed to connect various electronic devices to each other. Cables used for connecting high-definition media electronic devices simplify digital communication between equipment. They are also referred to as ports, connectors and interfaces in digital communication. HDMI: HDMI or High-Definition Multimedia Interface is a compact audio/video interface designed for transmitting high-definition digital data from an HDMI-compliant source device to a display device. It is considered as an alternative to existing analog video standards. The HDMI founders are 7 electronics manufacturing companies which include Hitachi, Philips, Sony, Toshiba and others. They created the HDMI standard as a set of guidelines to create high-bandwidth connections between digital devices. The current standard can carry 1080p high-definition signals, and it supports eight channels of uncompressed audio. Consumer HDMI products started production in 2003 and it began to appear in consumer electronic products in 2006. Typically, an HDMI cable features 19 pins in the female area of the cable plug and each one has a different function like conversion and transmission of signals, data flow regulation and power supply. The cable comprises of a pair of twisted wires which transmits data. There are five types of HDMI connectors. Type A & B are defined in the HDMI 1.0 specification, type C in the HDMI 1.3 specification, and type D & E in the HDMI 1.4 specification. Type A is the standard size and the most common, Type C is mini and Type D is micro which can be found on smartphones and tablets. Type E is used for automotive applications. HDMI has a wide array of application. It is used to connect Blu-ray Disc and HD DVD players, cable boxes, video game consoles, personal and tablet computers, audio/video players, digital cameras, camcorders and televisions. Analog signals are converted to digital signals by the use of these cables, and this improves the quality of pictures on high-definition televisions. An HDMI cable can cut down on the number of cables required to connect components, and it can even reduce the number of remote controls needed to watch a movie. Latest technological advancements have made it possible to use small HDMI for display devices to match the quality standards of 3D movies. It supports latest protocols defining 3D videos and resolutions above 1080p. When it comes to the length of an HDMI cable length, there is no maximum on how long the cables should be. But it is important to keep in mind that there are chances for signal degradation in longer cables. Due to this, most manufacturers will not produce cables that are more than 16 feet long. Cables used in theatres are usually much longer, but they are generally produced from high-quality materials. Depending upon the length required for the entertainment room, one can pick the quality and size of the HDMI cable.
