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. Answer option B is incorrect. S-Video, also known as Y/C video, stands for Super-Video. It is a technology for video transmission. Using this technology, the video is transmitted into two separate signals. One is used for color, and the other for brightness. Sometimes S-Video signals are considered as a type of component video signal. However, its quality is inferior to other complex component video schemes such as RGB. This technology produces sharper images than those produced by composite video, which carries the entire set of signals in a single line. For using SVideo, the device sending the signal must support S-Video output and the device receiving the signal needs to have an S-Video input jack. Answer option A is incorrect. DVI stands for Digital Visual Interface. It is a standard for high speed, high resolution digital display invented by Digital Display Working Group (DDWG). DVI accommodates analog and digital interfaces with a single connector. New video cards have DVI as well as VGA ports built into them. Most of LCD monitors come with a 15-pin VGA connection cable, even if they are capable of handling digital signals coming from DVI connections. However, some monitors come with both types of cables. DVI has three main categories of connectors. They are. DVI-A, DVI-D, and DVI-I. DVI-A is an analog-only connector, DVI-D is a digital-only connector, and DVI-I is an analog/digital connector. DVI-D and DVI-I connectors are of two types. single link and dual link. DVI supports UXGA and HDTV with a single set of links. Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual links. Answer option C is incorrect. A VGA or SVGA connector is a 15-pin, three rows, female connector, on the back of a PC used for connecting monitors. http.//en.wikipedia.org/wiki/High- Definition_Multimedia_Interface
