If you want better video and audio quality, then check out HDMI. What is HDMI? It stands for High-Definition Multimedia Interface. This is a compact audiovisual connector that transmits uncompressed digital data. They are known to yield clear picture and sound qualities much better than analog interfaces. HDMI is present in many digital devices from mobile phones to personal computers. This digital interface can carry a bandwidth of 5 Gbps. This is almost twice the amount of traditional interfaces like the S-Video, component video and composite video. Analog connectors suffer from the loss of data for some of their data transmissions — resulting in a poorly-delivered picture and audio signal. Analogs convert the digital source into less precise analog data and then converted again to digital when shown on screen. HDMI eliminated this digital-to-analog conversion process. It retains the digital source with near-zero interruptions in data transmission. The result is excellent quality in picture and audio.
Old connection interfaces require separate cables for audio and video. What you got now is a mess of tangled cables. HDMI, with its large space of video and audio channels, can transmit both audio and video data without compromising quality. This shortens the hooking up process by using very few cables.
Standard HDMI comes in two types: A, with 19 wires and B with 29 wires. This digital interface is compatible with DVI or Digital Video Interface technology. There is a DVI/HDMI cable that merges these two technologies. For better data quality, it is strongly advised that your HDMI connector should exceed 5 meters.
