Remember those old leads that you used to plug into your TV sockets as an audio-video input-output? Well, it’s time you forget about them. High Definition Multimedia Interface or HDMI leads are now replacing them like locusts on a farm.
The shift from SCART to HDMI
HDMI leads are now the preferred connection type for high definition TVs, and although HDTVs still come with the old SCART lead ports, the long used SCART is now fast becoming obsolete. On the forefront of digital media connection technology, HDMI leads offer a much better picture and sound quality with just one lead instead of two, as opposed to the conventional SCART cables – which has separate leads for audio and video.
HDMI not only gives better quality and requires fewer wires, but also consumes less power since it directly transmits digital signals from one media to another. Traditionally, signals had to be converted from digital to analogue before transmission and back from analogue to digital after reception into a device. This consumed more power, increased the clock timing and also caused degradation in the picture quality.
HDMI leads transmit picture and sound information in an uncompressed format which maintains the quality of the signals and in addition support standard as well as high definition video, plus multi-channel digital audio on a single cable.
Nowadays computers, Blu-ray players, DVD players, set-top boxes, projectors and more have HDMI ports which make it much more convenient for people than using SCART or component cables.
The superiority of HDMI cables is undeniable and ignoring this would be a mistake. So go ahead, change, renew, update and upgrade.
