High Definition TV Explained

HDTV, or high-def TV stands for High Definition Television. It is the relatively new and increasingly more popular type of digital television broadcasting signal that displays TV images in four times as much detail as analogue “standard definition”

Resolution is the main reason why TV pictures look so much better in HDTV than in Standard Definition. On a High Definition television displaying a High Definition signal source, over two million pixels are utilized to create images. As a result, TV pictures displayed in High Definition appear clearer, more vibrant, and have much greater depth. If you are watching a movie in your home theatre system, High Definition can add an extra layer of immersion, while sporting events appear in incredible detail. A recent survey actually revealed that nearly 50% of HDTV owners cited the fantastic quality of HD sports as the reason for their purchase.

High Definition TV provides great audio?

HDTV takes advantage of five separate audio channels, plus a special channel devoted solely to bass. These multiple channels create a rich audio landscape that surrounds viewers, letting them immerse themselves in the viewing experience. Because 5.1 surround sound comes standard with High Definition TV, viewers can experience audio that complements video images in a way that’s not possible with ordinary TV. To achieve this level of sound satisfaction, HDTV shows and events are actually recorded and mixed to put specific sounds in each of HDTV’s five audio channels.

The benefits of having HD sound.

Digital 5.1 or 7.1 Surround Sound Set up

5.1 Five speakers and a sub woofer create the digital 5.1 surround sound landscape. They are positioned front left, right and centre, rear left and right. The “.1” in 5.1 systems signifies the sub woofer used to create bass that’s felt as well as heard. The foundation of the HD sound experience is digital 5.1 surround sound, an encoding, decoding and playback system that produces an aural experience for HDTV viewers that places them squarely in the on-screen action. Together with a 5.1 receiver, HD speakers immerse HDTV viewers in a fully encompassing audio landscape that was created specifically for HD programming.

7.1 same as 5.1 but 2 extra rear speakers.
