Sony STR-GX80ES Technical Background - Page 16

HDMI inputs and switching Home video connections represent a definite hierarchy of picture quality. At the bottom rung of the ladder, almost not worth mentioning, is the RF connection, which conveys a home video signal to your television as TV Channel 3 or 4. Far better is the composite video connection. Better still is S-Video. One of the best analog connections is Y/Pb/Pr component video, which is capable of going beyond conventional 480i Standard Definition signals and supporting 480p and High Definition 720p and 1080i. But the best available connections are in the digital domain. And Sony has been quick to take advantage. Our STR-DA9000ES was one of the first A/V receivers to offer not one, but two Digital Visual Interface (DVI) inputs, with switching between them and a DVI output to the television. On the left, an HDMI plug and its corresponding jack. On the right, an optional DVI-to-HDMI adaptor cable enables you to connect DVI equipment to the STR-DA7100ES receiver, Now the STR-DA7100 goes a giant step further with the High Definition Multimedia Interface (HDMI). Established in September 2003, HDMI is an extension of the DVI digital interface. While DVI is limited to video only, HDMI can transmit uncompressed High Definition digital video and digital audio via a single cable. This greatly simplifies system set-up, replacing as many as ten analog and digital connections with just one cable! In addition to providing 480p, 720p or 1080i, the HDMI output of Sony ES Series DVD players can support digital video in both RGB and Y/Cb/Cr form. ES Receivers v1.0 Page 16
