Do the comparison for (1) and (2) if same, it is OK. 7.1. What is HDMI? The High-Definition Multimedia Interface (HDMI) is rapidly e

34、merging as the connection standard for HDTV. Developed by Sony, Hitachi, Thomson (RCA), Philips, Matsushita (Panasonic), Toshiba and Silicon Image as the digital interface standard for the consumer electronics market, HDMI combines high-definition video and multi-channel audio in a single digital in

35、terface to provide crystal-clear digital quality over a single cable. One cable for audio and video dramatically simplifies home theater system installation and eliminates the cable mess behind entertainment system components. HDMI offers significant advantages over analog A/V connections, including

36、 the ability to transmit uncompressed digital video and audio content. Hollywood studios and cable and satellite operators support HDMI. HDMI is based on Silicon Images TMDStechnology and is fully backward compatible with PCs and displays incorporating the Digital Visual Interface (DVI) standard, wh

37、ich was also pioneered by Silicon Image. Because it was designed specifically for consumer electronics applications, HDMI offers additional consumer enhancements. Content comes in a variety of sizes, resolutions and formats, and HDMI systems will automatically configure to display content in the mos

38、t effective format. In addition, with a point and click, HDMIs integrated remote capability automatically configures the home theater system on demand, turning on or off the components necessary to view a DVD, listen to a CD or watch cable or satellite TV. 26 SA-XR700EG 7.2.

Main features and benefits All digital provides the highest quality HDMI is the only interface in consumer electronics that can carry both uncompressed high-definition video and uncompressed multi-channel

40、 audio in all HD formats, including 720p, 1080i and even upcoming 1080p. A single cable connection means no more cable mess Since HDMI carries all digital video and audio channels, there is only one cable to connect any HDMI-enabled source device to a display. 7.7. Other features and benefits Automa

41、tic format adjustment matches content to preferred viewing format HDMI systems can automatically configure to display content in its most effective format. If cable TV content jumps from 16:9 format to standard 4:3, an HDMI-enabled TV will automatically adjust to match the ideal format. 28 SA-XR700E

42、G Integrated remote provides simple control of your system HDMI allows CE manufacturers to build intelligence into their devices so that one remote click can configure your entire HDMI- enabled system to turn certain components on or off depending on the specific components that are required. PC Com

43、patibility enables viewing of your PC data on your HDTV HDMI-enabled devices are backwards compatible with the broad array of DVI-based PCs so that you can display gaming or entertainment content on your HDTV. 29 SA-XR700EG 8 Assembling and Disassembling 8.1.
