Check of HDMI Sound a. Using the DVD AUDIO TEST DISC V-612 and DVD-VIDEO disc with Dolby Digital signal. b. DVD

32、AUDIO TEST DISC V-612 - Track No. 92 (96kHz, 5.1ch). Track No. 40 (Zero) Check the Level and Noise, output from L / C / R / SL / SR / SW / speaker or pin. c. DVD AUDIO TEST DISC V-612 - Track No. 7 (192kHz, 2ch) if this source can be reproduced, it is OK. 3. Check of HDMI Picture a. The picture qual

33、ity of TV is checked by watching that using DVD TEST DISK S-20 or DVD disc with the colour bar signal. b. DVD TEST DISK S-20 - Track No. 2 (Flag of the rising sun) Colour bar disc - Colour bar signal. c. Make on DVD Setup Picture Comfirmed that there are neither distortion nor a noise on the screen.

34、 If it is a picture quality equal when DVD was connected directly to TV, it is OK 22 SA-XR58E / SA-XR58EG 1. Connect directly DVD player to TV. 2. Connect DVD player to set then connect it to TV. 3. Do the comparison for (1) and (2) if same, it is OK. 7.1. What is HDMI? The High-Definition Multimedi

35、a Interface (HDMI) is rapidly emerging 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-chann

36、el audio in a single digital interface 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 an

37、alog A/V connections, including 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 Visu

38、al Interface (DVI) standard, which 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 configur

39、e to display content in the most 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. 23 SA-XR58E

Main features and benefits All digital provides the highest quality HDMI is the only interface in consumer electronics that can carry both uncompressed h

41、igh-definition video and uncompressed multi-channel 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

42、 a display. 7.7. Other features and benefits Automatic 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 automatic

43、ally adjust to match the ideal format. 25 SA-XR58E / SA-XR58EG 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 d

PC Compatibility 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. 26 SA-XR58E / SA-XR58EG 8 Ass
