Consumers worldwide are using PCs to create their own collections of music, photos and even video by burning

30、 them onto CDs. But how these collections can be experienced across different devices can be confusing to navigate, time consuming to access for a DVD player, and be incomplete in terms of music information available to the customer. HighMAT offers a solution to this growing consumer problem. HighMA

31、T dramatically improves the digital media experience on consumer electronic devices by delivering a simple, standardized approach that allows consumers who have created personal collections of digital music, photography and video on their PC to: Create a HighMAT CD or DVD which can be easily played

32、back on consumer electronics devices such as CD and DVD players, and car stereos. Move digital media files (using recordable media such as CD-R and CD-RW) between the PC and various playback devices such as CD and DVD players. A new standard for creating personal media on consumer electronic devices

33、, HighMAT enable easier and more seamless interoperability between Windows PCs and devices designed for your living room, or the car. 9 SA-HT680PL 7.3.2. Why take advantage of HighMAT? A Problem Defined:Today, when consumers create their own digital audio, video or photo collections on CD-R or other

34、 physical formats, there are numerous, inconsistent ways that devices read the data. For the consumer, the playback experience can be confusing: A Solution Created: HighMAT delivers a better digital media access experience by creating a standard approach for PCs to structure digital media on various

35、 physical formats and for playback devices to read the data. 7.3.3. Benefits of HighMAT? 10 SA-HT680PL ConventionalHighMAT Even though DVD player is CD-R/RW compatible, the inconsistent ways that various DVD players can read the music or photos files often leads to a confusing and inconsistant playb

This includes products which are JPEG compatible products without HighMAT support. 11 SA-HT680PL HighMAT is now available for CD Burning and in leading DVD Players. HighMAT is a new technology that is now available in

37、leading software and consumer electronic devices to dramatically improve the digital media experience when you create homemade CDs HighMAT delivers a simple, standardized way for PC software and consumer electronics devices to talk to each other and work better together. 12 SA-HT680PL When you creat

38、e your homemade CDs with software that supports HighMAT CD burning, and then play them back on a DVD player that supports HighMAT, you get better, easier navigation. You get folders you can access with a single click of your DVD players remote control. You can view important information about your m

39、usic like full song names, artist titles, album names and genre. And you can get faster startup on your home entertainment device. To enjoy the benefits of HighMAT, all you need is software that supports HighMAT for CD burning of music or photos, as well as a home entertainment device like a DVD pla

40、yer that supports HighMAT for playback.

42、ing the Optical Pickup Unit The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body. Special care must be taken avoid to electrostatic discharge damage when servicing the laser diode. 1. Do not give a considerable shock to the op

43、tical pickup unit as it has an extremely high-precise structure. 2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed from the PCB should be short-circuited with a short pin or a clip. 3. The flexible cable may be cut off if an

44、excessive force is applied to it. Use caution when handling the flexible cable. 4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off the antistatic FPC. 9.2. Cautions to Be Taken When Replacing the Optic

45、al Pickup The flexible cable of the optical pickup unit which was supplied as a component is equipped with a short clip to prevent the laser diode from being damaged due to electrostatic discharge. Remove the short clip before connecting the flexible cable and make sure that the short land is open.

46、(If the flexible cable is short-circuited, remove the solder.) 9.3. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing wor

47、ks under the working environment where grounding works is completed. 9.3.1. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 15 SA-HT680PL 9.3.2. Human body grounding 1. Use the anti-static wrist strap to dis

48、charge the static electricity form your body. 16 SA-HT680PL Some chassis components may have sharp edges. Be careful when disassembling and servicing. 10 Disassembly Main Component Replacement Procedure “ATTENTION SERVICER” 1. This section describes procedures for checking the operation of the major

49、 printed circuit boards and replacing the main components. 2. For assembly after operation checks or replacement, reverse the respective procedures. Special reassembly procedures are described only when required. 3. Select items from the following index when checks or replacement are required.
