12、oFans.CN TERMINOLOGY Terminology Since they share some of the characteristics and technology of CD players, many of the terms and operational concepts used in a DVD player are similar to what you may be familiar with from CD players and changers, or older video disc formats such as Laser Disc. Howev

13、er, if this is your first DVD product, some of the terms used to describe the features of a DVD player may be unfamiliar. The following explanations should solve some of the mysteries of DVD, and help you to enjoy all the power and flexibility of the DVD format and the DVD. With the arrival of DVD,

14、disc data capacity has increased dramatically. On a DVD Video disc most of this capacity is taken up by MPEG 2 video and the multichannel movie soundtrack in Dolby Digital and/or DTS.This information is compressed. Aspect Ratio: This is a description of the width of a video image in relation to its

15、height.A con- ventional video screen is four units wide for every three units of height, thats why the ratio is called ”4:3”. Newer wide aspect ratio video displays are 16 units wide for every nine units of height, making them more like the screen in a movie the- ater.The program material on a DVD m

16、ay be recorded in either format and, in addition, you may configure the DVD to play back in either for- mat, depending on the features recorded on a disc. Title: For a DVD,a title is defined as an entire movie or program.There can be as many chapters within a title as the producers decide to include

17、. Most discs include only one title,but some may have more than one,to give you a “Double Feature”presentation. Chapter: DVD programs are divided into chap- ters and titles. Chapters are the sub-sections pro- grammed into a single title on a disc. Chapters may be compared to the individual tracks on

18、 an audio CD. RGB Video:This is a new form of video signal that eliminates many of the artifacts of traditional composite video signals by splitting the signal into the three fundamental colors Red, Green and Blue (RGB).With an RGB connection (via SCART), you will see greater picture resolution and

19、elimi- nate many picture imperfections such as the moir patterns often seen on checkered pat- terned cloths. However, in order to benefit from RGB video, you must have a video display with an RGB compatible SCART input. Progressive scan: DVD offers progressive scan video outputs for use with compati

20、ble high-reso- lution televisions and projectors.Before DVD,no consumer medium could store,transmit or display video with full resolution.To conserve bandwidth, analog compression (interlacing) is employed:first the odd-numbered lines of a frame are displayed, followed by the even-numbered lines.The

21、 result is that only half of the video image is drawn at one time;the viewers brain must reassemble the com- plete image.This is acceptable,if the monitor is not too large and if there is not too much motion in the image.Large displays and fast-moving images reveal the limitations of this system. Th

22、anks to DVDs immense data capacity,images are now stored intact (progressively),so that all the lines in each frame (odd and even) are shown at the same time.But because most TVs cannot handle a progressive signal,all current DVD play- ers generate an interlaced output for compatibili- ty.Now,the Ha

23、rman Kardon DVD is among the select few DVD players with true progressive scan video output (NTSC and PAL) for use with com- patible TVs and CRT projectors and with all plas- ma,LCD and DLP display devices via the compo- nent video output.The result is 40% greater light output than a conventional TV

24、 and a stunningly detailed high definition image,along with an almost complete absence of visible scanlines and motion artifacts.Of course,traditional Y/Pr/Pb component video,SCART,S-Video and composite video outputs are included for use with conven- tional televisions and projectors. Multiple Angle

25、: DVDs have the capability to show up to four different views of the same scene in a program.When a disc is encoded with multiple-angle information, pressing the Angle button will enable you to switch between these different views. Note that at present, few discs take advantage of this capability an

26、d, when they do, the multiple-angle technology may only be present for short periods of time within the disc. Producers will usually insert some sort of icon or graphic in the picture to alert you to the availabil- ity of multiple viewing angles. Reading:This is a message that you will see after you

27、ve loaded the disc and the tray has closed. It refers to the fact that the player must first examine the contents of the disc to see if it is a CD or DVD, and then extract the information about the type of material on the disc, such as languages, aspect ratios, subtitles, number of titles and more.T

28、he slight delay while the con- tents of the disc are read is normal. Resume:The operation of the Stop Button on the DVD works differently from what you are used to on CD players. On a traditional CD player, when you press the Stop button, the unit does just that: it stops playback. On a CD player, w

29、hen you press the start button again, the disc starts from the beginning.With the DVD, however, you have two options when playing DVD discs. Pressing Stop once will stop playback, but it actu- ally puts the unit in the Resume mode.This means that you can turn the machine off and, when you press play

30、 the next time, the disc will resume or continue from the point on the disc where the Stop button was pressed.This is help- ful if you are watching a movie and must inter- rupt your viewing session but wish to pick up where you left off. Pressing the Stop button twice will stop the machine in a trad

31、itional manner and, when the disc is played again, it will start from the beginning. In resume mode, the cover of the DVD will be displayed, if available. Otherwise, the Harman Kardon screen will appear. Terminology RadioFans.CN FEATURES Features High quality video Advanced sophisticated 10-bit MPEG

39、patible with the DVD. Similarly, although the DVD is capable of a wide range of features, not all discs include every capability of the DVD system. For example, although the DVD is compatible with multi-angle discs, that feature is only possible when the disc is specially encoded for multiple- angle

40、 play. In addition, the DVD is capable of playing back both Dolby Digital and DTS sound- tracks, but the number and types of tracks avail- able will vary from disc to disc.To make certain that a specific feature or soundtrack option is available, please check the options noted on the disc jacket.

41、Playback capability for CD-R, CD-RW,WMA, JPEG, MP3,VCD/SVCD, DVD-R, DVD+R, DVD- RW and DVD+RW discs may vary due to vari- ations in the quality of the disc and the recorder used to create the disc. Upgradeability via Internet The ”firmware” controlling the functionality of the Harman Kardon DVD is f

42、ully upgradeable. In the event of future improvements to its operations and features, it will be possible to download firmware upgrades from All you have to do is create a CD-R with the data and insert it in the DVD for an automatic upgrade.
