Terminology & Abbreviations AC-3 The former name of the Dolby Digital audio-coding system . AC-3 followed AC-1

and AC-2. Still used in some standards documents. Angle In DVD-video, a specific view of a scene, usually recorded from a certain camera

angle. Different angles can be chosen while viewing the scene. CD Short for compact disc, an optical disc storage format developed by Philips and Sony. CD-DA Compact disc digital audio. The original music CD format, storing audio

information as digital PCM data. Defined by the Red Book standard. CD+G Compact disc plus graphics. A variation of CD which embeds graphical data in with

the audio data, allowing video pictures to be displayed periodically as music is played. Primarily used for karaoke.

CD-R An extension of the CD format allowing data to be recorded once on a disc by using dye-sublimation technology. Defined by the Orange Book standard.

Channel A part of an audio track. Typically there is one channel allocated for each loudspeaker.

Chapter In DVD-Video, a division of a title. Technically called a part of title (PTT). Closed Caption Text captions for video which are not normally visible, as opposed to open

captions, which are a permanent part of the picture. In the United States, the official NTSC Closed Caption standard requires that all TVs larger than 13 inches include circuitry to decode and display caption information stored on line 21 of the video signal. DVD-Video can provide closed caption data, but the subpicture format is preferred for its versatility.

Component Video A video system containing three separate color component signals, either red/green/blue (RGB) or chroma/color difference (YGbCr, YPbPr, YUV), in analog or digital form. The MPEG-2 encoding system used by DVD is based on color-difference component digital video. Very few televisions have component video inputs.

Composite Video An analog video signal in which the luma and chroma components are combined (by frequency multiplexing), along with sync and burst. Also called CVBS. Most televisions and VCRs have composite video connectors, which are usually colored yellow.

CD-i Compact disc interactive. An extension of the CD format designed around a set-top computer that connects to a TV to provide interactive home entertainment, including digital audio and video, video games, and software applications. Defined by the Green Book standard. CD-i Assn.

Terminology & Abbreviations

Dolby Digital A perceptual coding system for audio, developed by Dolby Laboratories and

accepted as an international standard. Dolby Digital is the most common means of encoding audio for DVD-Video and is the mandatory audio compression system for 525/60 (NTSC) discs.

Dolby Surround The standard for matrix encoding surround-sound channels in a stereo signal by applying a set of defined mathematical functions when combining center and surround channels with left and right channels. The center and surround channels can then be extracted by a decoder such as a Dolby Pro Logic circuit which applies the inverse of the mathematical functions. A Dolby Surround decoder extracts surround channels, while a Dolby Pro Logic decoder uses tially independent of the recording or transmission format. Both Dolby Digital and MPEG audio compression systems are compatible with Dolby Surround audio.

DTS Digital Theater Sound. A perceptual audio-coding system developed for theaters. A competitor to Dolby Digital and an optional audio track format for DVD-Video.

DVCD Stands for Double Video CD -- pretty popular format in mainland China. Format itself is nothing new really, its just a regular VideoCD overburned to include 90 to 99mins per CD, compared to regular 74mins per CD in standard VideoCD format.

DVD An acronym that officially stands for nothing, but is often expanded as Digital Video Disc or Digital Versatile Disc. The audio/video/data storage system based on 12-and 8-cm optical discs.

DVD+R DVD+Recordable defines a standard for recordable DVD drives and media defined by the DVDRW Alliance. Often called "plus R", the format is write once (compared to DVD+RW wich can be erased and rewritten). The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD Forum DVD-R specification. DVDRhelp DVDR information

JPEG Joint Photographic Experts Group. The international committee which created its namesake standard for compressing still images.

Karaoke Literally empty orchestra. The social sensation from Japan where sufficiently inebriated people embarrass themselves in public by singing along to a music track. Karaoke was largely responsible for the success of laserdisc in Japan, thus supporting it elsewhere.

Kodak Picture CD Kodak Picture CD is a CD that contains your pictures in JPEG format(.jpg) along with software that lets you view, enhance, share, and print your pictures from your computer. Some standalone DVD Players supports this format also, but then only for viewing. This format will also work on DVD Players that supports "JPEG file viewing" but you may lose some Kodak Picture CD specific features. Kodak Picture CD.

Macrovision An antitaping process that modifies a signal so that it appears unchanged on most televisions but is distorted and unwatchable when played back from a videotape recording. Macrovision takes advantage of characteristics of AGC circuits and burst decoder circuits in VCRs to interfere with the recording process.

MP3 MP3 is an acronym for MPEG-1 (or MPEG-2) Layer 3 audio encoding (it is not an

acronym for MPEG3). MP3 is a popular compression format used for audio files on computers and portable devices. The compression in MP3 works on the basis of a "psychoacoustic model" which means that parts of the audio that human ears cannot detect are discarded by the encoder. Although this is a LOSSY process, it can yield very high quality audio files are relatively high compression rates. A typical MP3 file encoded at 128 kbit/s (12:1 compression) is near CD quality. MP3 audio is increasingly being used in video production coupled with various MPEG-4 video codecs like divx. The audio may be encoded with a constant or variable bitrate.

Multiangle A DVD-Video program containing multiple angles allowing different views of a scene to selected during playback.

Multilanguage A DVD-Video program containing sound tracks and subtitle tracks for more than one language.

RGB Video information in the form of red, green, and blue tristimulus values. The combination of three values representing the intensity of each of the three colors can represent the entire range of visible light.

S/N Signal-to-noise ratio. Also called SNR. SACD Super Audio CD is the next generation of audio disc, offering full-range,

uncompressed digital multi-channel surround sound. SACD can also be backward compatible using so called hybrid discs with an extra layer that allows them to be played on conventional CD players but then only with ordinary CD quality. SACD can be played on SACD Players, DVD Players with SACD support and if using hybrid discs also CD Players. SACD is currently competing with DVD-Audio as the new audio defacto standard. Philips SACD information.

Subtitle A textual representation of the spoken audio in a video program. Subtitles are often used with foreign languages and do not serve the same purpose as captions for the hearing impaired.

SVCD SVCD stands for 'Super VideoCD'. A SVCD is very similiar to a VCD, it has the capacity to hold about 35-60 minutes on 74/80 min CDs of very good quality full-motion MPEG-2 video along with up to 2 stereo audio tracks and also 4 selectable subtitles. A SVCD can be played on many standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder / player. SVCDHelp.com.

S-video A video interface standard that carries separate luma and chroma signals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of s-video is significantly better than composite video since it does not require a comb filter to separate the signals, but it’s not quite as good as component video. Most high-end televisions have s-video inputs. S-video is often erroneously called S-VHS.

System menu The main menu of a DVD-Video disc, from which titles are selected. Also called the title selection menu or disc menu

3


Title The largest unit of a DVD-Video disc (other than the entire volume or side). Usually

a movie, TV program, music album, or so on. A disc can hold up to 99 titles, which can be selected from the disc menu.

VCD VCD stands for 'Video Compact Disc' and basically it is a CD that contains moving pictures and sound. If you're familiar with regular audio/music CDs, then you will know what a VCD looks like. A VCD has the capacity to hold up to 74/80 minutes on 650MB/700MB CDs respectively of full-motion video along with quality stereo sound. VCDs use an encoding standard called MPEG-1 to store the video and audio. A VCD can be played on almost all standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder / player. VCDHelp.com.

YUV In the general sense, any form of color-difference video signal containing one luma and two chroma components. Technically, YUV is applicable only to the process of encoding component video into composite video.

WMF Windows Media Format files are audio/video files encoded with the Windows Media Encoder, providing high quality and media security for streaming and download-and-play applications on PCs, set-top boxes, and portable devices. Windows Media Format comprises Windows Media Audio and Video codecs, an optional integrated digital rights management (DRM) system, and a file container. Microsoft WMF Information CVD China Video Disk - a precursor to SVCD marketed since 1998. Resolutions are 352x480 NTSC, 352x576 PAL, 44.1khz audio (unlike 1/2 D1 DVD that is the same resolution at 48khz audio). Not all players will play CVD (compatible players). CVD Guide DivX DivX™ is a new format for digital video, much like MP3 is a format for digital music. DivX™ is the brand name of a patent-pending video compression technology created by DivXNetworks, Inc., (also known as Project Mayo). The DivX™ codec is based on the MPEG-4 compression standard. This codec is so advanced that it can reduce an MPEG-2 video (the same format used for DVD or Pay-Per-View) to ten percent of its original size. DivX.com. DVD+RW DVD+RW is a ReWriteable media format of the DVD+R standard. DVD-Audio DVD-Audio or sometimes called DVD-A is a separate format from DVD-Video. It is a format specifically designed to provide the highest possible audio fidelity capable on DVD. DVD-Audio provides for audio in stereo and in multi-channel surround in a wide range of specifications. In addition to audio, a DVD-Audio disk can contain a limited amount of video, which can be used to display text, such as lyrics or notes. DVD-Audio can only be played on DVD Players with DVD-Audio support (most DVD Players do not support this format). DVD-Audio is currently competing with SACD as the new audio defacto standard. DigitalAudioGuide DVD Audio FAQ DVD-R DVD-Recordable defines a standard for recordable DVD drives and media defined by the DVD Forum. Often called "minus R", the format is write once (compared to DVD-RW wich can be erased and rewritten). The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD+R format. DVDRhelp DVDR information

DVD-RAM A recordable format supported by the DVD Forum. It has superior recording features but it is not compatible with most DVD-ROM drives or DVD Video players. It works well when set up like a removable hard disk. DVD-RW DVD-RW is a ReWriteable media format of the DVD-R standard. DVD-Video DVD-Video is the video element of the DVD format. DVD Demystified DVD-Video Features. DVD±R A term used to cover both the DVD-R and DVD+R standards in one word.

HDCD High Definition Compatible Digital® (HDCD®) is a patented encode/decode

process for delivering the full richness and detail of the original microphone feed on Compact Discs and DVD-Audio. HDCD has been used in the recording of more than 5,000 CD titles, which include more than 250 Billboard Top 200 recordings and more than 175 GRAMMY® nominations, and account for more than 300 million CDs sold. HDCD-encoded CDs sound better because they are encoded with 20 bits of real musical information, as compared with 16 bits for all other CDs. HDCD overcomes the limitation of the 16-bit CD format by using a sophisticated system to encode the additional 4 bits onto the CD while remaining completely compatible with the existing CD format. HDCD provides more dynamic range, a more focused 3-D soundstage, and extremely natural vocal and musical timbre. With HDCD, you get the body, depth, and emotion of the original performance not a flat, digital imitation.

Repair of Power Board

Repair of Power Board I. Power switch working principles

The internal parts of main power switch IC DH321 (IC1) consist of: oscillation circuit, error test and T-ratio over current overheating protection, under-voltage and over voltage protection, and power-amp MOSFET. For descriptions of pins and block diagrams of internal IC, see appendix. 1. Conversion from AC. to DC. circuit

240V/110V AC. current flows restrictively through C1,fuse and L1 combines to be share-mode and differential-mode filter circuit, filtering external disturbance and preventing internal electromagnetic radiation, and through D1~D4 to combine as bridge rectification. After C3 undergoes electrolytic filter, we can obtain a 320/140V DC. voltage (Uhv).

2. Process to start up the software Connect R6, D6 ,C6 and bias winding to the multi-functional VCC pin of IC1, test

DC. input voltage Uhv. This can effect as a protective function to restrict under-voltage current and reduce over voltage T-ratio.

R3,R4,R5 is the charging circuits to start up software, and electric current inside IC1 flows from control pin 5. When Vc reaches 12V, internal oscillation circuit initiates, motivating power-amp MOSFET, forming AC. current on T1 primary winding, coupling to secondary winding. Power switch start-up has completed.

3. Bias winding After starting the power, T1 bias winding supplies bias current and error current to

pin2 of IC1, through D6,R6 and C6 rectifier filter . 4. Clamping protective circuit C4, R2, D5 are connected to primary switch transformer, in order to fix the leakage

electrode voltage of IC1 and to prevent the voltage exceeding the limit of IC1 leakage electrode voltage when switch transformer discharges at startup or overloading stage.

5. Regulation process of output voltage When the input current of control pin (FB) IC1 decreases (or increases), oscillation

waveform will be regulated automatically so that T ratio will increase (or decrease) and the output voltage will increase (or decrease).

Output voltage feedback circuit is completed by IC2, IC3. IC3 (TL431) is a reference regulation IC, reference voltage is 2.5V: Its pins are shown on the diagram below:

19


Main characteristics of TL431

(1) Anode voltage Vka, anode change in voltage (2) reference voltage, reference change in voltage

Secondary main winding, set 5V to output change in voltage△Vo; we can deduce △VR7=356△Vo

From this formula we can deduce: If 5V Voltage rises, the voltage VR7 of the two ends of R7 will rise, error voltage increases by 356 times. VR7 error voltage is added to the light-emitting diode of IC3 optical coupling, so that the emitting intensity increases. Coupling increases the current of IC3 light-electric triode. The control current of IC2 then rises and the T ratio of open/close power reduces, thus reducing 5V output voltage.

On the other hand, if 5V voltage reduces, negative feedback will cause it to rise automatically. 6. Output voltage for the first time After 5V main feedback winding has been regulated, other windings will be

regulated relatively, and the voltage required by each circuit of the DVD machine can be obtained.
