Terminology & Abbreviations

C-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.

A/V Audio/Video

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.

ATAPI Advanced Technology Attachment (ATA) Packet Interface. An interface between a

computer and its internal peripherals such as DVD-ROM drives. ATAPI provides the

command set for controlling devices connected via an IDE interface. ATAPI is part of

the Enhanced IDE (E-IDE) interface, also known as ATA-2. ATAPI was extended for use

in DVD-ROM drives by the SFF 8090 specification.

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 sub picture 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 (YCbCr, 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.

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 tally 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.DV Digital Video. A camcorder format for high-quality video, different from PEG. It is

converted into MPEG 2 Video when recorded on DVD+RW

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+RThese discs can only be written to once. Existing recordings can be hidden but not

deleted. So, any disc space already used by a recording cannot be regained. DVD+R

discs are required to be "Finalized" before they will be compatible with standard DVD

Players. Once a disc is finalized, no further recordings can be made.

DVD+RW Discs can be written to and erased multiple times. Existing recordings can be deleted

and disc space regained. These discs do not require a finalization procedure. As soon as

a recording is made, the disc will be compatible with standard DVD Players.

EasyLinkIf your TV set and your video recorder are equipped with this feature, they can

exchange information to adjust certain settings to each other, such as the TV channel

order and other user preferences

digital signals, as used by Digital Video camcorders.

Index Picture Screen A screen that gives an overview of a DVD+RW disc, with

indexpictures that each represent a recording.

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.

Macro vision An ant taping process that modifies a signal so that it appears unchanged on

most televisions but is distorted and unmatchable when played back from a videotape

recording. Macro vision takes advantage of characteristics of AGC circuits and burst

decoder circuits in VCRs to interfere with the recording process.MPEG Motion Picture Experts Group. A collection of compression systems for digital audio and

video.

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.

hearing impaired.

SECAM See TV system.

ShowView See VideoPlus+. ShowView is a trademark of Gemstar Development Group.

S-video A video interface standard that carries separate luma and chrome 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 its 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.

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.

7-1 Repair of Power Board

I. Power switch working principles

The internal parts of main power switch IC 2A365 (IC2) consist of: oscillation circuit,

error test and T-ratio over current overheating protection, under-voltage and over voltageprotection, and power-amp MOSFET. For descriptions of pins and block diagrams of internal

IC, see appendix.

1. Conversion from AC. to DC. circuit

230V/110V AC. current flows restrictively through F1 fuse, L1 and C1,C6,C7

combines to be share-mode and differential-mode filter circuit, filtering external

disturbance and preventing internal electromagnetic radiation, and through

D1~D2 and D5~D6 to combine as bridge rectification. After C2 undergoes

electrolytic filter, we can obtain a 320/140V DC. voltage (Uhv).

2. Process to start up the software

Connect R3, R8 to the multi-functional VCC pin of IC2, test DC. input voltage Uhv.

This can effect as a protective function to restrict under-voltage current and reduce over

voltage T-ratio.

C44 and C24 are the charging circuits to start up software, and electric current

inside IC flows from control pin 1. When Vc reaches 5.3V, internal oscillation circuit

initiates, motivating power-amp MOSFET, forming AC. current on T1 P1~P3 primary

winding, coupling to secondary winding. Power switch start-up has completed.

3. Bias winding

After starting the power, T1 P5~P6 bias winding supplies bias current and errorcurrent to pin7l of IC2, through D10 and C13 rectifier filter .

4. Clamping protective circuit

C3, R2, D8 are connected to primary switch transformer, in order to fix the leakage

electrode voltage of IC2 and to prevent the voltage exceeding the limit of IC2 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) IC2 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 Q5, U3.

Q5 (TL431) is a reference regulation IC, reference voltage is 2.5V:

Its pins are shown on the diagram below:

From this formula we can deduce: If 5V Voltage rises, the voltage VR25 of the

two ends of R25 will rise, error voltage increases by 356 times. VR25 error

voltage is added to the light-emitting diode of U3 optical coupling, so that the

emitting intensity increases. Coupling increases the current of U3 light-electric

triode. The control current of IC2 then rises and the T ratio of open/close power

reduces, thus reducing 5V output voltage.
