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 bu rst. Also called CVBS. Most televisions and VCRs have composite video connectors, which are usually co lored 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

SAFETY PRECAUTIONS
IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the factory, the products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following pre­cautions when a set is being serviced.
·Precautions during Servicing
1. Locations requiring special caution are denoted by labels and inscriptions on the
rear panel and certain parts of the product. When performing service, be sure to read and comply with these and other cautionary notices appearing in the operation and service manuals .
2. Parts identified by the symbol in schematic diagram parts are critical for safety.
Replace only with specified part numbers. Note : Parts in this category also include those specified to comply with laser
emission standards for Products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation.
3. Use Specified internal wiring. Note especially:
1) Double insulated wires
2) High voltage leads

SAFETY PRECAUTIONS
6.Check that replaced wires do not contact sharp edged or pointed parts.
7. 1) When a power cord has been replaced, check that A mark is made on the cord,
under strain, near the aperture, and the flexible cord is subjected 100times to a pull of 40N for a duration of 1 second each.
2) During the test, the cord shall not be displaced by more than 2mm
8.Also check areas surrounding repaired locations.

10. After updated the hazardous live part or accessible part, if the clearance or creep age distance can’t accord with the safe request, then need adopt reinforced insulation method for ensure safety.
SAFETY CHECK AFTER SERVICING
Examine the area surrounding the repaired location for damage or deterioration.
2-2
SAFETY PRECAUTIONS
Observe that screws, parts and wires have been returned to original positions. Afterwards, perform the following tests and confirm the specified values in order to verify compliance with safety standards.
·Insulation resistance test
Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) See table below.
·Dielectric strength test Confirm specified dielectric strength or greater between power cord prongs and exposed accessible parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) See table below.
·Clearance distance When replacing primary circuit components, confirm specified clearance distance (d), between soldered terminals, and between terminals and surrounding metallic parts .See table below.
