Composite (CVBS) - Low quality analogue video

signal format. Can carry PAL signal..

Component (YPbPr) - Higher quality analogue

video signal format. Splits the video signal into

three components to maintain signal clarity and

capable of carrying high definition video up to

1080p. Component is rapidly being phased out in

favour of digital video via HDMI.

HDMI: High Definition Multimedia Interface. A

specification developed by the HDMI Working

Group that combines multi-channel audio and

high definition video and that controls signals into

a single digital interface for use with DVD players,

digital television, and other audiovisual devices.

Aspect ratio: The ratio of vertical and horizontal

sizes of a displayed image. The horizontal vs.

vertical ratio of conventional TVs is 4:3, and that of

widescreens is 16:9.

Disc menu: A screen display prepared for allowing

selection of images, sounds, subtitles, multi-angles,

etc recorded on a DVD.

JPEG: A very common digital still picture format. A

still-picture data compression system proposed

by the Joint Photographic Expert Group, which

features small decrease in image quality in spite of

its high compression ratio.

XviD: MPEG-4 based video compression technology,

that can shrink digital video to sizes small enough

to be transported over the internet, while

maintaining high visual quality.

Container. The multimedia container file is used

to identify and interleave different data types.

Simpler container formats can contain different

types of audio codecs, while more advanced

container formats can support multiple audio and

video streams, subtitles, chapter-information, and

meta-data (tags) — along with the synchronization

information needed to play back the various

streams together. There are many container

formats, such as AVI, Matroska (MKV), MOV, MP4,

OGM, WAV, etc.

Analog: Sound that has not been turned into

numbers. Analog sound varies, while digital sound

has specific numerical values. These jacks send

audio through two channels, the left and right.

Digital: Sound that has been converted into

numerical values. Digital sound is available when

you use the DIGITAL AUDIO OUT COAXIAL or

OPTICAL jacks. These jacks send audio through

multiple channels, instead of just two channels as

analog does.

PCM (Pulse Code Modulation): A system for

converting analog sound signal to digital signal for

later processing, with no data compression used in

conversion.

S/PDIF - Format for carrying audio digitally over

either optical (TOSLINK) or electrical (Coaxial) cable.

Can carry high quality DTS or Dolby Digital audio.

TOSLINK - Standardised optical fibre connection

system invented by Toshiba. Typically used to

connect the Player to a AV receiver for pass-through

of HiFi audio. When we refer to digital optical we

mean S/PDIF via TOSLINK.

Dolby Digital (or AC-3) - It isa surround sound

system developed by Dolby Laboratories

containing up to six channels of digital audio (front

left and right, surround left and right, center and

subwoofer). It is a required standard of both Blu-

Ray and DVD and the most widely supported. It

is a ‘lossy’ format so is of a lesser quality than the

studio original. Surround sound up to 5.1 channel is

supported. The Dolby Digital audio track can either

be decoded (downmixed) to stereo in the Player

or digitally bitstreamed direct (passthrough) to a

compatible AV receiver (via TOSLINK/Coaxial/HDMI)

for decoding.

DTS (Digital Theater System) - is a required

standard of both Blu-Ray and DVD players and is

widely regarded to produce audio quality superior

to Dolby Digital. Up to 5.1 channel surround sound

is supported. DTS is a ‘lossy’ compression standard

so the audio is of a lesser quality than the original

studio recording. The DTS audio track can either

be decoded (downmixed) in the Player to stereo

or digitally bitstreamed direct (passthrough) to a

compatible receiver (via TOSLINK/Coaxial/HDMI) for

decoding.

Bit Rate: The amount of data used to hold a given

length of music; measured in kilobits per seconds,

or kbps. Or, the speed at which you record.

Generally, the higher the bit rate, or the higher

the recording speed, the better the sound quality.

However, higher bit rates use more space on a Disc.

Title: The longest section of a picture or music

feature on DVD, music, etc., in video software, or

the entire album in audio software. Each title is

assigned a title number enabling you to locate the

title you want.

Chapter: Sections of a picture or a music piece on a

DVD that are smaller than titles. A title is composed

of several chapters. Each chapter is assigned a

chapter number enabling you to locate the chapter

you want.

Parental Control: A function of the DVD to limit

playback of the disc by the age of the users

according to the limitation level in each country.

The limitation varies from disc to disc; when it

is activated, playback will be prohibited if the

software’s level is higher than the user-set level.

Surround: A system for creating realistic

threedimensional sound fields full of realism by

arranging multiple speakers around the listener.
