4:3 Letter Box screen

This is one method for displaying a wide screen picture on a conventional sized (4:3) TV. While viewing a wide screen picture, the black bars appear on the top and the bottom of the screen.

DTS Digital Surround

Another discrete 5.1 channel digital audio format, available on CD, LD, and DVD software, developed by Digital Theater Systems, Inc. Compared to Dolby Digital, audio compression rate is relatively low. This fact allows DTS Digital Surround format to add breadth and depth to the reproduced sounds. As a result, DTS Digital Surround features natural, solid and clear sound.

To reproduce these surround signals, you need to connect an amplifier or a decoder compatible with DTS Digital Surround.

4:3 Pan-Scan screen

This is one method for displaying a wide screen picture on a conventional sized (4:3) TV. While viewing a wide screen picture, the left and right edges of the pictures will not be shown on the screen.

Dolby Digital

This is a digital audio compression technology that was developed by Dolby Laboratories. Dolby Digital encoding method (so-called discrete 5.1 channel digital audio format) records and compresses the left front channel, right front channel, center channel, left rear channel, right rear channel, and LFE channel (total 6 channels, but LFE channel is counted as 0.1 channel, therefore called 5.1 channels) signals digitally. Each channel is completely independent from other channel signals to avoid interference, therefore, you can obtain much better sound quality with stereo and surround effects. To reproduce these original surround signals, you need to connect an amplifier or a decoder compatible with Dolby Digital.

Linear PCM

This is a digital recording format that is used for audio CDs.

MPEG Multichannel

Digital audio compression format used for PAL/SECAM DVD software. (MPEG stands for “Moving Picture Experts Group” and has been originally developed for compressing video signals.) MPEG Multichannel is 5.1 channel surround using MPEG Audio coding format.

Playback Control (SVCD, VCD)

When a VCD has the PBC (Playback Control) function, you can enjoy menu-driven operations and high-resolution still pictures.

Sampling Frequency, Quantization Bits

When analog signals are converted into digital signals, they are divided into many points and digitized. This dividing method is called “sampling.” The sampling frequency indicates how many points one second is divided into – for example, for CD sound, one second is divided into 44100 points since its sampling frequency is

44.1kHz. On the other hand, the number of quantization bits indicates the volume size used to memorize each divided point. The larger this number is, the clearer the sound can be reproduced.

Titles and Chapters (DVD)

A DVD is divided into several titles (large divisions), and each title is divided into chapters (smaller divisions).

These divisions are assigned their particular numbers, so that they are easily accessed.

Tracks (SVCD, VCD, CD)

SVCD, VCDs and CDs are divided into tracks. Each track has its own number so that it is easily accessed.
