SDigital audio output connector (Optical)

HThe digital audio output connector (optical) converts

72electrical signals into optical signals and transfers them to the amplifier. Consequently, it has a number of features including its immunity from electrical inter- ference from external sources and its ability to prevent the generation of noise and its minimal effect on the external environment. This function is provided only with CQ-VD7500U

Dolby Digital

This fully discrete format divides the music signals into 5.1 channels: Front Left (L), Front Right (R), Center (C), Left Surround (LS), Right Surround (RS) and Subwoofer (SW: 0.1 channel) for recording and playback. The number of channels that are recorded depends on the software (1 to 5.1 channels).

Dolby Digital 5.1

Dolby Digital 5.1 is a method of transmitting and stor- ing 5.1-channel soundtracks via newer digital media such as DVD, digital cable, digital broadcast TV (DTV), and satellite transmissions. Unlike the Dolby Surround encode/Pro Logic decode process, which sacrifices channel separation to get surround onto any stereo soundtrack, Dolby Digital 5.1 is a discrete system that keeps the multiple channels fully separated through- out the encoding and decoding processes. In addition to having full-range Left (L), Center (C), Right (R), Left Surround (LR), and Right Surround (RS) channels, Dolby Digital 5.1 soundtracks carry a sixth (“.1”) channel (Subwoofer) recorded with low-frequency effects (those bass rumbles and booms you feel as well as hear in a well-equipped cinema).

Dolby Pro Logic

This format records signals from four channels [Front Left (L), Front Right (R), Center (C), and Monaural Surround (S)] in two channels, decodes those chan- nels through a Dolby Pro Logic decoder, and then out- puts the resulting signals in four channels.

Dolby Pro Logic II

Dolby Pro Logic II is an advanced matrix decoder that derives five-channel surround (Left, Center, Right, Left Surround, and Right Surround) from any stereo pro- gram material, whether or not it has been specifically

CQ-VD7700U/VD7500U

Dolby Surround encoded. On encoded material such as movie soundtracks, the sound is more like Dolby Digital 5.1 (see above), while on unencoded stereo material such as music CDs the effect is a wider, more involving soundfield. Among other improvements over Pro Logic, Pro Logic II provides two full-range sur- round channels, as opposed to Pro Logic’s single, lim- ited-bandwidth surround channel.

dts

This format requires more data than Dolby Digital, and provides higher quality surround playback.

Similar to Dolby Digital, this fully discrete format divides the music signals into 5.1 channels: Front Left (L), Front Right (R), Center (C), Left Surround (LS), Right Surround (RS) and Subwoofer (SW: 0.1 chan- nel) for recording and playback.

G.726

G.726 is a sound data standard of compression/expansion recommended by CCITT (Consultative Committee for International Telephony and Telegraphy). Applying this standard, the PCM (Pulse Code Modulation) sound data can be compressed or expanded effectively.

The applied software is mainly used for digital telephones, digital voice recorders, digital camcorders and so on.

Interactive DVD

An interactive DVD is DVD software which includes multiple angles, multiple plot endings, etc.

Letterbox screen

This refers to a screen on which the playback picture of wide-screen DVDs or Video CDs appears with black bands running along the top and bottom.

Pan & Scan screen

This refers to a screen on which the playback picture of wide-screen DVDs or Video CDs is cut off at the left and right sides.

LPCM (Linear PCM audio)

In this format, the audio signal is converted to digital data and recorded in two channels without compres- sion. Because the capacity of a DVD video disc is large, it can store more data with better accuracy than a CD.

MPEG4 (ASF) is an audio/video format for the online streaming proposed by Microsoft Corporation. This format allows you to treat audio/video data easily on your personal computer.

Generally, ASF files are so light that they can be stored on comparatively small-capacity media such as SD memory card because they are made for online streaming.

Playback control (Video CD)

If the Video CD has “With Playback Control” or some- thing similar written on the disc surface or on the jacket, the scenes or information to be viewed (or lis- tened to) can be selected interactively by using the menu shown on the screen.

In these instructions, playback using the menu screen is referred to as “menu play” for video CDs. This play- er supports Video CDs with playback control.

Title, Chapter (DVD)

DVDs are divided into large sections (titles) and/or small sections (chapters). Each section is numbered; these numbers are called “Title number” or “Chapter number”.

	Title 1		Title 2

Chapter 1	Chapter 2	……	Chapter 1	……

Track (Video CD/CD)

Video CDs or CDs are divided into some sections (tracks). Each section is numbered; these numbers are called “Track number”.

Track 1

Track 2

Track 3
