Consequently, it has a numberof features including its immunity from electrical inter-ference from external sources and its ability to preventthe generation of noise and its minimal effect on theexternal environment. This function is provided onlywith CQ-VD7500UDolby DigitalThis fully discrete format divides the music signalsinto 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 andplayback. The number of channels that are recordeddepends on the software (1 to 5.1 channels).Dolby Digital 5.1Dolby Digital 5.1 is a method of transmitting and stor-ing 5.1-channel soundtracks via newer digital mediasuch as DVD, digital cable, digital broadcast TV (DTV),and satellite transmissions. Unlike the Dolby Surroundencode/Pro Logic decode process, which sacrificeschannel separation to get surround onto any stereosoundtrack, Dolby Digital 5.1 is a discrete system thatkeeps the multiple channels fully separated through-out the encoding and decoding processes. In additionto having full-range Left (L), Center (C), Right (R), LeftSurround (LR), and Right Surround (RS) channels,Dolby Digital 5.1 soundtracks carry a sixth (“.1”)channel (Subwoofer) recorded with low-frequencyeffects (those bass rumbles and booms you feel aswell as hear in a well-equipped cinema).Dolby Pro LogicThis format records signals from four channels [FrontLeft (L), Front Right (R), Center (C), and MonauralSurround (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 IIDolby Pro Logic II is an advanced matrix decoder thatderives five-channel surround (Left, Center, Right, LeftSurround, and Right Surround) from any stereo pro-gram material, whether or not it has been specificallyDolby Surround encoded. On encoded material suchas movie soundtracks, the sound is more like DolbyDigital 5.1 (see above), while on unencoded stereomaterial such as music CDs the effect is a wider, moreinvolving soundfield. Among other improvements overPro Logic, Pro Logic II provides two full-range sur-round channels, as opposed to Pro Logic’s single, lim-ited-bandwidth surround channel.dtsThis format requires more data than Dolby Digital, andprovides higher quality surround playback.Similar to Dolby Digital, this fully discrete formatdivides 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.726G.726 is a sound data standard of compression/expansionrecommended by CCITT (Consultative Committee forInternational Telephony and Telegraphy). Applying thisstandard, the PCM (Pulse Code Modulation) sound datacan be compressed or expanded effectively.The applied software is mainly used for digital telephones,digital voice recorders, digital camcorders and so on.Interactive DVDAn interactive DVD is DVD software which includesmultiple angles, multiple plot endings, etc.Letterbox screenThis refers to a screen on which the playback pictureof wide-screen DVDs or Video CDs appears with blackbands running along the top and bottom.Pan & Scan screenThis refers to a screen on which the playback pictureof wide-screen DVDs or Video CDs is cut off at the leftand right sides.Manufactured under license from DolbyLaboratories. “Dolby” and the double-D symbolare trademarks of Dolby Laboratories.Manufactured under license from DolbyLaboratories. “Dolby”, “Pro Logic”, and thedouble-D symbol are trademarks of DolbyLaboratories.LPCM (Linear PCM audio)In this format, the audio signal is converted to digitaldata and recorded in two channels without compres-sion. Because the capacity of a DVD video disc islarge, it can store more data with better accuracy thana CD.MPEG4MPEG4 (ASF) is an audio/video format for the onlinestreaming proposed by Microsoft Corporation. This formatallows you to treat audio/video data easily on your personalcomputer.Generally, ASF files are so light that they can be stored oncomparatively small-capacity media such as SD memorycard 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 thejacket, the scenes or information to be viewed (or lis-tened to) can be selected interactively by using themenu shown on the screen.In these instructions, playback using the menu screenis 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/orsmall sections (chapters). Each section is numbered;these numbers are called “Title number” or “Chapternumber”.Track (Video CD/CD)Video CDs or CDs are divided into some sections(tracks). Each section is numbered; these numbers arecalled “Track number”.Chapter 1 Chapter 2 …… Chapter 1 ……Title 1 Title 2“DTS” and “DTS Digital Surround” are registeredtrademarks of Digital Theater Systems, Inc.“DTS” and “DTS 2.0” are trademarks of DigitalTheater Systems, Inc.Track 1 Track 3Track 2 ……TrackThis product incorporates copyright protection technology that is protected by U.S. patents and other intellectualproperty rights.
