English 69TroubleshootingGlossaryDolby DigitalDigital multi-channel audio standard developed by DolbyLaboratories. It supports transmission and recording of high-quality digital audio signals from monaural up to 5.1 channelsusing an amount of data that is a fraction of the PCM audioformat. The main features of Dolby Digital include:• Downmixing optimized for monaural, stereo and Pro Logicconfigurations as well as for playback of 6.1-channel audio.• Transfer of information related to the dynamic range and theconversation level adjustment.• Wide range of operating bit rates.Dolby Digital EX/Dolby EXThese extensions of Dolby Digital add the surround back channelto the Dolby Digital channels to deliver a surround effect withenhanced presence and listener envelopment.Dolby Pro Logic IIThis is a matrix decoding technology developed by DolbyLaboratories. It generates 5-channel surround audio withrich feeling of presence from any stereo source, delivering anexcellent multidimensional sound field effect even from anordinary stereo music content including CD music. It offers threemodes including the Movie mode optimized for movie playback,the Music mode for music playback and the Game mode forgame play.Dolby Pro Logic IIxMatrix decoding technology developed by improving DolbyPro Logic II. It accepts any stereo or 5.1-channel audio inputand generates 7.1-channel surround audio with a more natural,smoother surround sound field. It also offers three modesoptimized for each source content, including the Movie modefor movie playback, the Music mode for music playback and theGame mode for game play.Dolby Digital PlusThis is an audio technology developed based on Dolby Digital byimproving both the sound quality and functions. It delivers multi-channel surround audio with completely discrete channels. Thecompatible bit rates have been expanded to between 32 kbpsand 6 Mbps from between 96 and 640 kbps with Dolby Digital.The excellent coding efficiency makes this technology capableof delivering quality audio in max. 7.1 channels withoutaffecting the bit rates assigned for the video and other services.Compatibility with existing home theater systems incorporatingthe Dolby Digital technology is also secured.Dolby True HDThis loss-less (reversible) audio technology has been developedby Dolby Laboratories and reproduces high-quality studio-mastered audio data perfectly with bit-order accuracy. It iscompatible with up to 7.1 channels when the sampling frequencyis 95 kHz and up to 5.1 channels when the sampling frequency is192 kHz.Dolby HeadphoneThis stereo audio technology has been developed by DolbyLaboratories and Lake DSP (presently Dolby Australia) andfeatures reproduction of surround audio through stereoheadphones.Dolby Virtual SpeakerThis is a speaker virtual technology that can generate an ideal 5.1-channel home theater environment using only a pair of speakers.DTS Digital SurroundDigital surround format developed by DTS Corporation. Itfeatures low compression rate and high sound quality, and iscapable of reproducing max. 5.1 channels.DTS-ESThis is a 6.1-channel audio technology developed by adding thesurround back channel to DTS Digital Surround.The signal of this format can also be played on existing DTS 5.1-channeel components. DTS-ES consists of two types, which areDTS ES Matrix and DTS-ES Discrete 6.1.DTS-ES MatrixWith this format, the audio for the surround back channel addedto the DTS 5.1-channel audio is allocated to the two surroundchannels during recording. When the signal is decoded, the audiofor the surround back channel is restored from the surroundchannels to deliver the 6.1-channel audio.DTS-ES DiscreteWith this format, the audio for the surround back channel addedto the DTS 5.1-channel audio is recorded in an independentchannel.DTS Neo:6This is a matrix decoding technology developed by DTSCorporation, capable of delivering max. 6.1 channels from any2-channel source. It includes two modes, including the DTS Neo 6CINEMA mode optimized for movie playback and the DTS Neo 6MUSIC mode optimized for music playback.DTS 96/245.1-channel digital audio format developed as an evolution of theDTS 5.1-channel format. It enables high-quality playback with 96kHz sampling frequency and 24-bit quantization (the signal ofthis format can also be reproduced on existing DTS 5.1-channelplayer components).
