Glossary Sampling Frequency and Bit Depth These are values that represent the amount of information used to convert analog signals to digital signals. They may be expressed as 48kHz/24bit, for example. • Sampling Frequency This defines the number of samples per second (sampling a finite set of discrete values in an analog signal). The higher the sampling rate, the broader the range of frequencies that can be played back. • Bit Depth This defines the amplitude value of sounds when quantifying analog signals as finite values. The higher the bit depth, the deeper sounds are reproduced. Deep Color This is a video technology supported by the HDMI standard. It processes RGB or YCbCr signals at bit depths of 10, 12, or 16 bits per color, whereas conventional formats utilize only 8-bit processing, enabling reproduction of more colors. Its gamut is comprised of a billion or more colors, while the gamuts of conventional formats are comprised of only millions of colors or less. This broader gamut results in more precise reproduction of colors and greater detail in darker portions. Dolby Atmos Dolby Atmos is an object-based surround sound technology developed by Dolby Laboratories. Traditional surround sound technologies record and control audio for each channel. Dolby Atmos records audio content as a collection of many objects (a combination of audio information and information related to movement of sound positions) and precisely controls content in accordance with various home theater environments for an acoustic environment more realistic and three-dimensional than ever before. Another advantage is the ability to record sounds coming from overhead. It was originally developed for movie theaters, but can also be applied to home devices. Dolby Atmos content is provided in the Dolby True HD format, including Dolby Atmos streams, or in the Dolby Digital Plus format. Dolby Digital This is a compressed audio format for 5.1 channels. It was developed by Dolby Laboratories, and is widely used with DVD discs. Dolby Digital EX This technology enables 6.1-channel playback for sources encoded in the Dolby Digital EX format. It takes the Dolby Digital 5.1-channel setup one step further with an additional back surround channel. Dolby Digital Plus This is a compressed audio format for 7.1 channels developed by Dolby Laboratories. It is fully compatible with Dolby Digital and is available for playback on Dolby Digital-enabled audio systems. It is widely used with Blu-ray Discs. Dolby Surround This surround sound technology was developed by Dolby Laboratories to extend 2- to 7.1-channel content in accordance with audio systems used for playback. It not only enables playback of Dolby Atmos content but also extends traditional audio content to surround sound, including height channel audio, for 3D surround sound playback. Dolby TrueHD This advanced lossless audio technology was developed by Dolby Laboratories for high-definition disc-based media to deliver sounds that are identical, bit for bit, to studio masters for a great home theater experience. It delivers up to 8 discrete channels of 24-bit/96-kHz (up to 6 discrete channels of 24-bit/192 kHz) audio simultaneously, and is widely used with Blu-ray Discs. DTS Digital Surround This is a compressed audio format for 5.1 channels developed by DTS. It is widely used with DVD discs. DTS Express This is a compressed audio format for 5.1 channels. It provides a higher compression ratio than the DTS Digital Surround audio format, and was developed specifically for network streaming and Blu-ray Disc secondary audio. DTS-HD High Resolution Audio This is a compressed audio format for 24-bit/96-kHz superior sound quality with 7.1 channels developed by DTS. It is fully compatible with DTS Digital Surround, and is widely used with Blu-ray Discs. DTS-HD Master Audio This advanced lossless audio technology was developed by DTS for high-definition disc-based media to deliver sounds identical, bit for bit, to studio masters for a great home theater experience. It delivers up to 8 discrete channels at 24-bit/96 kHz (up to 6 discrete channels at 24-bit/192 kHz) audio simultaneously, and is widely used with Blu-ray Discs. DTS Neo:6 This technology enables discrete 6-channel playback from 2-channel sources. There are two modes available: "Music mode" for music sources and "Cinema mode" for movie sources. It provides a channel split effect similar to sources recorded as discrete surround sound. APPENDIX ➤ Glossary En 103
