APPENDIX ➤ Glossary En 68Audio/video informationSampling Frequency and Bit DepthThese 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 FrequencyThis defines the number of samples per second (sampling a finite set of discrete values in an analogsignal). The higher the sampling rate, the broader the range of frequencies that can be played back.• Bit DepthThis defines the amplitude value of sounds when quantifying analog signals as finite values. The higherthe bit depth, the deeper sounds are reproduced.Deep ColorThis is a video technology supported by the HDMI standard. It processes RGB or YCbCr signals at bitdepths of 10, 12, or 16 bits per color, whereas conventional formats utilize only 8-bit processing, enablingreproduction of more colors. Its gamut is comprised of a billion or more colors, while the gamuts ofconventional formats are comprised of only millions of colors or less. This broader gamut results in moreprecise reproduction of colors and greater detail in darker portions.Dolby DigitalThis is a compressed audio format for 5.1 channels. It was developed by Dolby Laboratories, and is widelyused with DVD discs.Dolby Pro Logic IIThis technology converts audio signal recorded in 2 channels to 5-channel signal.DTS Digital SurroundThis is a compressed audio format for 5.1 channels developed by DTS. It is widely used with DVD discs.FLACFLAC is a file format for lossless audio data compression. FLAC is inferior to lossy compressed audioformats in compression rate but provides higher audio quality.HDMIHigh-Definition Multimedia Interface (HDMI) is a digital audio/video interface that has become an industrystandard around the world. It is capable of transmitting both digital video and audio signals intact via asingle cable. It is also compliant with the High-bandwidth Digital Content Protection (HDCP) standard. Seehttp://www.hdmi.org for more information.MP3One of the compressed digital audio format used by MPEG. With psychoacoustic technologies, thiscompression method achieves a high compression rate. Reportedly, it is capable of compressing dataquantity by about 1/10 maintaining a certain level of audio quality.MPEG-4 AACAn MPEG-4 audio standard. It is used for mobile telephones, portable audio players, and audio streamingservices on Internet because it allows a high compression rate of data while maintaining better audio qualitythan MP3.Pulse Code Modulation (PCM)This technology records analog audio signals in digital form, converts analog audio signals to digital audiosignals, and transmits analog audio signals in digital form. It is the underlying technology for all digital audiosignal systems, and is widely used with CDs, Blu-ray Discs, and many other types of media as auncompressed audio format known as Linear PCM.WAVWindows standard audio file format, which defines the method of recording the digital data obtained byconverting audio signals. By default, the PCM method (no compression) is used, but you can also use othercompression methods.WMA (Windows Media Audio)One of the compressed digital audio formats developed by Microsoft Corporation. With psychoacoustictechnologies, this compression method achieves a high compression rate. Reportedly, it is capable ofcompressing data quantity by about 1/20 maintaining a certain level of audio quality.x.v.ColorThis is a color space supported by HDMI. It has become an international standard for video and offers abroader gamut than does the sRGB standard for expression of colors never before possible. It expands thecolor space while ensuring compatibility with the sRGB standard for more natural and vivid images.Network informationSSIDSSID (Service Set Identifier) is a name that identifies a particular wireless LAN access point.Wi-FiWi-Fi is a technology that allows an electronic device to exchange data or connect to the Internet wirelesslyusing radio waves. Wi-Fi offers the advantage of eliminating the complexity of making connections withnetwork cables by using wireless connection. Only products that complete Wi-Fi Alliance interoperabilitytests can carry the “Wi-Fi Certified” trademark.WPSWPS (Wi-Fi Protected Setup) is a standard established by the Wi-Fi Alliance, which allows easyestablishment of a wireless home network.Glossary
