5.1 Music Disc
The DTS Music Disc (official name), DTS Audio CD or 5.1 Music Disc is an audio Compact Disc that contains music in one of various possible surround sound Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels).

The specification permits discrete channel configurations from 2.0 (L, R) to 6.1 (L, R, C, LFE, Ls, Rs, Cs), although 5.1 (L, R, C, LFE, Ls, Rs) is the most common. Physically, a DTS Music Disc conforms to the Red Book standard; however a DTS bitstream, based on the Coherent Acoustics compression algorithm, is actually encapsulated in each PCM audio track. This configuration permits any non-DTS enabled player to output multi-channel audio when connected to an external DTS-compliant processor (e.g. a typical AV receiver) via a digital interface like S/PDIF or HDMI, ...

Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as ''Compact Disc Digital Audio, Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 mebibyte, MiB of data. Capacity is routinely extended to 80 minutes and 700 mebibyte, MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; t ...

Surround Sound
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three ''screen channels'' of sound that played from three loudspeakers (left, center, and right) located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction (at ground level) around the listener. The technique enhances the perception of sound spatialization by exploiting sound localization: a listener's ability to identify the location or origin of a detected sound in direction and distance. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers. Surround sound typically has a listener location ( sweet sp ...

Red Book (CD Standard)
The Rainbow Books are a collection of CD format specifications. ''Red Book'' (1980) *CD-DA (''Digital Audio'') – standardized as IEC 60908 **CD-Text—a 1996 extension to CD-DA ** CD-MIDI—part of the original red-book standard **CD+G (''plus Graphics'') – karaoke *** CD+EG / CD+XG (''plus Extended Graphics'') – an extension of CD+G ''Yellow Book'' (1983) *CD-ROM (''Read-Only Memory'') – standardized as ISO/IEC 10149 in 1988 and ECMA-130 in 1989 **CD-ROM XA (''eXtended Architecture'') – a 1991 extension of CD-ROM ''Green Book'' (1986) *CD-i (''Interactive'') ''Orange Book'' (1990) Orange is a reference to the fact that red and yellow mix to orange. This correlates with the fact that CD-R and CD-RW are capable of audio ("Red") and data ("Yellow"); although other colors (other CD standards) that do not mix are capable of being burned onto the physical medium. ''Orange Book'' also introduced the standard for multisession writing. *CD-MO (''Magneto-Optical'') ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audiovisual Introductions In 1997
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance. Electrical wiring, Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, ...
