 ==Overview==
-The term "<nowiki>S-PDIF</nowiki>" is an acronym for "Sony-Phillips Digital Interconnect Format" and is sometimes written as "[[SPDIF]]." The S-PDIF format was superseded by the IEC 60958 type II standard. It describes both the format of the encoding of the digital audio, clocking, and non-audio information, and the physical format (unbalanced 75 Ohm coaxial electrical or optical). The most common form of electrical connection is a coaxial 75 Ohm cable with "[[RCA]]" (or IEC or "Cinch") connectors. The most common [[optical]] connection is "[[Toslink]];" which was developed originally by Toshiba.

-Due to problems associated with unbalanced connections; the optical version of the S-PDIF interface was developed to eliminate ground-noise issues. Fiber optic technology has advanced since the S-PDIF standard was developed; so in many instances a significantly long optical interconnect can be used in place of a unbalanced coaxial connection.

-In order to address the need for a standardized connection to carry stereo linear PCM digital audio between pieces of equipment, SONY/Phillips adopted a version of the professional AES digital audio interface standard for consumer use. As technology progressed, the connection was adapted for alternative formats employing data compression for multi-channel audio formats for video (DTS and AC-3).
