What does SPDIF mean?

SPDIF means Sony/Philips Digital Interconnect Format

SPDIF is a default for passing a digital sound signal between different devices. You can compare it to a classic RCA plug, only SPDIF is digital (and fiber-based). The standard was developed in the years 80 by Sony and Philips as a transport standard for sound formats. The advent of the CD ensured that the desire arose to transmit as many signals as possible digitally. Almost all DVD players or AV receivers have an SPDIF connection. SPDIF supports uncompressed PCM signals and multichannel audio, 5.1 or 7.1 such as Dolby Digital and DTS. [YouTube] CUa4b1uv2cY [/youtube]
