<P> S / PDIF (Sony / Philips Digital Interface) is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances . The signal is transmitted over either a coaxial cable with RCA connectors or a fibre optic cable with TOSLINK connectors . S / PDIF interconnects components in home theatres and other digital high - fidelity systems . </P> <P> S / PDIF is based on the AES3 interconnect standard . S / PDIF can carry two channels of uncompressed PCM audio or compressed 5.1 / 7.1 surround sound (such as DTS audio codec); it cannot support lossless surround formats that require greater bandwidth . </P>
