Is a digital coax cable the same as a SPDIF required on Phillips flatscreens for external audio (surround)?

Question

Philips tv hooking up to an LG surround sound reciever. The only output on the tv is SPDIF. Radio Shack was no help, nor was the Philips help line. I purchased a Digital coax, a optical to analog converter, and rca cable. Still no sound though when attempting to get tv audio through the surround. Surround only works when utilizing the functions of the reciver. IS THERE A DIFFERENCE BETWEEN SPDIF AND DIGITAL COAX?

Answer 1

Yes, that is the same as a Digital Coaxial Cable for audio. If the plug looks like an RCA connection then it should be the digital coaxial cable. If it is square looking, then you would need a Toslink Optical Audio cable.

Well, they both do the same thing, and do it equally well, but they are not the same cable.



Digital coax is just a high quality RCA cable. SPDIF, also called TOSLINK or Optical Digital Audio, uses a special cable made of a single strand of optics quality plastic to carry the audio signal as a beam of light.



Both are cables used to carry a surround sound signal although I've never heard of a converter for going from one to the other.



If your receiver has an input for digital coax, it should have at least one optical audio input as well.



The other issue, your TV may only send an audio signal from the optical audio port for certain types of inputs. For instance, my TV only does this if I'm using an antenna. It will not work for the other AV inputs. You'll have to check your TV's manual to find out. You may also need to turn off the TV's speakers in order to get anything to use the audio outputs on the TV at all.



Finally, remember that almost everything broadcast on TV/cable/satellite is only in stereo sound. So even if you get this working, for almost all programs, only your LG's front speakers and subwoofer will actually be emitting sound.

yes :) common use for the S/PDIF interface is to carry compressed digital audio as defined by the standard IEC 61937. This mode is used to connect the output of a DVD player to a home theater receiver that supports Dolby Digital or DTS surround sound. Another common use is to carry uncompressed digital audio from a CD player to a receiver. This specification also allows for the coupling of personal computer digital sound (if equipped) via optical or coax to Dolby or DTS capable receivers. SPDIF stands for Sony/Philips Digital Interface. It is a standard for digitally transferring audio. Digital transference, as opposed to analogue transmission, is immune to noise and according is the kind of transmission loved by audiophiles, musicians and professional people in the audio field that use computers as a tool. In many cases, however, the computer provides a SPDIF connection capability, unused due to unfamiliarity of user's or technician that assembled the computer.
