SPDIF stands for Sony/Philips Digital Interconnect Format.
This is an audio format used for
carrying digital audio signals on DVD players, CD players, computer sound cards and car
audio systems.
The format is also known as IEC 958 type II, S/P-DIF and S/PDIF.
Channel Data
Two 192 bit blocks (right and left channel data) are used.
These are segregated into a dozen
16 bit words.
The control codes are the initial six bits.
This audio format does not provide a
specific resolution or data rate.
The apparatus holding the connectors will establish the data
rate hand shake.
Bi-Phase Mark Code and Data Rates
The audio format uses the Bi-phase mark code.
This code can have one or two transitions per
bit.
This feature permits the first word clock to be pulled out of the base signal.
44.
1 kHz and
48 kHz are the most common rates used by the format.
48 kHz is (DAT- Digital Audio Tape)
data rate.
44.
1 kHz is for C
