A signal to judge installation of DINB
1 DINB_EXIST O
H : DINB is installed.
Lock to the SDI signal, and a signal to show
whether the signal is a component SD
signal or not.
2 SDI_VALID O
H : Lock to a SDI signal, and signal format is valid.
L : SDI signal is invalid or there is no input.
Inputted video signal to SDI to show
3 SDI_NP O whether the signal is NTSC or PAL.
H : NTSC , L : PAL
Signal to show whether the audio signal
that is included in SDI signal is locked or
4 SDI_LOCK O not.
H : Locks to the embedded audio
L : Unlocks to the embedded audio
5 SDI_RST I DINB system reset signal input
A signal to show whether the error of
AES/EBU signal exists.
6 AES_ERROR O H : There is no error with AES/EBU signal.
L : There is an error with AES/EBU signal.
Set the operating mode of the AES/EBU
receiver.
7 MODE_SEL I
H : Clock output (master) mode
L : Clock input (slave) mode
