Description
①
COAX digital audio output
Outputs audio to the selected Port when HDMI 1 or 2 ARC signal is received.
②
HDMI 1
This is HDMI digital video/audio output terminal 1. (Supports HDCP)
③
HDMI 2
This is HDMI digital video/audio output terminal 2. (Supports HDCP)
④
Standby LED
Lights when output preparation is complete.
On: Normal
Off: Error (module damaged, wrong slot, etc.)
● When data transfer speed (TMDS clock) output is 3G or below, Timing edited in Timing editing can be output, however,
Timing output that exceeds 3G will be output from CEA-861-F standard Video Identification Code (VIC) 93 to107 Timing
only.
(Output of edited Timing that exceeds 3G is not available.)
Additionally, VIC91 and VIC92 Timing output is not available.
VIC91 : 2560x1080p Field Rate100Hz Pixel Frequency 371.25 MHz
VIC92 : 2560x1080p Field Rate119.88/120 Hz Pixel Frequency 495 MHz
● Deep Color output for Timing that exceeds 3G uses 8-bit display gradation for output color format YCbCr 4:2:0, and 12-bit
display gradation for RGB and YCbCr4:4:4 16bit. (Low-level bits are output with 0 fill-in for Deep Color.)
● 3D display for Timing that exceeds 3G is only compatible with Top and Bottom and Side By Side (Half).
(TMDS clock calculation method)
Output color format coefficient
RGB=1.0, YCbCr4:4:4=1.0, YCbCr4:2:2=0.666(2/3) ,YCbCr4:2:0=0.5(1/2)
Output bit coefficient
8 bits = 1.0, 10 bits = 1.25, 12 bits = 1.5, 16 bits = 2.0
TMDS clock = dot clock x output color format coefficient x output bit coefficient
Ex. Dot clock: 148.5 MHz (1.485G)
Output color format: YCbCr4:2:2 (output color format coefficient 0.666(2/3))
Output bit coefficient: 10 bits (output bit coefficient 1.25)
TMDS clock = 1.485G x 0.666 (2/3) x 1.25
TMDS clock = 1.2375G
