Parameter
device: Model
“1” (fixed).
ch: Channel
1 to 512 = Channel 1 to Channel 512
If a command is input from the RS-232C connector of NJR-T01SDI or from IP-NINJAR
Configurator through LAN, the value is “1” (fixed).
reserved: Reservation
“1” (fixed).
act_h: The number of horizontal active pixels
act_v: The number of vertical active pixels
scan_type: Scanning method
-6 = No signal, 0 = Progressive, 1 = Interlaced
frame_rate: Frame rate
-6 = No signal,
0 = 23.98 [Hz], 1 = 24 [Hz], 2 = 25 [Hz], 3 = 29.97 [Hz], 4 = 30 [Hz],
5 = 47.95 [Hz], 6 = 48 [Hz], 7 = 50 [Hz], 8 = 59.94 [Hz], 9 = 60 [Hz]
dot_clock: Dot clock
-6 = No signal, 0 = 27 [MHz], 1 = 74.1758 [MHz], 2 = 74.25 [MHz],
3 = 148.3516 [MHz], 4 = 148.5 [MHz]
pixel_repetition: Pixel Repetition
-6 = No signal, Value other than “-6”: Pixel repetition value
sdi_type: SDI format
-4 = Data error, 0 = HD-SDI, 1 = SD-SDI, 2 = 3G-SDI Level A,
3 = 3G-SDI Level B, 4 = 3G-SDI Level B (2xHD)
mapping_structure: Mapping structure
0 = OFF, 1 = Structure 1, 2 = Structure 2, 3 = Structure 3,
4 = Structure 4, 5 = Dual Stream
vic: CEA-861 video code
0 = N/A, Value other than “0”: CEA-861 video code
h_pol: Horizontal synchronous signal polarity
-6 = No signal, 0 = Negative, 1 = Positive
v_pol: Vertical synchronous signal polarity
-6 = No signal, 0 = Negative, 1 = Positive
