The values accepted are:

0: for 4K output (if "2K All Outputs" not set)

1: for 2K output on output 1 only.

The manual configuration bit is bit 3 (0x08) in register 0x00, set to value 0 for 4K output and to

value 1 for 2K output, using the procedure described above in Manual Configuration.

4.5.5 3D/48fps Output

The MB-4K only output a 24fps signal. When the MB-4K receives a single link 4:2:2 10b YCxCz

video on input A, it automatically goes into a 3D/48fps mode. In this mode, only the input A in

taken into account.

Starting with firmware version MB 0.01k, there are 2 outputs possible in this 3D/48fps mode:

4:2:2 10b YCxCz single link output at 24fps on each output A (copied on the

corresponding output B). This is the default mode.

4:4:4 12b XYZ dual link at 24fps on output A and B combined

The configuration file for this setting is "3D_444_output" in /doremi/etc/beluga, see Boot

Configuration Files.

The values accepted are:

0: 3D 4:2:2 10b YcxCz outputs

1: 3D 4:4:4 12b XYZ outputs

The manual configuration bit is the bit 4 (0x10) of register 0x00 to 1 (4:4:4 XYZ) or 0 (4:2:2

YCxCz) using the procedure described above in Manual Configuration.

Note 1: Until firmware MB 0.01j (included) only the 4:4:4 12b XYZ output mode was supported.

Note 2: in 2D (24fps) mode, the output is always 4:4:4 12b XYZ dual link.

Note 3: To support a 4K 3D output or a 4K 48fps output, you need to use 2 MB-4K in parallel.

Starting with firmware version MB 0.01k, the MB-4K auto detected which input (A or B) is the

main link (link A) of the Dual Link HD-SDI input, and which is the second link (link B).

When receiving a 3D/48fps single link 4:2:2 10b YCxCz video, the MB-4K always take into

account only the input A.

This allows to use the same connections for both 2D (24fps) and 3D (48fps) configuration when

using 2 MB-4K to support 3D (48fps) playback, as shown in Figure 3:
