dicates the incoming signal format. If there is no input or
the format is not the correct rate, the following messages will appear on the
second line of the LCD: “No Input Signal” or “Input Signal Error (Check
FORMAT)”.
YCbCr 4:2:2 10b: Indicates the output sampling structure.

Select Level A or Level B as the serial link multiplexing method, or select HD
mode. Use the left (◄)orright(
►) arrow button to select from the Level A,
Level B or HD choices listed below. Press the ENTER button to confirm the
selection. The following figure shows the OUTPUT MODE submenu.

Level A. This is one way of constructing the 3 Gb/s serial data stream, as
described in SMPTE 425. For the mapping structure 1 signals such as 1080p50,
1080p59.94 and 1080p60, a Level A stream looks similar to HD video (as defined
in SMPTE 292), except the data rate is twice as fast. In Level A, the lines
are sent in order, consecutively. For other mapping structures, the video is at a
lower frame rate, but has more bits and/or includes more channels. Refer to the
SMPTE 425 standard for details on the Level A mapping method.
Level B. This is an alternate way of constructing the 3 Gb/s serial data stream, as
described in SMPTE 425. A Level B stream looks similar to dual link (as defined
in SMPTE 372M). The serial data is constructed by interleaving the two links of
the dual link video signal. As a result, some formats will have the s erial data take
two lines worth of time to propagate. This has implications for the effects of the
pathological signals, and can confuse the definition of timing adjustments. Refer
to the SMPTE 372M and SMPTE 425 standards for more information.
2K × 1080. Available in both Level A and Level B mapping, this selection
provides 2048 × 1080 resolution signals, primarily for digital cinema applications.
2×HD. Available in Level B mapping, 2×HD signals pro
vide two standard
SMPTE 292 HD streams in the same format (for example 1080i 59.94). Select
between Test Signal/Test Signal or Test Signal/Black for the two streams.
HD. Available when the HD mode is selected. The output is a 1.485 G b/s
SMPTE 292 compliant signal.
