Video Format Menu
The Video Format menu items are described below.
Video A, B, C, or D Format
The Video “A, B, C, D” Configure menu is used to automatically or manually select
the video format reference standard for the selected input. The format selection
determines the unit of measure and the critical amplitude limits for the input. The
default selection, AUTODETECT, is used to automatically detect the format of the
input signal.
Video A, B, C, or D Structure
The VIDEO “A, B, C, D” Structure menu is used to configure the signal handling path
to a 10-bit or 12-bit RGB or YCBCR sampling structure. 12-bit modes are not available
with formats 1080p/60, 1080p/59.94, and 1080p/50. 4:4:4 and 4:2:2 are the format
rates selected with the 10-bit and 12-bit sampling structures. 4:2:2 is only available
with 12-Bit YCBCR. The selections are:
• AUTO 10 bit YCbCr 4:2:2: The sampling structure is determined from the Video
Payload Identifier. If there is no detected VPI, a 10-bit YC
B
C
R
sampling structure
will be assumed.
• 10-bit YCbCr 4:4:4: The signal handling path will be configured for a 10-bit
YC
B
C
R
mode of operation.
• 10-bit RGB 4:4:4: The signal handling path will be configured for a 10-bit RGB
mode of operation.
• 12-bit YCbCr 4:4:4: The signal handling path will be configured for a 12-bit
YC
B
C
R
mode of operation. This selection is only available for 3Gb/s HD, when a
TVM-VTM-3GB board is detected for the appropriate channels.
• 12-bit RGB 4:4:4: The signal handling path will be configured for a 12-bit RGB
mode of operation. This selection is only available for 3Gb/s HD, when a
TVM-VTM-3GB board is detected for the appropriate channels.
• 12-bit YCbCr 4:2:2: The signal handling path will be configured for a 12-bit
YC
B
C
R
mode of operation. This selection is only available for 3Gb/s HD, when a
TVM-VTM-3GB board is detected for the appropriate channels
Dual Link
Inputs A and B and C and D have DUAL LINK selections. Selecting a format with
DUAL LINK forces the Input A YCBCR format to link with Input B or the Input C
YCBCR format to link with Input D. Inputs A or B cannot be linked to inputs C or D,
and inputs C or D cannot be linked with inputs A or B.
The TVM-VTM-DLK expands the Dual Link capability. Inputs A and B and C and D
contain another DUAL LINK selection: RGB. Selecting a format with DUAL LINK
can force Input A to include the YCBCR or RGB format to link with Input B or the
Input C YCBCR or RGB format to link with Input D. Inputs A or B cannot be linked to
inputs C or D, and inputs C or D cannot be linked with inputs A or B.
