The allocation of data to the different lines of the display follows the mappings for the different video
standards detailed in the relevant SMPTE standards:
SMPTE 372 for 1.5Gb/s Dual-Link video
SMPTE ST 425-1 for sub-1080-line 3G Level B Dual-Link and Level B Dual-Stream video
SMPTE ST 425-3 for 1080/2160-line 3G video
SMPTE ST 425-5 for Quad-Link 3G video
SMPTE ST 2081 for 6G video
SMPTE ST 2082 for 12G video
The lines of the block are numbered using an n:m format where n identifies the cable on which the
Input is being delivered and m identifies the ‘Virtual Interface’ on that cable (as define in the SMPTE
standards) corresponding to the Interface. The role in the final image played by each Input is indicated
by the bar shown to the right of the n:m number which is coloured according to the colouring scheme
used in the appropriate SMPTE standard.
The current cursor position is indicated by copper-coloured boxes around the relevant data. When
the SMPTE Sample cursor is selected, a single box is shown on each horizontal block, picking out
the selected sample. When the Active Picture cursor is selected, one or more smaller boxes may be
shown, picking out the different sample elements that contribute to the currently selected pixel. The
arrangement of smaller boxes shown is strongly dependent on the video standard of the signal that is
being analysed, in particular whether the Sampling is 4:4:4, 4:2:2 or 4:2:0.
When the SMPTE Sample cursor is selected When the Active Picture cursor is selected
The current cursor position is maintained across the different displays and the different cursor
selections so that the user can follow the contributions being made from different bit periods to any
pixel. Please refer to the appropriate SMPTE standards for details of data sample structure.
