of the available video modes in VV5410/VV6410.

8.3.1

Blank lines

In addition to padding between data lines, actual blank data lines may appear in the positions indicated above. These lines begin

with start-of-blank-line embedded control sequences and are constructed identically to active video lines except that they will

contain only blank bytes, 07H, (expressed as 01CH in 10bit form).

8.3.2

Black line timing

The black lines (which are used for black offset calculation) are identical in structure to valid video lines except that they begin

with a start-of-black line code and contain either information from the sensor black lines or blanking data.

By default VP3 mode (see mode_select[24] for details) is selected. It is an option in any of the VP3 modes to select the additional

black lines to be output (line 3-8). If the VP3 mode is not selected then all the black lines are enabled - no blank lines are output.

Internally there is the concept of dark lines - to be used for dark offset cancellation (see following diagrams to identify their

position within the frame timing model), however externally the dark lines share the same line type code as the black lines.

8.3.3

Padding Lines and Fields

The user may choose to extend the inter-field period by increasing the field length by writing to serial registers 97 & 98. In this

event, the appropriate number of additional black or blank lines is inserted between the End Of Field (EOF) line and the Start Of

Field (SOF) line. This means that the distance between SOF and EOF will remain constant.

The user can also extend the line length by writing to serial registers 82 and 83. The line length padding is inserted after the EAV

sequence, ensuring that the distance between the SAV and EAV sequences will remain constant.
