5.3 Video timing reference and status/configuration data
Each frame of video sequence is made up of 2 fields. Each field of data is constructed of the following
sequence of data-lines.
1. A start-of-field line
2. 2 ‘black lines’ (used for black level calibration)
3. A number of blank lines
4. A number active video lines
5. An end of field line
6. A number of blank lines.

Table 5.4 : Field and Frame Formats
Table 5.4 details the number of each type of data-lines for NTSC, PAL and CIF output formats when the
border rows and columns, are output, and not output, on the data-bus.
Each line of data starts with an embedded control sequence, which identifies the line type (as outlined in
Table 5.2). The control sequence is then followed by two bytes which, except in the case of the end-of-frame
line, contain a coded line number. The line number sequences starts with the start-of-frame line at 00H, and
increments, one per line, until the end-of-frame line. Each line is terminated with an end-of-line embedded
control sequence. The line start embedded sequences, must be used to recognise data-lines, as a number
of null bytes may be inserted between data-lines.
5.3.1 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 (07 H).
5.3.2 Black line timing
The black lines (which are used for black level calibration) are identical in structure to valid video lines except
that they begin with a start-of-black line sequence and contain either information from the sensor ‘black lines’
or blank bytes (07H).
