7.4 Video Frame Composition
Each frame of video sequence comprises 2 fields. Each field of data is constructed of the following sequence of data lines.
1. A start of field line
2. A number of black lines
3. A number of blank (or dark) lines
4. A number active video lines
5. An end of field line
6. A number of blank or black lines

Table 9 : Field and Frame Composition
Each line of data starts with an embedded control sequence that identifies the line type (as outlined in). The control sequence is
then followed by two bytes that contain a coded line number. The line number sequences starts with the start-of-frame line at 00H
and increments one per line up 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 visible video lines as a number of null bytes may be
inserted between successive data lines.
There are two figures (Figure 7 - Figure 8) on the following pages that show line type field construction.
7.4.1 Blank lines
In addition to padding between data lines, actual blank data lines may appear in the positions indicated above. These lines begin
