This structure holds one scan line of sliced vbi data.
<p>
For example the contents of NTSC line 21, two bytes of Closed Caption data. Usually an array of <a class="el" href="structvbi__sliced.html" title="This structure holds one scan line of sliced vbi data.">vbi_sliced</a> is used, covering all VBI lines of the two fields of a video frame. <dl compact><dt><b>Examples: </b></dt><dd>
