The period of time between the end of one video field and the beginning of the next. During this time, the electron beam in a camera, monitor, or projector is turned off (blanked) while it returns from the bottom of the screen to the top. The portion of the video signal that represents this time period may also be called the vertical interval.
Time interval during which vertical blanking is applied. E. g. , in 625 line systems the Vertical Blanking width is 25 lines plus Horizontal Blanking Interval. Synonyms: Field Blank; Vertical Blank
The portion of the video signal that occurs between the end of one field and the beginning of the next. During this time, the electron beams in the monitors are turned off (invisible) so that they can return from the bottom of the screen to the top to begin another scan.
Indicates the vertical blanking period between each video field which contains additional scan lines above the active picture area into which non-picture information (captioning, copy protection and other control signals) may be embedded.
Non-visible (off-screen) part of a video picture signal.
Synonymous with vertical blanking.
indicates the vertical blanking period between each video field. Contains additional scan lines above the active picture area into which non-picture information (captioning, test and control signals, user bits) can be recorded.
Non-visible part of TV image used for additional information, such as Timecode or ‘closedâ€(tm) Subtitles.
(n.) The raster lines that are precluded by a video signal standard from containing a picture. You can convey those vertical interval lines that are not required to be blanked as test signals (VITS), a reference signal (VIRS), timecode (VITC), closed captioning data (CC), teletext, or other information.
