uint8_t | data [56] |
This structure holds one scan line of sliced vbi data.
For example the contents of NTSC line 21, two bytes of Closed Caption data. Usually an array of vbi_sliced is used, covering all VBI lines of the two fields of a video frame.
uint32_t vbi_sliced::id |
A VBI_SLICED_ symbol identifying the data service. Under cirumstances (see VBI_SLICED_TELETEXT_B) this can be a set of VBI_SLICED_ symbols.
uint32_t vbi_sliced::line |
Source line number according to the ITU-R line numbering scheme, a value of 0
if the exact line number is unknown. Note that some data services cannot be reliable decoded without line number.
uint8_t vbi_sliced::data[56] |
The actual payload. See the documentation of VBI_SLICED_ symbols for details.
