Bt848/848A/849A provides a complete solution for capturing and decoding Verti-
cal Blanking Interval (VBI) data. The Bt848/848A/849A can operate in a VBI Line
Output Mode, in which the VBI data is only captured during select lines. This
mode of operation enables concurrent capture of VBI lines containing ancillary
data and normal video image data.
which every line in the video frame is treated as if it was a VBI line. This mode of
operation is designed for use with still frame capture/processing applications.
The Bt848/848A/849A provides a two-wire Inter-Integrated Circuit (I
face. As an I
card, such as a TV tuner. Serial clock and data lines, SCL and SDA are used to
transfer data at a rate of 100 Kbits/s.
In addition, the Bt848/848A/849A supports a VBI Frame Output Mode, in
