2.10 VBI Data Processor
The TVP5160 VBI data processor (VDP) slices various data services like teletext (WST, NABTS), closed
caption (CC), wide screen signaling (WSS), program delivery control (PDC), vertical interval time code
(VITC), video program system (VPS), copy generation management system (CGMS) data, and electronic
program guide (EPG or Gemstar) 1x/2x. Table 2-9 shows the supported VBI system.
These services are acquired by programming the VDP to enable the reception of one or more VBI data
standard(s) in the vertical blanking interval. The VDP can be programmed on a line-per-line basis to
enable simultaneous reception of different VBI formats, one per line. The results are stored in a FIFO
and/or registers. Because of its high data bandwidth, the teletext results are stored in the FIFO only. The
TVP5160 decoder provides fully decoded V-Chip data to the dedicated registers at subaddresses
800540h through 800543h.
