2.7 VBI Data Processor

The TVP5147M1 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 (Gemstar) 1x/2x. Table 2-6 shows the supported VBI system.

These services are acquired by programming the VDP to enable the reception of one or more vertical

blank interval (VBI) data standard(s) during the VBI. 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 the high data bandwidth, teletext results are stored in FIFO only. The

TVP5147M1 decoder provides fully decoded V-Chip data to the dedicated registers at subaddresses 80

0540h−80 0543h.
