Functional Description

2.7VBI 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.
