Note:
4.13.1 VBI Formatting Features
4.13.1.1 VPS Features
4.13.1.2 WSS Features
4.13.1.3 WST Features
4.13.1.4 Closed Caption Features
The WST - Teletext C and D (525 lines /60 Hz) formats (NATBS - MOJI) may be covered by the
WST - Teletext B (525 lines -60 Hz) format.
Video Programming System (VPS) data complies with ETSI specifications.
Wide Screen Signaling (WSS) data complies with ETSI specifications.
World System Teletext (WST) data complies with ETSI specifications. The searched WST format is
unique at a given time and is programmed by software through register-based control bits (50 Hz or
60 Hz, etc.).

Search of VPS data on TV line 16 of each field
Optional Extended VPS data on three TV lines (15,16 and 17) of each field
Search of VPS data regardless of the field information
Recognition of Start code
Sampling and decoding of bytes 5 and 11 to 14
Bi-phase code check
Generation of bi-phase correctness flags
Search of WSS data on TV line 23 of each field
Optional Extended WSS data on four TV lines (21, 22, 23 and 24) of each field
Search of WSS data regardless of the field information
Recognition of Start code
Sampling and decoding of relevant 14 bits
Bi-phase code check
Generation of bi-phase correctness flags
Search of WST data starting at TV line 6 for 525-line broadcasts, or TV line 318 for 625-line
broadcasts.
Optional Extended WST data search starting at 2nd TV line (register-based control bit).
Recognition and check of usual WST frame code (27h).
Optional recognition and check of programmable extended frame code (register-based value -
but the three LSBs must be kept at ‘1’).
Recognition of all packets or recognition of only Service Packets X/30 and X/31 (register-based
control bit).
Hamming decode & check of Magazine and Page bytes for usual frame code.
Split of Magazine & Page data in two separate bytes (1st byte is for Magazine, 2nd for Page).
Search of CC data during line 21 (NTSC) or line 22 (PAL), regardless of the field information.
Optional Extended slicing during all the VBI (line 5 to 25 /NTSC or 2 to 25 /PAL), regardless of
the field information.
Recognition and check of usual CC Frame code (11000b).
Recognition and check of tighter CC Frame code (C2h).
