NOTES…
1. Any type of valid VBI can be on any line, even if it is not usually associated with that line.
2. 625-line fields start on the leading edge of the first vertical sync (broad) pulse. Therefore, the first
half of line 313 is in field 1 and the second half is in field 2.
3. An MPEG frame is 576 lines when formatting 625-line format pictures.
4. Line 23 is the Wide Screen Signalling line. It carries information which defines the picture Aspect
Ratio.
5. ETS 300 294 is the specification which describes WSS.
6. EN 300 472 is the specification associated with System B Teletext (World System Teletext).
