Teletext pass-through
Teletext pass-through is possible if a valid input teletext subtitle is present and input and
output video standards are the same. For SD video that uses a large number of WST VBI
(where the VBI may have multiple lines of WST and 2 Timecode lines) the unit can
encode/decode/transcode up to 15 lines of WST. In up and down conversion applications, this
would use up to 3 RDD-08 (OP47) packets. RDD08 OP47 allows for 15 lines of WST to be
encoded. SMPTE2031 allows only 5 lines of WST to be encoded.
