When
a program is being captioned live and reaches a commercial break or the
end of the program, the captioner must send a command to enable the encoder
that is processing the captions to accept other data. If the captioner
neglects to send this enabling command when they finish captioning a segment
or program, the captions on the next commercial or program will not be
able to access the encoder, and will not appear. The technical staff at
the broadcast site must be alert for this situation. Also, the commercials
themselves might not be captioned. |
