5. Upstream TC+F1+F2: This does the same as # 4, except time code is added.
Three “marker characters” are used to identify the data being transmitted: 90h
(144d), A0h (160d), and B0h (176d). When the time code changes, the following
is transmitted: 90 hhmmssff (where hhmmssff is an ASCII character string
representing the time code value). When field 1 caption data is decoded, the
following is transmitted: A0 bb (where bb is two bytes of caption data, and each
byte can be 00h to 7Fh). When field 2 caption data is decoded, the following is
transmitted: B0 bb (where bb is two bytes of caption data, and each byte can be
00h to 7Fh). Examples output (hex):
90 30 31 30 30 30 30 30 30 = 01:00:00:00
(No caption data transmitted, so both fields were “null”)
90 30 31 30 30 30 30 30 31 = 01:00:00:01
A0 14 20 = field 1 data: 14 20 (RDC CC1)
B0 15 26 = field 2 data: 15 26 (RU3 CC3)
90 30 31 30 30 30 30 30 32 = 01:00:00:02
A0 14 70 = field 1 data: 14 70 (PAC)
B0 14 70 = field 2 data: 14 70 (PAC)
6. Encoded F1: Same as # 2, except that the caption data comes from outgoing
video instead of incoming video.
7. Encoded F2: Same as # 3, except that the caption data comes from outgoing
video instead of incoming video.
8. Encoded F1+F2: Same as # 4 except that the caption data comes from outgoing
video instead of incoming video.
9. Receive: This selection directs the HDE3000 to receive data on this com port
and pass the received data to the function running on the other com port. This
function is only required to support running “source = Time Taylor” on the other
com port.
10. Time Taylor: This selection directs the HDE3000 to receive commands from the
Time Taylor. When this source is selected, this function takes control of the
encoder, buffers the caption data received on the other com port (the other com
port must be set to “source = receive”), and encodes the buffered caption data at
the proper time codes.
For more information on setting up the HDE-3000 for the Time Taylor see section 7
“Time Taylor” of this manual.
