Models 8084/8084AD/8085 Closed Caption Encoder Manual
6.1.17 How can I encode XDS / V-Chip "Content Advisory" or
"Program Rating" packets?
See section 4.6 of this manual for instructions on how to enter any XDS
packets into the XDS data stream. The manual does not attempt to provide
a comprehensive list of valid XDS packet types. The reader is encouraged
to refer to the EIA-608-B standard for the currently supported and required
packet types. For the V-Chip program rating packet, EIA-744-A serves as
an addendum to EIA-608-A.
If there is no automation system or XDS software controlling the insertion
of V-Chip program rating packets, the 8084 and 8084AD have built-in
facilities for inserting a default V-Chip program rating locally from the front
panel setup menu system. Refer to section 3.2 for instructions on how to
configure this feature. (This feature is not available in Model 8085 DTV
Caption Encoder)
At the time of writing, Evertz Microsystems provides 808x Configware
software free of charge that can be used with Evertz captioning encoders
to manually encode many different XDS packet types. Evertz also sells
MetaCast 2 software that allows you to create a play list that matches your
program schedule, so that you can automatically encode different V-Chip
and XDS packets for each program segment. See the Evertz Web site
(www.evertz.com) for complete information.
If you want to encode V-Chip rating packets using the serial commands
you can follow this procedure.
The command to enter V-Chip packet "articles" is ^AP (see full description
in section 4.6.1 of this manual). The basic form of this command is:
^AP<sp>0105<sp>9999<sp>xxxx<cr> where ^A is control-A (0x01)
character, <sp> is a space character, <cr> is a carriage return (0x0D), and
"xxxx" would be replaced with the rating code as shown in the following
table. There are four different rating systems, each with their own sets of
codes.
