Blocking Upstream Xds Packets - evertz 8084 Instruction Manual

Time of Day and Time Zone packets behave differently than other XDS
articles when defined. The defined packet contents will be ignored; the
encoder will generate the time of day packet data from the current internal
time.

The parameter rc identifies number of times the packet will be repeated.
Values of 9999 or FFFF indicate that the packet should be repeated
indefinitely. A packet's repeat count will be decremented each time it is
output.
The parameter data is the information bytes of the packet. This data is
entered in ASCII Hex format. For example to enter the letter A enter a 4
followed by a 1 (the hex ASCII code for A is 41)
The XDS article length is checked for the following commonly used articles:
Program ID (0101), V-Chip Content Advisory (0105), Station Call Letters
(0502), and Time Zone (0704). If the article length is not in the valid range
for the packet type, the encoder will reject it. This length checking does not
apply to XDS packets from upstream, only XDS articles that are entered
using the ^AP command from a serial port.
Examples: ^AP<sp>0103<sp>10<sp>41424344<cr>
Sets the program name packet to ABCD and repeat
packet ten times.
^AP<sp>0701<sp>9999<sp>456A4548474A<cr>
Time Of Day packet indicating the current UTC time
is 10:05 am on Saturday, August 5
ON. The packet will be repeated indefinitely.
^AP<sp>0105<sp>9999<sp>486D<cr>
Program rating packet setting the rating system to
"TV Parental Guideline", rating of TV-14 with V and L
bits set.
Other V-Chip ratings may be encoded using the
information in section 6.1.17.

Blocking Upstream XDS Packets

Upstream XDS packets can be removed entirely from the data stream,
without having to insert new XDS data of the same type. This is
accomplished using a variation of the ^AP serial interface command. This
feature is particularly useful for removing unwanted Time-of-Day packets,
Time Zone packets, etc. off of pre-encoded material.
To remove a specific XDS packet, use the ^AP command to enter an XDS
article with the packet id of the packet you want to remove, a repeat count
Revision 1.6.6
The packet will be repeated indefinitely.
