EN530 HDTV Smart Encoder IV
Load XDS Packet
<CTRL+A>P Packet Duration Content [Priority] <ENTER>
Creates an XDS packet and loads it into the XDS queue. The Encoder will
begin inserting the packet immediately.
Packet
sets the XDS Class and Type of the packet that will be created. If a
new packet is loaded with the same Packet ID as an existing packet in the
queue, the pre-existing packet will be deleted; if the new packet is a
Program Name or Program ID packet, all program-specific packets will be
deleted from the queue. A packet loaded into the Encoder with the Load
XDS Packet command has local priority; in output signals, it will replace
all upstream packets of the same Class and Type.
The Packet parameter should be entered as Class immediately followed by
Type in the way shown in the table below. Leading zeroes may be omitted.
The Class and Type of a few of the most commonly used XDS packets are
shown in the following table; for a complete list refer to EIA-608B.

Duration
sets the transmission duration of the newly created packet. When
a packet’s duration period expires, it will be deleted from the XDS queue.
A duration setting of –1
will cause the packet to be inserted until it is
deleted by a future command. An integer setting (i.e. 100) will be
interpreted as the number of times to output the packet before deleting it.
An Elapsed Time setting (i.e. 00.45.00), will cause the packet to be inserted
for that length of time, beginning when the command is entered, and then
deleted.
Content
sets the information content of the packet. Content can be entered
in ASCII text enclosed in curly braces, { }, or in ASCII Hex notation. A
checksum need not be enclosed, as the Encoder will calculate it
automatically before insertion.
