XDS Insertion
Extended Data Services (XDS) is an NTSC Field 2 data channel that provides information to viewers about the
program that is being aired. XDS is used to transmit FCC-mandated program ratings to allow viewer V-chip
filtering. XDS is a part of the CTA-608 standard for SD broadcasts, and should be included in the 608
compatibility bytes of CTA-708 compliant HD broadcasts.
XDS insertion is typically controlled through a serial
connection to an automation server and is compatible with Imagine/Harris, Snell, and EEG’s XDS Xpress
solution.
XDS data packets can be loaded into the Encoder’s queue with one simple command, and be held for any
specified time period. Each individual packet type can be independently set for upstream or local priority,
and permanent packets can be stored in Non-Volatile Memory and inserted automatically whenever the
Encoder is operating.
A List of XDS commands may be found in the Command Reference section of this
manual.
