GLOSSARY OF STANDARDS
OVERVIEW
8083XDS-AD Analog and SD-SDI XDS Encoder
The Time Zone packet (0704) encodes the time zone offset from UTC time
and contains a flag bit (DSO Flag) that is to be set when the entire area
served by the signal observes Daylight Saving Time. When the DSO Flag
bit is set to Off, it means that the VCR will ignore the DST Flag bit in the
Time of Day packet. The Time Zone packet must be inserted locally at
each affiliate in order to encode the correct time zone offset for the region.
See application note AN3 at the back of this manual for more information
about encoding time in XDS packets.
This manual is organized into 6 chapters: Overview, Installation, Operation,
Serial Command Protocol, Technical Description, and Troubleshooting.
There are also two application notes in the rear of the manual.
If you are confused by any terminology used throughout the manual,
please refer to the Glossary of Terms in Chapter 1.
EIA (Electronic Industries Alliance):
associations representing various facets of the electronics industry. Each
of these EIA Sector Associations manages its own standards-setting
programs under EIA, the umbrella organization.
EIA-608-B:
This EIA standard serves as a technical guide for those
providing encoding equipment and/or decoding equipment to produce
material with encoded data embedded in Line 21 of the vertical blanking
interval of the NTSC video signal. It is also a usage guide for those who will
produce material using such equipment.
EIA-708-B
defines the coding of DTV closed captions (DTVCC) as they
are delivered in an ATSC signal, and also defines the Caption Distribution
Packet (CDP). This structure contains fields that can hold: EIA-608-B data
for use if the video is converted to standard definition analog; DTV captions
for use in an ATSC program; Caption Descriptors; and Time Code. The
CDP is the basic unit of data that is transported through the professional
portion of a DTV plant. As such, it is central to the methods discussed in
this document.
