5.6.2 XDS CGMS Setup Menu
This menu allows you to encode CGMS data as part of the XDS service. CGMS (Copy
Generation Management System) is described in section 9.5.1.8 of the EIA-608-B
specification. The EIA-608-B specification also references “The Digital Video Recording Act”
for more information about CGMS.
There are three possible settings for the “CGMS-A” (Copy Generation Management
System – Analog) parameter as follows: “Copying Allowed”, “One Copy Allowed”, and “No
Copying Permitted”.
When the above CGMS-A parameter is set to “No Copying Permitted”, then the “APS”
(Analog Protection System) parameter is valid. There are four possible settings for the
“APS” parameter as follows; “No APS”, “PSP on, Splt Brst Off”, “PSP on, 2 Ln Splt Brst”, and
“PSP on, 4 Ln Splt Brst”. When “APS” is enabled, “PSP” (Pseudo Sync Pulse) is on, and
the “Split Burst” can be set to “off”, “2 Line”, or “4 Line”. When the CGMS-A parameter is
set to “Copying Allowed” or “One Copy Allowed”, then there is no APS, so the “APS”
parameter should be set to “No APS”.
The “ASB” (Analog Source Bit) is specified in EIA-608-B. This bit can be on (“1”) or off
(“0”).
