3.2.7.2 Inserting a "Default" Program Rating
The encoder can detect the presence or absence of program ratings in the
upstream caption data. By enabling the Local V-Chip Timer, the encoder
will begin to insert the specified program rating only after no upstream
program rating has been detected for the specified time. If an upstream
program rating is detected later, the local rating will automatically be
disabled, allowing the upstream rating packets to pass through the
encoder.
This feature is useful for automating V-Chip rating insertion in broadcast
facilities where there may be a mix of sources that may or may not have
ratings pre-encoded. It is important for broadcasters to always encode a
program rating; some consumer decoders will simply remember the last
rating packet received if the broadcaster simply stops transmitting rating
packets altogether.
3.2.7.3 Compatibility With V-Chip Software
Automation software, such as the Evertz driver for Louth Automation,
MetaCast 2 software, or Evertz XDS Packet Control software, has a higher
priority than the local ratings. If external software sends a new program
rating to the encoder, the Local V-Chip Timer will automatically revert to the
"Insert disable" setting, turning it off. If the operator re-enables the local
rating insertion, unexpected results may occur since two systems will then
be attempting to control ratings insertion.
The Engineering menu is used to configure the advanced operational
modes and hardware configuration items of the Closed Caption Encoder.
This includes selecting baud rate for communications, type of command
emulation, and enabling test message encoding. A ">" symbol to the left
of the main level menu items allows them to be easily distinguished from
the main setup items and the front panel operating messages. The sub-
menu options are shown in lower case to allow them to be easily
distinguished from the main level items.
3.3.1
Setting the Serial Port Baud Rate and Data Format
Two menu items are used to set up the serial port connection parameters.
There is a pair of menu items for each of the ports. A third menu item sets
the port permissions for each port. There is another menu item associated
with serial port B that allows it to be configured for several special
functions.
