6.Proposed additions to Recommendation N.63
TEST SIGNALS TO BE USED BY THE BROADCASTING ORGANIZATIONS
DURING THE PREPARATORY PERIOD
Add a third and fourth alinea to the Recommendation as follows:
"All test signals transmitted prior to the actual television
transmission, being full field or otherwise, should be superimposed with
the identification of the broadcaster and location from where the test signal is
originating. This identification may be transmitted either in monochrome, or in
colour, according to preference or to suit the technical requirements of the
particular test signal being transmitted. If the local language of the originating
source is not an internationally recognized language then the identification
signal should be displayed not only in the local language of the country concerned
but also in one of the internationally recognized languages.
When a full field signal is transmitted simply as a means to check link
or tandem connection continuity, it may comprise any suitable composite video
signal (such as test card, pulse and bar or other suitable picture or pattern)
provided that it contains specific signal components that include Peak White,
synchronizing pulses and the identification signal (as previously described) of the
station or broadcaster transmitting the signal. The composite signal (colour bars
plus captions, etc.) must not exceed 1 volt (peak-to-peak) in order to preclude
interference with adjacent video channels, particularly on half transponder
satellite operation."
Move the existing third alinea to the end of the Recommendation.
