5.Proposed revision to Recommendation N.62
TESTS TO BE MADE DURING THE LINE-UP PERIOD THAT
PRECEDES A TELEVISION TRANSMISSION
Insert the following new section 2 in the Recommendation and renumber
the existing sections:
"2. Test signal source identification
All full field test signals as described in this Recommendation should
be superimposed with an identification which includes the point of origin and
the name of the sending authority. It 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
station is not an internationally recognized language then the identification should
be displayed not only in the local language of the station concerned but also in one
of the internationally recognized languages."
Indicate in the existing Table 2/N.62 the following limits for baseline
distortion:
ITC/earth station: ± 1%;
Terrestrial only for 525-line: ± 1%;
Terrestrial only for 625-line: ± 3%.
Change the existing Note b) to Table 2/N.62 to read:
"b) Test objectives given in columns 3a, 3b and 5 refer to temporary
circuit sections and circuits provided by INTELSAT
satellites and relate to expected performance in global
beam utilizing earth stations having G/T of 40.7 dB/K
and elevation angles of 10°. Different figures may be
appropriate when other satellites, earth station sizes
and elevation angles are employed."
Add an additional note as follows:
"Note - Under study."
