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:                    ñ 1%;

       Terrestrial only for 525-line:        ñ 1%;

       Terrestrial only for 625-line:        ñ 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   10ø.   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."
