- 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."
