F.6 Alternative frequency and announcement signalling - coding example
Situation
Broadcaster A transmits to the UK and to North America excluding the US.
Figure F.2: Coding Example for Alternative Frequency and
Announcement Signalling - regions and CIRAF zones
The service is available:
1)On SW freq. 1, DRM daily from 16:00 to 02:00 UTC using Service identifier 1 (all marked regions).
2)On SW freq. 2, DRM daily from 12:00 to 18:00 UTC using Service identifier 1 only Canada, Greenland, UK. This DRM multiplex is synchronous to the first one.
3)On SW freq. 3, AM daily from 16:00 to 02:00 UTC (no Service identifier, all marked region).
4)On MW DRM, UK, daily, 24 hours.
5)On FM in several parts of UK, using many different frequencies, normally daily, 24 hours, but sometimes there is a different programme on this network (e.g. sports coverage) but a different PI code is then being used.
6)On FM in London on 2 different frequencies, daily, 24 hours.
7)On FM in a City in North America, weekdays from 18:00 to 22:00 UTC, weekend from 12:00 to 16:00 UTC.
8)On DAB, daily, 24 hours, in the UK only.
9)In the UK, traffic messages can be obtained from a different service on DAB, daily, 24 hours a day.

10)In North America the receiver should tune to the DRM transmission of Broadcaster B when no transmission is available.
Encoded SDC Entities
Schedules (SDC entities type 4)
•Schedule Id 1 | Day Code = 1234567 | Start = 00:00 UTC| Duration = 24 h
alternative coding for the same information:
Schedule Id 1 | Day Code = 1 | Start = 00:00 UTC| Duration = 7×24 h (means: 24 h, daily).
•Schedule Id 2 | Day Code = 1234567 | Start = 16:00 UTC | Duration = 10 h.
•Schedule Id 3 | Day Code = 1234567 | Start = 12:00 UTC | Duration = 6 h.
•Schedule Id 4 | Day Code = 12345 | Start = 18:00 UTC | Duration = 4 h.
•Schedule Id 4 | Day Code = 67 | Start = 12:00 UTC | Duration = 4 h
(means 18:00 to 22:00 UTC on weekdays and 12:00 to 16:00 UTC on Saturday and Sunday).
