The EUMETCast Europe Basic Service channels will be reorganised in the first quarter of 2022.

This reorganisation aims to achieve the following:

  • Optimise the bandwidth usage on EUMETCast Europe First Transponder (E10A-C4) by reducing the capacity allocated to the Basic Service.
  • Simplify the DVB receivers/card setup by reducing the number of PIDs used; PIDs 300 and 301 will be emptied and channels moved to PIDs 100 and 500.
  • Simplify the Tellicast Client setup by reducing the number of channels, removing unused channels, and merging some channels.
  • Reorganise the dataset allocation to the channels for better harmonization with other EUMETCast services (Africa and Terrestrial).

As part of the reorganisation, channels will be renamed in a more meaningful way, following a specific convention indicating the transponder, the EUMETCast service the channel is active on, and the datasets that the channel is carrying — e.g. E1B-GEO-1, where:

  • E1: EUMETCast Europe Transponder 1.
  • B: Basic Service.
  • GEO-1: EUMETSAT Geostationary mission data (e.g. MSG) channel 1.

Note: some channels already follow this naming convention and will, therefore, keep their current names.

The table below provides more details about the migration from old to new channels.

Change implementation phases

In order to allow users to change their setup and migrate from the old to the new channels as smoothly as possible, the change will be implemented in three phases:

Phase 1 (4 weeks starting from 1 February 2022)

The new channels will be added without moving any data flow from the old channels.

A dummy/test file will be disseminated on each of the new channels every 10 minutes, with the following file naming:
<New channel Name>_YYYYMMDDTHHMM00_DUMMY.FILE.CHA (~10 Bytes)
Example: E1B-GEO-1_20220201T120000_DUMMY.FILE.CHA

This will demonstrate that the channels are working and will give users the time to implement the changes needed to receive the new channels and test them.

Users will only be given access to those channels which disseminate the data to which they are subscribed.

In this phase, users will keep receiving the data on the old channels.

User-side configuration changes

  • Users need to make sure that PID 500 is enabled on their DVB receivers/cards, in case this PID is not already enabled.
  • Before the beginning of this phase, EUMETSAT will provide a script that users can download and run to implement the needed changes on the Tellicast configuration (cast-client-channels_bas.ini). The target directory that is already defined in the cast-client-channels_bas.ini will also be used by the new channels.
  • Users are requested to check the cast-client-channels_bas.ini script after executing it, and if the dummy files described above could be an issue for any processing tools running on their station, to change the target directory for the new channel to a different location.

Phase 2 (3 weeks starting from 1 March 2022)

All datasets will be moved to the new channels, except EARS and MSG mission data.

Note: The MSG 6-hourly products will be moved to the new channels.

Phase 3 (22 March 2022)

The remaining data (MSG and EARS) will be moved to the new channels and dissemination will stop on the old ones.

Note: Please be aware that for some of the old channels, the datasets are migrated to more than one new channel, e.g. data currently on EUMETSAT Data Channel 12 will be migrated to E1B-TPC-6, E1B-TPG-1 and E1B-TPL-1. Also, in some cases old channels are merged into one new channel, e.g. EUMETSAT Data Channel 3, EUMETSAT Data Channel 4 → E1B-GEO-4.
