AHTC:

Each receiver has two channels. An entry is made for each channel and the ID must be continuous. The host name and main_structure_element_id are set in each entry and are the same for each receiver. Video teams are assigned here to the receivers.

Example:
id  stream_name    main_structure_element_id  team_id  host_name
