11. Merged Feeds

1. Purpose

Merged Feeds build one logical output from multiple source feeds.

Recommended model:

1. keep physical sources in Feeds,
2. expose combined output via merged feeds where needed.

2. Merged feed options

Each merged feed has:

1. Name
2. Source Feeds (receiverIds)
3. Enabled
4. Visible in Radar Dropdown
5. ICAO Timeout (ms)
6. Ignore Aircraft with No Position

3. Runtime logic

For each ICAO:

1. one source feed is selected as active owner,
2. duplicate frames from other sources are suppressed,
3. if active source is silent longer than ICAO Timeout, ownership may switch to another source.

4. ID namespace

Merged feed IDs use dedicated range starting from 10000, reducing collision risk with regular feed IDs.

5. Workflow notes

1. Feed editor contains shortcut Add to merged feed for smart-profile ports.
2. Final source assignment should be verified in Merged Feeds panel.
3. Merged feeds can be selected as source in Rebroadcast Servers.
