A plain-language reference for the terms you meet around RePro Pulsar. Most show up as small coloured pills, badges, and tooltips rather than full words, so use this page to decode what you're looking at.

The terms appear throughout the main window: the INPUT pill at the left of each row names the source type; the two OUTPUT pills on the right name each output; and clicking a pill opens its config window. Orbit terms live in Orbit Device Control (opened from the footer), and the benchmark opens from Tools → Pipeline Benchmark… in the menu bar.

A few terms below only show once you switch the feature on. Where that's the case it's noted in one line — see Settings and configuration.

Quick how-tos

Decode the coloured pill at the left of a row

1. Look at the small coloured pill at the row's left edge.
2. Read the colour:
   • Blue = NDI
   • Green = GUI (screen/camera)
   • Amber = FILE
   • Cyan = SRT-in
   • Purple = EXT (capture card)
   • Orange = UE (Unreal Engine)
   • Dark gold = GEN (test generator)
3. Click the pill to change the source type — only while the row is stopped.

See Introduction & core concepts.

Tell whether an output goes out as SRT, NDI, or SDI

1. Look at the Stream 1 / Stream 2 output pills on the right of the row.
2. The pill text reads SRT, NDI, or SDI:
   • SRT sends the stream over the internet or LAN.
   • NDI puts it on the local network for other NDI apps.
   • SDI plays it out of a DeckLink card.

See Outputs: SRT and NDI.

Understand Caller vs Listener for SRT

1. Open the SRT config (click the SRT output pill, or the SRT-in source pill).
2. Choose Caller if Pulsar should dial out to a remote listener — you supply their srt:// URL.
3. Choose Listener if Pulsar should wait for someone to connect — you supply a free port and share your IP:port.
4. Raise Latency on lossy networks (default 400 ms), and optionally generate a Passphrase to encrypt the link.
