Both SSE (Server Sent events) and Websockets allow real-time messaging from a server to a client.
Do these stream protocol work when the browser is in the background and another programs are in focus, especially in mobile browsers?

Reset to default 3Yes. At least WebSocket.
Open this demo in browser 1, click on "open 2nd instance", copy the link to browser 2, put browser 1 to background and click "publish" in browser 2.
The demo will work on Chrome for Mobile (on Android) also. I have just tested: it'll receive messages a) when switching to another tab, and then switch back, and also b) if you open another activity (app), and then return to Chrome.
You can also try the other demos. Other than audio output with the "beatbox demo", everything will work on Chrome Mobile. Note that with the "beatbox demo", you can still use the smartphone as a controller .. it's just the audio output which has issues.

Not on all platforms. According to Keep WebSocket alive in Mobile Safari it is not possible in mobile safari.
