Selection has a documented control path
The dash.js documentation describes MPD information and a steering server supplying the required steering manifest. BaseURL service locations help identify delivery choices. An actual implementation needs those relationships; a list of alternate hostnames alone does not establish that steering is configured.
Imagine a programme continues while its media requests move from delivery host A to host B. That can be an intended selection change. It is not automatically a subscription change, a different programme or evidence that the first host was globally unavailable.
A new path still needs to work
The chosen destination must satisfy its own connection, access and resource requirements. A successful steering response does not prove that every later segment can be retrieved and decoded. Preserve the selected location and the outcome of the media requests that follow.
Likewise, an alternate source does not by itself guarantee invisible failover or lower delay. The player state, timing and media continuity still matter. A publisher should verify the intended transition rather than advertise universal recovery from the existence of a steering feature.
Keep viewer and operator actions separate
Viewers should use the service's documented entry route and report source-transition symptoms through support. Do not replace private media hosts manually or share signed resource addresses to test guessed alternatives. The authorised distributor controls which delivery locations belong to its intended path.
For a developer report, retain manifest steering information, returned choice, relevant player version and subsequent request or playback outcome. This reference describes dash.js behaviour and does not claim IPTV Australia operates multiple delivery providers or a steering service. It also does not report a live transition test. The useful distinction is configured source selection versus successful media continuation, with each stage supported separately.
Questions about this guide
Does another delivery hostname imply another subscription?
No. It can be part of the same distributor-controlled path.
Does configured steering guarantee seamless failover?
No. The selected media path and transition still need verification.
