A preview can request the same live media as a full-screen view. Its small size does not mean it is only a static image or that it avoids connection limits. Check whether moving through the guide starts previews automatically and stop playback when you want to end the session.
Distinguish artwork from moving video
A thumbnail may be a cached image, while a moving preview is actual media playback. Sound is another clue, though a muted preview can still request data. The player’s implementation determines how quickly previous preview sessions are closed.
Be careful during multi-device tests
Leaving a preview running on one television while opening another device can complicate an account comparison. Stop the first player deliberately when the subscription permits only one active stream. Do not assume returning to the channel grid has freed the session.
Choose a quieter browsing mode
If the player offers a documented preview toggle, a list-only layout can reduce unwanted playback while navigating. That is a usability choice rather than a promise of a particular bandwidth saving. Test the setting and note whether the preview actually stops.
