User interface for television channel surfing

A system comprising:

• input circuitry configured to receive a first video stream from a first video source;
• control circuitry configured to:
• generate, for display in a first video stream panel on a user interface configured for simultaneous display of multiple panels, the first video stream;
• determine, while generating for display the first video stream, that the first video stream comprises a non-skippable advertisement;
• command input circuitry configured to receive a command to view a second video stream from a second video source;
• and
• the control circuitry being further configured to:
• based at least in part on the determining that the non-skippable advertisement was being displayed in the first video stream when the command to view the second video stream was received:
• generate on the user interface an additional second video stream panel, such that the user interface simultaneously displays the first video stream panel and the second video stream panel;
• arrange the first video stream panel and the second video stream panel in a particular configuration;
• generate, for display in the second video stream panel, the second video stream;
• and
• lock the first video stream panel such that user interface requests to change the first video stream panel to display another video stream are disabled while the first video stream panel is locked at least for the duration of the non-skippable advertisement.
