A computer-implemented method overlays an alert over a pre-recorded video regarding an upcoming segment of the pre-recorded video. One or more processors receive a pre-recorded video that is directed to a main topic, and then partition the pre-recorded video into sub-topic segments, where each sub-topic segment is about a sub-topic of the main topic. The processor(s) identify previous entities' responses while previous entities viewed precursory sub-topic segments from the pre-recorded video, where the precursory sub-topic segments were presented before an upcoming sub-topic segment. The processor(s) receive a current entity's responses that occurred while a current entity viewed one or more of the precursory sub-topic segments from the pre-recorded video, then compare the current entity's responses to the previous entities' responses. In response to the responses matching, the processor(s) overlay an alert over the pre-recorded video advising the current entity that the upcoming sub-topic segment will be difficult to understand.

An apparatus according to one approach includes a module having an array of transducers having at least two transducers. The apparatus also includes a persistent memory having stored therein data of a span of the array of transducers at a particular temperature. An apparatus according to another approach includes a module having fiducials at known positions relative to an array of transducers. The apparatus also includes a persistent memory having stored therein data of a span between the fiducials at a particular temperature. The fiducial span may be used in conjunction with the known locations of the fiducials relative to the array to characterize the span of the array.

A system executes a particular response for a particular sub-topic segment in a pre-recorded video. One or more processors receive a pre-recorded video, where the pre-recorded video is directed to a main topic, and then partition the pre-recorded video into multiple sub-topic segments, where each sub-topic segment is about a sub-topic of the main topic. The processor(s) identify previous entities' responses to sub-topic segments from the pre-recorded video. The processor(s) then compare a current entity's responses to the previous entities' responses that occurred while one or more precursory sub-topic segments are presented before a particular sub-topic segment in the pre-recorded video. In response to a match, the particular response is executed on behalf of the current entity in response to the one or more precursory sub-topic segments being presented to the current entity.

A show system or in-room entertainment or show system configured to provide engaging and immersive multimedia shows or presentations in nearly any space (or room) that is defined by one or more walls. The in-room show system generally includes a controller for selectively operating a display device (e.g., a television or the like), a video projector, an audio system (e.g., one or more speakers), and other show components (e.g., one or more lights, a fan, a mechanical device, and so on). Media content is predefined for the room, and the controller operates (such as in response to a triggering switch or remote control device that may take the form of a show prop activated by someone in the room) to serve the media content to tell a story and/or magically transform the space into a multidimensional and immersive entertainment space.
