the.com/instant replay

means A video playback of a sporting event's action, often slowed down, used to review what just happened or settle a disputed call.

from A 20th-century broadcasting term, born in American television — producers realized that recording live footage and replaying it seconds later could let viewers (and eventually officials) see a play again before the game had even moved on. 'Instant' marked the key innovation: unlike film replays of the past, which took time to develop, this replay happened almost immediately, changing how sports were watched and, later, officiated.
