The TimeRanges
interface is used to represent a set of time ranges, primarily for the purpose of tracking which portions of media have been buffered when loading it for use by the {{ HTMLElement("audio") }} and {{ HTMLElement("video") }} elements.
A TimeRanges
object includes one or more ranges of time, each specified by a starting and ending time offset. You reference each time range by using the start()
and end()
methods, passing the index number of the time range you want to retrieve.
The term "normalized TimeRanges object" indicates that ranges in such an object are ordered, don't overlap, aren't empty, and don't touch (adjacent ranges are folded into one bigger range).
