The processor can detect streams of media samples at the input ports and determine, in response to the detection of the streams of media samples, a capture start time. The processor can also capture a first frame of a first stream of media samples beginning at the capture start time, and a first frame of a second stream of media samples beginning at a first time subsequent to the capture start time. The processor can also calculate a relative offset time based on the capture start time, the first time, and a rate associated with the second stream of media samples, and store, in the memory, an indication of an association between the captured first frame of the second stream of media samples and the relative offset time.
