Claim 2:
3. The system control apparatus according to claim 1,
wherein the estimation unit
determines that the prototype manifest file acquired at the current acquisition timing and the prototype manifest file acquired at the previous acquisition timing are the same, is configured to:
acquire a value corresponding to a maximum value of a time length of segments as a first value, and determines a timing of a time when the first value elapses from the previous acquisition timing as a first acquisition timing candidate,
calculate a second value that is a statistical value for a time length of all or some segments of all segments in the prototype manifest file acquired, and determine a timing of a time when the second value elapses from the current acquisition timing as a second acquisition timing candidate, and
compare the first acquisition timing candidate and the second acquisition timing candidate to determine an acquisition timing candidate earlier in time as the next acquisition timing.
