Information processing apparatus, image capturing apparatus, and control methods for the same

摘要

The information processing apparatus which plays video sent from a image capturing apparatus, comprises a list requesting unit which sends a request for segment list to the image capturing apparatus to acquire the segment list, a determination unit that determines a segment to be requested among the segments indicated in the acquired segment list, a first segment requesting unit that sends a request for the determined segment to the image capturing apparatus, a first segment acquisition unit that acquires the requested segment, and a playing unit that plays the acquired segment, wherein the list requesting unit sends a request for a latest segment list to the image capturing apparatus, whenever the segment is acquired a predetermined number of times by the first segment acquisition unit, and the determination unit determines a segment to be requested, based on the latest segment list.

主权项

1. An information processing apparatus that has a communication unit for communicating with an image capturing apparatus and plays video data captured by the image capturing apparatus by sequentially acquiring segments, which are each a portion of the video data, said apparatus comprising:
a list requesting unit that sends, to the image capturing apparatus via the communication unit, a request for a segment list, where the segment list includes segment information indicating at least one segment which the image capturing apparatus has not yet sent to the information processing apparatus among segments of video data that is being captured by the image capturing apparatus; a list acquisition unit that acquires, from the image capturing apparatus, the segment list requested by the segment list requesting unit; a first determination unit that determines a latest segment, as a live image to be played, among the segments indicated in the segment list acquired by the list acquisition unit; a first segment requesting unit that sends a request for the segment determined by the first determination unit to the image capturing apparatus via the communication unit; a first segment acquisition unit that acquires the segment requested by the first segment requesting unit; and a playing unit that plays, as the live image, the segment acquired by the first segment acquisition unit; wherein the list requesting unit sends a request for a latest segment list to the image capturing apparatus, whenever the segment is acquired by the first segment acquisition unit.
