Information processing method, information processing system, information processing apparatus, and program

摘要

An information processing method includes: grouping temporally consecutive data into a plurality of groups based on a reference defined in advance and storing the grouped data; reading, in response to an access request from an external apparatus, target data to be a target of the request from a first group including the target data and outputting the read target data to the external apparatus; and reading, in response to the reading of the target data, at least part of data from a second group different from the first group as read-ahead target data.

1. An information processing method, comprising:
grouping temporally consecutive data, which is a plurality of consecutive frame images, into a plurality of groups based on a reference defined in advance and storing the grouped data, wherein the plurality of groups each include at least one or more of the frame images, and wherein the grouping temporally consecutive data includes storing the plurality of frame images by a first storage unit configured to store the frame images and to have a first output capability for outputting the stored frame images and by a second storage unit configured to have a second output capability lower than the first output capability; reading, in response to an access request from an external apparatus, target data to be a target of the request from a first group including the target data, wherein the target data is a target frame image to be the target of the request, and outputting the read target data, including the target frame image stored on the first storage unit, to the external apparatus; and reading, in response to the reading of the target data, at least part of data from a second group different from the first group as read-ahead target data, which is at least one or more of the frame images included in the second group, wherein the reading at least part of data includes reading the read-ahead target frame image as the read-ahead target data from the second storage unit and causing the first storage unit to store the read-ahead target frame image.
