Storage apparatus and method, program, and playback apparatus and method

摘要

A storage apparatus and method, a program, and a playback apparatus and method, capable of quickly reading a specific part of data among metadata including metadata associated with faces. A storage controller controls storing face metadata in a storage medium, wherein the face metadata includes a content data set added for each content, content data storage location information indicating the storage location of the content data set, a detected face data set associated with each of face images detected from a content, and detected face data storage location information indicating the storage location of the detected face data set, and wherein the face metadata is configured such that the content data storage location information and face block storage location information indicating the storage location of the detected face data storage location information are described in a single data set. The present invention is applicable to a digital camera.
