摘要

Provided is an operation control device (100) for controlling the execution of an operation related to audio data and/or video data, wherein a detector (116) detects an instruction for switching an operation to be executed. An operation controller (111) is capable of accessing a first holding unit for holding the state of progress of a first operation, and a second holding unit for holding the state of process of a second operation. The operation controller (111) stops execution of the first operation when a switch instruction is detected by the detector (116) during execution of the first operation, and holds the state of progress of the first operation in the first holding unit (113). The operation controller (111) starts execution of the second operation on the basis of the state of progress of the second operation acquired from the second holding unit (114).
