9. A data output method for outputting multimedia data which includes at least one of video and audio, said data output method being executed in a device which includes an accumulation unit that accumulates the multimedia data, said data output method comprising:
-
a receiving step of receiving a signal from an external control device; a read-out step of reading out data from the accumulation unit; an output step of outputting the multimedia data to a designated output destination; and a control step of generating resume position information which indicates a position for resuming the multimedia data, obtained from the multimedia data for which the output is paused and a position at which the output is paused, and causing the generated resume position information to be stored in a storage unit, when a pause request which is a request to pause output in said output step is received in said receiving step, and reading out the resume position information from the storage unit, causing the multimedia data to be read out in said read-out step from the accumulation unit starting from the resume position shown by the resume position information; and
causing the read-out multimedia data to be outputted to the output destination when a resume request, which is a resume request for resuming the output in said output step, and an output destination are received in said receiving step.
