METHOD AND APPARATUS OF SHARING CONTENTS ASSETS VIA PICTURE TRANSFER PROTOCOL

摘要

A method and a device for sharing contents asset through a PTP(Picture Transfer Protocol) is provided to enable two devices to share the contents asset efficiently without changing the usual PTP and the specification for the contents asset, such as an MPV(Music/Photo/Video) album. A communicator(911) communicates with a first device(900), and a storing part(913) stores a file for controlling the contents asset and at least one object file included in the contents asset. A controller(912) corrects a contents asset control file and transfers the corrected contents asset control file to the first device by reading the contents asset control file from the storing part and recording an object ID corresponding to each object file to the contents asset control file additionally when a request for the contents asset control file is received from the first device through the communicator. The controller assigns the object ID to an MPV root album file corresponding to the contents asset when a PTP session is connected with the first device.
