TERMINAL DEVICE, SERVER DEVICE, DATA MANAGEMENT SYSTEM, AND RECORDING MEDIUM ON WHICH PROGRAM IS RECORDED

摘要

Some embodiments may include a transmitting unit which transmits, when one or more pieces of stored data each being an entity at storage of a digital asset are respectively stored in one or more data storage devices, identification data for uniquely identifying the digital asset to a server device; and a receiving unit which receives, from the server device, digital asset use feature information indicating a feature during use of the digital asset uniquely identified by the identification data transmitted by the transmitting unit, and digital asset entity information indicating an entitative feature of each of the one or more pieces of stored data each being an entity at storage of the digital asset uniquely identified by the identification data.

主权项

1. A terminal device, comprising:
a transmitting unit configured to transmit, when one or more pieces of stored data each being an entity at storage of a unique bitstream are respectively stored in different modes in one or more data storage devices, identification data for identifying all of the pieces of stored data capable of restoring the unique bitstream, to a server device; a receiving unit configured to receive, from the server device, bitstream use feature information indicating a feature during use of the unique bitstream indicated by the identification data transmitted by the transmitting unit, and stored data entity information indicating an entitative feature of each of the one or more pieces of stored data capable of restoring the unique bitstream indicated by the identification data; and a determining unit configured to, when the bitstream use feature information includes quality information during use of the bitstream, the stored data entity information includes data compression scheme information of the bitstream, and the quality information included in the bitstream use feature information received by the receiving unit is not within a prescribed range, determine that none of the stored data identified by the identification data is to be acquired at a point in time at which the quality information is determined not to be within the prescribed range, and when the quality information received by the receiving unit is within the prescribed range and the data compression scheme information included in the stored data entity information received by the receiving unit matches at least one piece of prescribed data compression scheme information, determine that stored data corresponding to the stored data entity information including the matching prescribed data compression scheme information is to be acquired from the data storage device.
