Apparatus and method for synchronizing data in connected devices

摘要

A network-connectable terminal can synchronize data in connected devices. The network-connectable terminal includes a memory unit and a synchronization unit. The memory unit stores metadata updated according to update of data. The synchronization unit updates the metadata, creates version information indicating whether the metadata are updated, and exchanges version information with peripheral devices to determine a peripheral device and data requiring synchronization.

主权项

1. An apparatus capable of synchronizing data in a connected device, the apparatus comprising:
a memory unit configured to store metadata updated according to a data update; a communication unit configured to transmit and receive version information to and from peripheral devices, wherein the version information indicates whether the metadata are updated; and a synchronization unit configured to update the metadata, create the version information of the connected device, and receive the version information of the peripheral devices to determine data requiring synchronization, wherein the synchronization unit is further configured to:
receive, from a first device among the peripheral devices, version information of the first device in response to a connection with the first device, andtransmit the version information of the first device to a second device among the peripheral devices in response to a further connection with the second device, wherein the second device is configured to receive the version information of the first device without connecting with the first device.
