Method and arrangement for transferring multimedia data

摘要

A method, arrangement and computer program for transferring multimedia data from a multimedia data capture device to a metadata recording device via a data communication connection and for enhancing the multimedia data using metadata captured by the recording device. The method involves establishing a data communication connection between the data capture device and a metadata recording device, determining the time difference between the clocks of the devices, receiving a captured multimedia data item from the multimedia data capture device. having a first timestamp indicating the creation time of the data item, recording metadata having a second timestamp indicating the creation time of the metadata according to the clock of the metadata recording device, and associating the captured multimedia data item with the metadata, utilizing the first and the second timestamps, where at least one timestamp is corrected using the time difference between the clocks of the two devices.

1. A method for transferring multimedia data from a multimedia data capture device to a metadata recording device via a data communication connection and for enhancing the multimedia data using metadata captured by the metadata recording device, the method comprising:
establishing a data communication connection between the multimedia data capture device and the metadata recording device, determining, during the data communication connection, a time difference between a clock of the multimedia data capture device and a clock of the metadata recording device, receiving, by the metadata recording device, at least one captured multimedia data item from the multimedia data capture device, the captured multimedia data item comprising multimedia data and a first timestamp indicating the creation time of the captured multimedia data item, the first timestamp being generated by the clock of the multimedia data capture device, recording, using the metadata recording device, metadata comprising a second timestamp indicating the creation time of the metadata and geographic location information of the metadata recording device, the second timestamp being generated by the clock of the metadata recording device, and associating, by the metadata recording device, the captured multimedia data item with the recorded metadata, wherein the association is utilizing the first and the second timestamps, of which timestamps at least one timestamp is corrected using the determined time difference between the clocks of the multimedia data capturing device and the metadata recording device.
