  • Publication number: 20150208000
    Abstract: An embodiment of the invention relates to a method comprising receiving media content from at least one recording device, wherein at least one media content received from said at least one recording device is complemented with personating data and creating remixed media content of the media content being received with said at least one personating data. In addition an embodiment of the invention relates to a method comprising capturing media content by a recording device; monitoring the capture of the media content by logging personating data to the recording device and transmitting at least part of the captured media content to a server, which at least part of the captured media is complemented with the personating data. Embodiments of the present invention also relates to a technical equipment for executing the methods.
