Abstract: A method for timely transmission of first payload of data from sender device to receiver device includes obtaining a first payload of data to be transmitted; slicing at sender device, first payload of data to at least to first fragment of data appended by first fragment metadata jointly forming first fragment of first fragment size, and to second fragment of data appended by second fragment metadata jointly forming second fragment of second fragment size; transmitting, at least first fragment over first communication channel and at least second fragment over second communication channel; receiving, at least first fragment and at least second fragment at receiver device; and reconstructing, at receiver device, first payload of data from at least first fragment using first fragment metadata and first fragment of data or from at least second fragment using the second fragment metadata and the second fragment of data.

Abstract: A method for aligning manipulations in time and space to first model of three-dimensional (3D) real-world object in second model of 3D real-world environment said method includes: generating, by first terminal device, third model based on first model and second model, from first point of view; transmitting third model and timing metadata to second terminal device(s); receiving third model and timing metadata at second terminal device(s); manipulating third model by second terminal device(s); creating manipulation information; transmitting manipulation information from second terminal device(s) to first terminal device; receiving manipulation information at first terminal device; updating, by first terminal device, first model and second model from second point of view; and aligning, by first terminal device, manipulation information in time and space.
