Embodiments relate to methods and apparatuses () for synchronizing a first event (), having associated therewith a first original event timing value based on a common clock signal, and a second event (), having associated therewith a second original event timing value based on the common clock signal, wherein the first and the second event () experience different delays while travelling through different paths of a distributed computing system (), and wherein at least one output event () is to be determined by an event detector () based on the first and the second event (). The apparatus () comprises a delay compensator () associated to the event detector (), the delay compensator () having an input () for receiving the first and the second event () and having an output () for forwarding relayed versions (') of the received first and second event to the associated event detector (), wherein the delay compensator () is operable to relay the first and the second event () to the associated event detector () based on the experienced delays and based on the associated first and second original event timing values.

Embodiments relate to a concept for migrating an event detector of a first node (N) of a distributed computing system () to a second node (N) of the distributed computing system, wherein the event detector processes a plurality of input events (e; A, B, C) to generate at least one output event (D) based on the input events, wherein each of the input events has associated therewith an individual event delay corresponding to a propagation time of the input event to the first node (N). It comprises transferring (), from the first node (N) to the second node (N), information on event delays corresponding to the plurality of input events (e; A, B, C) at the first node (N); transferring () a content of the event detector from the first node (N) to the second node (N) to obtain a migrated event detector at the second node; forwarding () the plurality of input events (e; A, B, C) from the first node (N) to the second node (N); receiving (), at the second node (N), the plurality of input events (e; A, B, C) forwarded from the first node (N) and, in parallel, from originating event detectors associated to the plurality of input events; and processing (), at the second node (N), the plurality of received input events (e; A, B, C) based on the transferred information on the event delays and based on event delays of the plurality of input events (e; A, B, C) received from the associated originating event detectors.

Encoder for encoding data defining coded positions representing a trajectory of an object based on spatio-temporal data representing a time series of positions of the object. The encoder comprises a deriver, a selector, and a coder. The deriver is configured for deriving a plurality of components of a motion vector difference between a last coded motion coded vector pointing from a second last coded position to a last coded position and a current motion vector pointing from the last coded position to a current position of the object. The selector is configured for selecting a component of the plurality of components of the motion vector difference. The coder is configured for coding the current motion vector based on the selected component of the motion vector difference to obtain a current coded motion vector, thereby defining a current coded position.
