Abstract: Methods and computer-readable mediums are provided. For example, in one method a request is initiated for a security event update. Thereafter, a last received event identification (“LREI”) for at least one event type is retrieved from memory and inserted a security event update request. The request is transmitted as a polling signal towards a device (e.g., a server or remote client). In another method, a request signal containing is received. An LREI for an event type is extracted from the request. The LREI is compared to an event identification stored in memory. The results are inserted into a response. An indication, is inserted into the response, that at least one event identification is greater than said LREI and is not inserted in the response. The response is transmitted. In yet other embodiments, the computer-readable mediums and systems are also provided which perform similar features recited by the above methods.

Abstract: A method for temporal decomposition and reconstruction of an input video signal is disclosed. The method uses a prediction process and an update process in the framework of motion compensated temporal filtering (MCTF), the motion information used for the update process being derived from the motion information used for the prediction process, and the method employing a block based video codec composed of an encoder and a decoder. In response to the update and prediction processes on a picture being based on N reference pictures where N is greater than one, the update process is split into N update processes using a single picture as a reference. Each one of the split update processes is executed each time a picture that is needed as a reference by the process is received.
