Abstract: An acoustic signal cancellation system is configured to perform: (a) provide a user device, associated with the system, and an audio capture device. (b) receive at system a captured signal indicative of a captured acoustic signal. It's received at capture device, and comprises a second acoustic signal generated by a second device, external to user device. (c) receive, from external source, a reference signal, indicative of a content included in the second signal. (d) in a case that a content of reference signal and the content in second signal are not time-synchronized, generate a synchronized reference signal, based on reference signal. Content of synchronized reference signal and second signal content are time-synchronized. (e) perform acoustic signal cancelling of that portion of captured signal which corresponds to second signal, based on reference signal. Generate reduced signal. This facilitates output of reduced signal to third device.

Abstract: A computerized method that may include (i) receiving, by one or more slicers, multiple input streams, the multiple input streams comprise (a) an input video stream that comprises visual information obtained from an event, and (b) at least one additional stream related to the event; (ii) converting the multiple input streams to a group of EISCVSs, different input streams are mapped to different EISCVSs; (iii) determining, by one or more personalization entities, a content to be sent to one or more user devices; (iv) generating, by the one or more personalization entities and based on the determining, the at least one personalized content stream to be sent to one or more user devices; and (v) sending the at least one personalized content stream to the one or more user devices.

Abstract: A computerized method for transmitting one or more video streams, the method may include receiving at least one input video stream that comprises visual information obtained from multiple fields of view that differ from each other; converting the at least one input video stream to a group of encoded independent self-contained video streams (EISCVSs), by performing a codec-agnostic process; wherein different EISCVSs comprise visual information from different spatial segments of the at least one input video stream; receiving a first request to receive video information related to a first direction related to a first user; generating a first video stream that comprises a first sub-set of EISCVSs that is related to the first direction; and sending the first video stream to a device of the first user, over a first communication link that has a first bandwidth that is lower than a bandwidth required to convey the input video stream.
