A method and system for identification of a deviation from a periodic behavior pattern in a sequence of multimedia content segments are provided. The system comprises receiving the sequence of multimedia content segments; generating at least one signature for each multimedia content segment of the sequence of multimedia content segments; comparing at least two signatures generated for at least two consecutive multimedia content segments to detect a periodic behavior pattern; upon detecting the periodic behavior pattern, comparing at least one signature generated for at least a subsequently received multimedia content segment to at least one signature representing the detected multimedia content segment to identify a deviation from the periodic behavior pattern; and upon identifying the deviation from the periodic behavior pattern, generating a notification with respect to the at least one deviation.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for identification of a deviation from a periodic behavior pattern in a sequence of multimedia content segments, comprising: receiving the sequence of multimedia content segments; generating at least one signature for each multimedia content segment of the sequence of multimedia content segments; comparing at least two signatures generated for at least two consecutive multimedia content segments to detect a periodic behavior pattern; upon detecting the periodic behavior pattern, comparing at least one signature generated for at least a subsequently received multimedia content segment to at least one signature representing the detected multimedia content segment to identify a deviation from the periodic behavior pattern; and upon identifying the deviation from the periodic behavior pattern, generating a notification with respect to the at least one deviation. 2. The method of claim 1, wherein each multimedia content segment of the sequence of multimedia content segments is at least one of: an image, a graphic, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, and portions thereof. 3. The method of claim 1, wherein the periodic behavior pattern is related to at least one of: an object that appears in the sequence of multimedia content segments in regular time intervals, an event that occurs through the sequence of multimedia content segments in regular time intervals, and an activity that occurs through a number of consecutive segments in regular time intervals. 4. The method of claim 3, wherein the object, the event, and the activity are determined using a context of the received sequence of multimedia content segments. 5. The method of claim 1, wherein the periodic behavior pattern is detected upon identification of matching of signatures of a number of consecutive content segments exceeding a first threshold. 6. The method of claim 5, wherein at least two signatures match when the at least to signatures overlap more than a first preconfigured threshold level. 7. The method of claim 1, wherein the detection of the periodic behavior pattern further comprises: providing a baseline signature respective of the periodic behavior pattern. 8. The method of claim 7, wherein the detection of the deviation from the periodic behavior pattern further comprises: comparing the at least one signature generated for the at least a subsequently received multimedia content segment to the baseline signature; and detecting the deviation from the periodic behavior pattern when the at least one signature generated for the at least a subsequently received multimedia content segment and the baseline signature overlap less than a second preconfigured threshold level. 9. A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute the method according to claim 1. 10. A system for identification of a deviation from a periodic behavior pattern in a sequence of multimedia content segments, comprising: a processing system; a memory connected to the processing system, the memory contains instructions that when executed by the processing system, configure the system to: receive the sequence of multimedia content segments; generate at least one signature for each multimedia content segment of the sequence of multimedia content segments; compare at least two signatures generated for at least two consecutive multimedia content segments to detect a periodic behavior pattern; upon detecting the periodic behavior pattern, compare at least one signature generated for at least a subsequently received multimedia content segment to at least one signature representing the detected multimedia content segment to identify a deviation from the periodic behavior pattern; and upon identification of the deviation from the periodic behavior pattern, generate a notification with respect to the at least one deviation. 11. The system of claim 10, wherein each multimedia content segment of the sequence of multimedia content segments is at least one of: an image, a graphic, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, and portions thereof. 12. The system of claim 10, wherein the periodic behavior pattern is related to at least one of: an object that appears in the sequence of multimedia content segments in regular time intervals, an event that occurs through the sequence of multimedia content segments in regular time intervals, and an activity that occurs through a number of consecutive segments in regular time intervals. 13. The system of claim 12, wherein the object, the event, and the activity are determined using a context of the received sequence of multimedia content segments. 14. The system of claim 10, wherein the periodic behavior pattern is detected upon identification of matching of signatures of a number of consecutive content segments exceeding a first threshold. 15. The system of claim 14, wherein at least two signatures match when the at least to signatures overlap more than a first preconfigured threshold level. 16. The system of claim 10, wherein the system is further configured to: provide a baseline signature respective of the periodic behavior pattern. 17. The system of claim 16, wherein the system is further configured to: compare the at least one signature generated for the at least a subsequently received multimedia content segment to the baseline signature; and detect the deviation from the periodic behavior pattern when the at least one signature generated for the at least a subsequently received multimedia content segment and the baseline signature overlap less than a second preconfigured threshold level.
