Abstract: Disclosed is a scheme of transmitting at least two or more transmission signals, in which at least two or more pure random noise signals are contained, through multiple paths, according to one embodiment of the present invention. To implement such a scheme, a complementary noise generator may be used in a high-speed communication method and system with enhanced security according to the present invention. Here, the complementary noise generator refers to an apparatus in which a total sum of summing altogether at least two or more generated noises becomes 0. Namely, the complementary noise generator can generate m noises, and the sum of the in noises becomes 0. By injecting a plurality of noises having such feature into different paths, a channel capacity of each channel is reduced, thereby making a single wiretapping difficult.

Abstract: A method of generating a secondary video recording containing all interesting or notable moments of a particular event created simultaneously with a main video recording of the particular event. The method of generating a secondary video recording accomplishes this by receiving and identifying a user input as a means of identifying an interesting or notable moment. After identifying the user input an interval of the main video recording is calculated spanning the moments immediately prior and immediately following the instance when the user input was received. The method then stores the interval in a tempfile and continuously aggregates additional intervals within the same tempfile. Upon the conclusion of the main video recording, the method converts the tempfile into a secondary video recording containing the plurality of interesting and notable moments arranged in chronological order.
