Abstract: A system is engineered to analyze, process, and manipulate streaming content in real time including analyzing, interacting with, and embedding streaming video images based on the content of the images or on collaborative interactions and information. Among many, many examples, one can create advertisements dynamically overlaid within live video based upon characteristics within the live video, as well as have the ability to interact with live video in a social network. Various other examples include, among others, advertising, security analysis, and live special effects. The system performs analytics of data as it is collected to determine features and patterns in the data and use the resulting analysis to alter the streaming content as it occurs.

Abstract: A method and apparatus is provided for presenting a design of a fiber-optic network. In one aspect, a server receives from a client device a request for a diagram of the design. The server accesses a data-structure representing the design, generates a representation of a cable run, and transmits the representation to the client device for display. In another aspect, the server transmits to the client device an indication that the cable run is illegal and receives from the client device an indication of a user-specified cable run. Subsequently, the server modifies the data structure to replace the illegal cable run with the user-specified cable run.
