Abstract: Computer-readable media having corresponding apparatus embodies instructions executable by a computer to perform a method comprising: receiving, from a user interface, an annotation associated with a background image; adding the annotation to a queue of pending annotations; causing transmission of the annotation to a server; removing the annotation from the queue of pending annotations, and adding the annotation to a list of acknowledged annotations, when an acknowledgment of the annotation is received from the server; and generating a display image comprising the background image, annotations in the list of acknowledged annotations, and annotations in the queue of pending annotations.

Abstract: Apparatus having corresponding methods and computer-readable media comprise a first input circuit to receive first data describing a first region of an image, the first region identified based on user markups of the image; a second input circuit to receive second data describing at least one of a second region of the image, the second region identified by an analysis of the image, and a third region of the image, the third region identified by an analysis of an environment that produced the image; and a synthesizer to identify a fourth region of the image based on the first data and the second data.

Abstract: A method for a communication system comprising a plurality of communication modules passing an audio stream comprising frames of audio data comprises receiving the audio stream at one of the communication modules; selecting one of the frames; identifying second data; replacing a portion of the audio data in the one of the frames with the second data; and transmitting the audio stream comprising the one of the frames of audio data comprising the second data from the one of the communication modules in the communication system.
