Abstract: A module handles beams having multiple channels in an optical network. The module has a dispersion element, a liquid crystal (LC) based switching assembly, and photodetectors. The dispersion element is arranged in optical communication with the beams from inputs and is configured to disperse the beams into the channels across a dispersion direction. The switching assembly is arranged in optical communication with the channels from the dispersion element and is configured to selectively reflect the channels using electrically switchable cells of one or more LC-based switching engines. The photodetectors are arranged in optical communication with the dispersion element, and each are configured to receive selectively reflected channels for optical channel monitoring. Outputs can be arranged in optical communication with the dispersion element and can be configured to receive selectively reflected channels for wavelength selective switching.

Abstract: Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server.
