Publication number: 20140328154Abstract: Crosstalk can be suppressed in photonic switching fabrics by activating unused photonic elements in a manner that manipulates the inactive connections and inhibits the propagation of cross-talk over the switching fabric. For example, unused photonic elements can be set to a cross or bar configuration to block first and second order crosstalk from propagating to the output ports, thereby reducing noise in the output signals. All of the unused elements can be activated in order to maximize crosstalk suppression. Alternatively, fewer than all of the unused elements may be activated to achieve a balance between crosstalk suppression and power conservation. Photonic switch architectures can be configured to use pre-determined cross-talk suppression maps (e.g., patterns of activated unused cells) for the various switching configurations, which may be computed using a recursive algorithm.Type: ApplicationFiled: September 4, 2013Publication date: November 6, 2014Inventors: Hamid Mehrvar, Yi Qian, Patrick Dumais, Dominic Goodwill, Eric Bernier

Patent number: 8656445Abstract: The present invention allows Internet Protocol television (IPTV) services to be provided to different types of subscriber devices over different types of networks via a multimedia subsystem, such as an IP multimedia subsystem. A given subscriber may have one subscription supporting IPTV services to different types of subscriber devices. Each of the subscriber devices may register with a given IPTV application server, which will interact with the various subscriber devices using a common session control protocol, such as the Session Initiation Protocol (SIP). The IPTV sessions may support delivery of various types of streaming content, such as audio or video content, for broadcast or on-demand services. Different IPTV sessions are used to support broadcast and on-demand services. However, within a given broadcast or on-demand IPTV session, channels may be changed or the streaming media may be controlled within the respective IPTV sessions.Type: GrantFiled: November 27, 2006Date of Patent: February 18, 2014Assignee: Genband US LLCInventors: David P.

Patent number: 8645990Abstract: Subscribers request programs from a network based content server and view the requested programs via their customer equipment. The content server receives various programs and breaks the program content for each program into a sequence of program segments, which are logically linked by program association indicia. The content server also receives advertisements and stores the advertisements as advertising segments, which generally contain at least one complete advertisement, but the invention is not limited thereto. Upon receiving a program request from a subscriber, the content server will identify advertising segments to provide along with the program segments for the requested program, and where to place the advertising segments among the program segments.Type: GrantFiled: December 22, 2006Date of Patent: February 4, 2014Assignee: Ciena CorporationInventors: Martin Jan Soukup, Dominic Goodwill, Martin Meier
