Publication number: 20220335703Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to provide improved region of interest (ROI) tracking, image framing, and distortion correction for wide field of view (FOV) video image streams. The techniques disclosed may be configured, such that the image framing decisions made over the course of a captured wide FOV video image stream are able to be panned smoothly and seamlessly transition between framing a narrower portion of a wide angle camera's FOV to framing a wider portion of the wide angle camera's FOV (or vice versa), e.g., depending on the composition and movement of relevant subjects in the captured scene. The techniques disclosed herein may also be used to perform any distortion correction desired on the framed image portions in the output video image stream, e.g., based on the image portions' FOVs and/or the locations of the portions within the original wide FOV video image stream.Type: ApplicationFiled: March 25, 2022Publication date: October 20, 2022Inventors: Sudhakar Valluru, Ali-Amir Aldan, Brandon J. Corey, Siva Kiran V. Yellamraju

Patent number: 8838771Abstract: Providing fail_over call processing services by sniffing signaling traffic, without the overhead of configuring/provisioning terminals (phones), call servers etc. According to an aspect of the present invention, the integrated device operates as a backup call server when external call servers are unavailable. In one embodiment, the integrated device checks whether a first call server, to which a call setup request is destined to, is available, and forwards the request to another call server if the first call server is unavailable. According to another aspect, the integrated device detects the access information of each terminal registering with a call server, and uses the detected information to provide responses to call setup requests when the call servers are unavailable. As a result, the IP phones in a local network can continue initiating calls even when call servers located at remote sites, become unavailable.Type: GrantFiled: May 24, 2006Date of Patent: September 16, 2014Assignee: Alcatel LucentInventors: Parag Narayanrao Pote, Sudhakar Valluru, Ganesh Pai

Patent number: 8320383Abstract: The invention includes a method and apparatus providing call admission control for a wireless local area network (WLAN). A method includes extracting call signaling information from call signaling messages exchanged between a first user terminal and a second user terminal for establishing a voice call, where the second user terminal is being served by a wireless access point, and propagating a quality-of-service request toward the wireless access point which may be used by the wireless access point for determining whether or not to accept the voice call. The quality-of-service request includes at least one quality-of-service parameter determined using the extracted call signaling information. The at least one quality-of-service parameter is adapted for use by the wireless access point for determining whether or not to accept the voice call.Type: GrantFiled: October 31, 2007Date of Patent: November 27, 2012Assignee: Alcatel LucentInventor: Sudhakar Valluru

Patent number: 7499977Abstract: A method and system for fault management in a distributed network management station is disclosed. In one method embodiment, the present invention initiates a first device coupled to a network. Next, the present invention broadcasts an information packet to a plurality of devices coupled to the network. The first device then resolves the status of the plurality of devices coupled to the network. In so doing, the resolved network results in a distributed network management station having a defined master device.Type: GrantFiled: January 14, 2002Date of Patent: March 3, 2009Assignee: Cisco Technology, Inc.Inventors: Sudhakar Valluru, Srikumar Chari

Patent number: 7380164Abstract: An Integrated Communication System (ICS) with fail-over serial data connectivity is disclosed. In one aspect, an ICS may comprise a chassis including a System Switch Processor (SSP) for providing connectivity to a plurality of slots. A Serial Alarm Processor (SAP) may be operatively coupled to the ICS through one of the slots, an include at least one serial port for providing serial data connectivity. A Primary Single Board Computer (SBC) and at least one secondary SBC may be disposed in the slots. The ICS may be configured to pass control of serial data connectivity from the Primary SBC to a secondary SBC in the event of the failure of the Primary SBC. Various methods for fail-over serial data connectivity are also disclosed.Type: GrantFiled: March 3, 2006Date of Patent: May 27, 2008Assignee: Cisco Technology, Inc.Inventors: Lars Borresen, Sudhakar Valluru, William Davids

Publication number: 20070211868Abstract: Integrating proxy voice mail server (PVMS) and a switch/router into a single unit. According to another aspect, the PVMS downloads voice mail messages (related to users served in PVMS) when bandwidth utilization is below a pre-specified threshold. According to another aspect, previously recorded voice mail messages are uploaded to a central VMS (CVMS) also when the bandwidth utilization is below a pre-specified threshold. According to one more aspect, the voice mail messages stored locally in a PVMS are provided to a user (instead of from the CVMS) when the bandwidth utilization is above a threshold.Type: ApplicationFiled: March 12, 2006Publication date: September 13, 2007Applicant: NetDevices, Inc.Inventors: Seenu Banda, Sudhakar Valluru

Publication number: 20060251113Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station, the mobile station being operable to roam between a private and a public network. The mobile station is signaled via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits. One or more features associated with a private network are delivered to the mobile station during the communication session as an end user moves between the public and private networks.Type: ApplicationFiled: June 16, 2006Publication date: November 9, 2006Applicant: Cisco Technology, Inc.Inventors: Ramanathan Jagadeesan, Bich Nguyen, Kamaldip Toor, Sudhakar Valluru, Christopher Pearce

Publication number: 20050059402Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station. The request is responded to by signaling the mobile station via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established to accommodate voice data that may propagate between the communication device and the mobile station. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits such that one or more features associated with a private network are delivered to the mobile station during the communication session.Type: ApplicationFiled: September 11, 2003Publication date: March 17, 2005Inventors: Ramanathan Jagadeesan, Bich Nguyen, Kamaldip Toor, Troy Trenchard, Sudhakar Valluru, Tony Wan
