Patent number: 10257240Abstract: In an embodiment, a method for calculating a noise index value for a digital audio source in a server computer system that is coupled to a plurality of audio sources and configured to operate a teleconference among the plurality of digital audio sources comprises receiving a first digital audio signal from the digital audio source of the one or more digital sources. Using the server computer system, the process identifies two or more types of sounds that are represented in the first digital audio source. The types of sounds identified include at least two of: one or more human voices; a background noise; or an actionable sound that mandates further action. Using a server computer system, calculating the noise index value based upon the types of sounds identified from the first digital audio signal.Type: GrantFiled: November 18, 2014Date of Patent: April 9, 2019Assignee: CISCO TECHNOLOGY, INC.Inventors: Hua Ouyang, Huahua Yin, Qi Shi, Yunwei Luo

Patent number: 10129313Abstract: An example method is provided and includes receiving an input associated with sharing data in a virtual meeting involving a first endpoint and a second endpoint associated with a meeting in a network environment. A window associated with an application that is running on the endpoint is scanned to determine a dataset for sharing, via the virtual meeting, with the second endpoint. The method also includes identify a portion of the dataset to restrict based on analyzing the dataset against a metric. The method also includes preventing a window of the at least one window from being transmitted, via the virtual meeting, to the second endpoint based on a determination that the window includes the portion of the dataset to restrict.Type: GrantFiled: February 10, 2015Date of Patent: November 13, 2018Assignee: Cisco Technology, Inc.Inventors: Hua Ouyang, Qi Shi, Huahua Yin, Yunwei Luo

Patent number: 10044979Abstract: Presented herein are techniques to enable a meeting participant/attendee at a first endpoint device in an online/web-based meeting/conference to acquire shared content with high resolution. The first endpoint device receives an initial image of content shared by a second endpoint in the online/web-based meeting/conference. At the first endpoint, the initial image of the shared content is displayed. A user selection of a selected region of the initial image is received at the first endpoint, and a second image of the shared content corresponding to the selected region is received at the first endpoint, wherein the second image has a higher resolution than the initial image.Type: GrantFiled: August 19, 2013Date of Patent: August 7, 2018Assignee: Cisco Technology, Inc.Inventors: Hua Ouyang, Qi Shi, Huahua Yin, Yi Lu, Yunwei Luo

Patent number: 9813461Abstract: An attendee device in an online conference session views a shared application window in a full screen mode. The attendee device receives data for content being shared by a host device, including at least one application window at a first resolution. The attendee device receives an input to enter a full screen mode for one of the application windows and determines whether displaying that application window at a second resolution for the full screen mode requires the image data to be magnified. When displaying the application window at the second resolution requires magnified image data, the attendee device requests the magnified image data from the meeting server facilitating the conference session. The meeting server provides the magnified image data to the attendee device, and the attendee device displays the application window in full screen mode using the magnified image data.Type: GrantFiled: November 19, 2013Date of Patent: November 7, 2017Assignee: Cisco Technology, Inc.Inventors: Hua Ouyang, Yi Lu, Qi Shi, Huahua Yin, Yunwei Luo

Patent number: 9544343Abstract: Techniques are presented herein to enable a first device participating in a conference session to adapt its displayed content being shared from a second device that has a larger display and can therefore display a larger area of content than the first device is capable of displaying. The first device has a first display and displays a portion of content being displayed on a second display of the second device that is being shared with the first device during an online conference session. The first device detects when a first change has occurred in the content that is outside of the portion displayed on the first display. A graphical element is displayed on the first display, the graphical element indicating that the first change has occurred in the content outside of the portion being displayed on the first device.Type: GrantFiled: July 3, 2013Date of Patent: January 10, 2017Assignee: Cisco Technology, Inc.Inventors: Hua Ouyang, Yi Lu, Huahua Yin, Qi Shi, Yunwei Luo
