Patent number: 10110647Abstract: A method for altering bandwidth consumption when receiving content in a user device includes determining a first user device status where the first user device status indicates whether content, which is being accessed by a content-rendering application, is viewable on a display of the user device, based on the first user device status, selecting one of a plurality of available alternative content segments, and receiving the selected content segment.Type: GrantFiled: September 25, 2013Date of Patent: October 23, 2018Assignee: QUALCOMM IncorporatedInventors: Chandrasekar Srinivasan, Umesh Pandey, Chandra Mouli Polisetty, Deepti Mani, Lorenz C. Minder, Deviprasad Putchala, Arvind Subramanian Krishna

Patent number: 9948578Abstract: A device includes a de-jitter buffer configured to receive a packet, the packet including first data and second data. The first data includes a partial copy of first frame data corresponding to a first frame of a sequence of frames. The second data corresponds to a second frame of the sequence of frames. The device also includes an analyzer configured to, in response to receiving the packet, generate a first frame receive timestamp associated with the first data. The analyzer is also configured to, in response to receiving the packet, generate a second frame receive timestamp associated with the second data. The first frame receive timestamp indicates a first time that is earlier than a second time indicated by the second frame receive timestamp.Type: GrantFiled: August 18, 2015Date of Patent: April 17, 2018Assignee: QUALCOMM IncorporatedInventors: Subasingha Shaminda Subasingha, Vivek Rajendran, Duminda Dewasurendra, Chandra Mouli Polisetty, Venkatraman S. Atti, Venkata Subrahmanyam Chandra Sekhar Chebiyyam

Patent number: 9680507Abstract: A method includes determining, at a decoder of a first device, an offset value corresponding to an offset between a first particular packet and a second particular packet. The first device includes a de-jitter buffer. The method also includes transmitting the offset value to an encoder of a second device to enable the second device to send packets to the first device based on the offset value.Type: GrantFiled: June 24, 2015Date of Patent: June 13, 2017Assignee: QUALCOMM IncorporatedInventors: Subasingha Shaminda Subasingha, Venkatesh Krishnan, Vivek Rajendran, Venkatraman S.

Publication number: 20150074195Abstract: The disclosure relates to wireless communication performed by various user devices. A user device determines whether or not it is an active user device, transmits a notification to the one or more user devices indicating that it is not the active user device, and receives, from the active user device, updated application data for one or more applications installed on both the user device and the active user device, wherein a same user is logged in to the one or more applications on both the user device and the active user device. The active user device transmits a notification to the one or more user devices indicating that it is the active user device, receives, from a remote server, updated application data for the one or more applications, and transmits the updated application data to the one or more user devices.Type: ApplicationFiled: August 28, 2014Publication date: March 12, 2015Inventors: Deepti MANI, Chandra Mouli POLISETTY

Publication number: 20150045041Abstract: Multi-subscription access terminals are adapted to facilitate establishment of a transcoder-free communication path. According to at least one example, an access terminal can initiate a call with a terminating communication device using a first subscription, including attempting to establish a transcoder-free communication path. If a transcoder-free communication path cannot be established using the first subscription, the access terminal can switch to using a second subscription. The access terminal can then initiate a call with the terminating communication device using the second subscription module, including attempting again to establish a transcoder-free communication path.Type: ApplicationFiled: August 12, 2013Publication date: February 12, 2015Applicant: QUALCOMM IncorporatedInventors: Chandra Mouli POLISETTY, Deepti MANI

Patent number: 8780978Abstract: A video encoder may reduce bandwidth consumption by skipping encoding of or reducing an encoding rate of video frames corresponding to silent audio frames, that is, audio frames that do not include speech data. In one example, an apparatus includes a video encoder comprising a coding unit configured to encode video data in a first or second mode and a mode select unit configured to receive an indication of whether encoded audio data corresponding to the video data to be encoded includes speech data. When the audio data includes speech data, the mode select unit selects the first mode, and when the audio data does not include speech data, the mode select unit selects the second mode. The second mode consumes relatively less bandwidth, e.g., by reducing a bitrate, modifying a quantization parameter to increase quantization, and/or reducing a frame rate relative to the first mode.Type: GrantFiled: November 4, 2009Date of Patent: July 15, 2014Assignee: QUALCOMM IncorporatedInventors: Chandra Mouli Polisetty, Aditya Bhuvanagiri

Patent number: 8154450Abstract: A smart antenna system may exploit space diversity by employing an array of antennas whose radiation pattern can be aligned in a direction of arrival (DoA) of a specific signal to be decoded. Smart antennas can be installed on a base station side and/or on a user terminal side. Certain embodiments of the present disclosure provide methods for computationally efficient and accurate searching of the DoA of a specific transmitted signal. The proposed methods utilize Assisted Global Positioning System (A-GPS) coordinates to determine the DoA.Type: GrantFiled: June 5, 2009Date of Patent: April 10, 2012Assignee: QUALCOMM IncorporatedInventors: Chandra Mouli Polisetty, Venu Gopal Rao Mullu
