Patent number: 9986519Abstract: A circuit includes a processor to store a beacon timestamp generated from a wireless network. An output port controlled by the processor causes an interrupt that initiates a capture of a link layer timestamp relative to the beacon timestamp. An input port on the processor receives the link layer time stamp. A synchronizer captures a processor timestamp relative to the beacon timestamp and determines a time offset value relative to the received link layer time stamp by computing a difference between the processor timestamp and the link layer timestamp. The time offset value is combined with the processor timestamp to synchronize the processor with respect to the beacon timestamp.Type: GrantFiled: June 30, 2015Date of Patent: May 29, 2018Assignee: Texas Instruments IncorporatedInventors: Oren Shani, Guy Mishol, Uri Weinrib

Patent number: 9877265Abstract: A coding approach for a robust and flexible network communication protocol is described. By using coding, it is possible to eliminate the need to track packet identities, and hence, it is possible to reduce coordination overhead associated with many conventional protocols. The method and system described herein takes advantage of multiple paths, interfaces, mediums, servers, and storage locations available in a network. The proposed protocol allows quick response to congestion by load balancing over different network resources. The method also enables soft vertical hand-overs across heterogeneous networks. In one embodiment, a media file is divided into chunks and transmitted using a transport protocol tailored to meet delay requirements of media streaming applications. Also described are different coding strategies for chunk delivery based upon an urgency level of each chunk.Type: GrantFiled: June 5, 2014Date of Patent: January 23, 2018Assignee: Massachusetts Institute of TechnologyInventors: Minji Kim, Muriel Medard, Ali Parandehgheibi
