Publication number: 20240015208Abstract: Disclosed herein are a content provision method and apparatus using a convergence network. The content provision method may include creating a Quick UDP Internet Connections V1 (QUICV1) path with User Equipment (UE) through a Fifth-Generation (5G) core, when content satisfies a preset condition while the content is being provided to the UE through the QUICV1 path, determining to offload the content through the 5G core, creating an Internet Protocol Security (IPSEC) tunnel with an Advanced Television Systems Committee (ATSC) gateway (GW) through the 5G core, generating a QUIC multicast stream, providing QUIC multicast session information to multiple UE devices, and providing the content to multiple UE devices, for which a mode switches from a QUICV1 mode to a QUIC multicast mode, through the ATSC GW.Type: ApplicationFiled: March 22, 2023Publication date: January 11, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Hoi-Yoon JUNG, Sung-Ik PARK, Nam-Ho HUR, David Gomez-Barquero, Carlos Barjau Estevan

Patent number: 10454536Abstract: Disclosed herein are a method for transceiving a broadcast signal using a combination of multiple antenna schemes with layered division multiplexing and an apparatus for the method. A method for receiving a broadcast signal includes generating received signals based on signals that are received through multiple receiving antennas, estimating channels between the receiving antennas and transmitting antennas, restoring a core-layer signal corresponding to the received signals, and restoring an enhanced-layer signal based on a cancellation process, wherein the cancellation process corresponds to the core-layer signal and is separately performed for the individual receiving antennas.Type: GrantFiled: May 30, 2018Date of Patent: October 22, 2019Assignee: Electronics and Telecommunications Research InstituteInventors: Sung-Ik Park, Bo-Mi Lim, Sun-Hyoung Kwon, Heung-Mook Kim, Jae-Hyun Seo, Jae-Young Lee, Nam-Ho Hur, Hoi-Yoon Jung, David Gomez-Barquero, Eduardo Garro

Patent number: 9473174Abstract: An error correcting encoder includes an error correcting data generator for receiving payload data belonging to a first category, for receiving payload data belonging to a second category, for determining first error correcting data for the first category payload data, and for determining second error correcting data for the second category payload data. The error correcting encoder further includes an interleaver for interleaving at least the second error correcting data and the second category payload data with each other. A first interleaving length relative to an interleaving of the first error correcting data and the first category payload data differs from a second interleaving length relative to the interleaving of the second error correcting data and the second category payload data. A corresponding error correcting decoder and methods for error correcting encoding/decoding are also disclosed.Type: GrantFiled: May 15, 2014Date of Patent: October 18, 2016Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Cornelius Hellge, Thomas Schierl, Thomas Wiegand, David Gómez-Barquero
