Publication number: 20240134675Abstract: A display apparatus for vehicle is disclosed. The display apparatus includes a first display and a second display located in a vehicle, a signal processing device including a processor configured to perform signal processing for the first display and the second display, and a second signal processing device including a second processor configured to perform signal processing for a third display, wherein the processor in the signal processing device is configured to execute first to third virtual machines on a hypervisor in the processor, and, in response to the signal processing device being operated as a master signal processing device, the first virtual machine in the processor is configured to share at least some of data with the second signal processing device for divided processing of data. Consequently, the plurality of signal processing devices for the plurality of displays in the vehicle may divide and process data.Type: ApplicationFiled: August 12, 2021Publication date: April 25, 2024Inventors: Jaegu YOON, Yuseok YANG, Eunjin KIM, Daeyoung JEONG, Dongwoo HAN, Dongkyu LEE, Dukyung JUNG

Patent number: 7613303Abstract: Controlling delivery of broadcast encryption content for a network cluster from a content server outside the cluster that include receiving in the content server from the network device a key management block for the cluster, a unique data token for the cluster, and an encrypted cluster id and calculating a binding key for the cluster in dependence upon the key management block for the cluster, the unique data token for the cluster, and the encrypted cluster id. In typical embodiments, calculating a binding key includes calculating a management key from the key management block for the cluster; calculating a content server device key from the management key and the content server device id; decrypting the encrypted cluster id with the content server device key; and calculating the binding key with the management key, the unique data token for the cluster, and the cluster id.Type: GrantFiled: June 30, 2008Date of Patent: November 3, 2009Assignee: International Business Machines CorporationInventors: Eunjin Jung, Amal Ahmed Shaheen

Publication number: 20090013179Abstract: Methods, systems, and products are disclosed for delivering broadcast encryption content. Embodiments of the present invention typically include receiving in a cluster broadcast encryption content; receiving in a cluster a rights object defining device-oriented digital rights for broadcast encryption content; and administering the broadcast encryption content on one or more network devices in the cluster in dependence upon the digital rights. In some embodiments, administering the broadcast encryption content on one or more network devices in the cluster in dependence upon the digital rights include mapping the device-oriented digital rights to digital rights supported in the cluster, excluding device-oriented rights not supported in the cluster. In some embodiments, mapping the device-oriented digital rights to digital rights supported in the cluster includes supporting in the cluster only those device-oriented digital rights having direct analogs in the cluster.Type: ApplicationFiled: March 31, 2008Publication date: January 8, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eunjin Jung, Amal Ahmed Shaheen
