Patent number: 8726262Abstract: The present invention provides a firmware update process capable of realizing both recovery from an interruption of update and saving of a capacity of nonvolatile memory used for backup and storing difference data. Thus, intermediate data is included for always holding a status of firmware in rewriting in addition to the new and old firmware. In a case of updating all blocks configuring the firmware in an arbitrary order, the process successively compares blocks of the intermediate data and new firmware with each other; calculates an address of data for recovery from an interruption of update and a backup capacity required therefor; extracts difference data to be distributed, calculates a capacity thereof and creates an update procedure; and derives a processing order whose total of the backup capacity and the difference data capacity is the minimum (see FIG. 2).Type: GrantFiled: August 18, 2010Date of Patent: May 13, 2014Assignee: Hitachi Solutions, Ltd.Inventor: Nobuyuki Ohama

Patent number: 8522233Abstract: The present invention provides a firmware update technique in which a work area is small, a work time is short, update can be resumed even if power-down occurs, and even a file system which does not support writing is supported. To provide the firmware updating technique, an update creating and distributing server divides old and new version firmware images, extracts a difference between the new and old divided firmware images, creates an updated package, and delivers the updated package to an embedded device. On the other hand, the embedded device applies the updated package to the old version divided firmware image (an existing firmware message currently in use).Type: GrantFiled: March 8, 2010Date of Patent: August 27, 2013Assignee: Hitachi Solutions, Ltd.Inventors: Yuichi Nakamura, Nobuyuki Ohama

Publication number: 20130204969Abstract: Each of a dynamic image delivering server A 132 and a dynamic image delivering server B 133 delivers a plurality of contents list data and a dynamic image designated by each contents list data. A transcoding server 131 acquires prescribed contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, and stores them in a storage device. Then, the transcoding server 131 acquires the dynamic image designated by the acquired contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, converts the acquired dynamic image to a format of the dynamic image regenerable on a player 111, and stores the converted dynamic image in the storage device. Upon request from the player 111, the transcoding server 131 retrieves a contents list data and/or a dynamic image from the storage device, and transmits them to the player 111.Type: ApplicationFiled: August 27, 2010Publication date: August 8, 2013Applicant: HITACHI SOLUTIONS, LTD.Inventors: Shinya Nobuoka, Yuichi Nakamura, Nobuyuki Ohama

Publication number: 20110282966Abstract: A renderer (DMR) in a second local area network via an Internet is enabled to reproduce content in a first local area network. A content transmission system generates a virtual DMR corresponding to a DMR (content reproduction device) in a content reception system. A DMC (controller) and a DMS (content server) recognize the virtual DMR as if to be an actual DMR and communicate therewith. This enables content to be reproduced in an actual DMR in a different home network residing beyond the Internet without any modification on the DLNA standard. A transmission gateway device (transmission mechanism) relays communication destined for the virtual DMR (instructions and content) to a reception gateway device (reception mechanism). Also in the content reception system, the actual DMR is capable of processing communication from a different home network by communication only with the reception mechanism. This negates the need for modification on the DLNA standard.Type: ApplicationFiled: February 25, 2011Publication date: November 17, 2011Applicant: HITACHI SOLUTIONS, LTD.Inventors: Makiko OGAWA, Yuichi NAKAMURA, Shinya NOBUOKA, Makoto SHIINA, Nobuyuki OHAMA

Publication number: 20100153716Abstract: In a system to realize prevention of leakage and loss of confidential information by inhibiting writing into a secondary storage device or writing into external storage media, created confidential data is archived by a secure method without being lost if communication is not available and a file server cannot save the information. For this purpose, first, a designated folder is created on a non-volatile storing memory being built in a mobile terminal and created confidential data is saved in the folder. Then, a filter driver controls access to the designated folder to prevent leakage of information by an application in a mobile phone by a malicious user. Further, a function to remove data in the designated folder in the mobile terminal from a mobile terminal management server through a telephone network prevents loss of saved confidential data due to loss of the mobile terminal.Type: ApplicationFiled: October 10, 2007Publication date: June 17, 2010Inventors: Yasuhiro Kirihata, Nobuyuki Ohama
