| 20080235390 | Moving Image Displaying Method and System - In order to overcome a difficulty in which, when a moving image played back by an operated-side computer is displayed on an operating-side computer through a network, a smooth moving image cannot be displayed because of being adversely influenced by the variation of a transfer data amount or a network bandwidth, a moving image displaying method and system are arranged to capture moving image playback event information being remotely operated and convey the information about the playback of the moving image on the operated-side computer to the operating-side computer. The operating-side computer provides a function of obtaining and receiving the moving image data played back on the event information, playing back the display image from the obtained moving image data, and overlapping the display image with the remote operation view. | 09-25-2008 |
| 20080263605 | VIDEO DELIVERY DEVICE, VIDEO RECEIVER AND KEY FRAME DELIVERY METHOD - In this video delivery device including: a storage device storing key frame information including a key frame number included in a contents file and offset from the beginning of a file; and a delivery control unit, which executes delivery in a predetermined cycle, the delivery control unit refers to the key frame information cycle by cycle in executing the trick play, and transmits the key frame having the offset closest to the delivery time among the key frames included in the contents file. | 10-23-2008 |
| 20090063778 | Storage System and Storage System Control Method - A storage system of the present invention improves the response performance of sequential access to data, the data arrangement of which is expected to be sequential. Data to be transmitted via streaming delivery is stored in a storage section. A host sends data read out from the storage section to respective user machines. A prefetch section reads out from the storage section ahead of time the data to be read out by the host, and stores it in a cache memory. A fragmentation detector detects the extent of fragmentation of the data arrangement in accordance with the cache hit rate. The greater the extent of the fragmentation, the smaller the prefetch quantity calculated by a prefetch quantity calculator. A prefetch operation controller halts a prefetch operation when the extent of data arrangement fragmentation is great, and restarts a prefetch operation when the extent of fragmentation decreases. | 03-05-2009 |
| 20090119697 | DISTRIBUTION DEVICE, DISTRIBUTION SYSTEM, AND DISTRIBUTION METHOD - A video distribution device that has a distribution judgment reference input function and a distribution judgment function, and can set different viewing limitations for different motion picture titles. Viewing limitations set viewable scenes and unviewable scenes in one motion picture title. Since the range of viewing limitations can be dynamically generated from access history, the motion pictures can be used for promotion, such as automatically extracting popular scenes for limited release. A viewing limitation range is reasonably decided based on more information by an interface for acquiring information such as access history from the outside. Furthermore, by embedding information of a link to another site in motion picture fragments limitedly released, viewers of the motion picture fragments can be guided to another site in which the whole motion picture can be viewed. | 05-07-2009 |
| 20090210700 | COMPUTER SYSTEM FOR JUDGING WHETHER TO PERMIT USE OF DATA BASED ON LOCATION OF TERMINAL - There is provided a computer system comprising a storage system, a terminal, a management server and the terminal, and a positioning module for identifying a location of the terminal. The terminal identifies the location of the terminal by the positioning module in a case of using the data, transmits terminal information including the identified location of the terminal to the management server; and transmits a usage request for the data to the management server. The management server judges whether or not use of the data is to be permitted based on the terminal information, and transmits permit information including usage conditions for the data to the terminal in a case where the use of the data is to be permitted. The terminal selects at least one of the volatile storage area and the nonvolatile storage area based on the usage conditions, and stores the copy of the data therein. | 08-20-2009 |
| 20110082950 | COMPUTER SYSTEM AND COMPUTER SYSTEM INPUT/OUTPUT METHOD - Under the environment where a storage system is virtualized by Thin Provisioning technology or the like, it is difficult to statically estimate the I/O characteristics of the entire virtual volume, causing a problem that the effect of input/output control by a computer cannot be fully achieved by I/O scheduling that is based on the characteristics of a virtual volume unit. To solve the above problem, the computer system of the present invention acquires characteristics information of a storage apparatus in which there exists an actual storage area corresponding to a virtual volume storage area that is the access target when accessing the virtual volume, divides an I/O request with respect to the virtual volume by storage apparatus in a case where the I/O request spans multiple storage apparatuses, carries out I/O scheduling based on the acquired actual area characteristics information, and issues the I/O request directly to the storage apparatus in accordance with the I/O scheduling result. | 04-07-2011 |
| 20110179247 | STORAGE SYSTEM AND UTILIZATION MANAGEMENT METHOD FOR STORAGE SYSTEM - A storage system | 07-21-2011 |
| 20110208910 | Storage Control Device for Storage System Provided with Storage Device Coupled to Switch Network - A plurality of storage devices are coupled with at least two switch of a switch network that is configured by a plurality of switches that transfer a packet that complies with an IP (Internet Protocol). Moreover, a storage control device is coupled with the switch network. The storage control device builds an LU (Logical Unit) that is utilized by a host device based on at least two storage devices that are coupled with different switches. | 08-25-2011 |
