Publication number: 20140026173Abstract: In a video distribution apparatus, a memory caches segments of video data into which video data received from a communication network is sectioned on a basis of a predetermined unit and stores video identifying information of the segments of video data. A distribution controller derives, upon receipt of a cache distribution request from the network, video identifying information contained in a cache distribution request. A relay controller obtains segments of video data associated with the video identifying information from the memory to transfer the obtained segments of video data to a requester at a transfer rate defined on the segments of video data in the vicinity of a source of the video data.

Patent number: 8548677Abstract: A content management section rearranges contents in an order from a content having a greater information value, preparing a content list. With respect to assignable areas of a display apparatus, a region value is compared with an information value of each content; the content may be assigned to the area when the information value exceeds the region value. The contents are associated with information values and the areas are associated with region values; thus, the content can be assigned to the area that is more suitable. When there are several assignable areas, a target content is assigned to an area having a highest region value.Type: GrantFiled: February 16, 2012Date of Patent: October 1, 2013Assignee: Denso CorporationInventors: Hitoshi Sugiyama, Shigeo Katoh, Yoshihiro Ueda

Publication number: 20130250653Abstract: A memory includes storage elements, a signal holding part and a sense amplifier. A driving-method includes a read operation for reading target data stored in a first storage element of the storage elements. In the read operation, the signal holding part holds a first voltage according to the target data. First sample data of a first logic is written to the first storage element.

Publication number: 20130229861Abstract: In a memory, a signal holder holds voltages according to data in the storage elements. A busy-signal controller controls a busy-signal. The busy-signal determines whether to permit or reject reception of a read/write enable signal. During reception of the read/write enable signal is rejected, the signal holder holds a first to a third voltages. The first voltage corresponds to target data stored in a first storage element. The second voltage corresponds to first sample data of first logic written to the first storage element. The third voltage corresponds to second sample data of second logic. A sense amplifier detects logic of the target data by comparing a read signal of the first voltage with a reference signal generated by the second and third voltages. The write driver writes the target data/write data to the first storage element. After writing, the reception of the read/write enable signal is permitted.Type: ApplicationFiled: February 28, 2013Publication date: September 5, 2013Applicant: KABUSHIKI KAISHA TOSHIBAInventor: Yoshihiro Ueda
