Abstract: A video server includes a memory device; a receiving device that acquires contents data; a server control device that stores, into the memory device, the contents data acquired by the receiving device, the server control device that reads the contents data out of the memory device. The memory device includes a semiconductor memory device; and a memory control device that stores and reads, the contents data in a first unit of area and performs a read-retry-operation of re-reading the contents data out of a first area in the first unit of area if detected an error on the contents data read out of the first area of the semiconductor memory device in the first unit of area, and moves the contents data into a second area if a number of times of performing the read-retry-operation by the memory control device reached at a first number of times of read-retry-operations.

Abstract: A video file creation device according to an embodiment includes an encoder, a metadata acquisition unit, a file creation unit, and a data storage unit. The encoder is configured to create compressed video data from a video stream. The metadata acquisition unit is configured to acquire metadata related to the video data. The file creation unit configured to create a file in an MXF format having a metadata section formed of a metadata recording area and an additional writing area. The acquired metadata is recorded in the metadata recording area. The data storage unit configured to record the file in the MXF format created by the file creation unit.

Abstract: A video server controller has an instruction receiver, a command forming unit, and a command issuing unit. The instruction receiver receives the first instruction for recording the material data name of the program material data and the time code indicating the site of interruption of broadcasting of the program material data, and a second instruction for restarting broadcasting of the program material data from the interruption site. The command forming unit, upon receiving the first instruction, stores the material data name and the time code, and upon receiving the CUE UP WITH DATA command as the second instruction, which is standard to the VDCP protocol, the stored material data name and time code are read out. The command issuing unit issues the CUE UP WITH DATA command, the material data name, and the time code to the video server.

Abstract: There is provided a control program executable in a computer to control a plurality of control-object devices connected to a network. The control program is separately started for each of the control-object devices. The control program is configured to perform a setting step and a saving step. The setting step comprises modifying contents of relevant data of the control-object devices or the control program. The saving step comprises saving the relevant data in a memory in different saving forms in association with respective control-object devices. It is possible to easily perform a separate control of the plurality of video servers, even when a plurality of control-object devices is controlled by one device.

Abstract: To realize efficient processing regarding accesses to files. A remote controlling processing apparatus 14 of a file sharing system 10 is connected via a network 15 to a controlled processing apparatus 12 including a file storage part 17 in which a plurality of files 1, 2, 3 . . . are stored. Further, the remote controlling processing apparatus 14 includes: an access request generating part 19 generating access requests to the files 1, 2, 3 . . . in the file storage part 17; an access request storage part 22 in which the plural generated access requests are sequentially stored; and an access request notifying part 25 integrating plural ones of the access requests in the access request storage part 22 based on a storage status in the access request storage part 22 to notify the integrated access request to the controlled processing apparatus 12.

Abstract: A playback apparatus for a storage content which can automatically stop playbacking one or a plurality of content data stored in a storage medium without recognizing a stop code by playbacking the content data is provided. The stop code is added to the metadata differently from the content data and is stored in medium unit 11. Control unit 13, by using the stop code obtained from the metadata, can automatically stop playbacking the content data during the playback at a designated position. In addition, by random accessing the storage medium at a frame designated by the stop code, to cue up or to move to the broadcasting start point of the program can be performed instantaneously.
