  • Free storage space management apparatus and method
    Patent number: 7240081
    Abstract: An apparatus to be controlled has a storage and information relating to the free storage space of the storage. A control apparatus for recording information in the storage of the apparatus to be controlled by controlling the apparatus to be controlled acquires the information relating to the free storage space of the storage.

  • Data recording and reproducing apparatus, and method for recording and reproducing data without time code discontinuities
    Patent number: 6779079
    Abstract: A data recording and reproducing apparatus capable of correctly recording or reproducing data groups by linking divided data within a hard disk is provided. When a group of data such as video and music data are recorded into a hard disk to which random access is possible, file controlling information for indicating a link between the plurality of groups of data is produced from the time code of the groups of data in a time-ordered fashion. Thus-produced file controlling information is then stored in a SRAM of an operation controlling section. When the reproduction position is indicated by the time code, this position is converted into a relative position from the initial position of the file by using the file controlling information. Based on the relative position from the initial position of the file, the data is read out from the hard disk.

  • System for linking a main control unit to data receiving and transmitting units and a first and second storage units by a network
    Patent number: 6349349
    Abstract: This invention relates to an apparatus for storing and transmitting AV data. A receiving buffer unit for storing AV data temporarily, a transmitting buffer unit for storing temporarily the AV data to be transmitted, and a primary storage unit for storing AV data and a secondary storage units for storing AV data are connected to each other by means of a subnetwork. A server control unit for controlling the respective units is connected to the subnetwork. Since these units are connected by means of the subnetwork, any restriction is not given to spaces for installing the units. The capacities of the primary and secondary storage units and the transmitting buffer unit are selected so that they become larger in order of the secondary storage unit, the primary storage unit and the transmitting buffer unit. Thereby, the storage units and the transmitting buffer unit are controlled in a hierarchical form.
