摘要： A controller issues a command to an HDD interface to transfer AV data stored in HDDs to a memory. The HDD interface, in compliance with the command, transfers the AV data stored in the HDDs to a memory mapped on a bus. A memory controller reads the AV data out of the bus, and writes the AV data into the memory. The controller outputs the address of the AV data to be outputted to the memory controller. The memory controller reads out the AV data of the designated address, and outputs them to an AV data output interface. And the AV data output interface outputs the AV data. The controller issues a command to the HDD interface memory to record the AV data stored in the memory into the HDDs. The HDD interface, in compliance with the command, reads the data out of a memory mapped on the bus, and stores them in the HDDs. The memory controller reads the AV data out of the memory, and outputs them to the bus. At the same time, the controller designates to the memory controller the address in the memory into which the AV data inputted from the AV data input interface are to be written. The memory controller reads the AV data out of the AV data input interface, and writes them into the designated memory. By accomplishing this series of actions in synchronism with the frame period, AV data are stored in the HDDs, and also AV data stored in the HDDs are outputted.

摘要： A method for transmitting data when a system detects the amount of data which can be transferred, and divides the data to be transferred into a plurality of data blocks to form a list. A transfer device refers to the list and carries out input and output processing between a VTR or a network and a memory. Thus, the data can be efficiently transmitted at high speed with high reliability and independent of system configuration. Additionally, the data can be rearranged in the course of its transmission.

摘要： A transmission device, which continues consistent secure communication, even if a frame counter is reset due to a power cut off, includes a transmission frame counter that counts a value monotonically incremented for each packet transmission and holds the value as a frame counter value. The transmission device includes a transmission unit that adds the frame counter value held in the transmission frame counter to a packet, and transmits the packet to the reception device, and a storage circuit that stores the frame counter value. The transmission frame counter (i) stores the counted and held frame counter value into the storage circuit for each stored-frame-counter updating increment that is a natural number greater than an increment by which the frame counter value is monotonically incremented, and holds, as a new frame counter value, the stored frame counter value added with the stored-frame-counter updating increment, when the transmission device is reset.

摘要： Input digital data are formatted into a data block composed of a predetermined amount of data, subjected to error correction encoding process, and recorded on a predetermined number of continuous tracks of a recording medium. In the error correction encoding process, the data block is subjected to an inter-track error correction encoding, an outer error correction encoding and an inner error correction encoding. In the inter-track error correction encoding, each information element to be coded is produced by symbols collected from the data which are to be recorded on different tracks of the continuous tracks. The error correction encoded data in the data block are distributed to a first predetermined recording area of each track of the continuous tracks, and parity code words produced by the inter-track error correction encoding are distributed to a second predetermined recording area of each track of the continuous tracks.

摘要： A transmission device can continue secure communication having a consistency between a frame counter of a transmission device and a frame counter of a reception device without bothering a user, even if the frame counter is reset due to battery exchange, power cut off, or the like. The transmission device includes: a transmission frame counter (20) that counts a value monotonically incremented for each packet transmission and holds the value as a frame counter value; a transmission unit that adds the frame counter value held in the transmission frame counter (20) to a packet, and transmits the packet to the reception device (200); and a transmission frame counter storage circuit (23) that stores the frame counter value. The transmission frame counter (20) (i) stores the counted and held frame counter value into the transmission frame counter storage circuit (23) for each stored-frame-counter updating increment that is a natural number greater than an increment by which the frame counter value is monotonically incremented, and (ii) holds, as a new frame counter value, the frame counter value stored in the transmission frame counter storage circuit (23) added with the stored-frame-counter updating increment, when the transmission device (100) is reset.
