Abstract: A recording and reproducing apparatus records and reproduces video signals which include video information and copy protection information for restricting the number of times the video information may be copied. Original video information is recorded onto a recording medium with updated copy protection information that indicates that the video information has been copied and is also transmitted with the original copy protection information so that more than one copy of the video information may be generated from the original. The transmitted video information is outputted and/or recorded onto a recording medium with the updated copy protection information.

Abstract: One node is selected from a plurality of candidates for a bus management nod e. A bus management node 11 has a register for channels in use REG 1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG 1 and t he register for channels in use REG1 in order to read out their contents for ascertainin g the number of the un-used channel and the residual capacity. If there is any un- used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG 1 and REG2 so that the number of the channel to be in us e and the capacity of the bus to be in use will be stored in the register for channels in use REG 1 and the bus capacity register REG2. This enables bus management to be achiev ed easily in a system performing synchronous communication between plural nodes connected to the bus.

Abstract: A bus management node 11 has a register for channels in use REG1 and.a b us capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG1 and the bus capacity register REG2. When carrying out the writing in REG1 an d REG2, the node 12 compares read channel state information and read bus sta te information read out by the read-out command with channel state information and bus state information in REG1 and REG2 respectively. If the read channel information and the bus state information are identical to the channel state information and the bus state information in REG1 and REG2 respectively, it writes new channel information and new bus state information. This makes it possible to elimina te the possibility of wirting by other nodes.

Abstract: An enciphering/deciphering apparatus and method are provided by which illegal copying can be prevented with a greater degree of certainty. Data enciphered by a 1394 interface (26) of a DVD player (1) is transmitted to a personal computer (2) and a magneto-optical disk apparatus (3) through a 1394 bus (11). In the magneto-optical disk apparatus (3) with which a change to a function is not open to a user, the received data is deciphered by a 1394 interface (36). In contrast, in the personal computer (2) with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key (50) by a 1394 interface (49), and a result of the decipherment is further deciphered using a session key by an application section.

Abstract: A recording and reproducing device provided with at least a pair of rotary heads having different azimuths, running control means which controls the running of a magnetic tape, and recording timing control means which controls the recording by the rotary heads so that the recording can be performed in a first period when digital data having a first data rate are inputted, whereby the digital data can be recorded on the magnetic tape at the recording timing of the recording timing control means. In addition, the recording and reproducing device is also provided with a memory means which temporarily stores digital data supplied from the outside, reading means which reads out the digital data stored in the memory means, and signal processing means which performs a prescribed process of the digital data read out from the memory means. When digital data having a second data rate which is different from the first data rate are inputted, the recording timing control means and reading-out means perform processes at a speed based on the ratio between the two data rates and, at the same time, the running control means controls the running speed of the magnetic tape based on the data rate ratio.

Abstract: A recording medium cartridge (31) includes a memory circuit (34) for storing information concerning signals recorded on the recording medium (6) within the cartridge. The information is stored in the memory circuit in the form of a hierarchic data structure which includes a plurality of data packets having a predetermined form and length. Each data packet includes a code indicative of a level in the data structure to which the data packet belongs. At least some of the data packets include data indicative of starting and ending positions (2, 3) on the recording medium of recorded signals which the data packets represents. The hierarchic (or "tree") data structure facilitates rapid retrieval and reproduction of the signals recorded on the recording medium, particularly when the recording medium is a magnetic tape. The tree structure also facilitates storage of information in connection with recording of additional signals on the recording medium.
