摘要:
A recording medium cartridge includes a memory circuit for storing information concerning signals recorded on the recording medium 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 on the recording medium of recorded signals which the data packet 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.

A method and system for providing a user interface for a networked target device using panel subunit descriptor information maintained by the target device. The present invention utilizes a panel subunit to allow any compliant device (e.g., a target device) to describe the appearance of its physical (and logical) controls and displays to another device (e.g., an intelligent controller) and allows the controller to trigger actions on the target as if a user had physically manipulated the controls on the target device directly. The panel subunit uses objects defined with several standard types of controls and displays (e.g., push buttons, sliders, dials, LCD screens, etc.) that are commonly found on consumer electronic devices. The control types have well defined behaviors (e.g., buttons are pushed, dials are moved, values are input, etc.). In addition, the panel subunit defines a set of commands which are to be applied to any of these controls when selected by the user. The commands are defined to be sufficiently generic so that they apply to most types of controls. The panel subunit also defines generic user interaction commands (or user events) which can be applied to the controls (e.g., press, press and hold, release, input value, etc.) by a user. The purpose of these user events is to encapsulate the typical user manipulated action for the controls and to let the target device decide the manner in which to interpret the user actions on its own. A status descriptor keeps the intelligent controller informed of the status of the target device being manipulated.

A network system wherein any device in all networks can be represented using addresses set in the individual networks without relying upon the concept of a network number is disclosed. A first network (1) includes first to third devices (A, B, C) to which the addresses of "1", "2" and "3" are allocated, respectively. A second network (2) includes first to third devices (D, E, F) to which the addresses of "1", "2" and "3" are allocated, respectively. A third network (3) includes first and second devices (G and H) to which the addresses "1" and "2" are allocated, respectively. The first and second networks (1, 2) are connected to each other by way of a gateway (GW1) for which the address 4 in the first network (1) and the address 5 in the second network (2) are allocated. The second and third networks (2 and 3) are connected to each other by way of another gateway (GW2) for which the address 4 in the second network (2) and the address 3 in the third network (3) are allocated to build up a network system. A pass from within a network to another device in another network is represented in a compound representation using the addresses set in the individual networks. For example, the pass from the first device (A) in the first network 1 to the second device (H) in the third network (3) is represented as "4.4.2".

When transmitting data such as audio data which require protection to be provided, difficulty levels of authentication are switched corresponding to processing power of equipments to communicate. Thus, for an equipment of low processing power may perform a Bluetooth communication based on the SDMI. Further, for a communicating counterparty which is an equipment of high processing power, such as a personal computer, sufficient countermeasures against hacking may be taken.

A communications system connected via a bus capable of transferring combinations of control signals and AV signals as packets while providing an environment which is the same as an environment where connections are made using analog signal lines. A register decided by an address is taken to be a virtual plug for each item of equipment. The plug enable for the input plug is set to 1 and a synchronous communication packet for the AV signal from the channel set by the channel number is received. The plug enable for the output plug is set to one and the synchronous communication packet for the information signal is sent to the channel set by the channel number at a transmission speed designated by the DR (Data Rate) at the bandwidth expressed by “Bandwidth”.

A communication command system controls communications between equipment having sub-devices for outputting different types of communications. A bus with different channels is connected to the input/output ports of the equipment to send communications back and forth between the equipment. A switch switches the connection between the sub-devices and the bus channels. A command master commands the switch to switch a particular sub-device to a particular bus channel and, in this manner, communications are set up between sub-devices of different equipment.

An apparatus and method for editing isochronous communication data used for communication between various electronic devices. An editing procedure with high accuracy can be conducted without reading the system data of isochronous communication in a system having co-existing isochronous and asynchronous modes of communication for data transmission between the electronic devices. The editing procedure can also be conducted with high accuracy in a system in which an edit controlling device cannot recognize the frame boundary in the information signals. Furthermore, even if there are various time delays associated with the instruction reception and the instruction execution by an electronic device, the editing procedure can be conducted with high accuracy.
