Abstract
An IDE interface unit (11) reads out a value of an ATA register in a DVD drive (1) repeatedly and sends the value to a host network interface device (4a). The host network interface device (4a) retains the register value in a shadow register (23). An IDE interface unit (21) sends a value of the shadow register (23) to a DVD decoder (2) (host) upon receiving a reading out signal of a register value in the ATA register (31). Thus, since a register reading out controlling signal is not sent via networks, there is no transmission delay that effects to the network.

5. A drive network interface device that is connected between a drive that is able to do at least any one of reading and writing, and a network, comprising:
-
a network connecting unit operable to establish a communication with the network; and
a substitution unit, which is connected to the drive for communication, operable to execute a series of information sending and receiving processing with a disk as a substitute for a partner'"'"'s device and send only the entity information to the partner'"'"'s device via the network connecting unit and the network upon receiving information from the partner'"'"'s device. - View Dependent Claims (6, 7, 8, 9, 10)

24. A communication system that sends and receives an information between a host and a drive that is able to do at least any one of reading and writing, with a direct connection basis via a network, comprising:
-
a first interface device that is connected between the host and the network;
a second interface device that is connected between the drive and the network; and
an information distinction unit, that is connected to any one of the first interface device and the second interface device, operable to distinguish an entity information for being transferred between the host and the drive from a communication proceeding information for transferring the entity information among the information, wherein the first interface device includes;
a first substitution sending and receiving unit operable to send and receive the communication proceeding information to and from the host substituting for the drive; and
a first entity information sending and receiving unit operable to send and receive the entity information to and from the second interface device, and the second interface device includes;
a second entity information sending and receiving unit operable to send and receive the entity information to and from the first interface device; and
a substitution sending and receiving unit operable to send and receive the communication proceeding information to and from the drive as a substitute for the host.

25. An information transmitting method for transmitting a certain content of a communication data from a first device to a second device via a communication network, including:
-
a step for receiving the communication data while communicating a control data for controlling a transmission with the first device, in a first interface device connected between the first device and the communication network;
a step for sending only the communication data received from the first device to a second interface device connected between the second device and the communication network via the communication network, in the first interface device; and
a step for sending the communication data received from the first interface device to the second device while communicating the control data with the second device for controlling a transmission, in the second interface device. - View Dependent Claims (26, 27)
