Abstract

To lessen the burden of a controller having an IEEE 1394 method or the like in a network requiring the controller. A transmitting system for transmitting data from a transmitting device (51) connected to a predetermined network to a receiving device (52) connected to the network, comprises a first device 53 having a control section for requesting connection management on the network for a data transmission to another device when an instruction for the data transmission is received from the transmitting device (51) or the receiving device (52), and a second device (60) having a control section for executing the connection management for the data transmission based on the request sent from the first device (53).

Claims

1. A transmitting system for transmitting data from a transmitting apparatus to a receiving apparatus connected to a predetermined network, the system comprising:

a first controlling apparatus connected to a predetermined network, said first controlling apparatus including a first control section for preparing and transmitting a request to another controlling apparatus to execute a connection management function when the first controlling apparatus does not mount a control module of said connection management function and has been notified by said another controlling apparatus that said another controlling apparatus mounts a control module of said connection management function, said request including a request for executing the connection management to establish a connection between the transmitting apparatus and the receiving apparatus on the predetermined network and to execute data transmission from the transmitting apparatus to the receiving apparatus through the connection by using a control module of a corresponding connection management function mounted in said another controlling apparatus; and

a second controlling apparatus configured to receive said request, said second controlling apparatus including a second control section for executing the connection management function,

wherein the request includes a self-describing data structure, which provides a device control data, and

wherein the device control data includes an override DCM of the transmitting device and the receiving device.

2. A transmitting system for transmitting data from a transmitting device to a receiving device connected to a predetermined network, the system comprising:

a first device including a first control section for preparing and transmitting a request to another device to mount a connection management function from a plurality of connection management functions when the first device does not mount said connection management function and has been notified by said another device that said another device mounts said connection management function, said request including a request for executing the connection management for data transmission between the transmitting device and the receiving device; and

a second device configured to receive said request, said second device including a second control section for executing the connection management function,

wherein the request includes a self-describing data structure, which provides a device control data, and

wherein the device control data includes an override DCM of the transmitting device and the receiving device.
