Abstract

A method of controlling connection between nodes in a digital interface whereby a first node that is a master node determines a second node to be the master and controls a point-to-point connection or a broadcast connection to another node. The first node having the display device determines the second node to be the master in accordance with a user selection, and transmits a connection command of a predetermined format for transmitting a data stream to the second node. The second node determined as the master in accordance with the transmitted connection command of the predetermined format is allocated with a channel and a bandwidth from an isochronous resource manager (IRM), and performs a point-to-point connection between the second node and the first node to transit the data stream. Thus, the transmission/reception, reproduction, and control of the data stream of the program can be smoothly performed.

Claims

1. (canceled)

2. A method for controlling a connection between a plurality of nodes through an interface, comprising:

transmitting control information from a first node to a second node, the control information including identification information of the second node and a disconnection command, wherein the second node is operated to be disconnected with the interface based on the disconnection command; and

receiving, according to the control information, a response information including identification information of the first node.

3. The method of claim 2, wherein the second node maintains a disconnection state until a new connection is established.

4. The method of claim 3, wherein the new connection is established when a connection command is detected.

5. The method of claim 4, wherein during the disconnection state, a physical connection between the first node and the second node is maintained to receive the connection command through the interface.
