Method of controlling connection between nodes in digital interface

摘要

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.

1. 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 connection command, wherein a connection between the second node and a third node is established based on the connection command, wherein the second node and the third node maintain a connection state until a disconnection command is detected, and wherein during the connection state a physical connection between the second node and the third node is maintained to receive the disconnection command through the interface; and receiving, according to the first control information, a response information including an identification information of the first node.
