Method of controlling connection between nodes in digital interface
First Claim
1. A method for controlling a connection through a serial bus, comprising:
- receiving a control command that identifies a destination node and describes a requested state of the connection, from a source node, the requested state of connection including a command indicating whether the destination node is operated to be connected or disconnected with the serial bus; and
transmitting, based on receiving the control command, a response command describing a current state of the connection, to the source node, the response command including identification information of the source node.

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.
