ABSTRACT:
When a connection mode change setting instruction input entered by a user is supplied to the control unit20, the control unit20controls the IEEE 1394 I/F circuit to set the value of oPCR and iPCR of an electronic apparatus for forming a channel so that the channel between target electronic apparatus is formed in the connection mode instructed by the user. Thereby, a channel between electronic apparatus is formed flexibly and an information output apparatus that is capable of forming a convenient electronic apparatus network is provided. One electronic apparatus connected to the digital bus inquires of an electronic apparatus connected to the digital bus whether it is a monitor apparatus (first receiving apparatus) that receives the data mainly through a channel formed in the broadcast connection mode or not, and channels connected in the broadcast connection mode are allocated to monitor apparatus respectively. A receiving apparatus other than the monitor apparatus forms a channel of the PtoP mode avoiding the channel of the first connection mode allocated to the first receiving apparatus, and receives supply of the data. As the result, a transmission line using method, an information transmission system, and an electronic apparatus that are capable of utilizing a plurality of channels on the digital bus efficiently, and capable of providing the convenient digital content using environment are realized.
