Device and method for switching receiving/recording device in a broadcasting connection/point-to-point connection bus enviroment
First Claim
1. An information processing device comprising:
- a plurality of external devices connected to each other via a bus, said bus including a plurality of channels;
wherein said plurality of external devices includes at least one receiving device and at least two transmitting devices;
selection means for allowing a user of said at least one receiving device to select at least one of said two transmitting devices;
first establishing means for establishing concurrently a point-to-point connection and a broadcast connection between said at least said one receiving device and said one of said at least two transmitting devices on at least one of said plurality of channels of said bus; and
switching means for allowing said user of said at least one receiving device to switch to a second of said at least two transmitting devices by canceling the point-to-point connection established by said first establishing means and permitting only said broadcast connection established by said first establishing means in order to perform desired operations when said switch occurs.

Abstract
An information processing device, method thereof and a recording medium for easily switching input signals. A broadcast connection and a point-to-point connection are established between the receive device and the transmit device. When the user commands the canceling of the P.P. connection established for the receive device or the transmit device, only the broadcast connection remains established. In this state, the user receives signals on a receive device sent from the desired transmit device, and commands the restoring of the P.P. connection with the desired transmit device. The switching of input signals to the receive device is in this way performed by temporarily canceling the P.P. connection.

7. An information processing method, comprising:
-
a plurality of external devices connected to each other via a bus, said bus including a plurality of channels;
wherein said plurality of external devices includes at least one receiving device and at least two transmitting devices;
a selecting step for allowing a user of said at least one receiving device to select at least one of said two transmitting devices;

13. A recording medium recorded with a program capable of being loaded by a computer, wherein said program comprises:
-
a plurality of external devices connected to each other via a bus, said bus including a plurality of channels;
wherein said plurality of external devices includes at least one receiving device and at least two transmitting devices;
a selecting step for allowing a user of said at least one receiving device to select at least one of said two transmitting devices;
a first establishing step establishes a point-to-point connection and a broadcast connection between at least said device and said one of said at least two transmitting devices on at least one of said plurality of channels of said bus; and
a switching step for allowing said user of said at least one receiving device to switch to a second of said at least two transmitting devices by canceling the point-to-point connection established by said first establishing step and permitting only said broadcast connection established by said first establishing means in order to perform desired operations when said switch occurs. - View Dependent Claims (14)
