Abstract

An image display apparatus includes a memory for holding in advance, of the one or more information terminal apparatuses connected via a network, information of information terminal apparatuses whose connection to the network is desired, a controller for reading out the information of the information terminal apparatuses stored in the memory, and display section for displaying a list of the information of the information terminal apparatuses. In this case, the image display apparatus further includes selector for selecting one information terminal apparatus from the list displayed on the display section, it is able to change the connection of the information terminal apparatus to desired information terminal apparatus by manipulation of the selector on a display screen.

Claims

1. An image display apparatus including a display section and communications means, and in which image information sent from one or more information terminal apparatuses via a network is received by the communications means and an image based on the image information is displayed on the display section, comprising:

holding means for holding in advance, of the one or more information terminal apparatuses, information of information terminal apparatuses whose connection to the network is desired;

control means for reading out the information of the information terminal apparatuses held by the holding means;

image signal output means for generating an image signal for displaying, on the display section, a list of the information of the information terminal apparatuses read by the control means; and

selecting means for selecting one information terminal apparatus from the list displayed on the display section, wherein

the control means generates a connection request signal with respect to the information terminal apparatus selected by the selecting means, and

the communications means transmits the connection request signal from the control means.

2. The image display apparatus as cited in claim 1, wherein

the communications means receives the image signal after receiving an acceptance response signal from the information terminal apparatus corresponding to the connection request signal.

3. The image display apparatus as cited in claim 2, wherein

when the information terminal apparatus performing the reception is changed to another information terminal apparatus by the selecting means,

the control means controls the communications means to transmits a disconnection request signal to the connected information terminal apparatus, to receive an acceptance response signal from the connected information terminal apparatus, and after the connection is disconnected, to transmit a connection request signal to another information terminal apparatus.

4. The image display apparatus as cited in claim 3, wherein

when the communications means receives a rejection signal from the information terminal apparatus selected by the selecting means, the control means controls to display that it is not able to connect to the selected information terminal apparatus.

5. The image display apparatus as cited in claim 3, wherein

when changed to another information terminal apparatus,

the control means controls the communications means to transmit a disconnection request signal to the connected information terminal apparatus, and to suspend to transmit a connection request signal until an acceptance response signal from the connected information terminal apparatus is received.

6. An image display system comprising:

one or more information terminal apparatuses connectable to a network; and

an image display apparatus for receiving a transfer of image information via the network from the one or more information terminal apparatuses and for displaying on a display section an image based on the image information, wherein

the image display apparatus includes;

holding means for storing and holding in advance, of the one or more

information terminal apparatuses, information of information terminal apparatuses whose connection to the network is desired;

control means for reading the information of the information terminal apparatuses held by the holding means;

image signal output means for generating an image signal for displaying, on the display section and, as a list, the information of the information terminal apparatuses read by the control means; and

selecting means for selecting one information terminal apparatus from the list displayed on the display section, and wherein

the control means generates a connection request signal with respect to the information terminal apparatus selected by the selecting means;

the communications means transmits the connection request signal generated by the control means; and

the selected information terminal apparatus includes communications means, and control means, wherein

when the control means controls the communications means to receive the connection request signal, the control means determines whether connection to the image display apparatus or not, and when determined that the connection is possible, then the control means controls the communications means to transmit an acceptance response signal, and to transmit the image information.

7. An image display method for an image display apparatus that receives image information sent from one or more information terminal apparatuses via a network and displays an image based on this image information, said image display method comprising:

a holding step of storing and holding in advance, of the one or more information terminal apparatuses, information of those whose connection to the network is desired;

a reading step of reading the information of the information terminal apparatuses held in the holding step;

a displaying step of displaying, as a list, the information of the information terminal apparatuses that are read;

a selecting step of selecting one information terminal apparatus from the displayed list; and

a transmitting step of generating and transmitting a connection request signal with respect to the selected information terminal apparatus.

8. The image display method as cited in claim 7, further comprising:

a reception step of receiving an acceptance response signal from the selected information terminal apparatus in response to the connection request signal; and

a reception step of receiving the image information after the acceptance response signal is received.
