Control apparatus which remotely controls a device in a network system and control method therefor
A television receiver serves as a control which remotely controls a device in a network system, and is provided with a remote controller for remotely controlling the television receiver itself. The television receiver displays, on a display device, a graphical user interface (guide panel) for graphically guiding the functions assigned to the plural numeral keys provided in the remote controller. Such configuration allows the user to remotely control the desired AV device in the network system in a simple manner with a limited operation sequence.
1. A control apparatus which remotely controls a device in a network system, comprising:
a remote controller for remotely controlling said control apparatus;
communication means for downloading a control program for remotely controlling an unknown device; and
control means for generating, according to the downloaded control program, a graphical user interface for graphically displaying functions assigned to a plurality of keys provided in said remote controller.
2. A control method for a control apparatus which remotely controls a device in a network system and has a remote controller for remotely controlling said control apparatus, said method comprising steps of:
downloading a control program for remotely controlling an unknown device; and
generating, according to the downloaded control program, a graphical user interface for graphically displaying functions assigned to a plurality of keys provided in said remote controller.
3. An apparatus according to claim 1 , wherein said communication means starts to perform a process of downloading the control program if said control apparatus detects that said unknown device is connected to the network system.
4. An apparatus according to claim 1 , wherein said control apparatus is a television receiver.
5. An apparatus according to claim 4 , wherein said communication means start to perform a process of downloading the control program if said control apparatus detects the said unknown device is connected to the network system.
6. A method according to claim 2 , wherein said downloading step starts to perform a process of downloading the control program if said control apparatus detects that said unknown device is connected to the network system.
7. A method according to claim 2 , wherein said control apparatus is a television receiver.
8. A method according to claim 7 , wherein said downloading step starts to perform a process of downloading the control program if said control apparatus detects that said unknown device is connected to the network system.
9. A control apparatus which remotely controls a device in a network system, comprising:
a remote controller adapted to remotely control said control apparatus;
a communication unit adapted to download a control program for remotely controlling an unknown device; and
a control unit coupled to said communication unit, and adapted to generate, according to the downloaded control program, a graphical user interface for graphically displaying functions assigned to a plurality of keys provided in said remote controller.
10. An apparatus according to claim 9 , wherein said communication unit starts to perform a process of downloading the control program if said control apparatus detects that said unknown device is connected to the network system.
11. An apparatus according to claim 9 , wherein said control apparatus is a television receiver.
12. An apparatus according to claim 11 , wherein said communication unit starts to perform a process of downloading the control program if said control apparatus detects that said unknown device is connected to the network system.
