Abstract

A control apparatus is disclosed, including a first processor which can be connected to a network; and a second processor which includes a user interface, which is communicatively connected to the first processor, and which performs equipment control based on information input via the user interface and information obtained by the first processor from the network, wherein the first processor includes a communications control unit which conducts a protocol control and/or cryptographic process in communications via the network.

Claims

1. A control apparatus, comprising:

a first processor which can be connected to a network; and

a second processor which includes a user interface, which is communicatively connected to the first processor, and which performs equipment control based on information input via the user interface and information obtained by the first processor from the network, wherein

the first processor includes a communications control unit which conducts a protocol control and/or cryptographic process in communications via the network.

2. The control apparatus as claimed in claim 1, wherein

the communications control unit is a unit which hierarchically performs a process of a transport layer, an Internet layer, a data link layer, and a physical layer;

and

wherein a process of an application layer is performed in communications between the first processor and the second processor.

3. The control apparatus as claimed in claim 1, wherein

the second processor performs equipment control using data already received in between data receive processes when intermittently receiving data from the first processor.

4. The control apparatus as claimed in claim 1, wherein

information on equipment to be controlled is transmitted to the first processor when the second processor transfers to a sleep state;

and wherein

the first processor can respond to an inquiry on information for the equipment to be controlled from an external equipment unit connected to the network when the second processor is in the sleep state.

5. The control apparatus as claimed in claim 1, wherein

the second processor is a processor which controls the projecting apparatus and projects an image onto the projecting apparatus based on projecting data obtained via the network by the first processor.

6. A communications control method for a control apparatus, the control apparatus comprising:

a first processor which can be connected to a network; and

a second processor which includes a user interface, which is communicatively connected to the first processor, and which performs equipment control based on information input via the user interface and information obtained by the first processor from the network, wherein

the first processor hierarchically performs a process of a transport layer, an Internet layer, a data link layer, and a physical layer in communications via the network; and

wherein

the second processor performs a process of the application layer in communications with the first processor.
