A controller, method and computer medium are provided for controlling communications between a control area network and a data network. The method includes receiving user input at a controller coupled to the control area network from a node coupled to the data network, receiving user input at the controller from a node coupled to the control area network, and instructing an internet appliance coupled to the control area network to perform a command based on at least one of the received user inputs.

Internet control system communication protocol, method and computer program

Remote control

A control system, method and computer program are provided for communicating control information in a control system. The control system includes a master controller and a plurality of devices. Each of the plurality of devices have a number of channels. Each channel has an identifying number and a plurality of channel states. The method includes at least initially directing one or more messages sent to and from each device to the master controller, sending a first type of control message from the master controller to respective devices, and sending a second type of control message and a third type of control message from the master controller to respective devices. A control message of the first type directs the respective device to place one of its channels in a specified channel state. A control message of the second type directs the respective device to set the level of a specified parameter to a certain value, and a control message of the third type comprises a character string of variable length.

A system of multimedia display on a monitor screen includes at least one graphics source, a display file defining a page having a plurality of buttons, where each button has a set of properties including a specification of a graphics source. The system further includes a graphics controller operable to generate a pixel map, and a graphics arbitrator coupled to the graphics controller operable to select pixels between the pixel map and pixels from the at least one graphics source to be displayed for the page according to the display file.

System and method for multimedia display

A control system of the present invention includes at least one device, a network interconnecting the at least one device, a control network portal coupled between the network and the Internet, and a master controller coupled to the network and operable to control the operations of the Internet and the at least one device, the Internet is controllable as a device coupled to the network.

Internet control system and method

Remote controller

A master controller in a control area network system in a larger control area network may have a plurality of devices coupled thereto. The master controller may further include a device manager which provides a virtual device. The virtual device operates to link a state associated with the virtual device to a plurality of states associated with the devices such that the respective states are maintained in a substantially similar condition. The substantially similar condition is maintained by propagating a change in the state of the virtual device to a change in the state of the devices and a change in the state of one or more of the devices is propagated to the virtual device and all other devices.

Method and system for operating virtual devices by master controllers in a control system

A communication protocol includes a packet protocol, which includes a protocol field for indicating the type of protocol, a length of data field for listing the length in bytes of the data field, a data field containing sub protocol data, and a checksum for determining the integrity of the packet.

Internet control system communication protocol and method

A master controller ( ) in a control area network system in a larger control area network ( ) may have a plurality of devices ( ) coupled thereto. The devices generate data which the master controller directs to a destination device coupled to the same master controller, a different master controller in the same control area network or to a different master controller in a different control area network. The master controller directs the data using a connections table acquired from one or more other master controllers to which the master controller may communicate with.

Method and system for master to master communication in control systems

A master controller in a control area network system in a larger control area network may have a plurality of devices coupled thereto. Software and firmware on the master controller may be updated using an FTP server to contact a content provider in order to retrieve upgrades, updates and patches for the software and firmware on the master controller. In addition, a user may user a web browser in order to perform remote updates over the Internet.
