Method for controlling HAVi device through non-IEEE1394 network and system therefor

A control device connected to a Home Audio Video interoperability (HAVi) network system, the control device comprising:

• a display apparatus;
• a messaging system;
• a non-IEEE1394 communications module;
• a proxy manager connected in a communicable manner through the non-IEEE1394 communications module to a non-IEEE1394 network , and connected in a communicable manner through the non-IEEE1394 network to a client proxy which is installed in a controller having a havlet in an executable manner,
• wherein said proxy manager receives a first non-IEEE1394 network message from the havlet, extracts a first HAVi message from the first non-IEEE1394 network message, sends the first HAVi message to the messaging system, receives a second HAVi message from the messaging system and transmits the second HAVi message in a second non-IEEE1394 message to the havlet,
• wherein the proxy manager comprises a first Application Program Interface (API) which generates a network connection to the client proxy and provides an identifier to the client proxy, a second API which provides information on havlets to the client proxy, a third API which provides a havlet Code Unit for installing the havlets, and a fourth API which after the havlet is executed, enables communications between the havlet and other devices or elements connected to the HAVi network system.

A controller comprising:

• a processor;
• a non-IEEE1394 communications module for communications through a non-IEEE1394 network;
• a Java virtual machine for executing a havlet;
• and
• a client proxy which downloads the havlet from an external source and installs the havlet in an executable manner, wherein the havlet converts a user control command into a HAVi message and sends the HAVi message to the client proxy, and the client proxy packages the HAVi message into a non-IEEE1394 network message which is transmitted through the non -IEEE194 network by the non-IEEE1394 communications module,
• wherein the client proxy downloads the havlet from a proxy manager installed in a control device of a Home Audio Video interoperability (HAVi) network system and installs the havlet in an executable manner, wherein said client proxy is connected in a communicable manner to the proxy manager through the non-IEEE1394 network, and
• wherein the proxy manager comprises a first Application Program Interface (API) which generates a network connection to the client proxy and provides an identifier to the client proxy, a second API which provides information on havlets to the client proxy, a third API which provides a havlet Code Unit for installing the havlets, and a fourth API which after the havlet is executed, enables communications between the havlet and other devices or elements connected to the HAVi network system.
