The present invention provides, for example, a message management apparatus in a home network for efficiently managing a predetermined message transmitted by a plurality of digital devices to each other in a home network based on HAVi (Home Audio / Video interoperability), and It is about a method.

The home network connects a plurality of digital devices so as to enable data communication between each other wirelessly or by wire, and sets a digital device having a display screen such as a digital television receiver as a controller device and has a display screen. Digital devices such as DVD players, digital video home systems (DVHS), or personal video recorders (PVRs) that are not present can be set as controlled devices so that users can control the operation of the controlled devices through the control devices. have.

When the user issues an operation command of predetermined controlled devices through a UI (User Interface) screen of the control device, the controlling device generates and sends a predetermined message according to the user's operation command, and transmits the predetermined message. The control device receives the corresponding control device, performs the corresponding operation, generates a response message according to the result of the execution of the operation command, and transmits the response message to the controlling device. The control devices confirm the operation status of the controlled device using the response message. After that, it is displayed on the UI screen to inform the user.

HAVi is known as such a home network. 1 is a diagram illustrating a general HAVi home network protocol specification. As shown here, HAVi is a device driver and hardware, RTOS (Real Time OS), IEEE 1394-1995 transaction layer (Serial Bus Manager), SBM (Serial Bus Manager) and IEC 61883 Function Control Protocol (FCP) layer And based on the IEEE 1394 interface with a CMP is a standard proposed to enable digital devices to transmit the International Standardization Organization (ISO) streams and control commands to each other.

Java is adopted as the execution engine, and seven system software elements, 1394 Communication Media Manager (CMM), messaging system, event manager, registry, and stream manager, are used to ensure the interoperability of digital devices connected to the home network. It includes a resource manager and a device control module (DCM) manager, and defines DCM and functional component modules (FCM) that represent the functions of each device. In particular, the DCM includes UI (User Interface) information for controlling each device, the UI information is delivered to the controller by the DDI (Data Driven Interaction) protocol prescribed by HAVi.

In the home network based on HAVi, when a predetermined message is transmitted to each other, the messaging system manages the message. That is, when there is a message such as a predetermined operation command or response to an operation command to be transmitted to another digital device, the message is generated by the messaging system and transmitted to the corresponding digital device through the IEEE 1394 interface. Through the IEEE 1394 interface in the corresponding digital device, the messaging system receives the message, confirms the destination of the received message, and delivers the message to the corresponding destination.

However, as the number of digital devices connected to the home network increases and the number of messages that the digital devices send to each other increases, the messaging system spends a lot of time identifying the destination of the received message when a given message is received. This takes, and there is a problem such that the message processing speed of the messaging system is delayed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a message management apparatus in a home network having a software element manager in a messaging system, wherein the software element manager generates software elements according to the source and destination of the message, thereby improving the processing speed of the message.

And a software manager software element to element management by generating according to the destination and the destination characterized in that each bar.                         

The message management method in the home network of the present invention determines whether or not a request for transmission of a predetermined message is input to a messaging system or whether a predetermined message is received through an interface cable. It is determined whether or not the message of the transmission request is a response message. If the result is not a response message, the messaging system generates a message according to the transmission request and sends it to the interface cable. The message is generated by the software element manager. Creates and stores a software element with source and destination information. In the case of a response message, a software element stored by the software element manager searches for a destination of the response message, and generates a response message based on the searched destination. If the message is received, it is determined whether or not the received message is a response message. If the message is not a response message, the software element manager generates a software element using source and destination information in the received message. To store and forward the received message to the destination, and in the case of the response message, the messaging system refers to the software element stored by the software element manager to search for the destination to which the received message is delivered and deliver the response message to the retrieved destination. It is characterized by.
