The present invention relates to a home network device and a method of transmitting sound information using the same, and more particularly, a home network device capable of controlling a controlled device through a user interface transmitted from a controlled device connected to a home network, and sound information. And a sound information transmission method using the same.

A home network system connects devices in a home to enable communication between people and people, devices and devices, and people and devices. This makes it easier to control devices in the home without the constraints of space and devices, and to provide a wider variety of services. It is a technology that improves the quality of life by being provided.

Such a home network system may be composed of a digital television, in which a user controls devices in the home network through a user interface, and a controlled device such as a PDA, a set-top box controlled by a control device, and a controlled device such as a DVD player. have.

In this case, the control device provides a user interface for the predetermined controlled device, and the user controls the predetermined controlled device through the provided user interface. On the other hand, the control device may be equipped with a user interface for controlling all controlled devices connected through the home network, but since the user interface for newly added controlled devices is not installed in the home network, a separate download is required. This creates a hassle for providing a user with a user interface for a newly added controlled device.

Therefore, in recent years, even when the control device does not mount a user interface for a predetermined controlled device, the control device provides the user with a user interface transmitted from the corresponding controlled device. Therefore, the user can control the controlled device even when the control device does not mount the user interface of the corresponding controlled device.

As described above, the technology for providing the user with a user interface transmitted from the controlled device to the user is standardized by Intel's XRT, Samsung's XHT, and the like.

1 is a diagram illustrating a home network system according to the related art.

As shown, the home network system 10 according to the prior art includes a controlled device 11 and a controlled device 12.

The controlled device 11 transmits a user interface generator 11a for generating a user interface to be transmitted to the control device 12 connected through the home network 13, and sends the generated user interface to the control device 12. A communication unit 11b for receiving a user interface request from the control device 12, and a control unit 11c for controlling generation and transmission of a user interface according to the request of the control device 12.

The control device 12 requests the user interface to the display unit 12a and the controlled device 11 displaying the user interface transmitted from the controlled device 11 connected through the home network 13, The communication unit 12b for receiving the user interface according to the control, and the control unit 12c for controlling the display of the received user interface and the request of the user interface under the control of the user.

In this case, the home network system of FIG. 1 provides the user interface transmitted from the controlled device to be controlled by the user so that the user can control the controlled device even if the user does not know the details of the controlled device.

However, when an event occurs due to another control device in the controlled device or when an event occurs due to a change in the state of the controlled device, whether or not the event occurs is unknown.

In other words, the user interface already displayed through the control device does not reflect the state change caused by the occurrence of the event in the controlled device, and thus may not operate normally.

For example, if a controlled device was in a playback state when a user interface sent from a controlled device was displayed on the control device, and playback was stopped due to a device failure in the controlled device, the controlled user interface was previously displayed on the controlled device. There is no way to tell if the device has failed.

In order to solve this problem, Korean Laid-Open Patent Publication No. 2005-0018317 can easily control a controlled device in a convenient way without knowing the details of the controlled device, and control when an event occurs in the controlled device. Disclosed is a method for easily detecting whether an event has occurred in a device.

However, in this case, although the control device may detect an event according to the change of the state of the controlled device, it may transmit sound information, for example, a warning sound or an effect sound, to the control device according to the change of the state of the controlled device. If necessary, it does not disclose a method for solving the problem.
