Broadcasting system and method for control of broad-casting system

The present invention relates to a broadcast system and a method for controlling the broadcast system, and more particularly, to a broadcast system and a method for controlling the broadcast system to allow the central management server of the broadcast system to monitor and control the operating state of each broadcast terminal. .

Recently, with the development of information and communication technology, various video contents such as analog movies, dramas, music videos, etc. are being digitized, and the digitized video contents are provided to users through an information communication network. If the user has a device capable of displaying video content, the user can be provided with the desired video content at his / her desired time to watch.

On the other hand, with the development of data communication technology, an IP Set-Top Box (IP-STB) has been developed and used to perform data communication on a network through a set-top box.

A set-top box (STB) is connected to a display device such as a television (for example, a television) to transmit a request signal for data required by the user and receive data from a data providing server and provide the user with the data. It is a home subscriber signal conversion device that allows.

The IP set-top box provides a function of allowing the IP set-top box to be connected between the communication network and the display device and connected to the communication network through the display device, as the IP set-top box performs networking using a computer and a monitor connected to the communication network.

Accordingly, when the IP set-top box is enabled to use a display device, not only simple web surfing but also an on-demand video service, ie, a video on demand (VOD) service, can be implemented by networking instead of a conventional passive broadcasting.

Such a broadcast system provides a subscriber with an interactive service through a set top box, and the subscriber may receive additional information related to the existing broadcast and various additional services other than the broadcast.

That is, when the user selects a video program to be watched through the display apparatus, the service provider transmits the selected video program to the set top box through the communication network so that the user can watch. Such on-demand video services may be used for ordering digitally transmitted movies, watching educational videos, video conferencing, and the like.

However, in the broadcasting system as described above, the service is provided by mutual control with the IP set-top box and the content providing server. Therefore, it is impossible to directly control the display device by the content providing server.

That is, as the monitoring and control of the operation state of each display device is impossible, the content providing server may unnecessarily transmit data to the display device.

For example, if the display device is powered off, the content providing server cannot detect this and continue to provide content to the IP Settop box. In this case, the content providing server and the IP set-top box perform unnecessary data transmission, resulting in waste of resources of the content providing server and waste of power of the IP set-top box.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a broadcast system and a control method of the broadcast system to monitor and control the display device directly from the content providing server.

A broadcast system according to the present invention for achieving the above object, in a broadcast system by a content providing server for providing a video content, a communication network for transmitting the video content, and the video content provided through the communication network A set-top box for processing, a display device connected to the set-top box for displaying the video content, retransmitting a response signal according to a control signal of the content providing server, and providing the video content through the communication network; And a content providing server which transmits a control signal of the apparatus and controls the display apparatus according to the response signal of the display apparatus.

The content providing server includes a communication interface for accessing the communication network, and a device management module for accessing the communication network through the communication interface and transmitting and receiving a control signal of the display device to control the display device.

The set top box stores a network ID of the display device and provides the display device with the video content and the control signal provided from the content providing server.

The display device may include a communication interface connected to the communication network through the set top box, a management module for detecting an operation state of the display device and resending a response signal according to a control signal of the content providing server through the communication interface; And a control unit controlling an operation of the display apparatus according to a control signal transmitted to the management module.

A control method of a broadcast system according to the present invention for achieving the above object, in a broadcast method by a content providing server for providing a video content, the control signal from the content providing server to the display device for displaying the video content; Transmitting, by the display apparatus, retransmitting a response signal according to the control signal, and transmitting the control signal for controlling an operation state of the display apparatus based on the response signal from the content providing server. To control.

In the resending of the response signal according to the control signal, the content providing server terminates the control of the display apparatus when there is no response signal of the display apparatus.

According to the control method of the broadcasting system and the broadcasting system according to the present invention, there is an effect of preventing unnecessary data transmission and power loss of the server by directly monitoring and controlling the display apparatus in the server.

Accordingly, the operation of the broadcasting system according to the present invention will be described in detail through the embodiment. Each element mentioned below should be understood with reference to the above description and drawings.

5 is a flowchart illustrating a control method of a broadcast system according to the present invention.

First, in describing the broadcasting system according to the present invention, descriptions of individual operations of the content providing server 100, the set-top box 400, and the display apparatus 500 constituting the broadcasting system are omitted, and the content providing server 100 and Only the signal processing related to the monitoring and control of the display apparatus 500 between the display apparatuses 500 will be described.

First, the content providing server 100 reads the operation state of the display apparatus 500 prior to providing the image content. The device management module 120 of the content providing server 100 transmits a control signal for reading the operation state of the display apparatus 500 (step S110).

In this case, the control signal transmitted from the device management module 120 includes the network ID of the display apparatus 500 to be controlled and is transmitted to the display apparatus 500 through the set top box 400 storing the network ID. .

In response, the display apparatus 500 retransmits the response signal in response to the control signal transmitted from the content providing server 100. The response signal retransmitted includes the operation state and the setting state of the display apparatus 500, and the response time signal is not retransmitted when the operation of the display apparatus 500 is stopped.

Here, the content providing server 100 determines whether a response signal is transmitted from the display apparatus 500 and controls the display apparatus 500. In this case, when the response signal is not transmitted from the display apparatus 500, it is determined that the power of the display apparatus 500 is turned off and no further control is performed (step S120).

Meanwhile, the response signal retransmitted by the display apparatus 500 is transmitted to the communication network 300 through the set top box 400 through the communication interface 530 of the display apparatus 500. The response signal transmitted thereto is transmitted to the device management module 120 of the content providing server 100 through the communication network 300.
