Hereinafter, a broadcast system to which the present invention is applied will be schematically described with reference to FIG. The IPTV broadcasting system 1 may include various local and network elements, but only the parts necessary for explanation will be shown here.

1, a broadcasting system 1 includes a home broadcasting system 2 and a broadcasting center 3. In FIG.

The home broadcasting system 2 refers to a system for processing and displaying broadcast data (for example, multicast data) received from the broadcasting center 3.

In this specification, the home broadcasting system 2 is limited to the home, but this is merely an example, and may include a system for providing a broadcasting service at a small scale such as a company or a public place.

The home broadcasting system 2 may include a set-top box 100, a router 200, and a display device 300.

The wired / wireless router 200 is connected to various devices using the IP network including the in-house set top box 100. The wired / wireless router 200 can be connected to a corresponding device by wire or wirelessly.

The set-top box 100 receives broadcast traffic (e.g., multicast data) received from a broadcast center and provides the broadcast traffic to the display device 300. The specific components of the set-top box 100 will be described later with reference to FIG. 3 and will not be described here.

The set-top box 100 may calculate packet drop information of broadcast traffic that is lost. A specific method will be described later.

The set top box 100 transmits the packet drop information of the calculated broadcast traffic to the broadcasting center 3.

In this way, the set-top box 100 can calculate packet drop information that is input to the set-top box 100.

Also, the set-top box 100 may monitor the packet flow of the router 200 to determine packet drop information lost in the router 200. [ Although the set-top box 100 can determine packet drop information lost in the wireless router 200 using Simple Network Management Protocol (SNMP), it is not limited thereto.

The set-top box 100 may transmit the packet drop information of the broadcast traffic, which is calculated, to the broadcast center 3, as well as the packet drop information lost in the wireless router 200.

In this case, the broadcasting center 3 can grasp the packet drop information between the set-top box 100 and the wired / wireless router 300.

On the other hand, the broadcasting center 3 receives packet drop information lost in the home broadcasting system 2, and when the packet drop information does not reach a predetermined level, the broadcasting center 3 identifies the corresponding set-top box 100, (2).

The broadcasting center 3 includes an IPTV quality collection server 400 and an IPTV notification system 500. The broadcast center 3 may include various components than those shown in the figure, but only the components defined in the present invention are shown.

The IPTV quality collection server 400 is a server for collecting data necessary for an IPTV service. The IPTV quality collection server 400 may collect data related to the IPTV service from the home broadcasting system 2.

The IPTV announcement system 500 provides information necessary for the home broadcasting system 2.

The IPTV announcement system 500 can provide a self management service so that an IPTV user can solve the problem of the home broadcast system 2 directly. In particular, it is possible to transmit to the home broadcasting system 2 a message to solve the problem of wiring in connection with the above-described packet drop information.

The transmitted guidance message may be displayed on the display device 300.

2 is a diagram showing that a notification message indicating a wiring problem is displayed on the display device.

Referring to FIG. 2, the display device 300 can receive and display the displayed phrase from the set-top box 100.

The broadcasting center 3 can analyze the packet drop information received from the home broadcasting system 2 and judge whether the dropped packet is lost at the STB 100 or lost at the STB 200. [

In this case, the broadcasting center 3 can provide the display device 300 with a phrase as shown.

Hereinafter, the components of the set-top box 100 will be described.

3, the set-top box 100 includes a network interface unit 110, a TV interface unit 120, a remote control receiving unit 130, a decoding unit 140, a downgrade unit 150, A processing unit 160 and a control unit 170.

The network interface unit 110 transmits or receives data via the Internet according to a communication protocol including at least one of TCP / IP, UDP / IP, and IGMPv2.

The TV interface unit 120 transmits the first or second broadcast content to the TV or transmits various information and receives the broadcast content from the TV 300 and stores the broadcast content in a storage unit Can be stored.

The remote control receiving unit 130 receives a control command according to the remote control operation of the client.

The decoding unit 140 decomposes the TS packet first broadcast content received through the network interface unit 110 into PES packet first broadcast content, and then decodes the TS packet according to a predetermined standard.

The downgrading unit 150 downgrades the first broadcast content to the second broadcast content under the control of the controller 170 and outputs the downgraded second broadcast content. The downgrade of the downgrading unit 150 reduces the resolution and the size of the broadcast content.

The signal processing unit 160 processes the first broadcast content or the second broadcast content downgraded by the downgrade unit 150 so that the second broadcast content can be displayed on the screen of the TV 150. [

The STB control unit 170 controls and manages the entire system and includes a network interface unit 110, a TV interface unit 120, a remote control receiving unit 130, a decoding unit 140, a downgrade unit 150, And controls each of the signal processing units 160.

The STB control unit 170 performs a control command of the client received through the remote control receiving unit 130. [

Upon receiving the first broadcast content through the network interface unit 110, the controller 170 decodes the first broadcast content through the decoding unit 140 and determines the type of the broadcast content requested by the client. The signal processing unit 160 processes the first broadcast content and controls the processed first broadcast content to be transmitted to the TV 300 through the TV interface unit 120. [

On the other hand, if the type of the broadcast content is standard image quality, the control unit 170 downgrades the decoded first broadcast content through the downgrade unit 150, processes the signal through the signal processing unit 160, And controls the content to be transmitted to the TV 300 through the TV interface unit 120.

Here, the first broadcast content may be decoded after being down-grained.

The TV 300 is an Internet Protocol TV (IPTV). The TV 300 is interworked with the set-top box 100 and serves broadcast contents such as moving pictures and various useful information through the Internet protocol (IP) And a communication terminal.

The TV 300 displays the first or second broadcasting contents received from the set-top box 100, displays various useful information, and transmits the broadcasting contents (terrestrial broadcasting contents) of the channel according to the remote control operation of the client to the antenna And displays it.

On the other hand, the set-top box 100 can calculate the first packet drop information of the broadcast traffic received from the broadcasting center 3.

Specifically, the set-top box 100 can calculate a packet drop through a packet sequence number of an RTP (Real Time Transport Protocol) of a packet to be transmitted. (First Packet Drop Information) For example, When the packet is marked as "1, 2, 5, 7, 10" and transmitted, it can be calculated that the packet of "3, 4, 6, 8, 9"

In addition, the set-top box 100 can also calculate packet drop information of a wired / wireless router (e.g., home gateway).

Specifically, the set-top box 100 periodically transmits an SNMP command to the wired / wireless router to receive and calculate packet drop information. (Second packet drop information)

SNMP is a protocol for managing network equipment. It is divided into a management manager (for example, a device transmitting a management message) and an agent (for example, a device responding to a management request message) . At this time, ports UDP 161 and 162 can be used.

The set-top box 100 can transmit the above-described packet drop information to the broadcasting center 3. In this case, the broadcasting center 3 can determine the loss of the broadcast traffic by referring to the first packet drop information and / or the second packet drop information.

The IPTV quality collection server 400 of the broadcasting center 3 can judge that the broadcast data is lost in the wiring when the first packet drop information exceeds the preset reference value. For example, it can be assumed that the reference value of the broadcasting center 3 is as follows.

Reference value = data received by the set-top box / data transmitted to the set-top box

At this time, when the reference value is 0.7 or less, it can be a reference value that the broadcasting center 3 grasps as a wiring problem. However, this is only an example and the packet drop information of the home broadcasting system 2 can be calculated by various criteria.

In particular, the broadcasting center 3 uses the second packet drop information obtained by monitoring the set-top box 100 by the set-top box 100 and the first packet drop information input to the set-top box 100, Information can be accurately judged.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
