However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest.

The term used in the present invention is selected as a general term widely used as possible at present, but in certain cases there is also a term arbitrarily selected by the applicant, in which case the meaning is described in detail in the description of the invention, the name of a simple term It should be clear that the present invention is to be understood as a meaning of terms.

First, referring to the system layer of IPTV, as shown in FIG. 1, the IPTV system is composed of a content provider, a service provider, a network provider, and a user layer.

The content provider serves to provide content to a service provider and is also referred to as a content provider.

The service provider serves to provide a service to subscribers, collects various contents, and modifies a signal according to an IP environment and delivers it to a user. Here, the service provider may be a virtual existence.

The network provider connects a user and a service provider through an IP network. The transmission system may use various network networks such as an access network or a backbone network.

The user is provided with content and receives broadcasts. The user may include an IPTV, a set top box, a PC, or an IP phone.

Hereinafter, the concept of IPTV will be described in more detail.

2 shows a characteristic diagram of a system of IPTV.

Referring to FIG. 2, the system layer of the IPTV can be largely classified into a content provider, a service provider, and a user.

The content provider is also called a platform provider. These three groups have different roles. A content provider is a large group that provides all the services and data for a broadcast program.

In addition, the service provider transmits multimedia data, maintains the transmission network for stable reception of content to the customer, and the infrastructure and functions for network transmission to the content provider. To provide.

Consumer groups play a role in replaying incoming data using infrastructure such as xDSL and cable, and responding to user needs immediately.

Most are made up of companies that produce IPTV, which can be divided into IPTV, set top box, PC or IP phone. IP Phone does not have a direct relationship with IPTV, but in general, with IPTV, phone service can be provided together.

In detail, each group may be a content provider group, which may include a TV station and a radio station that make a broadcast program.

TV Station refers to existing terrestrial or cable stations, which can create and store programs that users can watch and transmit them digitally. In general, it is to be able to transmit in various broadcast forms.

Radio Station means a general radio station, and although there may be video channels at times, it can be said that most of them operate without a video channel.

VoD, AoD, and MoD services have different characteristics from TV stations and radio stations. In other words, in the case of VoD or AoD, it saves the broadcasting program, movie and music that I want and then plays it for viewing. For example, if there is a broadcast program that was not properly watched because there is no time to watch the current broadcast program, it is possible to connect to a site providing such a broadcast service and download the file or play it immediately.

AoD also offers the ability to record audio programs in real time or make it difficult to record audio programs.

MoD stands for Music On Demand and you can download and listen to the music you want. This seems to be similar to AoD, but the service is likely to be a record company or a record distributor may have expanded existing Web services.

The PF server is serviced by a company that manages all broadcasting and location information provided by the content provider. This service mainly contains broadcasting time or location information necessary for broadcasting and information that a user can access.

The EPG service is one of convenient services that allows a user to search a broadcast program by time zone and to grasp by channel. EPG service is a service that is used frequently enough that the type provided by TV Guide is representative, and the program is automatically installed and executed on the customer side.

ECG service has all functions that user can conveniently use contents information of content provider and location and access authority of access server. In short, it is an electronic content guide (EPG) that provides easy access to servers with content and details of the content.

Portal Server is a web service provided by each broadcasting station. The portal server is connected to a web server of a broadcasting company or a service provider. The role of Portal Server is to search or view the list of programs provided by each broadcaster or content providers that provide content services.

The service provider provides network stability and bandwidth so that multimedia data and broadcast data transmitted from a content provider are normally transmitted.

Service providers may also provide IPTV services using existing cable networks. In this case, equipments of a delivery network need to be changed.

In other words, network equipment that can transmit data in real time should be configured, and network should be configured in consideration of bandwidth to customer. These devices need to reduce bandwidth by processing large amounts of multimedia data using Multicast service, which is the basic network service of IPTV.

If bandwidth is not secured, Service Provider may retranscode multimedia broadcasting data from optical fiber network configuration or content provider and transform it into MPEG-4 or MPEG-7 in order to secure bandwidth. have.

Service Provider has to provide several services for this purpose. It is to provide size Network Management System (NMS), Dynamic Host Control Protocol (DHCP) and CDN services.

The NMS service allows the service provider to manage the delivery network and IPTV receivers of the customer, which can be transmitted to each customer. In other words, by using this service, it is possible to determine how much traffic is generated for a certain broadcast and in which region the bandwidth is insufficient.

DHCP service is used to automatically assign IP to customer's IPTV receiver and to inform the address of CDN server. DHCP services are also a good way to assign IP to PCs in the general network. The IPTV receiver should be sent an address that allows access to the licensed IPTV receiver so that the user can register during the initial connection.

CDN service is data provided by the service provider. When the IPTV receiver is powered on for the first time, the CDN service receives the CDN information from the service provider. This information contains the registration or authentication of the user of the IPTV provider and the aforementioned PF information.

A customer can have several types of IPTV receivers. If you have a regular TV, you can enjoy IPTV by renting an IPTV STB at a low price. A service provider can pay additional service costs at a low price and apply for an IP phone.

IPTV receiver basically has network interface to connect to network, and has internet protocol to receive and process data packet coming from network and play it on screen in case of multimedia data, and to control data packet when operating with remote controller It needs to be sent quickly to the server and get the information from the server and react.

That is, the IPTV receiver should operate to transmit the user's requirements in both directions while processing the multimedia data. Also, to use the service well, the remote control should be provided with buttons for IPTV.
