2 is a diagram for comparing a channel information transmission method and a general channel information transmission method according to an embodiment of the present invention.

2 (a) illustrates a general channel information transmission method, and FIG. 2 (b) illustrates a channel information transmission method according to the present invention.

Referring to FIG. 2A, the service server generates main channel information, programming information for the main channel, subchannel information, and subchannel programming information, and registers the subchannel information in the service server DB. Here, the main channel and the subchannel refer to the same real-time TV service or a channel in which a channel providing contents is divided into user terminals. That is, the main channel and the subchannel may provide the same real-time TV service to the user based on the same programming information, or may be a channel providing the same content to the user, or a type of data transmitted (e.g., resolution ) Means different channels. For example, if channel 11, which provides real-time TV service or content for A in IPTV, is defined as a main channel, channel 11, which provides real-time TV service / content for the same A to the mobile device, is defined as a subchannel can do. In addition, the program information means a program schedule table displayed on a channel-by-channel basis to provide viewing comfort for viewers. For example, EPG (Electronic Program Guide) used in D-TV or DMB broadcasting, And Electronic Service Guide (ESG).

The service server which registers the main channel information and the subchannel information transmits the main channel information and the subchannel information registered in a broadcast, multicast or unicast manner to the user terminal as shown in Tables 1 and 2 below, To each channel independently. At the same time, the service server independently transmits the program information for the main channel and the program information for the sub channel to the user terminal.

Table 1 illustrates a 'LinearTVDiscovery' record showing main channel information.

Service Identifier 1111 Service Id 1111 RegionCode 12 Service Visibility Y Streaming Type RTP Service Type (TypeOfService) 0x01 Service Name (ServiceName) A ServiceDescription A channel Service Genre (ServiceGenre) Terrestrial

Table 2 illustrates a 'LinearTVDiscovery' record indicating subchannel information.

Service Identifier 2222 Service Id 2222 RegionCode 12 Service Visibility Y Streaming Type RTP Service Type (TypeOfService) 0x01 Service Name (ServiceName) A ServiceDescription A channel Service Genre (ServiceGenre) Terrestrial

That is, as shown in Table 1 and Table 2, the service server generates separate channel information for the primary and secondary channels served by different terminals, and separately transmits the primary channel information and the secondary channel information. Accordingly, the user terminal receives both the main channel information and the subchannel information irrespective of the terminal using the main channel service or the terminal using the subchannel service. Thus, the capacity of the service server and the traffic of wired and wireless resources are increased, and the configuration of the transmitting and receiving apparatus can be complicated.

On the other hand, referring to FIG. 2 (b), the service server generates main channel information including subchannel information and programming information for a main channel, and registers the main channel information and the main channel information. After that, the service server registers the main channel information including the subchannel information and the combination information for the main channel. The service server notifies the user terminal of the main channel information including the subchannel information registered in broadcast, multicast, or unicast Only channel information is transmitted. At the same time, the service server transmits only the program information for the main channel to the user terminal.

Table 3 illustrates a 'LinearTVDiscovery' record showing main channel information including subchannel information.

Service Identifier 1111 Service Id 1111 RegionCode 12 Service Visibility Y Streaming Type RTP Service Type (TypeOfService) 0x01 Service Name (ServiceName) A ServiceDescription A channel Service Genre (ServiceGenre) Terrestrial The subchannel service ID (Service ID) 2222 Subchannel multicast IP (Multicast IP) xxxx.xxxx.x Subchannel Multicast Port 1 2 3 4 5

Referring to Table 3, the service server defines subchannel information, i.e., a service ID, a multicast IP, and a multicast port in a 'LinearTVDiscovery' record, and transmits the subchannel information to the user terminal. The 'LinearTVDiscovery' record according to the present invention may include at least one of the fields shown in Table 3, and a new field not illustrated in Table 3 may be added . For example, it may further include a main channel multicast IP and a main channel multicast port field, and may include a portal URL (Portal Uniform Resource Locator), a purchase information URL (Purchase Information URL) (Eg, Max bit rate, Audio coding, Video coding, Service availability, Multiplex mode, Additional linear TV discovery, Forward error correction Forward Error Correction (FEC), an IP Multicast Address, an IP Multicast Source, a Unicast URL field, and the like may be further included.

Upon receiving the main channel information including the subchannel information, the UE checks whether there is subchannel information at the time of parsing the channel information. If the subchannel information exists, the terminal checks the multicast IP and port of the subchannel of the corresponding channel And the sub-channel combination information refers to the combination information corresponding to the service ID (service ID) of the main channel. That is, as described above, the subchannel is the same channel as the main channel and provides the same real-time TV service or contents. Therefore, in the case of the terminal using the subchannel service, The same can be used.

In this manner, the subchannel information is combined with the main channel information and transmitted to the user terminal, and the scheduling information for the subchannel is not transmitted to the user terminal, thereby reducing the overhead of radio resource use.

3 is a diagram illustrating a channel information transmission method according to an embodiment of the present invention.

Hereinafter, for convenience of description, the first terminal assumes a terminal receiving a main channel service, and the second terminal assumes a terminal receiving a subchannel service.

Referring to FIG. 3, the service server generates channel information and registers the generated channel information in the DB of the service server (S301). That is, the service server generates the main channel information by adding the attribute information of the subchannel to the extended descriptor of the main channel information. Here, the subchannel attribute information may include a subchannel service ID (Service ID), a subchannel multicast IP (multicast IP), and a subchannel multicast port.

The service server registers the main channel combination information in the DB of the service server (S303). At this time, the service server does not register the program information separately for the subchannel.

The service server, which has registered the main channel information and the main channel combination information, transmits the main channel information and the main channel combination information to the first terminal and the second terminal in a broadcast, multicast or unicast manner (S305).

First, the operation of the first terminal will be described. The first terminal receiving the main channel information and the main channel programming information from the service server parses the received main channel information (S307), and extracts main channel line- (S309). Here, the channel lineup information is information obtained by arranging channel related information such as a channel number, a channel name, a channel logo, and a channel genre.

Then, the first terminal parses the main channel combination information using the main channel service ID included in the main channel information (S311).

The first terminal parsing the main channel configuration information outputs the main channel information and the main channel configuration information to the screen of the first terminal (S313), and when the channel is input by the user, (S315). At this time, the first terminal can receive the main channel image using the main channel multicast IP and the main channel multicast port.

The second terminal parses the received main channel information (S317), and determines whether subchannel information is included in the main channel information (S319). That is, the second UE determines whether the extended descriptor of the main channel information includes the attribute information of the subchannel. Here, the attribute information for the subchannel may include a subchannel service ID, a subchannel multicast IP, and a subchannel multicast port field.

If the main channel information includes attribute information on the subchannel, the second terminal generates channel lineup information using the subchannel multicast IP and / or the subchannel multicast port (S321). Next, the second terminal parses the main channel combination information using the main channel service ID included in the main channel information (S323).

The second terminal parses the main channel configuration information and outputs the subchannel information and the main channel configuration information to the screen of the second terminal (S313). When a channel is input by the user, (S315). At this time, the second terminal can receive the subchannel image using the subchannel multicast IP and the subchannel multicast port.
