The present invention relates to a broadcast system, and more particularly, to a wireless broadcast system provided in a home.

Recently, the field of interest in the development trend of the information communication network is the construction of the communication network in the home. This is meaningful in that it is the area that makes the final blood flow of the high speed communication network with the expansion of the national high speed communication network base and the establishment of the network in the enterprise. As one of such home network construction, digital television is widely used. That is, the digital television may not only provide a broadcast program but may be connected to a network to provide various information and contents to the user. In addition, the user may transmit or receive various types of information using the bidirectional communication function of the digital television.

On the other hand, according to the development of wireless information communication network, users can use the Internet as well as communication through mobile phones, and recently, the distribution of mobile phones for digital multimedia broadcasting (hereinafter, simply referred to as 'DMB phones') In some cases, you can watch broadcast programs through your mobile phone. Therefore, the user can watch the broadcast program he / she wants at any time using the DMB phone not only through a television provided at home, but also outdoors, in a bus, and a subway.

As described above, the user may watch a broadcast program in the home as well as outdoors using the DMB phone.

However, the DMB phone is basically a communication-oriented medium, and it is inconvenient for the user to use the DMB phone for watching a broadcast program.

For example, if a user is watching a broadcast program through a DMB phone and a call comes in, the DMB phone switches the reception of the broadcast program to standby state and then activates a communication function. There is a problem that you cannot watch the program. This problem can be solved by adding a multitasking function to the DMB phone, but in this case, the terminal is expensive.

In addition, although the function of the rechargeable battery of the DMB phone is improved so that it can be used for a long time, the rechargeable battery can be easily discharged if the user watches a broadcast program through the DMB phone for several hours when at home. In addition, when a user who is watching a broadcast program through a DMB phone needs to go out in a hurry, there may be a problem that a user may not properly use the DMB phone due to a discharged rechargeable battery.

In addition, the user tends to prefer a small size because the user purchases the DMB phone for the purpose of carrying it on the go, and therefore, the user cannot watch a broadcast program for a long time through the small screen of the DMB phone. In other words, the DMB phone is a medium used by the user to soothe boredom while going out, which is inconvenient to use for a long time in a house.

In addition, the number of broadcast programs broadcast through television is increasing innumerably, such as over-the-air broadcasts, satellite broadcasts, and cable broadcasts, but broadcast programs broadcast through DMB phones are still broadcast programs broadcast through television. It is not able to keep up with the number of. Therefore, the user does not use the DMB phone at home except in special cases.

On the other hand, at least one or more televisions are generally provided in the home, but since TVs are large in size and weight, there is a problem in that a user cannot watch a broadcast program while moving. That is, even a user at home may not be able to sit in front of a television and watch a broadcast program. In this case, the user may only listen to the contents while turning the volume up. For example, if the user wants to go to the bathroom while watching television, to work in the garden, or to work in a room without a television, the user may not be able to watch television as described above. .
