Modem, decoder and encoder. However, the broadcast apparatus 1000 of FIG. 3 employs a configuration different from that of FIG. 2 to display different advertisements or broadcast programs on the plurality of displays 401 to 404 installed in the screen door 400.

Specifically, the broadcast transmitting device 300 includes a plurality of distributors 311 and 312. Different broadcast programs modulated by the broadcast transmitting device 300 are supplied to the display through different distributors 311 and 312. For example, a shared advertisement program may be displayed on the displays 402 and 404 connected to the distributor 311, and an advertisement program specific to history may be displayed on the displays 401 and 403 connected to the distributor 3120. By using a plurality of distributors 311 and 312 and supplying different broadcast programs to the distributors 311 and 312, it is possible to display different broadcast programs on the plurality of displays 401 to 404, FIG. 2. The same effects as those of the broadcast apparatus described with reference to FIG. 4 may also be obtained. Additionally, the broadcast apparatus 1000 may include amplifiers 321 and 322 on a distribution path of a program.

In the broadcast apparatus of the present invention described with reference to FIGS. 2 and 3, the central server 100 and the broadcast transmitting device 300 have been described as being connected by a network 200 such as the Internet. The transmitting device may be connected to the central server by a coaxial cable.

4 is a block diagram illustrating an embodiment in which a central server and broadcasting stations 1000 of each history are connected by coaxial cables. As shown, the commercial program of the central server 100 is transmitted by the coaxial cable to the broadcast station 1000 by history via the distributor 110. Although one distributor 110 is illustrated in FIG. 4, an appropriate number may be used according to the number of broadcast apparatuses 1000 to be connected. In the broadcast apparatus 1000 of FIG. 4, since the commercial program from the central server 100 is transmitted as an analog signal, the broadcast transmission apparatus 300 merely serves as a relay for relaying the broadcast program of the central server. There is no need to install an additional device such as an MPEG decoder or a video encoder.

In the embodiment of Figure 4, the commercial program transmitted from the central server 100 is composed of a plurality of broadcast programs suitable for each history, these broadcast programs are composed of analog signals of different frequency bands.
