The present invention relates to a multiple output broadcast reception system, and more particularly, a plurality of set-top boxes, DVDs, VTRs, etc. are loaded in a rack form at a specific place, and a plurality of set-top boxes, DVDs, VTRs, etc. Independent control of set top boxes, DVDs, and VTRs, and multiple output broadcast receiving systems that enable remote control using a wireless remote control in a home or remote location where multiple set top boxes, DVDs, and VTRs are not installed. It is about.

Recently, with the rapid development of digital technologies such as digital image compression and digital modulation / demodulation, the standardization and commercialization of digital television (TV) broadcasting has been rapidly developed. In such a situation, a digital broadcast receiver such as a set-top box (STB) that receives digital television broadcasts uses a decoder provided in the receiver to select the original A / V (Audio / Video). After recovering the data, the data is transmitted to an A / V output device such as a general television, so that a user can selectively watch a broadcast program.

In recent years, most households have one television set in various places such as a home room, a living room, a study room, and the like. When the multiple TVs are connected to a single set-top box, each TV set includes satellite broadcasting, There is an advantage that you can watch cable broadcasting, digital terrestrial broadcasting.

However, as described above, the conventional method of connecting one set-top box to several TVs is not only difficult to transmit lossless signals from the set-top box to each room, but also requires additional line construction through track work in the home. Since the conditions must be satisfied, there was a problem in that the installation cost was increased and the installation process was difficult.

In addition, according to the conventional method of connecting one set-top box to several TVs, if you want to remotely control the set-top box from another place where the set-top box is not installed, an expensive RF (UHF) remote control transceiver is separately purchased. There was a problem that needs to be installed.

In addition, in the case of various set-top boxes, DVDs, and VTRs having independent functions, control is possible only by connecting directly to the TV in the form of an independent set, so that the user can only control a single TV directly connected to an independent set in a limited space. There was an uncomfortable problem that I had to watch.
