The present invention relates to a reception setting method of a satellite broadcasting receiver (DSR-STB), and more particularly, to a reception setting method of a satellite broadcasting receiver based on an LNB index.

In general, satellite broadcasting receives the broadcast signal transmitted through the uplink from the earth station on the earth from the satellite located on the geostationary orbit, and then amplifies it from the transponder (TP) and transmits it through the downlink again. Is to make it available to the receiver.

In order to receive satellite broadcasting in each home on the ground, the antenna is installed outdoors and receives the SHF band radio signal from the satellite, and the low frequency amplification signal of the SHF frequency band (4 ~ 12GHz) received from the antenna is mid-frequency of 1GHz band. Low Noise Block Down Converter (LBN), which is converted into (IF) and transmitted indoors via coaxial cable, satellite set top box (hereinafter referred to as 'satellite broadcast receiver') and satellite set top box installed indoors Requires a television connected to the STB.

Normally, a satellite launched on a geostationary track for satellite broadcasting has a plurality of repeaters. For example, the KOREA SAT2 includes three broadcast repeaters and 12 communication repeaters, and the Mugunghwa satellite 3 (KOREA SAT3) is equipped with 6 broadcasting repeaters and 24 communication repeaters. In addition, satellites use various types of polarization for efficient use of radio waves, for example, left circular circular polarization (LHCP), vertical polarization or horizontal polarization.

The outdoor antenna needs to adjust the elevation angle and azimuth angle according to the satellite and region to be received, and the outdoor low noise frequency converter is integrated with the feed horn located in front of the dish antenna reflector. In addition, the low-noise frequency converter can select either vertical or horizontal polarization according to the voltage of the power supplied from the satellite broadcasting receiver, and high and low bands according to the 22KHz tone signal.

As described above, since satellites have a plurality of repeaters (TPs) and polarization schemes vary, it is necessary to set reception as shown in FIGS. 6 and 7 in order to watch satellite broadcasts. In general, the reception setting is performed by a procedure such as satellite setting (or TP setting), LNB setting, tuner setting, disec switch setting, and the like, and is set in a menu manner by remote control operation as shown in FIGS. 6 and 7.

On the other hand, two or more low-noise frequency converters may be installed to receive broadcast signals from multiple satellites, and satellite broadcast receivers are advanced to simultaneously watch multiple channels or simultaneously record different channels while watching one channel. More than one tuner can be installed in one satellite receiver.

However, the conventional digital broadcast receiver has a limitation in using two tuners according to the number of LNBs receiving each satellite signal. For example, by selecting polarization, high band, and low band within one LNB, only a specific frequency is accepted, so that both tuners receive only a specific frequency within one satellite signal. Will be tuned.

In accordance with these limitations, the digital broadcast receiver tunes the LNB signal coming from one signal line in a loop-through format where the two tuners share, and independently tunes different LNB signals from the two signal lines on each tuner. The user can set the separate form in the menu. At this time, the digital broadcast receiver in which the satellite signal connection type for the two tuners is set, when the LNB signals received through the two signal lines are the same, the channel is searched by two tuners or the channel found by one tuner is transferred to another channel. Provides the ability to copy.

End users who use a digital broadcast receiver with two tuners are difficult to understand the limitations on the tuner and do not use the product with two tuners properly if the two tuners are set to loopthrough / separated. There is a problem.

4 is a first embodiment showing a conventional reception setting concept in a satellite broadcasting receiver. As shown in FIG. 4, the conventional first method uses a method of setting an LNB and a TUNER based on a satellite. In this case, when setting two or more tuners, a new satellite must be created by copying satellites by the number of tuners. In other words, they must actually create the same satellite or radiation satellite. In addition, according to the first method of the related art, TP information of satellites may be added or removed over time. In this case, a problem arises in that the copied satellite is also changed.

5 is a second embodiment showing a conventional reception setting concept in a satellite broadcasting receiver. As shown in FIG. 5, the conventional second scheme is a method for setting two tuners under satellite information. The conventional second scheme may solve the problem of the conventional first scheme, but if a tuner is added, the data structure may be modified. The problem arises of making changes and modifying the user interface (UI).

As such, the reason for viewing the same satellite by using multiple tuners is that the tuner can only lock one repeater (TP) because of the characteristics of the tuner, so that when the channel is recorded on different repeaters (TP) of the same satellite, You may not be able to record channels. There is a loop through method, but this also does not control the LNB, there is a problem that can not record or view the channel of other polarization (polarization)

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a reception setting method using the LNB index of the satellite broadcast receiver to set the reception of the satellite broadcast receiver based on the LNB index (index). It is.

In order to achieve the above object, the method of the present invention, in the satellite broadcasting receiver having at least two or more tuners in the method for setting the satellite, LNB and tuner so that the user can watch the desired broadcast channel, low noise frequency Since satellites are set for each low noise frequency converter (LNB) by setting satellites and tuners based on the converter (LNB), there is no need to copy new satellites, and since only one satellite information is stored for each satellite, It does not need to be modified, and even if a tuner is added in the future STB development, there is no need to change the user interface (UI) or data structure.

The reception setting method may include setting a virtual LNB index; Selecting a satellite number for each LNB index; Setting the LNB information; And sequentially setting tuner information, wherein the satellite information is satellite name, polarization method, frequency of local oscillator, SR, etc., the LNB information is local oscillation frequency, LNB POWER (13 / 18V), 22KHz tone And so on.

For example, a plurality of antennas or LNB outputs may be connected by a diesec switch to receive a single tuner. One LNB output can be connected to multiple tuners using multiple switches or can be connected separately.

The satellite broadcast receiver 30 recovers the digital broadcast program of the MPEG2 transport stream received through the antenna 10 and the LNB 20 to the original video and audio signals, and then processes the video and audio signals. An audio signal is output through a television (not shown) so that a user can watch a desired digital broadcast program.
