Hereinafter, the integrated digital signal processing system 1000 according to an embodiment of the present application will be referred to as the present system 1000 for convenience of description.

1 to 3 , the system 1000 may include a plurality of antennas 1 ′, an integrated digital signal processing device 100 , a broadcasting relay center 15 , and each household 2 .

Here, the integrated digital signal processing apparatus 100 may refer to the integrated digital signal processing apparatus 100 according to an embodiment of the present application. Hereinafter, the integrated digital signal processing apparatus 100 according to an embodiment of the present application will be referred to as the present apparatus 100 for convenience of description.

The apparatus 100 may be expressed differently as a digital signal integrator, a digital broadcast signal integrator, and a digital channel processor.

In the example shown in FIG. 1 , the apparatus 100 is illustrated as a configuration separate from the broadcast relay center 15 , but this is only an example and is not limited thereto. As another example, the apparatus 100 is It may be a device included in the broadcasting relay center 15 .

The apparatus 100 may include an input unit 110 , a generation unit 120 , and a control unit 130 .

The input unit 110 may receive a plurality of reception signals received through the plurality of antennas 1 ′. Here, the plurality of antennas 1 ′ may be expressed differently as a plurality of reception antennas and the like.

The plurality of antennas 1' is an FM antenna (circular polarization broadcasting receiving antenna), DMB antenna (T-DMB antenna, vertical polarizing broadcasting receiving antenna), terrestrial antenna, HD antenna, UHD antenna (UHF TV antenna, flat polarization broadcasting receiving antenna) antenna) and satellite antennas. Here, the satellite antenna may include a KOREASAT 5 antenna, a KOREASAT 6 antenna, a skylife antenna, and the like.

In one example of the present application, as the plurality of antennas 1', antennas related to FM, DMB, HD, UHD, satellite, etc. have been exemplified to be included, but the present disclosure is not limited thereto, and various antennas capable of receiving broadcast signals may be included. have.

Accordingly, the input unit 110 may receive a broadcast signal (a broadcast reception signal) as a plurality of reception signals from the plurality of antennas 1 ′. That is, the reception signal received from the antenna may be expressed differently as a broadcast signal, a broadcast reception signal, or the like. The received signal is, for example, FM signal (FM broadcast signal), DMB signal (DMB broadcast signal), terrestrial signal (terrestrial broadcast signal), HD signal (HD broadcast signal), UHD signal (UHD broadcast signal), satellite signal (satellite broadcast signal) signal) and the like.

As an example, the frequency range for each type of a plurality of reception signals (broadcast signals) received from the plurality of antennas 1' (ie, FM, DMB, HD, UHD, satellite broadcast (especially educational broadcast, KBS1, etc.) is shown in Fig. It may be as shown in 3 .

The input unit 110 may include a plurality of input ports provided in a number corresponding to the number of the plurality of antennas 1 ′.

For example, the number of the plurality of antennas 1 ′ may be six as shown in FIG. 2 , and accordingly, the number of the plurality of input ports may be six. For example, the plurality of input ports may include an input 1 port to an input 6 port. The input port may be expressed differently as an input terminal or the like.

In the above-described example of the present application, the number of the plurality of antennas 1 ′ and the number of the plurality of input ports have been exemplified as six, but this is only an example for helping understanding of the present application, and is not limited thereto. The number of antennas 1' and the number of the plurality of input ports may be variously set.

Exemplarily, the input port 1 is an input port corresponding to the first antenna (eg, an FM antenna), and may receive an FM signal as a reception signal (first reception signal) received through the first antenna. The input 2 port is an input port corresponding to a second antenna (eg, a DMB antenna), and may receive a DMB signal as a reception signal (second reception signal) received through the second antenna.

The input 3 port is an input port corresponding to a third antenna (eg, UHD antenna), and may receive a UHD signal as a reception signal (third reception signal) received through the third antenna. The input 4 port is an input port corresponding to a fourth antenna (eg, an HD antenna), and may receive an HD signal as a reception signal (fourth reception signal) received through the fourth antenna.

The input 5 port is an input port corresponding to the fifth antenna (eg, Mugunghwa No. 5 antenna), and may receive a satellite signal as a reception signal (fifth reception signal) received through the fifth antenna. The input 6 port is an input port corresponding to the sixth antenna (eg, Mugunghwa No. 6 antenna), and may receive a satellite signal as a reception signal (the sixth reception signal) received through the sixth antenna.

In this case, for example, the third antenna may mean an antenna provided (installed) at the Gwanaksan transmission station, and the fourth antenna may mean an antenna provided at the Namsan transmission station (installation).

In the above description, an example of a reception signal received through each input port is merely an example for helping understanding of the present application, and is not limited thereto, and various broadcast signals may be received.

According to this, the plurality of antennas 1 ′ considered in the present system 1000 to the present apparatus 100 includes at least some antennas among the antennas provided in each of the plurality of transmission stations provided in different regions (positions). can do. Here, the transmission station may be expressed differently as a relay station, a transmission station, and the like.

The generation unit 120 may generate an output signal in consideration of reception signals of some selected channels among all channels of the plurality of reception signals input from the input unit 110 . To this end, the generation unit 120 may include a selection unit 121 , a rearrangement unit 122 , a deletion unit 123 , and an adjustment unit 124 .

The selector 121 may selectively select (select) some channels among all channels of the plurality of received signals input to the input unit 110 . In this case, some channels selected by the selection unit 121 may include channels corresponding to each of the plurality of broadcasting station types related to the plurality of received signals input to the input unit 110 one-to-one. The selection unit 121 may be expressed differently as a selection unit or the like.

Here, the broadcasting station type may mean a type related to a broadcasting station name, such as KBS1, KBS2, SBS, MBC, OBS, Educational Broadcasting (EBS), JTBC, TVN, and the like.

For example, when there are five types of a plurality of broadcasting stations related to a plurality of received signals, the selector 121 may select five channels corresponding to each of the five broadcasting station types as a part of all channels. That is, each of the partial channels may mean a channel corresponding to each of a plurality of broadcasting station types related to a plurality of received signals.

That is, in selecting a part of all channels, the selection unit 121 includes only one channel related thereto for each type of a plurality of broadcasting stations (in other words, one channel matched thereto for each type of a plurality of broadcasting stations). only), some channels can be selected.

When a plurality of related channels related to any one of the plurality of broadcast station types exist in all channels, the selection unit 121 is based on a result of analyzing the reception sensitivity of the received signal corresponding to each of the plurality of related channels. Some channels can be selected. The selector 121 may recognize a channel having the largest value of the reception sensitivity of the received signal among the plurality of related channels as a channel corresponding to any one of the above-mentioned broadcasting station types one-to-one, and select some channels. This can be more easily understood with reference to FIG. 4 .

4 is a view for explaining an example of a process of selecting some channels by the selector of the integrated digital signal processing apparatus 100 in the integrated digital signal processing system 1000 according to an embodiment of the present application.

Referring to FIG. 4 , as an example, it is assumed that the plurality of antennas 1 ′ considered in the present apparatus 100 is two, and the two antennas are a third antenna and a fourth antenna, respectively. In this case, it is assumed that the third antenna among the plurality of antennas 1' is the antenna provided at the Gwanaksan transmission station (transmission station), and the fourth antenna is the antenna provided at the Namsan transmission station.

Accordingly, the input unit 110 receives a terrestrial signal (broadcast signal) as a third reception signal from the third antenna of the Gwanaksan transmission station through the input 3 port, and receives a fourth reception from the fourth antenna of the Namsan transmission station through the input 4 port. Assume that a terrestrial signal (broadcast signal) is received as a signal.

In this case, the channels of the third reception signal may include channels 15, 17, 18, 14, and 16, and the channels of the fourth reception signal may include channels 22, 45, 46, 50, and 44. According to this, the total channels of the plurality of received signals considered by the apparatus 100 are all channels related to the received signal including the third received signal and the fourth received signal, and a total of 10 channels (ie, channels 15 and 17). , 18, 14, 16, 22, 45, 46, 50, 44).

In addition, the plurality of broadcast station types associated with the plurality of received signals (ie, the third received signal and the fourth received signal) include 1TV (which may mean KBS1) as the first broadcast station type and 2TV as the second broadcast station type (which may mean KBS2), Education Broadcasting (EBS) as the third broadcasting station type, MBC as the fourth broadcasting station type, and SBS as the fifth broadcasting station type.

Accordingly, among all channels, channels 15 and 22 may be channels related to the first broadcasting station type (1TV), and channels 17 and 45 may be channels related to the second broadcasting station type (2TV). Also, channels 18 and 46 among all channels may be channels related to a third broadcasting station type (EBS).

In other words, channels 15 and 22 may exist as a plurality of related channels related to the first broadcasting station type (1TV), and channels 17 and 45 may exist as a plurality of related channels related to the second broadcasting station type (2TV) in the entire channel. . In addition, channels 18 and 46 may exist as a plurality of related channels related to the third broadcasting station type (EBS) in all channels.

That is, in all channels of the plurality of received signals, with respect to a plurality of broadcasting station types related to the plurality of received signals, for example, channels 15 and 22 as a plurality of related channels related to the first broadcasting station type exist, There may be a plurality of related channels associated with one broadcasting station type.

As such, when a plurality of related channels related to any one broadcasting station type exist in all channels, the selection unit 121 selects a channel in which the reception sensitivity of the received signal corresponding to each of the plurality of related channels appears as a larger value. Some channels can be selected.

For example, with respect to channels 15 and 22, which are a plurality of related channels related to the first broadcasting station type (1TV), the selector 121 may select a reception signal corresponding to channel 15 (ie, 1 TV broadcasting signal received from a third antenna). The reception sensitivity of the corresponding reception signal) may be compared with the reception sensitivity of the reception signal corresponding to the channel 22 (ie, the reception signal corresponding to the 2TV broadcast signal received from the fourth antenna).

As a result of the comparison of the reception sensitivities (the result of comparison between the reception sensitivity values), when the reception sensitivity of the reception signal corresponding to the channel 22 is greater than that of the channel 15, the selection unit 121 receives one of the two channels 15 and 22 Channel 22, which is a channel with a larger sensitivity value, can be selectively selected.

Similarly, as a result of the comparison of the reception sensitivity values of the reception signals corresponding to the channels 17 and 45 related to the second broadcasting station type (2TV), the reception sensitivity of the reception signal corresponding to the channel 45 is greater than that of the channel 17, The selector 121 may selectively select a channel 45, which is a channel having a larger reception sensitivity value, among the two channels 17 and 45 .

As a result of comparing the reception sensitivity values of the reception signals corresponding to the channels 18 and 46 related to the third broadcasting station type (EBS), when the reception sensitivity value of the reception signal corresponding to the channel 18 is greater than that of the channel 46, the selection unit Reference numeral 121 may selectively select a channel 18, which is a channel having a larger reception sensitivity value, among the two channels 18 and 46 .

As a result of comparing the reception sensitivity values of the reception signals corresponding to the channels 14 and 50 related to the fourth broadcasting station type (MBC), when the reception sensitivity value of the reception signal corresponding to the channel 14 is greater than that of the channel 50, the selection unit Reference numeral 121 may selectively select a channel 14, which is a channel having a larger reception sensitivity value, among the two channels 14 and 50 .

As a result of comparing the reception sensitivity values of the reception signals corresponding to the channels 16 and 44 related to the fifth broadcasting station type (SBS), when the reception sensitivity value of the reception signal corresponding to the channel 44 is greater than the value of the reception sensitivity of the reception signal corresponding to the channel 16, the selection unit Reference numeral 121 may selectively select a channel 44, which is a channel having a larger reception sensitivity value, among the two channels 16 and 44 .

Accordingly, the selector 121 may select the five channels 22 , 45 , 18 , 14 , and 44 as some of the total channels (10 channels). At this time, the five channels selected by the selection unit 121 include a plurality of broadcast station types (ie, 1TV, 2TV, EBS, MBC, and SBS) related to a plurality of reception signals (the third reception signal and the fourth reception signal). 5 broadcasting station types) may be a channel corresponding to each.

That is, for each of the plurality of broadcasting station types related to the plurality of received signals, the selector 121 selects only one channel related thereto (that is, only one channel related thereto), and selectively among all the channels. Some channels can be selected.

According to this, the selection unit 121 selects some channels among all channels so that, for each of the plurality of broadcast station types related to the plurality of received signals, there is only one channel of the received signal having the best reception sensitivity for each of the plurality of broadcast station types. can be optionally selected.

For example, the selector 121 may select a number of (as many) some channels corresponding to the number of types of a plurality of broadcasting stations related to a plurality of received signals among all channels. For example, in the example with reference to FIG. 4 , since the number of a plurality of broadcasting station types is 5, the selector 121 may select 5 channels as some of the 10 total channels.

However, the present invention is not limited thereto, and as an example, it is assumed that the device 100 has previously received selection channel information from the user. In this case, the selector 121 may select a channel corresponding to the selected channel information from among all channels as a partial channel based on the selected channel information previously input from the user.

For example, when KBS1, KBS2, and EBS are included in the selected channel information, the selection unit 121 based on the selected channel information, KBS1, KBS2, and three channels corresponding to the selected channel information among all channels. You can select EBS as some channel.

The rearrangement unit 122 may rearrange the received signals of some channels selected by the selection unit 121 based on (according to) channel information for each broadcasting station type defined in advance.

For example, it is assumed that the selector 121 selects five channels 22 , 45 , 18 , 14 , and 44 as some channels among all channels (10 channels). At this time, as shown in FIG. 4, channel 22 is a 1TV related channel, channel 45 is a 2TV related channel, channel 18 is an EBS related channel, channel 14 is an MBC related channel, and channel 44 is an SBS related channel. have. In this case, when channel 22 is a 1TV-related channel, it may mean that a channel through which a 1TV broadcast signal is received from the antenna (fourth antenna) of the Namsan transmission station is channel 22.

In this case, it is assumed that predefined channel information for each broadcasting station type includes information such as channel 9 for 1TV, channel 7 for 2TV, channel 13 for EBS, channel 11 for MBC, channel 5 for SBS, and the like.

In this case, since channel 22 among some channels selected by the selector 121 is a 1TV-related channel, the rearrangement unit 122 may rearrange channel 22 into channel 9 based on predefined channel information for each broadcasting station type. Similarly, in the case of channel 45, the rearrangement unit 122 rearranges it to channel 7 because it is a 2TV-related channel, and in the case of channel 18, to channel 13 because it is an EBS-related channel, and in the case of channel 14, to channel 11 because it is an MBC-related channel. rearranged, and in the case of channel 44, since it is an SBS-related channel, it can be rearranged into channel 5

Accordingly, the generation unit 120 may generate an output signal including the reception signals of some rearranged channels that have been rearranged by the rearrangement unit.

Illustratively, with respect to the five channels 22, 45, 18, 14, and 44 selected as some channels by the selection unit 121, channels 9, 7, 13, 11, and 5 are included in the rearranged partial channels. may be included.

Here, among some rearranged channels, channel 9 may mean a channel through which a 1TV broadcast signal is received as a received signal from the antenna (fourth antenna) of the Namsan transmission station. Among some rearranged channels, channel 7 may mean a channel through which a 2TV broadcast signal is received as a received signal from the antenna (fourth antenna) of the Namsan transmission station. In other words, among some rearranged channels, channel 7 may mean a channel through which a 2TV reception signal (broadcast signal) is output among reception signals received through the antenna (fourth antenna) of the Namsan transmission station.

Among some rearranged channels, channel 13 may mean a channel through which EBS broadcast signals are received as a received signal from the antenna (third antenna) of the Gwanaksan transmission station. Among some rearranged channels, channel 11 is a received signal from the antenna (third antenna) of the Gwanaksan transmission station and may mean a channel through which the MBC broadcast signal is received.

Among some rearranged channels, channel 5 is a received signal from the antenna (fourth antenna) of the Namsan transmission station and may mean a channel through which the SBS broadcast signal is received.

According to this, through the rearranged partial channels, a plurality of received signals (that is, different regions) input to the input unit 110 by the selective selection (selection) or rearrangement unit 122 by the selection unit 121 . Among the plurality of received signals received from the antennas of a plurality of transmission stations provided in , reception and provision of the best received signal (broadcast signal) for each type of broadcasting station (which has a high reception sensitivity value) may be provided.

The rearrangement unit 122 may generate one single channel number list based on the rearranged received signal (specifically, the rearranged received signal of some channels).

The deletion unit 123 may recognize and delete the remaining channels except for some channels selected by the selection unit 121 among all channels as overlapping channels.

According to the previous example, the deletion unit 123 selects some channels among all channels (10 channels, channels 15, 17, 18, 14, 16, 22, 45, 46, 50, 44) by the selection unit 121 . As the five channels 22, 45, 18, 14, and 44 are selected, the five channels 15, 17, 46, 50, and 16 may be deleted as the remaining channels except for some channels among all channels.

The adjusting unit 124 may adjust the level of the generated output signal based on the rearranged received signals of some channels, and through this, may provide the level-adjusted output signal.

Adjuster 124 may perform level adjustment of attenuating or amplifying the rearranged output signal of some channels (output signal corresponding to the rearranged partial channel) according to the strength of the input signal (input received signal), It is possible to provide a level-adjusted output signal to each generation (2).

The controller 130 may provide the output signal generated by the generator 120 . Specifically, the control unit 130 may transmit the output signal generated by the generator 120 to the broadcast relay center 15, and the broadcast relay center 15 transmits the output signal received from the control unit 130 to each generation ( 2) can be provided (transmission, transmission).

That is, the controller 130 may transmit the generated output signal to the broadcast relay center 15 , and may provide the generated output signal to each household 2 by the broadcast relay center 15 .

In particular, the control unit 130 may transmit, as an output signal, an output signal whose level is adjusted (ie, a level-adjusted output signal) to the broadcast relay center 15 , and each household (2) by the broadcast relay center 15 . can be provided as

The broadcasting relay center 15 may be, for example, a facility that is installed in a multi-family house such as an apartment or a row house, and enables the joint reception of terrestrial television broadcasting, satellite broadcasting, FM radio broadcasting, and general cable broadcasting (CATV). have. The broadcast relay center 15 may be, for example, a broadcast integrated reception system, but is not limited thereto.

Conventionally, several reception signals (broadcast signals) are received through an antenna and each is provided (transmitted) as an output signal, and in the process, each reception signal is simply provided in the form of integration without selection. Such a conventional method may have a problem in that, when the received signal is unstable, the output signal is also affected and the unstable output signal appears.

In contrast, in the present device 100 , the input unit 110 may receive a plurality of reception signals (several signals) from the plurality of antennas 1 ′. Thereafter, the selector 121 may selectively combine some of the plurality of input reception signals by selecting some channels among all channels of the plurality of input reception signals. Thereafter, the rearrangement unit 122 may rearrange the received signals of some selected channels. In other words, the rearrangement unit 122 may rearrange the output signal of a frequency corresponding to the reception signal of the partial channel based on the reception signal of the partial channel selected by the selection unit 121 . Through this, the generator 120 may generate an output signal based on the rearranged received signals of some channels.

Thereafter, the deletion unit 123 may delete the remaining channels (duplicate channels) except for some selected channels among all channels. Thereafter, the adjusting unit 124 may adjust the level of the generated output signal (the output signal generated based on the rearranged received signals of some channels), thereby providing the level adjustment output signal. In other words, the adjusting unit 124 may adjust the level of the output signal corresponding to the received signal of the selected partial channel. In this case, the adjusting unit 124 may amplify and/or attenuate the signal when the level is adjusted.

Thereafter, the control unit 130 may provide (transmit) an output signal (in particular, a level adjustment output signal) provided through the generation unit 120 to each generation 2 .

In other words, the device 100 receives several received signals and selectively combines them, then rearranges the frequency output signals, deletes the overlapping channels, and adjusts the level of the output signals (amplification and/or attenuation related adjustments) ) and transmit the level-adjusted output signal to each generation (2).

For example, when the input unit 110 receives (received) terrestrial signals (terrestrial broadcast signals, terrestrial reception signals) as a plurality of received signals through each of Namsan and Gwanggyo transmission stations, KBS1 and KBS2 may be arranged in different channel numbers (that is, the same channel signals are overlapped). That is, a plurality of channels (related channels) related to any one broadcasting station type may exist in all channels of a plurality of received signals. In other words, reception signals corresponding to a plurality of channels of at least some of all channels may be reception signals related to the same broadcasting station type.

On the other hand, for example, the OBS reception signal (broadcast signal) may be transmitted only from the Gwanggyo transmission station. In this case, one OBS-related channel may exist among all channels of the plurality of reception signals received by the input unit 110 .

After receiving the plurality of received signals from the input unit 110, the selection unit 121 may check and select the frequency with the best signal for each broadcast channel with respect to the plurality of received signals (this is the overlapping KBS1, In case of a single reception channel such as KBS2) and OBS, the signal can be used (selected). This can be equally applied to the satellite received signal, and as a result, the selector 121 receives the most from among the channels of the received signal from a plurality of received signals (ie, various signal sources) of various types such as satellite, terrestrial wave, and DMB for each broadcasting station. You can selectively select (select) a channel that shows a good signal.

In other words, when a plurality of related channels exist in relation to any one broadcasting station type among all channels of a plurality of input reception signals, the selection unit 121 has a frequency having the best signal among the plurality of related channels. The channel of the received signal (ie, the channel having the largest value of the reception sensitivity of the received signal) may be selected as a channel corresponding to any one broadcasting station type.

Exemplarily, when the total number of channels of the plurality of received signals is 10, and there are two related channels related to KBS1 as one of the broadcasting station types, the selection unit 121 has the highest reception sensitivity value among the two related channels. A large channel may be selected (selected) as a channel corresponding to one broadcasting station type (KBS1), and the selected corresponding channel may be referred to as a partial channel. If the total number of channels of the plurality of received signals is 10, and there are 3 related channels related to KBS2 as any one broadcasting station type, the selection unit 121 selects the channel having the highest reception sensitivity value among the 3 related channels. may be selected (selected) as a channel corresponding to any one broadcasting station type (KBS2), and the selected corresponding channel may be referred to as a partial channel.

On the other hand, the selection unit 121, among all channels of the plurality of input reception signals, when there is only one related channel, not a plurality, in relation to any other broadcasting station type (that is, when there is a single related channel), The single associated channel may be selected as a channel corresponding to any other broadcasting station type.

Illustratively, if the total number of channels of the plurality of received signals is 10, and the related channel related to OBS is one of them as any other broadcasting station type, the selection unit 121 may select one related channel (ie, OBS) related to the OBS. One single single related channel) is selected (selected) as a channel corresponding to any other broadcasting station type (OBS), and the selected corresponding channel may be referred to as a partial channel.

As such, the input unit 110 receives a plurality of antennas 1 ′ (or signal sources) for receiving various types of broadcast reception signals such as satellite signals (broadcast signals), terrestrial signals (broadcast signals), and DMB signals (broadcast signals). , source of a broadcast signal), the selection unit 121 selects the selected unit 121 for each (for each) type of a plurality of broadcast stations related to the plurality of received signals among all channels of the plurality of received signals. Channels that receive good broadcast signals can be selected (selected) one by one.

The generator 120 may generate an output signal by selectively combining received signals of some channels selected by the selector 121 among a plurality of received signals input from the input unit 110 .

In the process of generating the output signal, the rearrangement unit 122 in the generation unit 120 may rearrange the received signals of some channels selected by the selection unit 121 based on (according to) channel information for each predefined broadcasting station type. have.

That is, the rearrangement unit 122 may rearrange the received signals of some selected channels, for example, channel 9 for KBS1, channel 7 for KBS2, channel 11 for MBC, and the like. The generating unit 120 generates an output signal based on the rearranged received signals of some channels, and the control unit 130 provides the generated output signal to the broadcasting relay center 15 so that the generated output signal is transmitted to each household 2 ( can be sent).

In this case, when the rearrangement process by the rearranging unit 122 is performed, only one of the best received signals of the same broadcasting station may be used. That is, when the rearranging unit 122 performs the rearrangement process, only the channel having the largest reception sensitivity value is selectively selected by the selection unit 121, so that when a plurality of reception signals of the same broadcasting station are received (differently) In other words, for example, when there are a plurality of channels related to KBS1), rearrangement may be performed based on only one of the best signals. The rearrangement unit 122 may generate (configure) the rearranged signal (ie, the rearranged received signals of some channels) into one single channel number list.

That is, the rearrangement unit 122 may rearrange the output signal of a frequency corresponding to the received signal of the partial channel with respect to the reception signal of the partial channel selected by the selection unit 121 .

The deletion unit 123, in the plurality of received signals received from the plurality of antennas 1 ′, selects received signals (broadcast signals) of some channels including channels selected one by one for each broadcasting station by the selection unit 121 . It can be deleted by excluding the remaining received signals.

That is, the deletion unit 123 recognizes, among the plurality of received signals, the remaining channels except for some channels selected by the selector 121 as overlapping channels (duplicate channels), and the received signals of the remaining channels (remaining received signals). ) can be deleted.

In other words, the deletion unit 123 receives each broadcasting station received from a plurality of types of antennas 1' (ie, various signal sources) through which various types of reception signals (broadcast signals) such as satellite, HD, and UHD are received. If there are a plurality of received signals (broadcast signals) among the received signals (that is, a plurality of received signals input from the input unit), only one with the best reception sensitivity is left, and the rest of the received signals are excluded. and can be deleted.

The adjusting unit 124 receives the received signals from various signal sources (that is, a plurality of antennas), the received signals of some channels selected by the selecting unit 121 and rearranged by the rearranging unit 122 (that is, the received signals , with respect to an output signal corresponding to some rearranged channels), it is possible to perform level adjustment to attenuate or amplify according to the strength of the input signal (input received signal). That is, the adjusting unit 124 may adjust the level of the received signals of the rearranged partial channels (the output signals corresponding to the rearranged partial channels) to provide the level-adjusted level adjusted output signal.

Thereafter, the control unit 130 may provide the level adjustment output signal to the broadcasting relay center 15 in order to transmit the level adjustment output signal to each household 2 .

The apparatus 100 can reduce the number of cables and effectively improve the quality of broadcast signals compared to the prior art when installing a terrestrial antenna (receiving antenna), a satellite antenna, etc. to receive various types of broadcast signals.

The broadcast signal has a difference in signal quality depending on the antenna reception location. That is, depending on which area (place) the broadcast signal is received through an antenna installed (equipped), a difference occurs in the quality of the corresponding received signal (broadcast signal).

In consideration of this, the apparatus 100 determines that only the received signal having the highest quality for each broadcasting station among the received signals received through each antenna (that is, the reception sensitivity value is the largest value, which is determined to be a stable signal). By selectively selecting and combining only the received signal), it can be provided to each generation (2).

For example, the best signal quality is to receive broadcast signals related to KBS1, KBS2, and SBS through the antenna (for example, the third antenna) of the Gwanaksan transmission station, and broadcast signals related to MBC and EBS are transmitted through the antenna of the Namsan transmission station ( For example, when the signal quality is the best when received through the fourth antenna, the apparatus 100 transmits a signal for each broadcasting station among a plurality of received signals input through a plurality of input ports (input terminals) of the input unit 110 . An output signal can be generated by selecting (selecting) and combining (mixing) only the received signals with the highest quality.

That is, the device 100 is an example of a plurality of received signals input from the input unit 110 , and a received signal having the best signal quality related to a user-desired channel (a channel corresponding to selected channel information previously input from the user). It is possible to generate an output signal by selectively selecting (selection) only the selected received signals and combining (mixing) the selected received signals, and transmit them to each generation (2).

Illustratively, in the prior art, in Gyeonggi-do, it is necessary to add an OBS channel reception facility to receive OBS broadcast signals, and in the case of over-the-air broadcast signals (over-the-air channels), these broadcast signals are transmitted from the Namsan and Gwanaksan broadcast stations. In order to receive, at least two antennas must be installed. At this time, in order to wire the cables of each installed antenna to the disaster prevention room, material costs and labor costs increase.

On the other hand, the present application can provide a digital signal integrated processing device (this device, 100) that allows all signals that can be viewed over-the-air to be integrated and processed in one single device. By reducing the number of wiring cables, receiving channels can be selectively combined and provided (especially, channels of good quality reception signals can be combined and transmitted).

For example, when it is said that UHD signal is received at Gwanaksan transmission station and HD is received at Namsan transmission station. There is a problem in that a desired signal cannot be obtained because overlap occurs between signals. On the other hand, according to the present apparatus 100 (digital broadcast signal integration equipment) capable of integrating and processing all signals in one single device, it is possible to solve the problems of the conventional technology.

In other words, the present application proposes the present device 100 (digital signal integrator) capable of integrally processing all signals (received signals) that can be viewed over-the-air in one single device.

The apparatus 100 receives a plurality of received signals received from each antenna (ie, each of the plurality of antennas), and removes noise (ie, a selection unit, a deletion unit, etc.) for each signal characteristic of the plurality of received signals. By performing the process of removing noise through the control unit) and correcting the output signal (that is, adjusting the level of the output signal by the adjusting unit), the level-adjusted output signal can be provided to each generation (2). have.

The control unit 130 may transmit the level adjustment output signal to the broadcasting relay center 15 through a single cable (eg, one cable capable of digesting all bands such as an optical cable). Thereafter, the broadcasting relay center 15 may provide (transmit) the level adjustment output signal received from the apparatus 100 to each household (2, each household).

That is, the control unit 130 may provide the level adjustment output signal adjusted by the adjustment unit 124 to the broadcasting relay center 15 through a single cable, thereby providing it to each household 2 .

In other words, the selector 121 may select a channel corresponding to all the previously inputted channel information from among all channels as a receiving channel based on the selected channel information previously input from the user. Also, the device 100 may perform a function of changing a channel number (ie, a function of moving a frequency band) through a user's setting.

Here, the device 100 may receive pre-input selection channel information and setting information received from the user, for example, through a key input unit provided in one area of the device 100 .
