[Description of Comparative Example]
First, a general recorder tuner module (hereinafter simply referred to as “recorder module”) used in a recorder / set-top box and a general television receiver tuner module (hereinafter also referred to as “TV general-purpose module”). ) Will be described as a comparative example.

FIG. 1 is a schematic block diagram illustrating the configuration of a general recorder module.

  The RF signal amplified by the amplifier circuit 510 is input to the input node of the distribution circuit 520. The distribution circuit 520 distributes the signal input to the input node to the first to third output nodes and outputs the signal. The first output node of the distribution circuit 520 is input to the first satellite tuner IC 530. The signal at the second output node of the distribution circuit 520 is input to the second satellite tuner IC 540. Thereby, the RF signal of satellite broadcasting input to the input terminal 501 can be input to each of the plurality of tuner ICs for satellite broadcasting.

  Further, the third output node of distribution circuit 520 is connected to loop through terminal 502. Similarly, the third output node of distribution circuit 525 is connected to loop through terminal 504. Therefore, the RF signal of the satellite broadcast input to the input terminal 501 is output from the loop-through terminal 502. Similarly, an RF signal for terrestrial broadcasting input to the input terminal 503 is output from the loop-through terminal 504. As described above, by inputting these loop-through outputs to the tuner module of the television receiver, a television broadcast wave output from a single system wall terminal can be transmitted between the recorder / set-top box and the television receiver. Can be received by both.

  As described above, in the general recorder module 500, in order to provide the loop-through, the three distributors that distribute the input signal to the input node to the three output modes are required. Moreover, since it is necessary to ensure the space | interval between terminals, it exists in the tendency for size to enlarge.

FIG. 2 is a schematic block diagram illustrating the configuration of a general TV general-purpose module.
Referring to FIG. 2, TV general-purpose module 600 includes input terminals 601, 602, amplifier circuits 610, 615, distribution circuits 620, 625, and tuner ICs 630, 640, 650, 660.

  The input terminal 601 receives an RF signal, which is a broadcast wave signal of satellite broadcast, received by an antenna (not shown). The input terminal 602 receives an RF signal, which is a broadcast wave signal of terrestrial broadcasting, received by an antenna (not shown).

  The RF signal amplified by the amplifier circuit 610 is input to the input node of the distribution circuit 620. Distribution circuit 620 distributes and outputs the signal input to the input node to the first and second output nodes. The signal at the first output node of the distribution circuit 620 is input to the first satellite tuner IC 630. The signal at the second output node of the distribution circuit 620 is input to the second satellite tuner IC 640. Thus, the satellite broadcast RF signal input to the input terminal 601 can be input to each of the plurality of satellite broadcast tuner ICs.

  The RF signal amplified by the amplifier circuit 615 is input to the input node of the distribution circuit 625. Distribution circuit 625 distributes the signal input to the input node to the first and second output nodes and outputs the result. The signal at the first output node of distribution circuit 625 is input to first terrestrial tuner IC 650. The signal at the second output node of distribution circuit 625 is input to second terrestrial tuner IC 660. Thereby, the RF signal of the terrestrial broadcasting input to the input terminal 602 can be input to each of the plurality of tuner ICs for terrestrial broadcasting.

  As described above, when the TV general-purpose module is connected to a recorder or a set-top box, the TV is generally connected to the downstream side. For this reason, it is preferable that the TV general-purpose module is designed to be inexpensive and small without providing a loop-through terminal.

  In FIG. 3, the external view from the upper surface side of a general recorder module and a TV general-purpose module is compared at the same scale.

  Referring to FIG. 3, it is understood that the recorder module 500 (FIG. 1) provided with the loop-through terminal is considerably increased in size as compared with the TV general-purpose module 600 (FIG. 2).

  Also, if a recorder / set-top box, which is a relatively low-volume production type, is provided with a loop-through output, a mounting design for each model is required, so the design for mounting the loop-through function cannot be shared. Development efficiency may be reduced.

  Therefore, in the present embodiment, by combining with the TV general-purpose module 600 shown in FIG. 2, the function equivalent to that of the recorder module 500 having the loop-through is efficiently realized. The configuration of the distributor will be described.

  Referring to FIG. 8, tuner system 1000 according to the second embodiment includes distributors 100a and 100b and TV general-purpose module 600 shown in FIG. Distributors 100a and 100b are configured similarly to distributor 100 (FIG. 4) according to the first embodiment or distributor 100 # (FIG. 7) according to the modification of the first embodiment. That is, distributors 100a and 100b have loop through terminals 102a and 102b.

  Input terminal 101a of distributor 100a receives an RF signal (broadcast wave signal) of satellite broadcast received by an antenna (not shown). Similarly, the input terminal 101b of the distributor 100b receives an RF signal (broadcast wave signal) of terrestrial broadcasting received by an antenna (not shown).

  The amplifier circuits 110a and 110b amplify the RF signal input to the input terminals 101a and 101b, similarly to the amplifier circuit 110 of FIG. In the distributor 100a, the distribution circuit 120a distributes the output signal of the amplifier circuit 110a into two systems, and outputs them from each of the connection terminal 105a and the loop-through terminal 102a. Similarly, in the distributor 100b, the distribution circuit 120b distributes the output signal of the amplifier circuit 110b into two systems, and outputs them from each of the connection terminal 105b and the loop-through terminal 102b.

  The connection terminal 105a is connected to the input terminal 601 of the TV general-purpose module 600. That is, an RF signal that is a broadcast wave signal of satellite broadcasting is input to the input terminal 601. Similarly, the connection terminal 105b is connected to the input terminal 602 of the TV general-purpose module 600. That is, an RF signal that is a broadcast wave signal of terrestrial broadcast is input to the input terminal 601.

  In the TV general-purpose module 600, the RF signal (satellite broadcast) input to the input terminal 601 is amplified by the amplifier circuit 610 and then distributed by the distribution circuit 620, and the first satellite tuner IC 630 and the second satellite tuner.

It can have a function equivalent to 500. As a result, a tuner system equivalent to the recorder module 500 can be efficiently configured by combining components without performing a dedicated design.

  As described with reference to FIG. 6, it is preferable that the power supplies of the distributors 100a and 100b are supplied from the TV general-purpose module 600 through the connection terminals 105a and 105b. In this case, the power supply circuits 180a and 180b are configured to convert the power transmitted to the connection terminals 105a and 105b into an operating power supply inside the distributors 100a and 100b.

  In distributors 100a and 100b, ground terminals 107 and 108 similar to distributor 100 # (FIG. 7) may be provided so as to be connected to the ground terminal of the mounting board of TV general-purpose module 600.

  Next, the sizes of the tuner system 1000 according to the second embodiment and the recorder module 500 shown in FIG. 1 are compared in size using FIGS. As for tuner system 1000, an external view of a state in which distributors 100a and 100b and TV general-purpose module 600 are connected is shown.

  9 and 10 are front views of recorder module 500 shown in FIG. 1 and tuner system 1000 according to the second embodiment. 11 and 12 are side views of the recorder module 500 and the tuner system 1000, respectively. 13 and 14 are plan views of the recorder module 500 and the tuner system 1000 as viewed from above.

  Referring to FIG. 9, recorder module 500 is mounted on substrate 800. On the side surface of the recorder module 500, input terminals 501 and 503 and loop-through terminals 502 and 504 are provided so as to protrude in the horizontal direction with respect to the mounting surface of the substrate 800.

  Referring to FIG. 10, tuner system 1000 is mounted on substrate 800. Specifically, the TV general-purpose module 600 is mounted on the substrate 800, and the input terminals 601 and 602 corresponding to broadcast wave input terminals are provided along the vertical direction with respect to the mounting surface of the substrate 800. Furthermore, the connection terminals 105 a and 105 b of the distributors 100 a and 100 b are connected to the input terminals 601 and 602 of the TV general-purpose module 600.

  As a result, in the tuner system 1000, an empty space is generated in the vertical direction between the substrate 800 and the distributors 100a and 100b. Using this space, other components 190 and 195 of the tuner system can be arranged. 4 and 2, it is understood that the distributors 100a and 100b can be made smaller than the TV general-purpose module 600 because they have fewer components than the TV general-purpose module 600.

  Similar to the input terminals 501 and 503 and the loop-through terminals 502 and 504 of the recorder module 500, the input terminals 101a and 101b and the loop-through terminals 102a and 102b are connected to the input terminals 601 and 602 on the side surfaces of the distributors 100a and 100b.

In the present embodiment, the input terminals 101a and 101b and the loop-through terminals 102a and 102b are provided along the horizontal direction (direction parallel to the module mounting surface).

  Referring to FIG. 11, as shown in FIG. 3, recorder module 500 has a large occupied space in the depth direction (the left-right direction in FIG. 11). On the other hand, as shown in FIG. 12, the TV general-purpose module 600 is smaller than the recorder module 500 as shown in FIG. Therefore, the tuner system 1000 is reduced in size in the depth direction as compared with the recorder module 500. Further, since the TV general-purpose module 600 is a top-down module, the thickness of the module, that is, the size in the vertical direction is not so large.

  Referring to FIG. 13, the recorder module 500 is large in the width direction (up and down direction on the paper surface in FIG. 13) in addition to the depth direction (left and right direction on the paper surface in FIG. 13).

  On the other hand, as shown in FIG. 14, in the tuner system 1000, the TV general-purpose module 600 and the distributors 100a and 100b are arranged so as to overlap each other in the vertical direction (perpendicular to the paper surface of FIG. 14). In particular, the size in the depth direction (left and right direction in FIG. 14) can be reduced.

  That is, in FIG. 14, the tuner system 1000 occupies a smaller space than the recorder module 500 by an area 850 surrounded by a dotted line on the substrate 800. Further, it is possible to arrange other components of the tuner system using this area 850.

  In the tuner system 1000, there is a concern that the size in the vertical direction increases, but by making the TV general-purpose module 600 a top-down type, an increase in size can be suppressed. Moreover, as shown in FIG. 10, the space which can arrange | position another apparatus can be produced by the size increase to an up-down direction.

  13 and 14, the input terminals 101a and 101b and the loop-through terminals 102a and 102b in the tuner system 1000 according to the second embodiment are the same as the input terminals 501 and 503 of the recorder module 500 and the loop-through terminal 502. , 504 is understood to be provided in a similar manner.

  As described above, according to the second embodiment, a tuner system having a terminal arrangement and functions equivalent to those of a general recorder module 500 is obtained by combining the distributor according to the first embodiment or the modification and the TV general-purpose module. 1000 can be efficiently configured in a small size.

  Furthermore, since it is not necessary to manufacture the recorder module 500 alone, there is a possibility that the tuner module can be integrated into the TV general-purpose module 600. Thereby, further cost improvement can be expected by generalization of the design.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
