次に、テレビ受信方法について説明する。
まず、テレビ受信機10側で所望のチャンネルの映像/音声信号を視聴する場合は、図示しないリモコン等によって所望のチャンネルを選択すると(ステップS1)、チューナ13,14により地上波アンテナ41と衛星放送アンテナ42とからの信号を取り込むアンテナ端子11,12からのアンテナ信号から所望のチャンネルの信号が抽出され、さらに映像/音声信号に変換されて出力され、セレクタ15によって選択された映像/音声信号が映像/音声出力回路20に出力される(ステップS2)。
Next, a television receiving method will be described.
First, when viewing a video / audio signal of a desired channel on the television receiver 10 side, when the desired channel is selected by a remote controller (not shown) or the like (step S1), the tuners 13 and 14 use the terrestrial antenna 41 and satellite broadcasting. A signal of a desired channel is extracted from the antenna signals from the antenna terminals 11 and 12 that take in signals from the antenna 42, converted into a video / audio signal, and output. The video / audio signal selected by the selector 15 is output. It is output to the video / audio output circuit 20 (step S2).

一方、PC30側で所望のチャンネルの映像/音声信号を視聴する場合は、フレキシブル専用ケーブル40のコネクタを、テレビ受信機10側の端子21とPC30側の端子31に装着する(ステップS3)。ここで、フレキシブル専用ケーブル40は上述したように柔軟性を有するとともに、そのコネクタはワンタッチ装着できる形状及び構造となっているため、フレキシブル専用ケーブル40の接続を容易に行える。   On the other hand, when viewing a video / audio signal of a desired channel on the PC 30 side, the connector of the flexible dedicated cable 40 is attached to the terminal 21 on the television receiver 10 side and the terminal 31 on the PC 30 side (step S3). Here, the flexible dedicated cable 40 has flexibility as described above, and the connector has a shape and a structure that can be mounted with one touch, so that the flexible dedicated cable 40 can be easily connected.

フレキシブル専用ケーブル40の接続を完了した後、PC30側の電源を投入し、図示しないキーボードやリモコン等から地上波又は衛星放送の選択と(ステップS4)、所望のチャンネルの選択とを行う(ステップS5)。このとき、コントローラ34により、フレキシブル専用ケーブル40を介してテレビ受信機10側に地上波又は衛星放送の選択要求が出される(ステップS6)。   After the connection of the flexible dedicated cable 40 is completed, the PC 30 is turned on, and terrestrial or satellite broadcasting is selected from a keyboard or remote controller (not shown) (step S4) and a desired channel is selected (step S5). ). At this time, the controller 34 issues a selection request for terrestrial or satellite broadcasting to the television receiver 10 via the flexible dedicated cable 40 (step S6).

テレビ受信機10側では、コントローラ19がその選択要求に応じて切換スイッチ18を制御し(ステップS7)、アンテナ端子11,12からのアンテナ信号のいずれかをフレキシブル専用ケーブル40を介してPC30側に供給する(ステップS8)。   On the television receiver 10 side, the controller 19 controls the changeover switch 18 in response to the selection request (step S7), and any one of the antenna signals from the antenna terminals 11 and 12 is sent to the PC 30 side via the flexible dedicated cable 40. Supply (step S8).

PC30側では、チューナ32により、端子31から供給されるアンテナ信号から所望のチャンネルの信号が抽出され(ステップS9)、さらに映像/音声信号に変換して図示しない映像/音声出力回路に出力される(ステップS10)。また、録画要求がある場合は、チューナ32によって抽出された所望のチャンネルの信号が録画部35により録画される。   On the PC 30 side, the tuner 32 extracts a signal of a desired channel from the antenna signal supplied from the terminal 31 (step S9), further converts it into a video / audio signal and outputs it to a video / audio output circuit (not shown). (Step S10). When there is a recording request, a signal of a desired channel extracted by the tuner 32 is recorded by the recording unit 35.

このように、本実施形態では、映像/音声信号や少なくともアンテナ信号の出力要求を示す要求信号の伝送が可能な統合型のフレキシブル専用ケーブル40をテレビ受信機10の端子21とPC30の端子31とに接続し、PC30のコントローラ34からテレビ受信機10のコントローラ19に要求信号が出されると、そのコントローラ19により、切換スイッチ18による切り換えが制御され、受信したアンテナ信号がPC30側に出力するように切り換えられるようにしたので、従来の太く柔軟性に欠ける特性を持つアンテナ線を用いることなく、フレキシブル専用ケーブル40でアンテナ信号の受信が可能となることから、そのフレキシブル専用ケーブル40の柔軟性等によってフレキシブル専用ケーブル40の取り付けや取り外しを極めて容易に行うことができる。   As described above, in this embodiment, the integrated flexible dedicated cable 40 capable of transmitting the request signal indicating the output request of the video / audio signal and at least the antenna signal is connected to the terminal 21 of the television receiver 10 and the terminal 31 of the PC 30. When a request signal is output from the controller 34 of the PC 30 to the controller 19 of the television receiver 10, the controller 19 controls switching by the changeover switch 18 so that the received antenna signal is output to the PC 30 side. Since the antenna signal can be received by the flexible dedicated cable 40 without using the conventional thick and inflexible antenna wire, the flexibility of the flexible dedicated cable 40 can be used. Attaching and removing the flexible cable 40 It can be carried out very easily.

また、本実施形態では、フレキシブル専用ケーブル40を介して供給されるテレビ受信機10側からのアンテナ信号の所望のチャンネルの信号がチューナ32によって抽出されるとともに、PC30側で録画要求がある場合は録画部35に録画することができるとともに、PC30側からの映像/音声信号をフレキシブル専用ケーブル40を介してテレビ受信機10側に供給することで、テレビ受信機10側での視聴を行うことができる。   Further, in the present embodiment, a signal of a desired channel of an antenna signal supplied from the television receiver 10 side supplied via the flexible dedicated cable 40 is extracted by the tuner 32, and when there is a recording request on the PC 30 side. In addition to being able to record in the recording unit 35, video / audio signals from the PC 30 side are supplied to the television receiver 10 side via the flexible dedicated cable 40, so that viewing on the television receiver 10 side can be performed. it can.

また、本実施形態では、PC30側のコントローラ34からテレビ受信機10側のコントローラ19にフレキシブル専用ケーブル40を介して地上波又は衛星放送の選択要求を示す信号が出されると、テレビ受信機10側のコントローラ19により切換スイッチ18による切り換えが制御され、地上波又は衛星放送のいずれかアンテナ信号がPC30側に供給されるようにした。   In the present embodiment, when a signal indicating a selection request for terrestrial or satellite broadcasting is output from the controller 34 on the PC 30 side to the controller 19 on the TV receiver 10 side via the flexible dedicated cable 40, the TV receiver 10 side The controller 19 controls the switching by the selector switch 18 so that either the terrestrial or satellite broadcast antenna signal is supplied to the PC 30 side.

これにより、従来では、地上波と衛星放送との両方を受信する際、両方のアンテナ線を、つまり2本接続しなければならなかったが、本実施形態では、1本のフレキシブル専用ケーブル40を接続し、テレビ受信機10側で地上波又は衛星放送の供給が切り換えられることから、接続の煩わしさを無くすことができる。   Thus, conventionally, when receiving both terrestrial and satellite broadcasts, both antenna lines, that is, two cables must be connected. In the present embodiment, one flexible dedicated cable 40 is used.
