BEST MODE FOR CARRYING OUT THE INVENTION

以下、図面を参照して、この発明をディジタル衛星放送システムに適用した場合の実施 の形態について説明する。  Hereinafter, embodiments of the present invention applied to a digital satellite broadcasting system will be described with reference to the drawings.

第 1図は、本発明の実施例の概略構成をしめすブロック図である。図において、選択回 路 1には、デジタル衛星放送用デコーダからの映像信号 (以下 CS映像信号)と、衛星放 送チューナからの映像信号 (BS映像信号)と、 2つのテレビチューナからの映像信号 (TV 1、 TV2)が入力され、その中から 2つを選択して出力される。切換回路 2は、選択回路 1 の 2つの出力を受けて、これらを切換えて出力する。言い換えれば、 CPU3からの指示に 従レヽ、選択回路 1からの 2つの出力を交換して、後段の回路に供給する。  FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the present invention. In the figure, selection circuit 1 has a video signal from a digital satellite broadcast decoder (hereafter CS video signal), a video signal from a satellite broadcast tuner (BS video signal), and a video signal from two TV tuners. (TV 1, TV2) is input and two of them are selected and output. The switching circuit 2 receives the two outputs of the selection circuit 1 and switches and outputs them. In other words, according to the instruction from the CPU 3, the two outputs from the selection circuit 1 are exchanged and supplied to the subsequent circuit.

CPU3は、選択回路 1や切換回路 2他の動作を制御するものであり、制御の詳細につ いては、後でフローチャートを参照して説明する。これらのフローチャートに示された動作 は、 CPUに内蔵され^ ROM (リードオンリーメモリ）に記憶されたプログラムにより実現さ れる。また、 CPU3には、 RAM (ランダムアクセスメモリ)も内蔵されており、画面の現在の 表示状態や、直前の表示状態などを示す状態変数などを記憶できる。  The CPU 3 controls the operation of the selection circuit 1, the switching circuit 2, and the like, and details of the control will be described later with reference to a flowchart. The operations shown in these flowcharts are realized by a program built in the CPU and stored in a ROM (read only memory). The CPU 3 also has a built-in RAM (random access memory), and can store state variables indicating the current display state of the screen, the immediately preceding display state, and the like.

切換回路 2の一方の出力は、第 1選択スィッチ 4の端子 4aに供給される。また、第 1選択 スィッチ 4の端子 4bには、デジタル衛星放送の電子番組ガイド作成回路 (EPG) 8からの 象信号力 S供給されている。つまり、第 1選択スィッチ 4により通常の 象信号か、番組ガ イド画面かの選択力行われる。  One output of the switching circuit 2 is supplied to a terminal 4a of the first selection switch 4. The terminal 4b of the first selection switch 4 is supplied with an elephant signal S from an electronic program guide creation circuit (EPG) 8 for digital satellite broadcasting. In other words, the first selection switch 4 performs the selection of a normal elephant signal or a program guide screen.

第 1選択スィッチ 4により選択された映像信号は、水平方向の第 1圧縮回路 5に供給さ れる。第 2の圧縮回路 6には切換回路 2からの他方の出力が供給されている。これらの水 平方向の圧縮回路は、入力された映像信号を水平方向に 1 2に圧縮して出力する。そ こで、 2つの圧縮回路からの出力をタイミングを合わせて合成することにより、後で説明す るような 2画面の表示を実現することができる。尚、 2つの圧縮回路力 の信号読出しのタ イミングは、 CPU3によって制御される。第 2選択スィッチ 7も、 CPU3により制御され、第 2 選択スィッチ 7からの出力は、 2つの映像信号が合成されて 2画面表示が行われる映像 信号が得られる。 The video signal selected by the first selection switch 4 is supplied to a first compression circuit 5 in the horizontal direction. The other output from the switching circuit 2 is supplied to the second compression circuit 6. These horizontal compression circuits compress the input video signal to 12 in the horizontal direction and output it. Thus, by combining the outputs from the two compression circuits at the same timing, it is possible to realize a two-screen display as described later. In addition, the signal readout signal of the two compression circuit powers The timing is controlled by the CPU 3. The second selection switch 7 is also controlled by the CPU 3, and an output from the second selection switch 7 is a video signal in which two video signals are combined and a two-screen display is performed.

第 2選択スィッチ 7の出力は、第 3選択スィッチ 9の端子 9aに供給される。また、切換回 路 2の一方の出力は、第 3選択スィッチ 9の端子 9bに供給される。つまり、第 3選択スイツ チ 9は、 2画面表示か、通常の画面表示力を選択するために用いられる。切換回路 2の出 力が選択されている場合には、通常の画面表示となり、第 2選択スィッチ 7の出力が選択 されて!/ヽる場合には 2画面表示となる。  The output of the second selection switch 7 is supplied to the terminal 9a of the third selection switch 9. One output of the switching circuit 2 is supplied to a terminal 9b of the third selection switch 9. That is, the third selection switch 9 is used to select the two-screen display or the normal screen display power. When the output of the switching circuit 2 is selected, the normal screen display is performed. When the output of the second selection switch 7 is selected!

番組ガイド作成回路 8は、図示省略した CSデコーダ力ゝらの付加情報に基づき、番組ガ イドの画面を作成する。番組ガイドを作成するための付加情報は、 象内容のデータとと もに伝送されてレヽるものであり、常時、例えば 24時間程度分の番組ガイドを作成すること ができる情報力 S伝送されてレヽる。  The program guide creation circuit 8 creates a screen of a program guide based on the additional information of the CS decoder power not shown. The additional information for creating the program guide is transmitted together with the data of the target content, and is constantly transmitted, for example, the information power S capable of creating a program guide for, for example, about 24 hours. Reply

番組ガイド作成回路 8の出力は、第 4選択スィッチ 10の端子 10bにも供給されている。も う一方の端子 10aには第 3選択スィッチ 9の出力力 S供給されている。そして、第 4選択スィ ツチの出力が、テレビジョン受像機のディスプレイに表示される。ディスプレイは図面には 示していないが、 16対 9の横長ディスプレイである。  The output of the program guide creation circuit 8 is also supplied to the terminal 10b of the fourth selection switch 10. The other terminal 10a is supplied with the output power S of the third selection switch 9. Then, the output of the fourth selection switch is displayed on the display of the television receiver. The display is not shown in the drawing, but is a 16 to 9 landscape display.

この第 4選択スィッチは、通常の画面表示のときに、番組ガイド画面を映像信号にォー バ一ラップ表示するために用いられる。そして、第 4選択スィッチの選択の制御は、番組 ガイド作成回路 8からの出力の有無により基本的に制御される。つまり、番組ガイド作成 回路 8からの出力がある場合には、第 4選択スィッチ 10は端子 10bを選択して番組ガイド が画面上に表示される。  The fourth selection switch is used for displaying the program guide screen in an overlapped manner on the video signal during normal screen display. The control of the selection of the fourth selection switch is basically controlled by the presence or absence of the output from the program guide creation circuit 8. That is, when there is an output from the program guide creation circuit 8, the fourth selection switch 10 selects the terminal 10b and the program guide is displayed on the screen.

次に、第 2図から第 8図に従い、番組ガイドの表示態様について説明する。本発明のテ レビジョン受像機には第 7図に示すリモコン 11が付属していて、使用者がテレビジョン受 像機の動作を制御できる。このリモコン 11には、カーソル釦 12、 13、 14、 15や、番組ガイ ド表示釦 16、 2画面釦 17及び操作画面切換釦 18が設けられている。そして、これらの釦 が押されることにより、赤外線などを利用して、テレビジョン受像機本体の動作カ淛御され る。 Next, the display mode of the program guide will be described with reference to FIGS. The television receiver of the present invention is provided with a remote controller 11 shown in FIG. The operation of the image machine can be controlled. The remote controller 11 is provided with cursor buttons 12, 13, 14, and 15, a program guide display button 16, a two-screen button 17, and an operation screen switching button 18. When these buttons are pressed, the operation of the television receiver body is controlled using infrared rays or the like.

番組ガイド表示釦 16は番組ガイドを表示と非表示を切換えるために操作する釦である。 2画面釦 17は、 2画面表示と通常の画面表示の切換に用いられる。操作画面切換釦 18 は、 2画面表示のときのアクティブ画面を切換える釦である。また、カーソル釦 12〜15は、 番組ガイド力表示されているときに力一ソルを移動させるための釦である。  The program guide display button 16 is a button operated to switch the display and non-display of the program guide. The two-screen button 17 is used for switching between two-screen display and normal screen display. The operation screen switching button 18 is a button for switching the active screen when displaying two screens. The cursor buttons 12 to 15 are buttons for moving the cursor when the program guide force is displayed.

第 2図では、番組ガイド画面の表示の 2つの態様と 2画面表示への変化を示してレ、る。 つまり、 CS放送が通常表示されている状態 20で、番組ガイド表示釦 16が操作されると、 予め設定された番組ガイドの設定条件に応じて、分割表示 21 (番組ガイドのみの画面 21 Aと CSの映像画面 21Bが合成して表示されてレ、る）とオーバーラップ表示 22 (CSの映像 画面 22A上に重ねて番組ガイド画面 22B力表示されてレ、る)のレ、ずれかが選択されて表 示される。また、番組ガイドが表示されているこの状態で、 2画面釦 17を操作すると、番組 ガイドの表示態様が 21と 22の！/、ずれの場合であっても、 CSの映像画面 23Aに番組ガイ ド 23B力 Sオーバーラップ表示された画面と、別の映像信号源 (例えば BS放送画面）との 合成された 2画面表示 23が行われる。これは、使用者による 2画面表示の指示が、別の 映像信号源の映像を同時に見たレヽとレヽぅ意思表示であり、番組ガイドをオーバーラップ 表示した方が合理的と考えられるからである。また、画面 23の状態で、もう一度 2画面表 示釦 17を操作すると、設定条件に応じて画面 21又は画面 22の状態に戻る。  FIG. 2 shows two modes of the display of the program guide screen and a change to the two-screen display. In other words, when the program guide display button 16 is operated in the state 20 in which the CS broadcast is normally displayed, the divided display 21 (the screen 21A including only the program guide and the CS video screen 21B is synthesized and displayed, and overlap is displayed. 22 (Program guide screen 22B is superimposed and displayed on CS video screen 22A). It is displayed. Also, when the two-screen button 17 is operated in this state in which the program guide is displayed, the display mode of the program guide is changed to 21 and 22! / Even in the case of misalignment, the program guide 23B on the CS video screen 23A Power S Overlap display screen and another video signal source (for example, BS broadcast screen) combined 2 screen display 23 Is performed. This is because the user's instruction to display the two screens is a view of the simultaneous viewing of images from different video signal sources and an indication of the intention to view, and it is considered more reasonable to display the program guide in an overlapped manner. . When the two-screen display button 17 is operated again in the state of the screen 23, the screen returns to the state of the screen 21 or the screen 22 according to the setting conditions.

番組ガイドの設定条件は、使用者が指定することができ、例えば、第 8図に示した設定 画面 80を呼び出すことにより、番組ガイドの 2画面表示 (第 2図の 21)か 1画面表示 (第 2 図の 22)を設定できる。この設定画面 81において、リモコンのカーソル釦を操作すること によりチェックボックス 81、 82、釦 83、 84の間をカーソルが移動できる。そして、希望の画 面表示に対応するチェックボックス上にカーソルを移動させて、リモコンのセレクト釦 19を 押すと、チェックマークが表示される（第 8図の場合は 2画面表示に対応するチェックボッ クス 81にチェックマーク力 S付されてレヽる)。希望する条件を設定して、 OK釦 83に力一ソル を移動せしめ、セレクト釦 19を操作すると、その時の設定画面の条件が記憶される。キヤ ンセル釦 84でセレクト釦 19を操作すると、設定は変更されずに、設定画面 80が終わる。 第 3図及び第 4図は、 2画面表示が行われてレ、るときの番組ガイド表示への状態変化を 示している。第 3図の様に CS映像 31 Aが左側に位置しており、他の映像信号源の映像 3 1B力右側に位置しているとき、そして、左側の CS映像力 Sアクティブであるときに、番組ガ イド表示釦 16が操作されると、 32に示す画面が表示される。画面 32では、 CS画面 32A 上に番組ガイド画面 32B力オーバーラップ表示され、他の映像信号源の画面 32Cはそ のまま表示される。 The setting conditions of the program guide can be specified by the user.For example, by calling the setting screen 80 shown in FIG. 8, the program guide can be displayed in two screens (21 in FIG. 2) or one screen display ( You can set 22) in Fig. 2. In this setting screen 81, operating the cursor button of the remote control Allows the cursor to move between the check boxes 81 and 82 and the buttons 83 and 84. Then, move the cursor to the check box corresponding to the desired screen display and press the select button 19 on the remote control to display a check mark (in the case of FIG. 8, the check box corresponding to the two-screen display is displayed). Check box power S is attached to box 81). After setting the desired conditions, moving the cursor to the OK button 83 and operating the select button 19, the conditions on the setting screen at that time are stored. When the select button 19 is operated with the cancel button 84, the setting screen 80 is ended without changing the setting. FIG. 3 and FIG. 4 show the state change to the program guide display when the two-screen display is performed. As shown in FIG. 3, when the CS image 31A is located on the left side and the image 31B of another image signal source is located on the right side, and when the CS image force S on the left side is active, When the program guide display button 16 is operated, a screen shown at 32 is displayed. On the screen 32, the program guide screen 32B is overlapped on the CS screen 32A, and the screen 32C of another video signal source is displayed as it is.

第 4図の様に、 CS映像 41Aが右側に位置しており、他の映像信号源の映像 41Bが左 側に位置しているとき、そして、右側の CS映像力 Sアクティブであるときに、番組ガイド表示 釦 16が操作されると、 42に示す画面が表示される。画面 42では、 CS画面 42B上に番組 ガイド画面 42C力オーバーラップ表示され、他の映像信号源の画面 42Aはそのまま表示 される。このように、 2画面表示の場合には、番組ガイドは、必ずオーバーラップ表示とさ れる。  As shown in FIG. 4, when the CS image 41A is located on the right side and the image 41B of another image signal source is located on the left side, and when the CS image power S on the right side is active, When the program guide display button 16 is operated, a screen shown at 42 is displayed. On the screen 42, the program guide screen 42C is overlapped on the CS screen 42B, and the screen 42A of another video signal source is displayed as it is. Thus, in the case of the two-screen display, the program guide is always displayed in an overlapped manner.

第 5図は、 2画面表示釦 17が操作されたときの処理を示すフローチャートである。ただし、 第 5図では、省略されているが、 2画面表示釦力操作されるとまず、現在の表示状態を示 す変数をチェックし、 2画面表示が行われている場合には、その前の表示状態に戻る処 理を行う。  FIG. 5 is a flowchart showing a process when the two-screen display button 17 is operated. However, although omitted in FIG. 5, when the two-screen display button is operated, first, a variable indicating the current display state is checked. Perform processing to return to the display state of.

このフローチャートと第 1図に基づき、各表示状態について説明する。初期状態として 通常画面力 S表示されていると仮定する。通常の表示状態では、第 3選択スィッチ 9は、端 子 9bを選択し、第 4選択スィッチが端子 10aを選択してレヽるので、選択回路 1及び切換回 路 2により選ばれた一つの映像信号源からの映像信号、例えば CS映像信号が画面に表 示されている。そこで、 2画面表示釦 17が操作されると (ステップ 51)、番組ガイドが表示 されているかどうかがチェックされる (ステップ 52)。このチェックは例えば、 CPUに EPGの 表示状態を示す状態変数が記憶されており、これをチェックすることにより行われる。 この時、通常表示が初期状態と仮定しているので、ステップ 52に進み、別の映像信号 源 (例えば BS放送映像）と始めに表示されてレ、た映像 (例えば地上波放送映像)力 ¾画 面表示されて、元に戻る (ステップ 54)。この時、第 3選択スィッチ 9は端子 9aを選択し、第 4選択スィッチ 10は端子 10aを選択する。第 1選択スィッチ 4は端子 4aを選択しており、 2 つの水平圧縮回路 5、 6には、選択回路 1により選択された 2つの映像信号が供給されて、 夫々水平方向に 2分の 1に圧縮されて出力される。そして、 CPU3により 2つの圧縮回路 力 の読出し及び第 2選択スィッチ 7の切換力制御されることにより、 2つの映像信号が合 成された画像が、第 3選択スィッチ 9の端子 9aに供給される。 Each display state will be described based on this flowchart and FIG. As the initial state It is assumed that the normal screen power S is displayed. In a normal display state, the third selection switch 9 selects the terminal 9b, and the fourth selection switch selects the terminal 10a for display, so that one video selected by the selection circuit 1 and the switching circuit 2 is selected. A video signal from a signal source, for example, a CS video signal is displayed on the screen. Then, when the two-screen display button 17 is operated (step 51), it is checked whether or not the program guide is displayed (step 52). This check is performed by, for example, storing a state variable indicating the display state of the EPG in the CPU, and checking this. At this time, since the normal display is assumed to be in the initial state, the process proceeds to step 52, where another video signal source (for example, a BS broadcast video) and the first video (for example, a terrestrial broadcast video) are displayed. The screen is displayed and returns (step 54). At this time, the third selection switch 9 selects the terminal 9a, and the fourth selection switch 10 selects the terminal 10a. The first selection switch 4 selects the terminal 4a, and the two video signals selected by the selection circuit 1 are supplied to the two horizontal compression circuits 5 and 6, and each of them is reduced by half in the horizontal direction. The output is compressed. Then, the CPU 3 controls the readout of the power of the two compression circuits and the control of the switching power of the second selection switch 7, whereby an image in which the two video signals are synthesized is supplied to the terminal 9 a of the third selection switch 9. .

2画面表示釦 17が操作されたときに、番組ガイドが表示されてレヽる、すなわち、第 2図の 21または 22の画面が表示されてレ、たとすると、ステップ 52の判断の後、ステップ 55が実 行される。従って、第 2図の 23の画面、つまり、 CS画面と番組ガイドのオーバーラップ表 示と別の映像信号の分割表示が行われて、元に戻る (ステップ 56)。  When the two-screen display button 17 is operated, the program guide is displayed and displayed. That is, if the screen of FIG. Is executed. Accordingly, the screen 23 shown in FIG. 2, that is, the overlap display of the CS screen and the program guide and the divisional display of another video signal are performed, and the process returns to the original (step 56).

ここで、第 2図の画面 21が表示されている場合は、第 1選択スィッチ 4は、端子 4bを選 択しており、第 3選択スィッチ 9は端子 9a、第 4選択スィッチ 10は端子 10aを選択している。 第 2図の 23の画面が表示されている場合には、第 3選択スィッチ 9は端子 9bを選択し、第 4選択スィッチ 10は番組ガイド作成回路 8の出力に基づき端子 10a、 10b間を切換えられ ている。そして、ステップ 55が実行されることにより、第 1選択スィッチ 4の端子 4aに供給さ れる映像信号が、選択回路 1及び切換回路 2の選択動作により、 CS映像信号となる。第 1選択スィッチ 4は、番組ガイド作成回路 8の出力に基づき、端子 4aと 4bの間を切換えら れるので、一方の水平圧縮回路 5には、 CS映像信号と番組ガイドとがオーバーラップさ れた信号が供給される。他方の圧縮回路 6には、選択回路 1と切換回路 2により選択され た映像信号が供給されており、圧縮回路 5、 6の出力の読出しと第 2選択スィッチ 7の選択 力制御されて合成された 2分割信号が第 3選択スィッチ 9及び第 4選択スィッチ 10を介し て表示される。 Here, if the screen 21 in FIG. 2 is displayed, the first selection switch 4 has selected the terminal 4b, the third selection switch 9 has the terminal 9a, and the fourth selection switch 10 has the terminal 10a. Is selected. When the screen 23 shown in FIG. 2 is displayed, the third selection switch 9 selects the terminal 9b, and the fourth selection switch 10 switches between the terminals 10a and 10b based on the output of the program guide creation circuit 8. It has been. Then, by executing step 55, the signal is supplied to the terminal 4a of the first selection switch 4. The video signal to be converted into a CS video signal by the selection operation of the selection circuit 1 and the switching circuit 2. The first selection switch 4 can switch between the terminals 4a and 4b based on the output of the program guide creation circuit 8, so that the CS video signal and the program guide overlap on one horizontal compression circuit 5. Signal is supplied. The video signal selected by the selection circuit 1 and the switching circuit 2 is supplied to the other compression circuit 6, and the output of the compression circuits 5 and 6 is read out and the selection power of the second selection switch 7 is controlled and synthesized. The two divided signals are displayed via the third selection switch 9 and the fourth selection switch 10.

第 6図は、番組ガイド表示釦 16が操作されたときの処理を示すフローチャートである。こ のフローチャートにおいても、省略されているが、表示状態を示す状態変数が調べられ、 現在番組ガイドが表示されているならば、次に進まず、元の画面に戻る。番組ガイドが表 示されていなければ、番組ガイド表示釦 17が押されたことを CPU3が検出すると、 CS映 像信号力 ¾1択されていてし力 ¾アクティブ状態かどうかが調べられる。これは、例えば、 C PU3に記憶されている状態変数によりチェックされる。 Noの場合は、何もせずに元に戻 る。これは、番組ガイドは、 CS放送に関連するものであり、それ以外の映像信号源の画 像が表示されてレヽる場合には、番組ガイドを表示する意味が無レヽからである。  FIG. 6 is a flowchart showing processing when the program guide display button 16 is operated. Although omitted in this flowchart, the state variables indicating the display state are checked, and if the program guide is currently displayed, the program returns to the previous screen without proceeding. If the program guide is not displayed, when the CPU 3 detects that the program guide display button 17 has been pressed, it is checked whether the CS video signal power has been selected and the power is in the active state. This is checked, for example, by a state variable stored in CPU3. If No, go back without doing anything. This is because the program guide is related to CS broadcasting, and it is meaningless to display the program guide when images of other video signal sources are displayed and viewed.

CS映像力 S表示されしかもアクティブ状態であれば、ステップ 64に進み、現在の状態が 2 画面表示かどうかを調べる。この調査も、 CPU3内部の状態変数により調べることができ る。 2画面表示の状態であれば、第 3図、第 4図に見られる様に、 CS映像信号と番組ガイ ド画面信号とをオーバーラップ表示する。第 1図での状態を説明すると、番組ガイド釦 16 が操作されたときには、第 1選択スィッチ 4は端子 4aを、第 3選択スィッチ 9は端子 9aを、 第 4選択スィッチ 10は端子 10aを選択してレ、る。そして、ステップ 65の実行により、必要に より、切換回路 2が選択回路 1の出力を切換えて、端子 4aに CS映像信号を供給し、第 1 選択スィッチ 4が、番組ガイド作成回路 8の出力の状態により切換制御され、圧縮回路 5 に CS映像信号と番組ガイドの重ね合わされた画像信号が供給される。そして、圧縮回路 5、 6からの読出しと第 2選択スィッチ 7の切換のタイミングが CPU3により必要に応じて変 更され、元の CS 信号が表示されてレ、た場所に、 CS映像信号と番組ガイド画面のォ ーバ一ラップ表示が行われる (第 3図、第 4図参照)。 If the CS image S is displayed and the display is in the active state, the process proceeds to step 64 to check whether the current state is the two-screen display. This check can also be checked using the state variables inside the CPU3. In the two-screen display state, the CS video signal and the program guide screen signal are overlapped as shown in Figs. 3 and 4. Explaining the state in FIG. 1, when the program guide button 16 is operated, the first selection switch 4 selects the terminal 4a, the third selection switch 9 selects the terminal 9a, and the fourth selection switch 10 selects the terminal 10a. I'll do it. By executing step 65, if necessary, the switching circuit 2 switches the output of the selection circuit 1, supplies the CS video signal to the terminal 4a, and the first selection switch 4 outputs the output of the program guide creation circuit 8 Switching is controlled by the state, and the compression circuit 5 Is supplied with a superimposed image signal of the CS video signal and the program guide. Then, the timing of reading from the compression circuits 5 and 6 and switching of the second selection switch 7 is changed by the CPU 3 as needed, and the original CS signal is displayed, and the CS video signal and the program Overlap display of the guide screen is performed (see Fig. 3 and Fig. 4).

ステップ 64で 2画面表示が行われていないと判断されると、ステップ 67に進み、使用者 により設定されてレヽる表示状態の設定を調べる。 1画面表示が指定されてレヽる場合には、 ステップ 69に進みオーバーラップ表示 (第 2図の画面 22)が行われる。 2画面表示が指定 されてレ、る場合には、ステップ 68に進み、 2画面表示 (第 2図の 21)が行われる。表示状 態の設定のチェックには、 CPU3に記憶されてレヽるメモリの状態を調べることにより行われ る。  If it is determined in step 64 that the two-screen display is not being performed, the flow advances to step 67 to check the display state setting set by the user. If the single-screen display is designated and the display goes to step 69, the overlap display (screen 22 in FIG. 2) is performed. If the two-screen display is designated, the process proceeds to step 68, where the two-screen display (21 in FIG. 2) is performed. The setting of the display state is checked by checking the state of the memory stored in the CPU 3.

ここで、ステップ 64で 2画面表示が行われていないと判断された場合は、選択回路 1及 び切換回路 2の選択により、第 3選択スィッチ 9の端子 9aに CS映像信号が供給され、そ のまま、第 4選択スィッチ 10を介して表示されてレ、る状態である。この状態から、オーバー ラップ表示を行うときには、第 4選択スィッチ 10により、番組ガイド作成回路 8出力の状態 で、端子 10aと 10bの間を切換えることにより、番組ガイド画面と CS映像信号とを合成す る。また、 2画面表示を行うときには、選択回路 1と切換回路 2による選択により水平方向 の圧縮回路 6には、 CS映像信号を供給し、端子 4bを選択した第 1選択スィッチ 4により、 番組ガイド画面の信号が圧縮回路 5に供給されて、 2つの圧縮回路 5、 6からの読出しと、 第 2選択スィッチ 7の選択により合成された信号が、第 3選択スィッチ 9及び第 4選択スイツ チ 10を介して出力される。  Here, if it is determined in step 64 that the two-screen display is not being performed, the selection circuit 1 and the switching circuit 2 are selected to supply the CS video signal to the terminal 9a of the third selection switch 9. It is displayed via the fourth selection switch 10 as it is. When performing the overlap display from this state, the fourth selection switch 10 switches between the terminals 10a and 10b in the state of the output of the program guide creation circuit 8 so that the program guide screen and the CS video signal are combined. You. When a two-screen display is performed, a CS video signal is supplied to the horizontal compression circuit 6 by selection by the selection circuit 1 and the switching circuit 2, and the program guide screen is selected by the first selection switch 4 that has selected the terminal 4b. Is supplied to the compression circuit 5, and a signal synthesized by reading from the two compression circuits 5 and 6 and selecting the second selection switch 7 is output to the third selection switch 9 and the fourth selection switch 10. Output via

以上述べたように、本発明によれば、番組ガイドを表示した場合でも、放送映像の表示 を妨げることがなぐ又、番組ガイドの表示の態様を使用者力設定でき、有効である。 産業上の利用可能性 As described above, according to the present invention, even when the program guide is displayed, the display of the broadcast video is not obstructed, and the display mode of the program guide can be set by the user, which is effective.
