モリ部(7)に映像信号が記憶される。46 input in the memory control unit (6)
The number is stored in the memory section (7). When one screen of one channel has been stored, the next channel is selected by the channel selection switching section (3), and the video signal is stored in the memory section (7) in the same process as described above.
これらの動作が指定された画面数だけ繰返され、映像信
号がメモリ部(7)に順次記憶される。These operations are repeated for the designated number of screens, and the video signals are sequentially stored in the memory section (7).

示部(lO)により、たとえば第4図のようにP1〜P
4からなる多画面が表示される。Next, the memory control unit (θ) converts the time and reads the memory contents, and the signal processing unit (9) and image display unit (lO) process the P1 to P1 as shown in FIG.
A multi-screen consisting of 4 is displayed.
なお、この例では、画面数は4つであり、また各画像は
切換時間に応じた静止画となっている。In this example, the number of screens is four, and each image is a still image corresponding to the switching time.
しかしながら、上記従来の多画面表示テレビジョン受信
機においては、各表示画面P1〜P4がどのチャンネル

などがわかりにくいという欠点があった。However, the above-mentioned conventional multi-screen display television receiver has the disadvantage that it is difficult to tell which channel's broadcast is being received on each of the display screens P1 to P4, and whether it is an audio multiplex broadcast.
[発明の概要]
この発明は上記従来の欠点を解消するためになりれたも
ので、放送チャンネルや音声多重放送などの情報を各表
示画面ごとに表示するようにして、視聴者の便宜をはか
った多画面表示テレビジョン受信機を提供することを目
的としている。[Summary of the Invention] This invention was developed to solve the above-mentioned conventional drawbacks, and provides information such as broadcast channels and audio multiplex broadcasts on each display screen for the convenience of viewers. The purpose of this invention is to provide a multi-screen display television receiver.
[発明の実施例] 以下、この発明の実施例を図面にしたがって説明する。[Embodiments of the invention] Embodiments of the present invention will be described below with reference to the drawings.
第1図はこの発明による多画面表示テレビジョン受信機
の実施例を示すブロック回路図である。FIG. 1 is a block circuit diagram showing an embodiment of a multi-screen display television receiver according to the present invention.
図において、第3図と同一部分には同一符号を付して、
その説明は省略する。第1図では、第3図の構成に信号
検出回路(11)、文字発生回路(12)、文字混合回
路(13)、音声検波回路(14)が新たに付加されて
いる。In the figure, the same parts as in Figure 3 are given the same reference numerals.
The explanation will be omitted. In FIG. 1, a signal detection circuit (11), a character generation circuit (12), a character mixing circuit (13), and a voice detection circuit (14) are newly added to the configuration of FIG. 3.
次に動作について説明する。放送電波が受信されてから
(1)〜(10)の各部によって多画面表示がなされる
までのプロセスは第3図の従来の場合とまったく同じで
ある。Next, the operation will be explained. The process from the reception of broadcast waves to the multi-screen display by each section (1) to (10) is exactly the same as the conventional case shown in FIG.
信号検出回路(11)は、選局部(2)で選局されたチ
ャンネルを検出し、文字発生回路(12)にその放送チ
ャンネルに対応した番号を発生させる。たとえば、4チ
ヤンネルが選局されておれば、文字発生回路(12)か
らr4Jの文字が発生される0文字発生回路(12)か
ら発生された番号は文字混合回路(13)を介してメモ
リコントロール部(6)に入力される。The signal detection circuit (11) detects the channel selected by the channel selection section (2) and causes the character generation circuit (12) to generate a number corresponding to the broadcast channel. For example, if channel 4 is selected, the character r4J will be generated from the character generation circuit (12), and the number generated from the 0 character generation circuit (12) will be controlled in memory via the character mixing circuit (13). The information is input to section (6).
一方、音声検波回路(14)は音声放送が多重放送かど
うかを判定して、その判定内容を信号検出回路(11)
に送る。このとき、音声放送がたとえばステレオ放送で
あれば、文字発生回路(12)から「ステレオjの文字
を発生させ、文字混合回路(13)を介してメモリコン
トロール部(8)に入力する。On the other hand, the audio detection circuit (14) determines whether the audio broadcast is a multiplex broadcast, and transmits the determination content to the signal detection circuit (11).
send to At this time, if the audio broadcast is, for example, a stereo broadcast, the character "stereo j" is generated from the character generation circuit (12) and inputted to the memory control section (8) via the character mixing circuit (13).
以上の動作を選局切換部(3)により各画面ごとに行な
い、放送チャンネルの番号やステレオ放送であることな
どの表示を各画面に付加して、たとえば第2図のように
多画面表示する。The above operation is performed for each screen by the channel selection switching unit (3), and displays such as the broadcast channel number and the fact that it is a stereo broadcast are added to each screen to display a multi-screen display as shown in Fig. 2, for example. .
第2図において、表示画面P1には数字r4Jが表示さ
れており、これは画面P1が4チヤンネルの放送を受信
していることを示している。また、表示画面P2には数
字i’lOJと「ステレオjの文字が一緒に表示されて
おり、これは画面P2が10チヤンネルの放送を受信し
ていて、かつその音声放送がステレオ放送であることを
示している。これによって、視聴者は各表示画面の放送
チャンネルや、ステレオ放送であるかどうか等を視覚的
に容易に確認することができる。In FIG. 2, the number r4J is displayed on the display screen P1, which indicates that the screen P1 is receiving broadcasts of 4 channels. In addition, the numbers i'lOJ and the letters "stereo j" are displayed together on the display screen P2, which means that the screen P2 is receiving broadcasts from 10 channels and the audio broadcasts are stereo broadcasts. This allows the viewer to easily visually confirm the broadcast channel of each display screen, whether or not it is a stereo broadcast, etc.
なお、上記実施例においては、画面数を4つとした場合
を示したが、2画面以上ならばいくつであってもかまわ
ない。また、表示内容も、放送チャンネルや音声表示に
限らず、たとえば第2図の表示画面P4に示したように
、映像の種類(ここでは「ビデオj)を表わすものであ
ってもよい。In the above embodiment, the case where the number of screens is four is shown, but any number may be used as long as there are two or more screens. Further, the display content is not limited to broadcast channels and audio display, but may also indicate the type of video (here, "video j") as shown in display screen P4 in FIG. 2, for example.
さらに、上記実施例では、各画像が静止画となっている
が、この発明は動画方式の場合にも適用することが可能
である。Further, in the above embodiment, each image is a still image, but the present invention can also be applied to a moving image system.
[発明の効果]
以上のように、この発明による多画面表示テレビジョン
