Description

本発明は、テレビ放送視聴システム及びテレビ受信機とワイヤレス受信機並びにテレビ放送視聴方法に関し、特にテレビジョン受信機やＤＶＤプレーヤーのマルチチャンネル多言語音声信号を同時にワイヤレスで複数の視聴者に伝送し、視聴者が自分のニーズに合わせて選んだ音声コンテンツを再生させ利用できる音声システムに関する。   The present invention relates to a television broadcast viewing system, a television receiver, a wireless receiver, and a television broadcast viewing method, and in particular, multi-channel multilingual audio signals of a television receiver and a DVD player are simultaneously wirelessly transmitted to a plurality of viewers, The present invention relates to an audio system that can reproduce and use audio contents selected by viewers according to their needs.

アナログテレビジョン放送では音声信号の伝送に主チャンネル（主音声）と副チャンネル（副音声）の２つの伝送路を設けた方式が採られており、２ヶ国語放送とステレオ放送の選択受信ができる。また、テレビジョン受信機では、主音声、副音声、または主音声＋副音声を切り替えてスピーカから聞く方法や、ヘッドホン端子を通して聞く方法が一般に使用されている。   Analog television broadcasting employs a method in which two transmission channels, a main channel (main audio) and a sub-channel (sub audio), are provided for audio signal transmission, and can selectively receive bilingual and stereo broadcasting. . Further, in a television receiver, a method of listening from a speaker by switching main sound, sub sound, or main sound + sub sound, or a method of listening through a headphone terminal is generally used.

有線ヘッドホンを使用すると、テレビ受信機からの距離を遠くてできないことや、大型テレビの画面が見づらい問題点に対して、図３の方法が提案されている（特許文献１参照）。この方法によって、ヘッドホンからスピーカと同じ内容の音声を聞くことができる。図３（ａ）は音声無線信号送信器を含むテレビ受信機であり、図３（ｂ）はワイヤレス音声受信機である。   The method of FIG. 3 has been proposed for the problems that the use of wired headphones makes it impossible to increase the distance from the television receiver and the problem that it is difficult to see the screen of a large television (see Patent Document 1). By this method, it is possible to listen to the same sound as the speaker from the headphones. FIG. 3A shows a television receiver including an audio radio signal transmitter, and FIG. 3B shows a wireless audio receiver.

しかし、図３の方法は２画面テレビに対応できないため、図４の方法が提案されている（特許文献２参照）。ヘッドホン側で受信したい音声信号をテレビ本体側でリモコンなどを通して選択し、無線信号で送信する（図４（ａ））。ワイヤレス受信機（図４（ｂ））はその無線信号を受信して再生する。これによってヘッドホンからスピーカと同じ内容、または違う内容の音声を聞くことができる。
特開平３−２６５２９４号公報 特開平７−５９０２５号公報 However, since the method of FIG. 3 cannot be applied to a two-screen television, the method of FIG. 4 has been proposed (see Patent Document 2). An audio signal to be received on the headphone side is selected on the TV main body side through a remote controller or the like, and is transmitted as a radio signal (FIG. 4A). The wireless receiver (FIG. 4B) receives and reproduces the radio signal. As a result, it is possible to hear the same or different sound from the speaker through the headphones.
JP-A-3-265294 JP 7-59025 A

図４の方法では、送信された無線信号に１チャンネルの音声信号しか存在しない。このため、多視聴者や多チャンネル（多言語）に対応することができない。例えば、視聴者１はスピーカから親画面の主音声（日本語）を聴き、視聴者２はワイヤレスヘッドホンで親画面の副音声（英語）を聴いている状態では、視聴者３は子画面の音声を聴くことができない。   In the method of FIG. 4, there is only one channel audio signal in the transmitted radio signal. For this reason, it cannot respond to many viewers and many channels (multiple languages). For example, when the viewer 1 listens to the main audio (Japanese) on the main screen from the speaker and the viewer 2 listens to the sub-audio (English) on the main screen with wireless headphones, the viewer 3 can hear the audio on the child screen. I can't hear you.

また、マルチメディアＤＶＤでは、同じ画面に対して複数種類の言語（マルチ言語）音声が入っている。複数の視聴者は、同じ画面に対して同時にマルチ言語（例え、日本語、英語、中国語など）を聴くことはできない。   In addition, the multimedia DVD contains a plurality of types of language (multi-language) sound on the same screen. Multiple viewers cannot listen to multiple languages (eg, Japanese, English, Chinese, etc.) on the same screen at the same time.
