Abstract

PURPOSE:To avoid the display of a signal not suitable for viewing by providing a function discriminating and executing whether or not a signal inputted at present is to be displayed as a TV signal through the input of a control signal. CONSTITUTION:A TV signal reproducer 11 outputs a control signal 14 representing the reproduction and output to a television receiver 12 while the recorded TV signal is reproduced and outputted and the receiver 12 uses a control signal from the reproducing device 11 to display the input signal as the TV signal. On the other hand, when the reproducer 11 cannot reproduce and output the TV signal to be recorded to the receiver 12, the receiver 12 discriminates the signal 14 representing it by a discrimination means 121. The discrimination output controls the switching means 122 to stop the display of the signal from the reproducer 11 as the TV signal. Then the signal is switched into a TV signal such as an external input signal inputted via a terminal 123 from other TV signal reproducer prepared in advance and the selected signal is displayed for the viewer.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is directed to a system for providing services to viewers.
This relates to a display device consisting of a television signal reproducing device and a television receiver. BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for handling a television signal reproducing device such as a videotape player or a video disc player, and a television receiver that presents the television signal from the reproducing device to the viewer, as a total system. There is. FIG. 2 shows the structure of a system consisting of a conventional television signal reproducing device and a television signal receiver.

In FIG. 2, 21 is a television signal reproducing device;
2 is a television receiver, and 23 is a television signal. Conventionally, the television signal reproducing device 21 only reproduces and outputs recorded television signals to the television receiver 22, etc.; 21 etc. is simply presented to the viewer as a television signal. Problems to be Solved by the Invention However, if a system is constructed for the purpose of providing services to viewers using the above-mentioned television signal reproducing device and television receiver, video tape players, video disc players, etc. During periods when the television signal reproducing device is unable to reproduce or output the recorded television signal, for example, when the video software has finished or is being rewound, the television signal cannot be viewed on the television receiver. The problem is that the television receiver outputs a signal that is unsuitable for the television receiver, and the television receiver presents that signal as is to the viewer. In view of the above problems, the present invention prevents a television receiver from presenting a signal unsuitable for viewing even during a period in which a television signal reproducing device cannot reproduce or output a recorded television signal. It provides a system consisting of a television signal reproducing device and a television receiver. Means for Solving the Problems In order to solve the above problems, a system comprising a television signal reproducing device and a television receiver according to the present invention is provided.
The television signal reproducing device is provided with a function of outputting a control signal to indicate whether or not the recorded television signal is currently being reproduced, and the control signal is input to the television receiver, A function is provided to determine whether or not the signal currently being input is to be presented as a television signal, and based on this determination, signals that are unsuitable for viewing are not presented. Effect of the Invention With the above-described configuration, the present invention allows the television signal reproducing device to transmit a control signal indicating this even during a period in which the television signal reproducing device cannot reproduce or output recorded television. Since the signal is sent to the television receiver, the television receiver can determine this and prevent the display of signals that are unsuitable for viewing. EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the structure of a system consisting of a television signal reproducing apparatus and a television television receiver in one embodiment of the present invention. In FIG. 1, 11 is a television signal reproducing device, l2 is a television receiver, l3 is a television signal, and 14 is a control signal indicating whether or not the television signal reproducing device 1l is reproducing a recorded signal. ．． The television signal reproducing device l1 reproduces and reproduces the recorded television signal for the television receiver.
During output, a control signal l4 indicating this is output, and the television receiver l2 outputs a control signal l4 indicating that the television signal reproducing device l1
The human signal is presented as a television signal using the control signal from the TV. On the other hand, during a period in which the television signal reproducing device 11 cannot reproduce or output the recorded television signal to the television receiver 12, the television receiver l2 transmits the control signal l4 indicating this to the determining means. 121, and the switching means 12 is determined based on the determination output.
2 to stop presenting the signal from the television signal reproducing device ill as a television signal,
External input signals manually input via the terminal 123 from other television signal reproducing devices prepared in advance,
Simple internal signal a provided inside the television receiver
124, and present the signal to the viewer. As a result, it becomes possible to prevent signals unsuitable for viewing from being presented to the viewer. Note that it is also possible to provide functions such as selecting a backup signal to switch over or returning to the original signal. Effects of the Invention As described above, according to the present invention, in a system consisting of a television signal reproducing device and a television receiver, even during a period when the television signal reproducing device cannot reproduce or output recorded signals, the television signal can be reproduced. It is possible to prevent the receiver from presenting signals unsuitable for viewing.
