BACKGROUND OF THE INVENTION
The present invention relates to a transmission apparatus including a television broadcast transmission / reception apparatus and a reception apparatus that outputs data transmitted from the transmission / reception apparatus to external video display means.
[0002]
[Prior art]
In recent years, in television broadcasting, in addition to conventional analog television broadcasting, digital television broadcasting has been spreading. With the digitization of broadcasts, the number of programs that viewers who receive and view broadcasts can select is increased compared to the past. By increasing the number of programs that can be selected, the viewer can select a program that the user wants to watch more. However, when the number of programs increases, it becomes necessary to perform a complicated operation for selecting a program to be viewed from a large number of programs when selecting a program that the user wants to view.
[0003]
In a conventional remote control device (hereinafter referred to as a remote control), it is necessary to confirm by actually watching a television screen whether the program selected by the remote control is really a program that the user wants to watch. This action causes the viewer's eyes to temporarily move away from the remote control, and if the program confirmed on the TV screen is not the program that the viewer wants to watch, move the line of sight to the remote control again to operate the remote control. You must reselect the program. If the number of programs is small, it is unlikely that the above operation of checking the screen for selecting a program is complicated. However, as the number of programs increases, the number of times that the line of sight must be transferred from the remote control to the television screen in order to confirm the selected program increases, which causes a viewer to have a sense of complexity.
[0004]
The invention described in Japanese Patent Application Laid-Open No. 5-89962 is provided with a remote control having a television broadcast receiving function independent of the television broadcast receiver, and a program channel received by the television broadcast receiving function provided in the remote control. Numbers are stored, and the remote control has a television broadcast display function. The viewer views the program displayed by the display function, and the program is stored in the remote control when the desired scene of the program is reached. The television broadcast receiver is turned on based on the channel number, the channel number is transmitted and the program is viewed, thereby reducing the power consumption of the television broadcast receiver and the television. Extends the life of picture tubes of broadcast receivers and enables viewers to view desired scenes It is.
[0005]
However, the invention described in Japanese Patent Application Laid-Open No. 5-89962 does not show a method for reducing the effort spent on the viewer's program selection accompanying the increase in the number of programs. In addition, since a viewer who takes a remote control device to watch a television broadcast does not turn off the power of the television broadcast receiver or turn down the volume every time, the present invention is effective in reducing power consumption. I can't expect. Furthermore, the television broadcast displayed on the remote control and the television program displayed on the television broadcast receiver are the same, and once the program is selected, the remote control does not make sense.
[0006]
[Problems to be solved by the invention]
When a viewer selects a television broadcast program, the conventional remote control uses a remote control to specify whether the program selected by the viewer is a program that the viewer really wants to watch. It was necessary to check the display screen of the broadcast receiver, which made the operation by the viewer complicated. As the number of television broadcast programs increases, viewers need to perform the above operations frequently, which further increases the complexity.
[0007]
