BACKGROUND OF THE INVENTION
The present invention relates to a power supply control device that can easily perform control of turning off power when a currently viewed program ends using program information.
[0002]
[Prior art]
As an apparatus using conventional program information, Japanese Patent Laid-Open No. 09-65270 is proposed, and an apparatus for easily recording a program by checking the date / start time / end time / channel of a desired program from guide information. An example is described.
[0003]
The configuration and operation of Japanese Patent Laid-Open No. 09-65270 will be described with reference to FIG. In FIG. 4, program information including date, channel, start time, end time, etc. is acquired from the program information signal received by the receiving device 401 using the demodulation circuit 402 and the decoding circuit 403, and the control circuit 405 receives the input. The present invention relates to an apparatus for making a recording reservation in a storage unit 404 based on a program designated by means 406 and program information.
[0004]
[Problems to be solved by the invention]
However, the present invention uses the information on the channel, date, program start and end included in the program information as a group, and is intended for reservation viewing / recording reservation of the target program. It is not intended to control the power supply at the end of the viewing program by mainly using information about the end. The present invention is similar to the off-timer function, but the existing one can be set in a fixed unit such as 30 minutes, 60 minutes, 90 minutes, etc. prepared in advance, or can be freely set in 1 minute units. However, in order to make a setting such that the power is turned off at the end of the program currently being viewed at an arbitrary time, it is necessary to calculate the time until the end of the program. Further, when the program organization is changed and the end time of the program being viewed is changed, there is a problem that it is not possible to cope with this.
[0005]
In order to solve the above problems, the power control device of the present invention includes a playback unit that plays back a program from a storage medium that stores the program and information indicating the end of the program, and a request for automatically turning off the power from the viewer. An input receiving unit for receiving a signal, a signal detecting unit for detecting information indicating the end of the program at the time of program reproduction, and a signal detection when the input receiving unit receives a request to automatically turn off the power. And a control unit that turns off the power supply of the power supply device when the unit detects information indicating the end of the program.
[0006]
The present invention is configured so that the power can be automatically turned off when the program being viewed by the viewer ends, and the program transmitted by the broadcast station superimposed on the radio wave The information signal is received by the receiving device, and the decoding circuit decodes the signal to extract program information. Here, the program information includes program content information including the broadcast date, channel, program title, start time, end time, content, and other characteristics of a program, and a tag indicating the program channel and program end. Assume that there are two types of program end information.
[0007]
The end of the program being viewed is detected from these program information, and is not limited to a predetermined fixed time unit such as 30 minutes or 60 minutes as in the past, and the end of the program being viewed from the current time There is no need to calculate the time until the time and set the off timer, and the power can be automatically turned off at the end of the program. Also, when program information transmitted from a broadcasting station indicating the end of a program is used, even if the program organization is changed for some reason (such as an extended broadcast of a professional baseball broadcast program), the end of the program is correctly detected and the power is turned off. It becomes possible.
[0008]
