ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to digital broadcast receivers. More particularly, the invention relates to a digital broadcast receiver adapted to output video signals for a desired broadcast program contained in digital signals to a video recording means.
2. Description of the Prior Art
There has been a conventional digital broadcast receiver of this kind which operates to start a VTR simultaneously with a start of a desired broadcast program, so as to output a program video and audio signal to the VTR.
However, where viewing a filmed program, it is not easy to grasp a content of the program, differently from a case of viewing a program in real time. That is, the digital broadcast signal contain EPG (Electronic Program Guide) data and program information data indicative of a concrete content of a program. Accordingly, when viewing a realtime program, the content of a program is easy to recognize through displaying the data on the screen. On the contrary, the VTR-reproduced signal contain only a video and audio signal for a program. It is therefore difficult to grasp a content of the program without reproducing program data to a certain extent.
SUMMARY OF THE INVENTION
Therefore, it is a primary object of this invention to provide a digital broadcast receiver which makes it possible to readily grasp a content of a filmed program.
According to the present invention, a digital broadcast receiver, comprises: an extracting means which extracts a video signal for a desired program from a digital broadcast signal; a generating means which generates program information for the desired program; a selective output means which selectively outputs the video signal and the program information to a video recording means; and an instructing means which instructs said video recording means to effect video recording simultaneously with an output from said selective output means.
The extracting means extracts a desired-program video signal out of a digital broadcast signal, and the generating means generates a desired-program program information. The selective output means selectively outputs the video signal extracted by the extracting means and the program information generated by the generating means. Also, the instructing means instructs the video recording means to perform video recording simultaneously with the output from the selective output means.
In one aspect of the present invention, an information amount detecting means detects an information amount of the program information, and a program information generating means generates the program information for a first predetermined time period corresponding at least to the information amount.
In one embodiment of the present invention, the information amount detected is expressed by the number of pages, and said program information generating means including a renewing means which renews a page at every second predetermined time period that is shorter than the first predetermined time period.
In another embodiment of the present invention, said generating means further includes a timing detecting means which detects timing that is prior to a broadcast start time for the desired program and associated with the first predetermined time period. An enabling means enables said program information generating means at timing detected by said timing detecting means.
In still another embodiment of the present invention, said generating means further includes a program information detecting means, and the program information detecting means detects the program information from the digital broadcast signal.
In another aspect of the present invention, an audio signal extracting means extracts an audio signal for the desired program from the digital broadcast signal. An audio signal output means outputs the audio signal to said video recording means simultaneously with an output of the video signal.
In another aspect of the present invention, the desired program is a reserved program.
According to the present invention, because program information is outputted to the video recording means, the content of a program can be easily recognized during reproduction. More specifically, a reserved program is video-recorded together with its program information by beginning video recording prior to a start of the program. This serves to readily remind the viewer of the reserved program content.
The above described objects and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
