That is, according to the apparatus having the above-described configuration, when a preview program is broadcasted when a video tape is played back, the program is automatically fast-forwarded until the program starts, thereby providing convenience to viewers.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

FIG. 2 is a functional block diagram showing the essential parts of a telecast having a skip function for skipping a video tape according to an embodiment of the present invention. In FIG. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals A detailed description thereof will be omitted.

Reference numeral 31 denotes a remote control device for inputting a general execution command of the telecast. The remote control device 31 includes a skip key 31a for executing a fast forward function until the program starts, And a skip mode key 31b for setting a skip mode for executing fast forward until predetermined data for the start of the program is detected with respect to the preview program.

Reference numeral 32 denotes a VPS for detecting a program start signal in a section where a video signal is received from the video and audio signals output from the playback section 22 and outputting a predetermined code signal to a control section 30 to be described later And 33 is a first mode storage unit for storing a skip mode for skipping a preview program with a predetermined flag when the skip mode key 31b of the remote control device 31 is selected.

Reference numeral 34 denotes a signal generator for storing a predetermined code signal for a program start signal and compares the code signal inputted from the VPS detector 32 according to a control signal of a control unit 30 to be described later, Reference numeral 35 denotes a second mode storage unit for storing a program mode corresponding to a result signal from the code comparison unit 34 according to the start of the program with a predetermined flag, Is a control unit for controlling the entire apparatus of the televideo.

Next, an apparatus having the above-described configuration will be described with reference to an operation flow chart shown in Fig.

First, when a user inserts a video tape into a predetermined video deck (not shown) and then inputs a playback key using input means such as a remote controller 31 (ST301), the controller 30 controls the playback unit 22 to read the video and audio data from the video tape through the reproducing head, convert the video and audio data into electrical signals corresponding thereto, and then output the electrical signals to the switching unit 12, and the first mode storage unit 33, (ST302).

At this time, if the mode of the first mode storage unit 33 is not the skip mode, the control unit 30 controls to perform a normal playback operation (ST303, operation 304). If the mode is the skip mode, When the result signal input from the code comparing unit 34 is not input from the code comparing unit 34 (ST305), the process proceeds to ST304 Thereby performing a normal reproducing operation.

The VPS detecting unit 32 continuously detects data corresponding to the program start signal from the video signal output from the reproducing unit 22 in accordance with the reproduction control of the controller 30, And outputs the comparison signal to the controller 34. The code comparison unit 34 outputs the comparison signal to the controller 30.

On the other hand, if the result signal corresponding to the input of the program start signal is input from the code comparing unit 34 in step ST305, the control unit 30 controls the reproducing unit 22 to stop the reproducing operation It is controlled to perform the fast forward operation (ST306).

When the predetermined result signal corresponding to the input of the program start signal is input at any moment, the control unit 30 proceeds to the step ST304 to determine whether the normal Thereby performing a reproducing operation.

That is, according to the apparatus having the above-described configuration, the preview program is skipped until the program starts, thereby improving the viewing convenience of the viewer.

The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the technical scope of the present invention.

As described above, according to the present invention, when a video tape is reproduced, a preview program skip during skipping of a preview program based on a program start signal (VPS) added to an interval in which a video signal of the video tape is loaded, So that it is possible to realize tele-video having a function.
