In addition, the parameters that define the video switching timing are set in a counting circuit, and the counting circuit counts based on the frame signal output for each screen scan included in the video signal, and when it counts up to a predetermined value, it instructs to switch the video. A new video is played using this signal. At the time of video switching, one of the multiple video control means is selected based on the information that determines the video switching method.
For example, when switching, the previous playback video is faded out and the next playback video is faded in.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

First, the configuration of the karaoke apparatus of this embodiment will be explained with reference to FIG.

A video playback device 1, which is a video playback means, plays back a video information storage medium such as an optical disk 1a, and a magnetic storage device such as a hard disk may also be used as the video information storage medium. In this embodiment, an optical disk 1a is used as the storage medium.

An analog/digital conversion circuit (hereinafter referred to as A/D conversion circuit) 2 quantizes analog video information obtained from the video playback device 1 and converts it into digital data, and a field memory 3 converts this digitized video information into digital data. Remember. This uses fast non-volatile memory. A digital/analog conversion circuit (hereinafter referred to as a D/A conversion circuit) 4 converts the video information read out from the field memory 3 in synchronization with a synchronization signal included in the video signal, that is, a vertical synchronization signal and a horizontal synchronization signal, into an analog signal again. The output is sent to the video control circuit 5, where it is modified and output.

The video control circuit 5 has a function of fading the video in or out by increasing or decreasing the video signal level step by step, and has the effect of creating an atmosphere that matches the slow tempo of the song. It is composed of a fader circuit 6, a wipe circuit 7 having a function of erasing an image in the horizontal direction, and a wipe circuit 8 having a function of erasing an image in the vertical direction. When switching still images by the wipe circuit 7.8, a series of stories is given to a plurality of still images to produce an effect similar to a picture-story show. In addition, D/A conversion circuit 4
A path for directly outputting the video signal obtained from the D/A conversion circuit 4 is also provided in order to output the video signal obtained from the D/A conversion circuit 4 as it is, that is, without modifying the video signal. The input section of the selector 9 is connected to the output section of the video control circuit 5. When the selector 9 selects one circuit or path from the video control circuit 5 and outputs the video signal, the lyrics information and the video signal, which will be explained later, are mixed in the superimpose circuit 10, and as a result, the monitor 11 displays The video and lyrics are displayed at the same time.

The central control unit 14 controls the selection of the output of the selector 9 and its timing. The central control section 15 has a built-in microprocessor, program ROM (read-only memory), and the like, and in addition to controlling images, it also controls performance and superimposes lyrics information.

The information that determines the video switching timing is recorded as index information of the performance information 20 that the performance playback device 15 reads from the performance information storage medium 15a, and the format in which the performance information 20 is recorded is as shown in FIG. It is shaped like this.

That is, first, the genre information of the song is stored in the genre storage section 20a, and then a plurality of parameters are stored in the parameter storage section 20b.

Furthermore, video control information indicating a modification means when switching video is stored in the video control storage section 20c, and finally song information 2 is stored.
0d is stored. Having read out the performance information 20, the central control section 14 reads out the parameters from the parameter storage section 20b and sets the values in the counting circuit 13.

Regarding the relationship between parameters and time, since the counting circuit counts each frame signal, the counted value is updated every 1/60 seconds. Therefore, when the parameter value is 60, the counting end signal is output from the counting circuit 1 second after the start of video reproduction.

On the other hand, the output of the synchronization separation circuit 12 is connected to the counting circuit 13, and when the reproduction of video information is started, only the frame signal indicating the start of one screen scan included in the video signal output from the video reproduction device 1 is transmitted. The extracted and separated signal is input, and this signal causes the counting circuit 13 to control the central control unit 1.
The counting continues until reaching the parameter value set in advance by step 4, and when the count reaches the set count value, a counting end signal is generated to the central control unit 14, and this signal is used as a trigger to execute video switching control. do.

Furthermore, the index information of the performance information includes information indicating the genre of the song, and as shown in FIG. 3, the information indicating the genre corresponding to each video is stored in the ROM inside the central control unit 14. Therefore, the central control unit 14 refers to the two pieces of information and randomly selects an appropriate video from the video information storage medium 1a having a large number of videos belonging to each genre.

An outline of the actual operation in the above configuration will be explained using the flowchart shown in FIG.
