Abstract

The screen searching control method comprises the steps of characterizing the content recorded at the present position of the video tape and recording and storing the titles and VISS position; displaying the stored titles while searching the screen; selecting one of the displayed titles; and running the video tape at a higher speed to the VISS recording position corresponding to the selected title and if it reaches the VISS position, reproducing the video tape from the VISS position.

The present invention relates to a screen search control method for high-speed screen search in a VCR, and more particularly, to a screen search control method of a VCR capable of automatically searching for and playing a desired screen (recorded program) by one-key operation. It is about.

In the conventional VCR, the screen search through fast forward (FF) or rewind (REW) uses a VHS INDEX SEARCH SYSTEM (VISS).

1 shows an example of a video tape on which a VISS signal is recorded.

As described above, when the screen search is performed on the desired scene using the video tape on which the VISS signal is recorded, the user selects the desired scene by the following two operation procedures as shown in FIG.

First, when the VISS key is turned on and the FF or REW key is pressed, the video tape is running at high speed (FF / REW), and the playback screen is output for a predetermined time whenever a VISS signal is detected from the current position. When the desired scene appears, the tape stops running and starts playing from that scene.

Secondly, when the user inputs a VlsSS number known in advance by operating a numeric key, the high speed driving of the videotape proceeds, and playback starts from when the input VISS number is detected. However, the conventional screen searching method using the VISS is inconvenient and long time required for moving the tape, since it is necessary to monitor whether or not the desired scene branch tape has been driven every time the VISS signal is detected, and from the current tape position. Since the tape recording order up to the desired scene, the VISS number must be known in advance, there is an inconvenience.

The present invention records a message (character) describing the screen contents at the VISS signal recording position, and during the FF / REW search, displays the recorded contents on the screen, so that the user can view this list and select a high speed toward a specific scene selected. It is an object of the present invention to provide a screen search control method of a VCR that facilitates a screen search operation and performs a high speed automatic search by searching and playing a desired scene by driving. Referring to FIGS. 5 to 5, the screen searching method of the present invention will be described. First, operate the function selection key on the VCR remote control to display the function selection screen as shown in (a) of FIG. 3, and select the item (title setting number) to set the title of the tape on this screen. A character input screen for recording a message is displayed. Enter the tape title and number on this screen.

The tape title is entered as text, which is implemented by adding text options to the remote control. Fig. 4 shows an example of recording a tape title, and the title of the video tape is * love song *, and the list of this song song, i.e., the contents and number of the tape as described above, is selected from the function selection key operation and the character option key operation. Fill in through

In Figure 4, the tape content and number are: 1. devotees, 2. encounters, 3. love, 4 ... and so on, and the tape title and contents are stored in memory.

It also designates the position of the current tape, which is indicated by an arrow indicating the current position on the tape content recording screen of FIG. 4, and this position information is also stored in the memory.

Through such a series of operations, the title and number of the videotape and its contents are written and stored for each item and used as screen navigation information during playback. That is, as shown in (b) of FIG. 3, turning on the key for performing the VISS function displays the contents of the tape (FIG. 4) stored in the memory in the above process.

On this screen, the user selects and enters the tape content number. For example, select number 1 "devotion." Then, when the key of playback, FF or REW is turned on, the video tape is driven at high speed while monitoring whether the VISS signal of the selected number position is detected. Since it plays back from this position, it is possible to perform high speed search of the desired scene by simple key operation. Meanwhile, as an embodiment of the present invention, when recording a tape title and each content (item), a unique code corresponding to each item is recorded together on the control track (CTL TRACK) of the video tape and the unique code is recorded. Since the code corresponds to the code corresponding to the key code on the remote controller, one-key operation can be used to perform high-speed search.

For example, the first song "Fever" in FIG. 4 records 0001 as a unique code on the control track at the beginning of the scene, and when the first key of the remote control is pressed as in FIG. 5, the code 0001 is the same as the code 0001. Coded and supplied to the VCR, the microcomputer for system control of the VCR starts from the point where the first keycode entered by the user and the unique code 0001 detected during the high-speed driving of the video tape match, that is, the point at which the first song "Dear" starts playing. By performing the playback, one-key navigation is enabled.

As described above, according to the present invention, the VCR automatically searches for and reproduces a desired scene at high speed, and is convenient. Since all operations are performed by one-key operation, VCR operation can be easily performed, and various substitutes on one tape (eg Even if a song is recorded, it is possible to perform a fast search while viewing the list of recorded contents.
