Description

DETAILED DESCRIPTION OF THE INVENTION The present invention stores terms and information regarding terms in a storage medium such as a video disk or a videotape,
The present invention relates to an electronic dictionary that allows terms and information related to terms to be arbitrarily searched from a storage medium.

In general, traditional printed dictionaries and encyclopedias include:
A plurality of headings are published on one page, and each heading is given a symbol indicating its importance, classification, etc.

Similarly, on video discs and video tapes, it is possible to record images with importance, classification, etc. written in advance. However, since conventional printed dictionaries and dictionaries have fixed notes on importance and classification, they had to be entered as additional information that is the greatest common divisor.

In contrast, the purpose of the present invention is not to permanently store additional information related to terms as output information in advance, but to store it in memory and selectively display it as output information. The purpose is to provide a dictionary.

To summarize, the electronic dictionary of the present invention includes a memory for storing additional information that is selectively displayed in relation to headwords, and an additional display means that displays the additional information together with the display contents that are fixedly displayed. It is characterized by Further, the present invention is characterized by providing a designation means for designating the type of additional information.

In the present invention, additional information is information indicating the importance of a headword, and is different from the translation or meaning of the headword. Further, the type of additional information is a rank of importance.

In the present invention, the additional display means means means that can perform additional display without damaging fixed display contents, such as adding background color, underlining, and coloring characters.

Hereinafter, the present invention will be described with reference to an embodiment of an electronic dictionary.

FIG. 1 shows an example of a display image according to an embodiment of the present invention. (1) is the first screen in alphabetical order, and (2) is the next screen. 1 is the display area where the key-entered characters are displayed, 2 is the headword, 3 is the translation display area (the translation is omitted), and 4 and 5 are the importance display bands, and by adding a background color. This is expressed, and the rank of importance is expressed by changing the hue.

Alphabet letter keys are used as operation keys.
A search key and a selection key are provided. If you input, for example, "abandon" by operating the character keys and press the search key, the screen shown in FIG. 1 (1) will be displayed. For example, four headwords and their translations are displayed at equal intervals on one screen. The selection key is used to set the rank to display the degree of importance.

FIG. 2 shows a circuit block diagram of an embodiment of the present invention. In the figure, MU is headword memory, AC
1 is the memory MU address control section, OC1 is the memory MU read control section, TB is the track number buffer, B is the entry word input buffer, VD is the video disk device, MX1 and MX2 are the mixing circuits, RF is the high frequency modulation section, DC is the decoder, TV is the television set, MM is the importance memory,
OC2 is a read control section of the memory MM, AC2 is an address control section of the memory MM, MS is a selection output control section, MB is an importance code buffer, MG is a background color signal generation section, and SB is a selection code buffer.

FIG. 3 shows part of the contents of the headword memory MU. This memory MU stores in advance the spelling of the entry word located at the beginning of each screen.

FIG. 4 shows part of the contents of the importance level memory MM. This memory MM stores in advance a code classified by rank of importance for each headword on each screen. For example, for track No. 1, the first word "a" has an importance level of 3, the third word "abandon" has an importance level of 2, and the other words have an importance level of 0. This importance level of 0 is a rank in which identification is not displayed.

Next, the operation of FIG. 2 will be explained.

First, when a desired headword is input using the character keys, the content is stored in buffer B, and the decoder
Decoded by DC, mixed circuit MX1, MX
2 and then displayed at a specific position on the screen of the television set TV. Next, when the search key is pressed, the readout control section OC1 of the memory unit searches the table in the memory MU for the headword input into the buffer B. Since the headwords are written in alphabetical order, the track number can be searched even if it is not the first headword on each screen. The corresponding track number is input into the track number buffer TB. video disc device
The VD extracts the specified track and outputs a video signal. The headword for buffer B is mixed circuit MX1
The image is then displayed in display area 1 (FIG. 1).

Meanwhile, the contents of the importance memory MM are introduced into the selection output control unit MS, and the importance code buffer MB,
The signal is input to the mixing circuit MX2 via the background color signal generator MG, and importance information is additionally displayed. When the rank of importance is specified by the selection key, the selection output control unit MS selects the priority codes read from the memory MM that are higher than the specified importance level and outputs the codes lower than the specified importance level. replaces it with 0 and outputs it to buffer MB.

As a modified embodiment of the present invention, importance memory
It is also possible to search for headwords whose importance is at a predetermined rank or higher from the importance codes stored in the MM, and to display only those headwords.

According to the present invention, unlike printed dictionaries and encyclopedias, the additional information is not fixed and can be selectively added and displayed, making it possible to provide versatility to the medium on which video is recorded. It is possible to produce an electronic dictionary suitable for the purpose and user group.

Furthermore, since the importance of the headword is displayed as additional information and the rank of importance can be selected, the usability of the electronic dictionary is improved.
