Also, in the preferred embodiment described above, it is assumed that the main memory unit 20 and the supplementary memory unit 22 are .physically separated units; however, it is possible to have a single physical memory unit, but that is divided into two areas, performing separately each function of the main memory and the supplementary memory.
With reference to Figs. 2 to 5 , there is described in detail a method for storing and outputting the visual information through the use of the caption player illustrated in Fig. 1.
Fig. 2 provides a signal pattern representing a part of a voice signal stream and a corresponding visual information calling signal stream stored in a recording medium, e.g., a cassette tape. Fig. 3 represents a storage section of a main memory unit, which stores visual
information corresponding to the visual information calling signals stored in the cassette tape shown in Fig. 2.
In Fig. 2, the voice signal stream is recorded in a right track (RT), wherein the voice signal stream contains a plurality of unit voice signals and each unit voice signal consists of a voice signal in a sentence unit, a code starting signal and a code ending signal indicating a start and an end of the voice signal, respectively, while the visual information calling signal stream is recorded in a left track (LT), wherein the voice signal stream contains a multiplicity of unit calling signals and each unit calling signal consists of a visual information calling signal corresponding to each voice signal, a code starting signal and a code ending signal indicating a start and an end of the visual information calling signal, respectively.
For instance, in Fig. 2, there are illustrated voice signals in ordinal addresses of (N-l), N and (N+l) and visual information calling signals corresponding to the voice signals, and the code starting signals and the code ending signals of the voice signal and its corresponding visual information calling signal are synchronized with each other so as to display visual information read out in response to the visual information calling signal through the display unit during its corresponding voice signal outputted through the speaker. In order to perform this function, the signal processing unit 10 shown in Fig. 1 replays the voice signal and its corresponding visual information calling signal according to the code starting signals and the code ending signals of the visual signal and the visual information calling signal.
As depicted in Fig. 3, the storage section 20a of the main memory unit 20 stores sequentially visual information that will be read out in response to the visual information calling signals in ordinal addresses of (N-l), (N) and (N+l) stored in the cassette tape as illustrated in Fig. 2. The visual information can be designated by its
corresponding visual information calling signals according to a direct or indirect designation scheme.
In the direct designation scheme, the visual information calling signal represents a memory address signal of a certain area of the storage section 20a where the visual information is stored, and the central processing unit 18 reads out the visual information stored in the certain area by using the visual information calling signal, i.e., the memory address signal, and displays it on the display unit 26 when it is coupled with the visual information calling signal replayed from the recording medium 5, e.g., the cassette tape.
Namely, a voice signal and a visual information calling signal corresponding to the Nth code starting signal are simultaneously replayed and provided to the signal processing unit 10 and, then, during the voice signal being displayed through the speaker 14, the visual information calling signal representing the Nth memory address signal is inputted to the central processing unit 18 which, in turn, reads out visual information stored in a storage area designated by the Nth memory address signal and outputs the visual information through the display unit 26, performing the caption function.
On the other hand, in the indirect designation scheme, an index signal corresponding to a visual information calling signal stored in the recording medium 5 exists in the program section 20b of the main memory unit 20 and the index signal and the memory address signal are matched to each other in a course of storing the visual information in the storage section 20a. After this operation, when the visual information calling signal is transmitted, the memory address signal of the certain storage area, where the corresponding visual information is stored, is obtained from the index signal corresponding to the transmitted visual information calling signal, thereby reading out the corresponding visual information. In case of using the
indirect designation scheme, the visual information calling signal recorded in the recording medium 5 and the memory address signal for specifying the location of the stored visual information are indirectly matched to each other through the use of the index signal; and thus, it is possible to use effectively the storage section 20a of the main memory unit 20 when updating the stored visual information with new visual information.
Fig. 4 is a flowchart illustrating a method for outputting visual information stored in the main memory unit in accordance with an embodiment of the present invention.
At step S10, as a caption player is operated, a voice signal and a corresponding visual information calling signal, recorded in the recording medium 5, are replayed in the signal processing unit 10.
Then, at step S12, the voice signal is outputted through the speaker 14 and the visual information, stored in the storage section 20a of the main memory unit 20, is read out in response to the visual information calling signal. At this time, among the visual information, basic information corresponding to the voice signal, e.g., text information identical to the voice signal, is outputted through the display unit 26, and supplementary information related to the text information is stored in the supplementary memory unit 22.
Next, at step S14, it is determined whether or not there is an input of the search key 28a of the visual information conversion switch 28. As a checking result of the step S14, if it is determined that the search key input presents, the replaying of the recording medium 5 is temporarily paused at step SI6. Also, among the supplementary information stored in the supplementary memory unit 22, information selected by the inputted search key is outputted at step S18. After completing the process at the step SI8, this
procedure goes back to the step S14 to check whether or not there presents another input of the search key 28a.
On the other hand, as a checking result of the step S14, if it is decided that there is no search key input, at step S20, it is checked whether or not the visual information calling signal corresponding to the voice signal is the last visual information calling signal replayed from the recording medium 5.
As a result of the step S20, if it is determined that the replayed visual information calling signal is not the last visual information calling signal, this procedure goes back to the step S10 and the steps S12 to S18 are repeated to continuously replay the recording medium 5, so that new voice signals and their corresponding visual information are outputted through the speaker 14 and the display unit 26, respectively.
On the other hand, as a result of the step S20, if the replayed visual information calling signal is decided as the last visual information calling signal, the process of replaying the signals recorded in the recording medium 5 is terminated.
Fig. 5 is a flowchart depicting a method for performing a conversion mode for outputting visual information stored in the main memory unit 20 and/or the supplementary memory unit 22 regardless of replaying voice signals .
When a conversion key 28b is inputted on a demand of a user at step S30, the central processing unit 18 reads out visual information stored in the storage section 20a of the main memory unit 20 to thereby output firstly basic information among the visual information onto the display unit 26 and store supplementary information among the visual information in the supplementary memory unit 22 at step S32. Then, at step S34, it is decided whether or not there is an input of the search key 28a of the visual information
conversion switch 28.
As a checking result of the step S34, if it is determined that the search key input exists, at step S36, information among the supplementary information stored in the supplementary memory unit 22, which is selected by the search key input, is outputted through the display unit 26 and this procedure goes back to the step S34 to thereby check the existence of another search key input.
On the other hand, as a checking result of the step S34, if it is decided that there is no search key input, it is decided whether or not the conversion mode operation is terminated at step S38.
If it is determined at the step S38 that the conversion mode operation is not terminated, this procedure goes back to the step S30 to read out next visual information and the whole steps are repeated again as described above.
Meanwhile, as a result of the step S38, if it is decided that the conversion mode operation is terminated, it is set to stop replaying the caption player.
In accordance with another embodiment, the search key 28a includes a further function for searching visual information on a user's demand in addition to the function for searching the supplementary information among the certain visual information. For example, among ordinal addresses of (N-l), N and (N+l) as illustrated in Fig. 3, visual information corresponding to a particular address can be searched.
As can be seen from the above, by performing the embodiments of the present invention, there are provided benefits that it is possible for the inventive caption player to download various text information such as electric books, electric study materials and electric dictionaries, i.e., data including texts, numbers, symbols and so on, and moving and still pictures through an Internet PC or a designated terminal, and to search, output
and delete the provided information. Furthermore, it is possible to input new information, so that the caption player can- implement all these diverse functions required for audio-visual educations. Accordingly, compared to the conventional caption player, the inventive caption player can effectively handle and use variously different information.
Particularly, in case of using the caption player for foreign language studies, a user does not need to carry additional study materials since it is possible to search and study information at any time due to the storage of all necessary study materials into a storage area.
As explained above, the present invention also relates to a computer readable recording medium, e.g., CD- ROM, RAM, ROM, floppy disk, hard disk, Magneto-optical disk and so forth, storing specific programs for employing the intended method. Since this course of storing the program for implementing the method is apparent and is easily inventible to those skilled in the art, detailed descriptions will be omitted.
