Description

Learner using airwaves {the trainning by radio frequency}

In order to record the contents of broadcasting, the timer is set in the lecture time by using the radio with the built-in timer. When the lecture time comes, the recording switch is automatically turned on to record. Such a receiver needs to set a timer in accordance with the lecture time zone. Repetitive learning is important in the learning of foreign languages, and this batch recording method cannot repeat only the necessary parts, and can only listen to the entire recorded part repeatedly.

According to the present invention, there is provided a receiving apparatus capable of selectively receiving and recording broadcast contents without a timer and repeatedly listening to necessary sentences from the recorded contents.

In order to receive a specific part of lecture contents in many airwaves and to reproduce the received contents repeatedly, the broadcasting signal is divided into information signal and lecture contents and transmitted over the air wave, and the receiver installed in the receiver in the receiver with the microprocessor and recording IC When the number 207 of the card and the authorization number 101 included in the information signal of the broadcast signal are matched, the contents of the lecture after the information signal are automatically recorded in the recording IC of the receiver so that the user can learn regardless of the broadcast time. It is about a receiving device that can.

Fig. 1A shows a structure in which a signal is transmitted from a broadcasting station. The order of signal transmission is that the texts 11, 12, 13, 21, and 22, which are the contents of the lecture, are broadcasted after the information signal 10 is sent. At this time, the sentences are broadcast frequency to the radio receiver in the same manner as the existing broadcast signal

If you match it, you can listen. The information signal 10 is a signal in which information for displaying characters on the display 209 and a method in which the receiver's microprocessor 203 automatically records and reproduces lecture contents are recorded.

Fig. 1B shows a more detailed signal structure for the information signal 10 of Fig. 1A. The information signal 10 includes an approval number 101, a lecture date 102, a type of learning 103, a step 104 of learning, a total lecture time 105, a start time 106 of sentences, a sentence to repeat And the number of half-numbers 107, the ASCII code 108 of the sentences, the recording start signal 109, and the like. The information signal 10 is a tuner 201 and an analog-to-digital converter 202 of the receiver. When the signal is passed through, it is restored to a digital signal and stored in the memory of the microprocessor 203, so that special sentences may be repeated among the contents of the lecture recorded in the voice IC 204 or characters may be displayed on the display 209. As shown in Figure 4, the receiver is equipped with an authorization card 207, the password is recorded on the authorization card, which is to selectively receive a special signal among a number of broadcast signals and the device in the authorization number 101 of Figure 1 (B) and the receiver When the number of the approval card 107 is matched, the recording is recorded in the recording IC 204 for the entire lecture time 105 after the recording start signal 109.

Fig. 3 shows the relationship between the recording IC, recording time and sentence number. In the recording start signal 32, numbers such as 0, 32, 36, etc. represent the starting time of the sentence, and numbers 0, 100, 151 of the recording IC memory 멥 31 indicate the starting address where the sentences are stored, and the sentence number 30 indicates the recording. The number of sentences given according to the start time 32. This is to make it easier for the microprocessor to call the statement.

The contents of the lecture are recorded in the recording IC 204 from the end of the recording start signal 109. Since the information signal includes the information about the start time 106 of the sentences, the microprocessor 203 can distinguish the sentences. When the recording start signal 109 is input, the timer 208 of FIG. 2 is reset to '0', and the recording IC 204 is sequentially stored while assigning sentence numbers according to the start time 106 of sentences. If the total lecture time is 45 seconds and the start time 106 of the sentences contains information such as 0, 32, 36, 40, 43, the total number of sentences is five. That is, sentence 0 from 32 to 0, sentence 1 from 33 to 35 seconds, sentence 2 from 36 to 40 seconds, sentence 3 from 41 to 43, sentence 4 from 44 to 45 seconds It is divided into At this time, sentence 0 is stored in memory areas 0 to 99, sentence 1 is stored in memory areas 100 to 150, and sentence 4 is stored in addresses 201 to 215. That is, the microprocessor 203 knows the memory address corresponding to the time of the sentence and knows the number of the sentence corresponding to the sentence. Therefore, if the sentence number is specified, the microprocessor 203 can call the address in the memory area to reproduce the sentence. That is, it is possible to repeatedly reproduce only necessary sentences in accordance with the sentence number to be repeated and the number of repetitions 107 included in the information signal 10. If the sentence number and the number of repetition (107) to repeat the same information as 3,4, sentence 3 can be repeated four times.

The lecture date 102, the type of learning 103, the step 104 of learning, and the code 108 of the sentence are ASCII codes for display on the display 209.

The following is an example of an English class.

There are five sentences in total. English sentences 1,2,3,4 need to be repeated listening and sentence 0 is an explanation part. The total lecture time is 45 seconds, the start time of sentence 1 is 32 seconds, the start signal of sentence 2 is 36 seconds, the start time of sentence 3 is 40 seconds, and the start time of sentence 4 is 43 seconds.

The information signal 10 when playing the entire lecture once, repeating sentences 1, 2, 3, 4 twice, sentence 2 10 times and sentence 4 10 times

'10000'-'20000526'-'English'-'Beginner'-'0045'-'000-032-036-040-043'-0001,0101,0201,0301,0401,0102,0202,0302,0402, 0210,0410 '-' American ... ~ ... that again '-' start '

10000 is an authorization number, and if it matches the contents of the authorization card 207 installed in the receiver, the data after the authorization number is stored in the memory 210 by the microprocessor 203. 20000526 is the date of the lecture (102), which means May 26, 2000. "English" and "Beginner" are the signals indicating the type of learning (103) and the level of learning (104), and 0045 is the total lecture time (105). This means 45 seconds. 000-032-036-040-043 represents the recording time of sentences. 0001,0101,0201,0301,0401,0102,0202,0302,0402,0210,0410 means number and repetition of sentences. That is, once sentence 00 is played, sentence 01 is played once, sentence 01 is played once, sentence 03 is played once and sentence 04 is played once, sentence 01 is played twice, sentence 02 is played twice and sentence 03 is played twice. This means repeating sentence 04 twice and repeating sentence 02 ten times and sentence 04 ten times. 'American ... ~ ... that again' is the ASCII code of the sentences for display on the display 209. 'start' is a recording start signal, and the contents of subsequent lectures are melted and recorded in the IC 204 for 45 seconds.

The lecture date 102, the type of learning 103, the step 104 of learning, and the ASCII code 108 of the sentence are information signals for display on the display 209 while the sentence is being reproduced through the speaker 206. The display 209 can be displayed in text.

By using the airwaves to learn foreign languages, you can conveniently receive daily lectures at home, eliminating the wasted time and inconvenience of having to go to the school, etc., depending on the type of approval card, such as English, Japanese, Beginner, Intermediate, etc. Record only the content you need, but it will be automatically recorded without the need for special device manipulation. Because the microprocessor can implement the function of storing and repeating the sentences, it is possible to easily listen to the most important sentences necessary in foreign language learning and maximize the learning effect by displaying the sentences through the display.
