Description

Learning device 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.

In the present invention, there is a receiving apparatus that can automatically receive and record broadcast contents without a separate timer, and repeatedly hear necessary sentences from the recorded contents.

In order to receive the lecture contents of a certain part of many airwaves and to reproduce the received contents repeatedly, the broadcasting signal is divided into the information signal and the lecture contents and transmitted to the airwaves, and the receiver equipped with the microprocessor and the recording IC is installed in the receiver. 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. In this case, the sentences can be listened to if the radio receiver matches the broadcast frequency in the same manner as the existing broadcast signal.

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 authorization 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 repetitions (107), the ASCII code of the sentence (108), the recording start signal 109, etc. This information signal 10 is a tuner 201 and analog-to-digital converter of the receiver As it passes through the 202, it is restored as a digital signal and stored in the memory of the microprocessor 203, so that special sentences can be repeated among the contents of the lecture recorded in the recording IC 204 or characters can be displayed on the display 209. have. As shown in Figure 4, the receiver is equipped with an authorization card 207, the authorization card ed password is recorded, which is to selectively receive a special signal from a number of broadcast signals and to the authorization number 101 and receiver of Figure 1 (B) When the number of the approval card 207 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 recording I.C, recording time and sentence number. In the recording start time (32), numbers such as 0, 32, 36 mean the time when the sentence starts, 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 time. The number of sentences given according to the start time 32. This is to make it easier for the microprocessor to call the statement.

From the time when the recording start signal 109 ends, the lecture contents are recorded in the recording IC 204. Since the information signal includes 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 sentences are sequentially stored while assigning the sentence numbers according to the start time 106 of the sentences in the recording IC 204. 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. In other words, 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 seconds, sentence 4 from 44 to 45 seconds It is divided into In this case, 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, since 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 time, if the sentence number is designated, the microprocessor 203 can call the address in the memory area to reproduce the sentence. Only necessary sentences can be repeatedly reproduced according to 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 repetitions 107 to be repeated have the same information as 3 and 4, the third sentence 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 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 time 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 ten times and sentence 4 ten 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 lecture date (102), which means May 26, 2000, 'English' and 'Beginner' are the signals indicating the type of learning (103) and the stage 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 numbers and repetition of sentences. That is, sentence 1 00, sentence 01 1 time 02, 1 time 03, sentence 1 once, sentence 4 04 play once, sentence 01 twice, sentence 02 twice This means repeating sentence # 03 twice, sentence # 04 twice, and repeating sentence # 10 ten times and sentence # 04 ten times. 'American ... ~ ... that again' is an ASCII code of sentences for display on the display 209. 'start' is a recording start signal, and the contents of subsequent lectures are recorded in recording I.C 204 for 45 seconds.
