Abstract

PURPOSE:To improve handleability by discriminating a desired program type PTY from the networks of a present station or the other included in the RDS data of a reception station and automatically sound-interrupting the valid station of the network. CONSTITUTION:When the SEL button of an operation part 9 is pushed, the PTYs are displayed at a display part 8 and updated successively in the order of the numbers of the PTYs and an operator performs selection while looking at the display. When the desired PTY is present and a preset button is pushed, a preset number pertinent for the PTY displayed at the point of time is stored in a second memory 10b. A control part 11 stores the information of the other network included in the RDS data sent from an RDS decoder 7 in a first memory 10a. When a PTY code in the RDS data coincides with the PTY for which interruption is reserved in the control part 11, scanning is executed by the frequency list of the pertinent network among the stored frequency lists. Then, when the valid station is detected, voice interruption is performed from the other station and other sources and the desired program is received.

Description

Detailed Description of the Invention

[0001]

The present invention relates to RDS (Radio Data Sys
tem) RDS receiver capable of receiving broadcast.

[0002]

2. Description of the Related Art RDS data is transmitted as a series of 104-bit elements called groups, as shown in FIG. Each group can be further decomposed into four by 26-bit elements called blocks. Each block consists of 16-bit information and 10-bit check word.
In addition, the content of the information of each group data is defined by its position, and the 16 bits of the first block is always a PI code (Program identification code), which is called program identification information, and the broadcast is of any country. It also includes information such as whether the same broadcast is being made in other countries.

The first 5 pits of the second block are the group type of the group, and a code for identifying what is sent in the data sent after that, the next 1 bit is TP (traffic program code), The following 5 bits are the PTY (Program type code) of the own station and represent the program content as shown in FIG. 12, and include, for example, news, sports, education, pops, rock music and the like.

Remaining bits of the second block, third and fourth
The contents of the block data are specified for each group type. Among this data, the third block has an AF code (frequency information of other station), which conveys frequency information of another station broadcasting the same program as the station being broadcast. I understand.

Of the above group types, the group type 14A (Type 14A group) is Enhan as shown in FIG.
This is ced Other Networks information, which conveys information of other networks (displayed as Other Networks; ON), and the situation of PTY of other stations is also included therein.

As a method of using the PTY code, for example, JP-A-3-34630 and JP-A-63-136 are available.
For example, there is one disclosed in Japanese Patent No. 829. JP-A-3-34
The one disclosed in Japanese Laid-Open Patent Publication No. 630 is to switch the PTY code to a station of the next highest PTY code if there is no station of the highest PTY code by conducting a search with priorities set in advance. Further, in the one disclosed in Japanese Patent Laid-Open No. 63-136829, broadcasting stations obtained by sweeping are classified and stored in memory according to PTY codes, and the PTY codes are collectively displayed to clarify the user audible type. It is something to do. All of these are the PTY of the broadcasting station's own station obtained by the sweep.
It is an invention using a code.

[0007]

In the conventional RDS receiver, the PTY of the broadcasting station's own station obtained by the sweep as described above.
Since the code is used, for example, when "I want to hear the news" or "I want to listen to the classical music", if the desired genre cannot be received by the sweep, it was necessary to issue a sweep command again or again after a certain time. . Also TAPE and C
After switching to D etc., there is a problem that the user is forced to perform a very troublesome operation of switching to FM mode and sweeping the desired genre.

The present invention has been made to solve the above-mentioned problems, and when listening to a relatively unwilling FM broadcasting station or another source, the FM station of the desired PTY broadcasts. Once started, the aim is to obtain a device that can automatically receive this broadcast.

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an RDS receiver of the present invention, in which 1 is an antenna, 2 is an FM tuner that inputs the signal of the antenna 1 and outputs an FM demodulated signal, and 3 is a demodulated signal of the FM tuner 2, which is an L or R signal. MPX circuit to separate into 4
Is an amplifier for amplifying the output signal of the MPX circuit 3, and 5 is a speaker.

Reference numeral 6 is a PLL (phase locked loop) for stabilizing the local oscillation frequency in the FM tuner 2, and reference numeral 7 is an RDS decoder for demodulating an RDS modulation signal extracted from the demodulation signal of the FM tuner 2 and decoding RDS data. . 8
Is a dot matrix type display, 9 is an operating unit, 10
Is a storage unit having a first memory and a second memory,
It controls the first storage means and the second storage means, respectively. 11
Controls each circuit according to a program written in advance by the control unit.

FIG. 2 is a front view of the RDS receiver, which is provided with the display unit 8 and the operation unit 9. This operation unit 9 has a “P
"TY" button, "SEL (SELECT)" button, "P1"
"P2" ... Preset buttons are provided.

FIG. 3 and FIG. 4 show flow charts of the main program written in the control unit 11.
The following is a description based on this.

First, the control section 11 constantly monitors whether or not the operation section 9 is operated. When the PTY button is pressed, the pressing time is counted (S-1, S-2). If it is less than 1 second, the "PTY preset mode" is entered and the receiving station's P
Display TY and reset the timer (S-3, S
-4).

Next, when the SELECT button is pressed, for example, the PTY display is cyclically updated according to the PTY numbers shown in FIG. 12 (S-5, S-).
6). No. 15 Other Music in FIG. 12 (for example, OTHER
After MU) is displayed, it returns to No. 1 and becomes NEWS. In this way, the images are sequentially displayed. The purpose of this sequential cyclic update is that it is complicated for the user to voluntarily enter 10 or more types of PTYs, so that they are sequentially displayed on the display unit 8 so that the operator can see and select the display. is there.

Therefore, the operator sees this display and pushes the preset button if the desired PTY is found. When the preset button is pressed in this manner, the code corresponding to the PTY currently displayed is stored in the memory area of the second memory 10b corresponding to the pressed preset number (S-7, S). -8). After entering the PTY preset mode and resetting the timer, if neither the SELECT button nor each preset button is operated for 5 seconds or more, the PTY preset mode is released and the normal reception mode is set, and the station currently receiving is continuously received (S- 9-S-11).

The PTY code stored in S-7 and S-8 is P determined by RDS data.
It need not be a TY code. This is intended to allow the RDS receiver side to set a PTY other than the RDS data in advance. For example, the RDS data does not have a PTY of "MUSIC", but the receiver side specifies 0101-01111. It can also be set at once.

On the other hand, when the PTY button is pressed for 1 second or longer, the PTY interrupt reservation mode is set and "PTY PRI" is set.
“O” (PTY PRIORITY: meaning of PTY priority mode) is displayed, and at the same time, the PTY set at the time of the previous PTY interrupt reservation is displayed and the timer is reset (S-21, S-22). Next, when the SELECT button is pressed, if it is less than 1 second, the displayed PTY
Are sequentially and cyclically updated (S-23 to S-2
5).

When the SELECT button is pressed for 1 second or more, it means that the interrupt reservation is made in the displayed PTY.
The interrupt waiting mode is entered and the frequency of the receiving station is displayed (S
-26 to S-28). At this time, "PTY PRIO" is also displayed, and this serves as a means for notifying the display that an interrupt is waiting.

When the PTY button is pressed in this state, the interrupt waiting mode is released and normal reception is resumed. At this time, "PTY
The display of "PRIO" is also canceled (S-101 to S-1.
03).

When the PTY button is not operated, the control unit 1
1 continues to collect information on other networks contained in the RDS data sent from the RDS decoder 7, and stores the frequency in the first memory 10a for each network (PI) (first storage means). Then, when the PTY code in the information of the other network matches the PTY code for which the interrupt reservation is made, the voice is muted and the network stations stored up to that point in the first memory 10a are scanned. If there is an effective station, the reception is switched to that station to display the frequency and the muting of the voice is canceled (S-104 to S-110).

The above "effective station" refers to a case where the electric field strength is a predetermined value or more and the RDS data is correct.

At this time, "O" is added to the end of "PTY PRIO".
By turning on the display of "N" and setting it to "PTY PRIO ON", the fact that an interrupt has actually occurred is indicated on the display (S
-109). Even if the PTY code of another network and the PTY code of the interrupt reservation are found to match, if there is no valid station in the scan of the network, the original receiving station is returned to (S-107, S-111).

On the other hand, when the preset button is pressed in the "PTY interrupt reservation mode", the PTY stored in the memory area of the second memory 10b corresponding to the preset number is displayed (S-31, S). -32). If this preset button is used, it is not necessary to cyclically call PTY with the SELECT button, and PTY can be called easily. Therefore, it is very convenient to preset the PTY that is frequently used by the above method. PTY called by the preset button, select 1 SELECT button
When pressed for more than a second, the interrupt reservation is completed, and the interrupt waiting mode is set (S-24, S-26, S-27).

If the SELECT button or each preset button is not operated for 5 seconds or more after the timer is reset after entering the PTY interrupt reservation mode, the PTY interrupt reservation mode is canceled and the normal reception mode is set, and the station currently receiving is switched. Continue to receive (S-33 to S-35).

Here, the first storage means (using the first memory 10a) and the second storage means (second memory 10).
The relationship of (using b) is shown in the memory map of FIG. The frequency data (AF list) of the receiving station or the frequency list of another network sent by the group type 14A (Type 14A group) is stored in the first storage means. It should be noted that the memory content is not limited to the frequency list, and other data may be set.

The preset channel is the same as the data holding method of the receiving station for each channel. Since this preset channel is preset by the user's will, it may be a non-RDS station or may not be preset with necessary contents. Therefore,
Group type 14A (Type 14Agr as RDS receiver)
In order to memorize the information obtained from Oup), it is better to set as much as possible in a memory area called a pool store which is a part of the first storage means accompanied by a network frequency list and the like.

Example 2. Next, a second embodiment of the present invention will be described. FIG. 6 is a block diagram of an RDS receiver according to the present invention. Items 1 to 11 are the same as those described with reference to FIG. Reference numeral 12 is an AM tuner for inputting a signal from the antenna 1 to obtain an AM detection output, 13 is a CD section, 14 is a tape section, 15 is a tape section 14, a CD section 13, an AM tuner 12, and an FM MPX.
3 is a source switching unit for inputting a signal from 3 and switching the output to the amplifier 4 from the input. Reference numeral 16 denotes an AM PLL unit that controls the local excavation of the AM tuner 12.

FIG. 7 is an example of a front view of the RDS receiver, which is provided with the display 8, the operation section 9, the tape insertion opening of the tape section 14, and the like. The operation unit 9 is provided with a "SET" button not shown in the embodiment of FIG. FIG. 8 and FIG. 9 show flow charts of the program of the main part written in the control unit 11. The following is a description based on this.

First, the control unit 11 constantly monitors whether or not the operation unit 9 is operated. When the PTY button is pressed, "P
“TY PRIO” is displayed and the pressing time of the PTY button is counted (S-201 to S-203). If the pressing time is longer than 1 second, a plurality of PTYs (there may be one) at the time of the PTY interrupt reservation made last time are sequentially displayed on the display unit 8 and then "PTY" is displayed using the dot matrix display.
SET? Is displayed (S-204, S-205).

On the other hand, if the PTY button is pressed for less than 1 second, the timer is reset and the preset button and
Monitor the operation of the CT button (S-211, S-212, S
-214). When the preset button is pressed, after the PTY stored in the memory area of the second memory 10b corresponding to the preset button is sequentially displayed on the display unit,
"PTY SET?" Is displayed (S-212, S-2
13, S-205). When the SELECT button is pressed, for example, a PTY as shown in FIG. 12 is pressed each time the SELECT button is pressed.
The PTY display is cyclically updated according to the number of, and the timer is reset each time (S-214-
S-216).

If neither the preset button nor the SELECT button is pressed for 5 seconds or longer, the PTY interrupt reservation mode is released (S-212, S-214, S-231, S-23).
2). Also, after pressing the SELECT button, the PTY button
If the button is not pressed for more than a second, the PTY interrupt reservation mode is similarly canceled (S-217, S-241, S-24).
2). When the PTY button is pressed, the pressing time is counted, and if it is 1 second or less, it is determined whether the PTY currently displayed is set as an interrupt target. In the case of a target, as a target (S-21
7, S-218, S-220 to S-222), and SE
Continue monitoring the LECT button.

Whether or not the displayed PTY is set as an interrupt target is notified to the user by simultaneously displaying a "*" mark or the like at the head or end of the displayed PTY. S
If the PTY button is pressed for more than 1 second after the ELECT button is pressed, the PTYs that are set as interrupt targets at that point are displayed in sequence and then "PTY SET?"
Is displayed (S-214 to S-219, S-205).

When "PTY SET?" Is displayed,
The timer is reset to monitor the operation of the preset button and the SET button, and when the preset button is pressed, the contents of the memory area of the second memory 10b corresponding to the preset button is cleared to set the PTY currently set. The pattern is stored in the memory area and the timer is reset again (second storage means) (S-251 to S-254). S
When the ET button is pressed, it enters the interrupt waiting mode,
The frequency of the receiving station is displayed while the display of “TY PRIO” continues (S-255 to S-257). If neither the preset button nor the SET button is operated for 5 seconds after the timer is reset, the PTY interrupt reservation mode is released (S-261,
S-262).

If the PTY button is pressed in the interrupt waiting mode, the interrupt waiting mode is released and "PTY PRI"
The "O" display is canceled (S-301 to S-303). In the interrupt waiting mode, the control unit 11 continues to collect information of its own station or other networks contained in the RDS data sent from the RDS decoder 7, and stores the frequency in the first memory 10b for each network (PI). (First storage means).

Then, when the PTY code in the information of the own station or other network matches the PTY for which the interrupt reservation is made, the mode of the source switching unit is confirmed, and in the case of the FM mode, it matches the PTY of the interrupt reservation. If the selected station is its own station, "PTY PRIO ON" is displayed (S-311).
~ S-314). If it matches the PTY of another network, the audio is muted and scanning is performed according to the frequency list (AF list) of that network (PI) stored in advance, and if there is a valid station, tuning is performed to the valid station. At the same time as receiving, the frequency and "PTY PRIO
“ON” is displayed to cancel the audio mute (S-31
3, S-321 to S-326). If there is no valid station,
While canceling the audio mute and receiving the current station, PTY
Continue the interrupt wait mode (S-323, S-32
7).

When the PTY of the own station or another network matches the PTY of the interrupt reservation, and if the mode of the source switching unit is other than FM, scan according to the AF list of the PI station that matches the PTY of the interrupt reservation. If there is an effective station, the effective station is tuned and received, and then the source switching unit 15 switches to FM and "PTY PRIO ON" and the frequency of the effective station are displayed (S-312, S-331).
~ S-334). Although not shown, when switching sources, mute is applied for a short time in order to prevent switching noise. When the scan is performed and there is no effective station, the interrupt waiting mode is continued with the current source (S-332).

[0048]

As described above, according to the present invention, a desired PTY can be identified from the own station or another network included in the RDS data of the receiving station, and the effective station of the network can automatically be interrupted by voice. Since it is configured as described above, there is an effect that it is not necessary to listen to other stations and other sources that are unwillingly indefinitely even though the desired program has started broadcasting.

Further, since a plurality of desired programs can be reserved by a series of operations, the reservation can be simplified, and there is a possibility that a desired program is interrupt-reserved, but no interrupt actually occurs. But
In this case, you can make reservations for many desired programs,
Most of these problems are eliminated.

Further, since the display means is provided, the interrupt waiting mode and the interrupting state are displayed on the display section, so that it is possible to prevent the duplication error of the interrupt reservation and the uncomfortable feeling at the time of the interrupt.

Further, since the preset button is provided, the operation of interrupt reservation of a desired PTY such as a frequently used PTY is facilitated.

Further, since the combination of PTY for interrupt reservation is patterned and preset, the operation of interrupt reservation is facilitated.
