2. Description of the Related Art As audio devices have been digitized, audio data has been digitally recorded on a CD or MD optical disc from a cassette tape recorder which handles analog data, which has been widely used as an audio player for reproducing various types of audio. Digital audio players have become widely used. In recent years, DVDs with audio data recorded on DVDs
Audio players have also been used. Thus, the so-called package media in audio devices has been digitized and diversified.

[0003] Further, in these digital audio players, audio data to be recorded is compressed and recorded by various methods. Among them, in recent years, compression and recording of audio data in MP3 format have been performed. Is widely practiced. According to this technology, one C
More than 100 songs can be recorded on a DR or a CD-RW, and can be carried and listened to, for example, with an MP3-compatible CD player in a vehicle audio device. In particular, with the development of the Internet in recent years, various types of audio data have been distributed over the Internet for free or for a fee. Users can download this data and record it on a CD-R or the like for use. Have been done.

As an audio device, besides an audio player for reproducing the above-mentioned audio recording medium,
Radio audio broadcast receivers have been widely used in the past, but in recent years digitization by satellite broadcast has been particularly advanced, and CS digital audio broadcasts are currently being broadcast on more than 100 channels. Also, B
S broadcasts have also been digitized, and among them, audio broadcasts are being broadcast on multiple channels. Further, multi-channel broadcasting by digitizing terrestrial AM broadcasting and FM broadcasting is also planned. In particular, more digital audio broadcasting will be performed in the future, such as a plan of satellite broadcasting suitable for reception at a moving body such as a car is being advanced in each country. In addition, these digital audio broadcasts not only listen to the broadcast when they are received, but also record digital audio data transmitted by the broadcast on a digital data recording medium due to the recent development of various digital audio players as described above. It is also used.

[0005]

As described above, in recent audio players using audio recording media such as CDs, MDs, and DVDs, due to the progress of the compression technology of the audio data recorded on these media, one is required.
A large number of songs are recorded and used on one recording medium. In addition to commercially available audio data recorded on these recording media, various types of audio data such as those obtained by recording various broadcasts such as CS digital broadcasts and those downloaded from the Internet can be used.
It is also widely practiced to record a large amount of data by compressing it with P3 or the like, and to listen to this through an audio player. In addition, audio broadcasting has been digitized in CS, BS, terrestrial waves, and the like, and broadcasting is being performed on an extremely large number of channels, or the broadcasting is about to be performed.

There are some songs which are recorded in such a way that they are compressed and used by the audio system at any time. In that case, you can listen to the song repeatedly, especially if you like it, but in many cases it is recorded on an audio recording medium that can be used at any time in this audio system I want to watch a song other than the song. Therefore, switching to a channel that broadcasts a song other than the song currently being listened to is often performed.

[0008] As described above, when a large number of audios can be selected, the same music is often selected in particular. For example, the first music in the current hit chart is broadcast on many channels, Often found on your own CD. At this time, when it is not preferable to listen to the same music many times, the user switches to another channel, and the operation is frequently performed. Such an operation is particularly unfavorable in terms of safe driving, particularly in the case of a vehicle audio device, in which the person handling the device is often a driver.

Therefore, the present invention has a receiver such as a broadcast receiver for receiving multi-channel broadcasts such as digital broadcasts, and is connected to an audio player for reproducing an audio recording medium containing a large number of songs. It is an object of the present invention to provide an audio device capable of selecting and receiving a channel broadcasting a song not recorded on an audio recording medium.

Digital audio broadcasting [DAB (Dig
ital Audio Broadcasting)]
Includes a plurality of audio data in which audio signal data of a predetermined program is inserted by frequency multiplexing, and program additional information data in which correspondence between the program and the audio data and various information are recorded. It receives a multiplex broadcast signal, demodulates a frequency multiplex signal inserted in a data field corresponding to a program specified by a user separately, converts the signal into an audio signal, and outputs the signal.

In this digital audio broadcast receiver 9, a radio wave of a digital audio broadcast broadcasted on 100 channels or more is received by an antenna 1, and the received radio wave is demodulated by a digital broadcast RF unit 2 to demodulate an RF signal. The signal is output to the digital broadcast decoding unit 3, where the program additional information data 4 and the audio data 5 are separated from the digital audio data, and these are respectively decoded, and the program additional information data 4 is controlled. The audio data 5 is captured by the unit 8 and output to the amplifier 29 of the head unit 28 via the digital-to-analog converter 6.

As schematically shown in FIG. 5A, the format of data used in digital audio broadcasting is that data of channel 1, data of channel 2,... The n data are transmitted, and each channel data includes audio data in which music data is recorded and program additional information data. As shown in the figure, the program additional information data includes a program name, a program ID, a title, an artist, an elapsed time, and the like.
C (error detection code using a cyclic code) is added.

On the other hand, in the illustrated embodiment, the audio player 10 connected to the head unit 28 of the audio player is a disk such as a CD-R or CD-RW capable of recording more than 100 songs by compressing in the MP3 format or the like. 1 is reproduced, and the disc 1 is applied to a player 12, rotated by a motor 13, and read by a pickup 14 moving in a radial direction of the disc to read music data recorded at a predetermined position. I can do it.

The motor 13 and the pickup 14 are controlled by a servo driver 16. The servo driver 16 receives a user's music selection instruction input from an external operation unit 33 and a music selection change instruction from the system controller 24 of the head unit 28. Thereby, the operation of the pickup 14 can be controlled, and an arbitrary music can be selected.

The RF signal captured by the pickup 14 is amplified by the RF amplifier 15 and is input to the compressed data decoding unit 17. Here, for example, information such as a song title and an artist name of a recorded song is recorded from a portion where the information of the recorded song is recorded in each audio recording medium, such as ID3 tag information in data compressed and recorded in the MP3 format. The music additional information data 18 and the audio data 19 recording the music data are separated and decoded. The operation of the compressed data decoding unit 17 is controlled by the control unit 21 and the compressed audio data 1
9 is a digital-to-analog converter 20 similar to the conventional device.
To the amplifier 29 of the head unit.

In the data compressed and recorded in the MP3 format or the like, for example, as schematically shown in FIG. 5B, audio recording on a CD-R, CD-RW, DVD, HDD, memory stick, etc. On the medium, compressed audio data corresponding to each music and music additional information data are recorded at positions corresponding to each audio recording format,
As shown in the figure, the song additional information data of each song includes a title, an artist, an album, a genre, a release year, and the like.

In the head unit 28 shown in FIG. 1, the system controller 24 outputs a control signal to the control unit 8 for controlling the operation of the digital audio broadcast receiver 9 and controls the audio player 10 as described above. By outputting the control signal to the section 21, the whole can be operated as one audio player in a unified manner. In addition, the amplifier 29
The audio signal from the digital-to-analog converter 6 of the digital audio broadcast receiver 9 and the audio signal from the digital-to-analog converter 20 of the audio player 10 are selectively inputted, and any one of the audio signals is selected. Output can be made from the speaker 30. When a CD changer or the like is further connected to the audio player, these audio signals can be selectively input.

The system controller 24 of the head unit 28 is provided with a broadcast music information memory 37 for each channel. From the part recorded in the additional information data 4 or separately from the electronic program guide (EP
By receiving G), this is acquired and recorded via the control unit 8.

The system controller 24 is provided with a broadcast music information search unit 38, and among the currently broadcast channels, at least a channel that broadcasts at least a music that the user does not want, or particularly Channels or the like that broadcast songs of artists preferred by users can be searched from this data.

Further, the head unit 28 is provided with an audio recording medium recording music information memory 35. When an audio recording medium such as a CD-R is loaded in the audio player 10, the audio data is stored in the head unit 28 via the control unit 21. The artist and song title of the song recorded on the audio recording medium are read for all songs and recorded.

The system controller 24 is provided with a recorded music search section 36, which stores the music broadcast on the channel selected and received by the digital audio broadcast receiver 9 as described later. , Or whether there is a predetermined number or more of songs by a particular artist.

In accordance with an instruction from the system controller 24, the recorded music retrieval section 26 retrieves that the music broadcast on the currently selected channel is a music that exists in the audio recording medium recorded music information memory 35. In some cases, the broadcast music information search unit 38 searches the broadcast music information memory 37 for each channel for music to be broadcast on the next channel, for example. Next, it is again searched whether this song is a song recorded in the audio recording medium recorded song information memory 26, and finally a channel for broadcasting a song not recorded in this memory is detected. The signal is output to the channel selector 7 and received.

As described above, when it is found that the song broadcast on the currently selected channel is a song existing in the audio recording medium information memory 35, the broadcast song information memory 37 for each channel is retrieved. All recorded songs and audio recording media recorded song information memory 3
5 and extracts all channels broadcasting songs not recorded, and among them, various channels such as channels broadcasting songs of the user's favorite artist. It is also possible to perform a process of selecting an arbitrary channel according to the selection criterion and instructing reception selection of the channel.

In the audio device having the above-described block configuration, the audio device can be sequentially operated, for example, according to an operation flow as shown in FIG. This will be described with reference to the examples shown in FIGS. In the digital broadcast receiving channel selection process of FIG. 2, the operation is started from a state in which the power of the audio apparatus is turned on (step S1), and the audio player 10 is checked immediately in preparation for the subsequent operation of the digital broadcast receiver. It is determined whether or not the audio recording medium has been inserted into the player (step S2), and when not inserted, this operation is repeated to wait for insertion.

At this time, there are various types of audio recording media, and as described above, CD-R, CD-R
W, DVD, memory stick, etc., and a removable hard disk such as a card type may be used. In addition, a fixed hard disk drive is mounted in advance in the audio device, and audio can be recorded on this. This includes cases where it is possible to do so. In this fixed hard disk, there is no operation for inserting the audio recording medium into the player in step S1. Therefore, in this operation flow, the audio recording medium is substantially inserted into the player. And the process proceeds to the next step S3.

In step S2, when it is determined that the audio recording medium has been inserted into the player, the recording music additional information is obtained (step S3).
Thereafter, this is recorded in the music information recorded on the audio recording medium (step S4). This is in the example of FIG.
The system controller 24 of the head unit 28 controls the audio player 10 to
The music additional information data 18 separated in step 7 is fetched via the control unit 21 and the music information
5 by recording. This memory can be operated in the same manner even if it is provided on the audio player side.

In this way, the information of the music recorded on the audio recording medium inserted in the audio player 10 in advance is taken in and recorded. For example, a CD-R can be reproduced in this audio device. In addition to a CD player, when a memory stick that records audio is inserted into a card slot and when a lot of audio recording media such as a CD changer are mounted, the audio device is turned on. At that time, the information of the music recorded on all of these audio recording media is taken in separately for each audio recording medium and recorded in the memory.

If the audio recording medium is removed during use of the audio device, all the music information on the removed audio recording medium is deleted. The recorded music information of each audio recording medium pre-recorded as described above is used for the operation of digital broadcast reception in the present invention as described later in this audio device. It can be arbitrarily displayed on the image display device 31, and can be used by the user when selecting the music when the audio player 10 is operated.

Next, it is determined whether or not digital broadcast reception has been selected (step S5). If reception has not been selected, the process waits until a selection is made. When this selection is made, information on the music currently being broadcast on each channel of the digital broadcast is obtained (step S6). As described above, this information can be used when it is included in the program additional information data in the broadcast of each channel, and when the electronic program guide (EPG) is being broadcast, the information can be used from here. Can be captured. The data captured in this manner is recorded in the broadcast guide information memory 37 for each channel in the head unit 28 in FIG. 1 (Step S).
7). This memory can be operated in the same manner even if it is provided on the digital audio broadcast receiver 9 side.

Thereafter, the digital audio broadcast receiver 9
It is determined whether or not the same song as the song being broadcast exists in the audio recording medium recorded song information memory 35 for the channel currently selected for reception (step S).
8). At this time, the information of the currently broadcasted song can be obtained directly from the program additional information data 4. However, in FIG. 34.

As a result of the determination in step S8, when the same music as the music of the detected channel exists as the recorded music,
A channel that broadcasts a song that is not in the recorded song memory is selected (step S13). In the selection, when it is detected that a song to be broadcast on the channel selected for reception exists as a recorded song, the next channel is immediately selected, and the channel-by-channel broadcast song information memory 37 is searched for that channel. By repeating the operation of performing the same check, it is possible to search for a channel broadcasting a song that is not recorded. If it is determined in step S8 that the music on the detected channel does not exist as a recorded music, the channel selection is not changed.

In the digital broadcasting that is currently being broadcast, for example, CS audio broadcasting has more than 100 channels. Therefore, it is almost impossible to record music broadcast from each channel for all channels. In any of the selections, a channel on which a song not recorded is broadcast is selected.
In this manner, a channel is detected in which it is detected that the same song as the song being broadcast does not exist in the recorded song information memory (step S10).

Further, when a song broadcast on the currently selected channel is a song recorded in the audio recording medium recorded song information memory 35, a channel broadcasting a song not recorded is searched. In some cases, as mentioned above,
Check each channel in turn to receive such channels when they are found,
As described above, when it is found that the music being broadcast on the channel currently selected for reception is a music existing in the audio recording medium information memory 35, all the music recorded in the broadcast music information memory 37 for each channel is searched. Is compared with the song recorded in the audio recording medium recorded song information memory 35, and all channels broadcasting songs not recorded are extracted. The user can select an arbitrary channel according to various selection criteria, such as a channel that broadcasts, and instruct reception selection.

In practice, the selection of the recorded songs is performed, for example, as shown in FIG. That is, the music recorded on the audio recording medium shown in FIG. 1 is an artist and a music title as shown in FIG. 4A, and this data is stored in the audio recording medium recorded music information memory 35 of FIG. Be recorded. Also, the songs on the currently broadcast channel are artists and song titles as shown in FIG. 2B, and this data is recorded in the broadcast song information memory 37 for each channel in the embodiment shown in FIG.

In such a case, for example, if the currently broadcast song or the next broadcast song is “Love Machine” of Morning Musume when two channels are currently selected, this song is already the same. Since the song is recorded as shown in FIG. 7A, another channel is selected. At this time, the next three channels are searched according to the channel search method. .
Since the song broadcast on these three channels is "Time Limit" by Hikaru Utada, it can be seen that this song is also recorded as shown in FIG. Next, when the channel 4 is selected, since "Hayatochiri" of Hikaru Utada broadcast here does not exist in the recorded music, this channel is received. When two channels are first received, the next channel to be selected is one.
If the channel is a channel, since "TSUNAMI" of Southern All Stars broadcast here does not exist in the recorded music, this channel is immediately selected as the reception selected channel.

In the above-described example, an example is shown in which the search is performed with the channel being forwarded. However, for all the currently broadcasted songs shown in FIG. 4B, the songs shown in FIG. Or not at once, and it is also possible to select an appropriate channel from all the receivable channels by an arbitrary criterion.

When the reception channel is selected and reception is started in this way, it is then determined whether or not the performance of the unrecorded music selected and received as described above has ended (step S11). ). If it is determined that the performance of the song is not completed, the user switches the connection to the head unit during reception of the broadcast, for example, by changing the selection of the audio device from radio to CD or the like. It is determined whether or not the user has indicated an intention to end the reception of the broadcast by performing an operation such as turning off the power (step S14).

If such an operation is not performed, the process returns to step S11 to continue receiving. If it is determined in step S11 that the performance of the unrecorded music has ended, it is determined whether or not the reception of the broadcast is to be ended (step S12). If not, the process returns to step S6 and the next broadcast is performed. The above operation is repeated from acquisition of music information. Steps S12 and S1
When it is determined in step S4 that the reception has ended, the reception of the broadcast is ended and the above operation is ended (step S1).
5).

In the above-described embodiment, an example has been described in which when the same tune as the tune of the detected channel exists in the recorded tune information memory, the next channel is selected and received. It is also possible to sequentially select and check the channels broadcasting songs of the same genre. At this time, if the genre is also recorded in the recorded song information memory, the genre that is recorded most often is estimated as the genre that the user prefers, and the genre may be sequentially selected for the channel that is broadcasting. it can.

Although the above embodiment shows the basic operation of the present invention, the present invention can be implemented in various modes, for example, according to the operation flow shown in FIG. In the embodiment shown in FIG. 3, the same operation is performed up to step 7 in the operation flow of FIG.
The subsequent operations are performed from step S21 in FIG. 3 as illustrated. That is, for example, after the fetching of the recorded music information data of the audio recording medium as shown in FIG. 4A and the recording to the memory are performed before step S7 in FIG. 2, the user selects the up / down channel. It is determined whether or not the operation has been performed. If the operation has not been performed, the process proceeds to step S27, and the reception of the currently detected channel is continued without changing the channel for which the current reception setting is made ( Step S28). When the operation is performed, it is determined whether or not the same tune as the tune of the detection channel exists in the recorded tune information memory, similarly to step S8 of the operation flow of FIG. 2 (step S22). In this embodiment, an example in which the operation of the up / down key is detected is shown. However, the same operation can be performed by detecting the operation of the normal tuning key.

That is, in this embodiment, when a music selection operation is performed by an up / down key instead of a key switch for directly designating a receiving station, the user selects some music other than the music currently being received. The channel selection processing according to the present invention is performed assuming that the user desires to receive the signal. On the other hand, the channel selection processing according to the present invention is not performed at other times, and the same operation as the normal reception is performed. I'm trying to do it. When the up / down music selection operation is performed, the following operation may be performed after the next channel is actually selected in the channel selection unit 7 in FIG. 1, but this key switch operation is merely performed by the user's channel. Regarding the intention of the change, the actual change of the channel may be selectively performed by the following processing.

Next, when it is determined in step S22 that the same tune as the tune of the detected channel exists in the recorded tune information memory, in this embodiment, it is determined whether there are n or more artists recorded in the recorded tune information memory. Is determined (step S23).

Here, the tune of the same artist is, for example, 3
When it is determined that there are n or more songs as in the case of the songs or more, the user judges that the artist likes the songs of the artist, and checks whether or not there is a channel broadcasting the songs of the artist ( Step S24). This operation can be easily performed by the broadcast music information search unit 38 in FIG. 1 searching the broadcast music information memory 37 for each channel to see whether the artist exists. FIG. 4
In the example shown in FIG. 2, three songs by Hikaru Utada are recorded as shown in FIG. 2A, and the user judges that he likes the songs by Hikaru Utada. Search for channels that are broadcasting Utada Hikaru's songs among the currently broadcast channels. Result 3
It is searched that the song of Utada Hikaru is currently being broadcast on channel 4 and channel 4.

When it is determined in step S24 that there is a channel broadcasting the song of the artist, the channel is selected. At this time, as shown in the example shown in FIG. If there are a plurality of channels, a channel which broadcasts a song not recorded among the plurality of channels is selected (step S25). As a result, in the example of FIG. 4, Hikaru Utada's "Time Limit" broadcast on three channels is a recorded song, and "Hayatochiri" on four channels is a song not recorded, so four channels are selected. Is done.

On the other hand, when it is determined in step S23 that there is no artist who has recorded n or more songs in the recorded song information memory, that is, the user's favorite artist could not be determined from the recorded songs. Sometimes
One of the channels broadcasting a song that does not exist in the recorded song memory is selected (step S26). Also, in step S24, if there is an artist that has recorded n or more songs, but there is no channel broadcasting that artist's songs, similarly, any song that does not exist in the recorded song memory is broadcast. That channel is selected (step S26).

The channel selected in steps S25, S26 and S27 is subjected to the reception operation in step S28, and the selected music is played. Thereafter, it is determined whether or not the performance of the receiving station has been completed (step S29). If it has not been completed, it is determined whether or not the user has performed an up / down music selection operation. S2
Returning to step 9, the same operation is repeated. When the user performs an up / down song selection operation, the user determines that he / she wants to listen to a song different from the current song, selects the next channel, returns to step S22, and executes the same flow as described above. repeat. If it is determined in step S29 that the performance of the receiving station has been completed, the process returns to step S6 in FIG.

As described above, the function of the present invention for always receiving a song not recorded on the package medium when receiving an audio broadcast need not always be operated in the audio broadcast receiver. It is provided as one function of the audio broadcast receiver, and this function is used by the user's arbitrary selection, such as when performing the above-described up / down channel selection operation, or when separately performing a setting operation using this function. You can also

In the above embodiment, the digital audio broadcasting receiver is a digital broadcasting receiver for wireless communication such as satellite broadcasting or terrestrial digital broadcasting. It can be applied to the broadcasting of various types of audio data over the Internet using, for example, and the present invention is not limited to the digital broadcasting as described above. If possible, the present invention can be applied to various other audio broadcasts.

If the audio recording medium is, for example, MP3
For example, in the case of a CD-R in which about one hundred and several tunes have been recorded, it is almost certain that the recording covers almost all the songs of a particular artist. When the audio device detects that a digital broadcast receiver has broadcast a song that has not yet been recorded by the artist, it indicates that a new song is being broadcast and indicates this to the user. If the audio player has an audio data recording function, the data can be recorded and recorded as a new song.

Since the audio apparatus according to the present invention is configured as described above, in an audio apparatus in which an audio broadcast receiver and an audio player for reproducing an audio recording medium are connected, the music received by the audio broadcast receiver is an audio apparatus. The channel can be automatically changed when the song is recorded on a recording medium, and when the song broadcast on the changed channel is also a song recorded on an audio recording medium, the channel is changed to another channel. Since the audio broadcast can be changed, it is possible to always receive a song that is not recorded on the package medium in the audio broadcast, and the audio broadcast can be effectively utilized.

In another audio apparatus according to the present invention, the recorded music search section detects that the received music is recorded in the recorded music information memory, and the music of the same artist is stored in the recorded music information memory. It is recorded more than a predetermined number,
When there is a channel broadcasting the song of the artist, the reception channel changing means selects the channel, so that the audio device can know the artist of the user's favorite and Can be received with priority, and an audio device that is easy for the user to use can be provided.

Further, another audio device according to the present invention is characterized in that when a user operates a tuning key of the receiver,
Since the receiving channel is changed by the receiving channel changing means, the user is not broadcasting the song currently being broadcasted, but is an operation of indicating that the user wants to listen to another song. By detecting the operation of the key, the function of the present invention can be performed, and appropriate music selection corresponding to the user's will can be performed.

In another audio apparatus according to the present invention, there is provided a broadcast music information memory for each channel for recording information of music broadcast on a plurality of channels of audio broadcasting, and a specific music is stored in the broadcast music information for each channel. A broadcast music information search unit for searching whether or not the received music is recorded in the memory, and when the recorded music search unit detects that the received music is recorded in the recorded music memory, the broadcast music information search is performed. Searching for a channel that is broadcasting a song that is not recorded in the recorded song memory from the broadcast song information memory for each channel, and the receiving channel changing means selects the channel.
