FIG. 8 shows the music streaming playback terminal 2
3 is a flowchart showing the overall processing of terminal-side program processing at 0 and server-side program processing at the music streaming distribution server 10.

First, in the music streaming reproduction terminal 20, when the music streaming distribution server 10 accesses a music distribution homepage established on the communication network N (step A1), the distribution server 10 side stores the database 12a in the memory 12 thereof. The music data list stored in the music number / music name list memory 12a1 is read and transmitted to the music streaming reproduction terminal 20 that has accessed the music distribution homepage (step B1).

Then, on the reproduction terminal 20 side, a list of music data in which the music titles are associated with the music numbers received from the distribution server 10 is displayed on the liquid crystal display (LCD) 30 (step A2).

On the song data list display screen, when the song to be listened to is designated by operating the key input unit (key) 27 and stored in the designated song memory 28a1 in the RAM 28 (step A3), the distribution server 10 side The song number of the song designated by the user is received and stored in the designated song number memory 12b1 in the memory 12b (step B2).

The reproduction terminal 20 determines whether or not the reproduction terminal 20 has an image display function according to the image display enable / disable data 22b stored in the ROM 22 (step A4). If it is determined that there is a desired item, a desired item selection message to be reproduced in synchronization with the specified song, "What is the desired item? B
A lyrics explanation image for selecting data while listening to music "is displayed (step A5).

On the other hand, if it is determined that the user does not have the image display function, a desired item selection message to be reproduced in synchronization with the designated song "What is the desired item? A Lyrics explanation for selecting data while listening to music" Is displayed (step A6).

A desired item to be reproduced in synchronism with the designated tune selected and displayed according to whether or not it has the image display function is a key input unit (key) 2.
7, when the user designates and stores the designated item in the designated item memory 28a2 in the RAM 28 (step A7), the designated item is received by the distribution server 10 and stored in the designated item memory 12b2 (step A7). B3).

The reproduction terminal 2 having no image display function
At 0, when “a select data while listening to music” is specified, all items of “lyrics” and “commentary” are specified and transmitted to the distribution server 10. Similarly,
In the playback terminal 20 having the image display function, when “select data while listening to music b” is designated,
All items of “lyrics”, “explanation”, and “image” are designated and transmitted to the distribution server 10.

Thereafter, the music streaming distribution server 10 transmits data to the music streaming playback terminal 20 based on the user-specified music number and item stored in the specified music number memory 12b1 and the specified item memory 12b2. The process is shifted to the process (see FIG. 9) (step BC).

In connection with this, the music streaming playback terminal 20 performs data reception / streaming playback processing on music data of a specified song and data for each item which are transmitted and downloaded from the distribution server 10. (See FIG. 9) (Step AD).

FIG. 9 is a flowchart of the first embodiment showing the data transmission processing in the music streaming distribution server 10 and the data reception / streaming reproduction processing in the music streaming reproduction terminal 20 in association with each other.

First, the music streaming distribution server 10
In accordance with the user-specified song number and item stored in the designated song number memory 12b1 and the designated item memory 12b2, the header information (see FIG. 3) of the music data and item data is stored in the music data by song number. Memory 12a2
And read out from each item data memory 12a3 to 12a5 for each song number and transmitted to the music streaming playback terminal 20 (step C1). Further, the music data following each header information and the data body of each item are also read out, Sent to music streaming playback terminal 20 (step C
2).

The music streaming reproduction terminal 20 receives the user-specified music data and the header information of each item data transmitted from the distribution server 10 side, and stores the corresponding data memories 28b1, 28b2, 28b2, 28b2 in the FIFO memory 28b. 28b3,... (Step D1), based on this header information, the frame playback timing of each data "music data: 23.22 msec /
Lyrics data: 125 msec / explanation data: 125 msec / image data: 23.22 msec ”(step D2), and the user-specified music and data of each item transmitted from the distribution server 10 are multi-channel data. Are sequentially received (step D3) and the FIFO memory 2
8b, corresponding data memories 28b1, 28b2, 28
b3,... (step D4).

Here, the music data and each item data received and stored in the reception music data memory 28b1 in the FIFO memory 28b and the reception designation data memories 28b2, 28b3,. It is determined whether or not the data amount (for example, 5 seconds) has been stored (step D5). If it is determined that there is data for which the data amount for the certain reproduction time has not been received and stored, the data amount is insufficient. Is transmitted to the music streaming distribution server 10 (step D5 → D6).

Then, on the distribution server 10 side, it is determined whether or not a transmission instruction for the missing data has been received (step C3). If it is determined that the transmission instruction for the missing data has been received, the user-specified Only the music data of the music and the data designated to be insufficient among the specified item data are read out preferentially and transmitted to the music streaming reproduction terminal 20 (steps C3 → C4).

On the other hand, in a state where the transmission instruction of the insufficient data is not received, the transmission processing in the step C2 is continued, and the music streaming reproduction terminal 20 of the music data designated by the user and the data body of each item is further transmitted. Is transmitted using multi-channel data (step C).
3 → C5).

In the music streaming playback terminal 20, when data that is insufficient for the predetermined playback time is preferentially received (step D7), the received data corresponds to the corresponding data in the FIFO memory 28b in the same manner as described above. Are stored in the reception data memories (28b1, 28b2, 28b3,...) (Step D8), and are again received and stored in the reception music data memory 28b1 and the reception designation data memories 28b2, 28b3,. It is determined whether or not the data amount for a certain reproduction time is stored for each of the music data and each item data (step D5).

The music data and item data received and stored in the reception music data memory 28b1 and the reception designation data memories 28b2, 28b3,. When it is determined that the data amount has been stored, first, the playback time of the next frame of the music data managed by the music playback time memory 28a5 is reset (step D5 → D9), and the playback time of each designated item is also reset. The reproduction time of the next frame for each designated item data managed in the memory 28a6 is reset (step D1).
0).

Then, the reference reproduction time count in the time counter memory 28a4 is started (step D11), and the user-specified music data and the data of each item transmitted as multi-channel data from the distribution server 10 are received. (Step D1
2) and while the storage processing (step D13) in the corresponding reception data memories (28b1, 28b2, 28b3,...) In the FIFO memory 28b is continued, the reference counted by the time counter memory 28a4 is maintained. First, it is determined whether or not the playback time has reached the playback time of the next frame of the music data managed by the music playback time memory 28a5 (step D14).

In this case, since the reproduction time of the next frame of the music data managed by the music reproduction time memory 28a5 is reset to "0" at the initial stage of the reproduction of the distribution data, the reference time in the time counter memory 28a4 is reset. It is determined that the next reproduction time of the music data has arrived at the start of the counting of the reproduction time, and the music data of one frame is taken out from the head of the received music data memory 28b1 in the FIFO memory 28b, and the digital signal processor (DSP) 31 , D / A converter (DAC) 3
2 through the speaker 33 (step D
14 → D15).

Then, the music reproduction time memory 28a5
The playback time of the next frame of the music data managed by is updated according to the frame playback timing "music data: 23.22 msec" based on the header information (step D16).

Then, the designated item memory 2 in the RAM 28
In step 8a2, if it is determined that the item a or b, "select data while listening to music" is specified and stored (step D17), the current item of the music being reproduced in the specified item memory 28a3 is determined. It is determined whether or not the item specified in (1) is stored (step D1).
8).

If it is determined that there is a designated item during music playback, the data of the designated item is set as data of an item to be displayed in synchronization with the current music playback (step D19). That is, during the music reproduction, for example, when an item of lyrics is designated, the lyrics data stored in the reception designation data memory 28b2 is set as data to be displayed in synchronization with the music data currently being reproduced. .

On the other hand, the designated item memory 28 in the RAM 28
In a2, when it is determined that the item a or b, "select data while listening to music" is specified and stored (step D17), the music being reproduced in the specified item memory 28a3 is determined. If it is determined that there is no designated item (step D18), the data of the previously designated item is set as the data of the item to be displayed in synchronization with the music reproduction (step D20). In other words, during the music playback, if, for example, a commentary item is designated as the previous designated item, the commentary data stored in the reception designation data memory 28b3 is synchronized with the music data currently being reproduced. It is set as it is as data to be displayed.

On the other hand, the designated item memory 28 in the RAM 28
In a2, instead of the item a or b, "select data while listening to music" is designated and stored, the individual item "lyric description image" is selectively designated and stored. In this case, the specified item is set as data to be displayed in synchronization with the music data being reproduced (step D17 "No").

For the data of the designated item to be displayed in synchronization with the music data currently being reproduced, which is set in accordance with the processing of steps D17 to D20, the reference reproduction time counted in the time counter memory 28a4. It is determined whether or not has reached the playback time of the next frame of the data of the designated item managed by each designated item playback time memory 28a6 (step D21).

In this case, at the beginning of the reproduction of the distribution data, the reproduction time of the next frame of the data of the designated item to be displayed in synchronization with the music data managed by the designated item reproduction time memory 28a6 is reset to "0". Therefore, it is determined that the next reproduction time of the data of the designated item has arrived at the same time as the start of the reference reproduction time in the time counter memory 28a4, and the process proceeds to the synchronous reproduction processing of the designated data (see FIG. 10), and the FIFO memory , The first frame of the designated item data is taken out from the designated reception data memories 28b2, 28b3,... And synchronously reproduced and displayed on the liquid crystal display (LCD) 30 (step D).
E).

That is, if the data of the designated item to be displayed in synchronization with the currently reproduced music data set in accordance with the processing of steps D17 to D20 is, for example, lyrics data, the reception designated data memory 28b2 The first one frame of the lyrics data stored in the memory is taken out and displayed synchronously. If the data is commentary data, the first frame of the commentary data stored in the reception designation data memory 28b3 is retrieved. Displayed synchronously.

The playback time of the next frame of the data of the designated item to be displayed in synchronization with the music data managed in the designated item playback time memory 28a6 is determined by the frame playback timing “lyric data: 12” based on the header information.
5msec / Explanation data: 125msec / Image data: 23.22mse
c "(step D22).

Then, it is determined whether or not the retrieval and reproduction of the music data sequentially received and stored in the reception music data memory 28b1 in the FIFO memory 28b has been completed (step D23), and it is determined that the reproduction has not been completed. Then, the processing of steps D12 to D22 is repeated,
Streaming reproduction of specified item data synchronized with streaming reproduction of the music data while sequentially storing user-specified music data and data of each specified item transmitted from the distribution server 10 as multi-channel data in the FIFO memory 28b. Display is performed.

On the other hand, the music streaming distribution server 10
On the side, the transmission by the multi-channel data is repeated until the music data specified by the user and the data of each specified item are completed (steps C6 → C3 to C3).
5).

Then, the data transmission from the music streaming distribution server 10 is completed, and the music streaming reproducing terminal 20 finishes extracting and reproducing the music data sequentially received and stored in the received music data memory 28b1 in the FIFO memory 28b. When it is determined that the process has been completed, the series of data reception / streaming reproduction processing is terminated and returned (step D23 → return), and the state returns to the homepage access state for designating the next song desired by the user.

FIG. 10 is a flowchart showing the synchronous reproduction process of the designated data accompanying the data reception / streaming reproduction process of the music streaming reproduction terminal 20.

That is, for the data of the specified item to be displayed in synchronization with the music data currently being reproduced, the reference reproduction time counted by the time counter memory 28a4 is managed by the specified item reproduction time memory 28a6. When it is determined that the reproduction time of the next frame of the data of the specified item has arrived, the process proceeds to the synchronous reproduction process of the specified data. First, the reception specified data memories 28b2, 28b3,. , The first frame of the designated item data (character data or image data of lyrics or commentary) is extracted (step E).
1).

Then, the contents of the control code added to the designated item data for one frame are determined, and it is determined whether the control code is a scroll instruction control code (step E2) or a stop instruction control code (step E3). It is determined whether or not the control code is a control code for controlling the external device (step E4).

Here, when a meaningful control code is not added to the designated item data, the designated item data for one frame is rewritten and displayed as the screen data of the liquid crystal display (LCD) 30 as it is. (Step E4 → E5).

When the content of the control code added to the designated item data is determined to be a control code for a scroll instruction, the screen data of the liquid crystal display (LCD) 30 is scrolled in the designated direction. Accordingly, the designated item data for the one frame is added and scroll-displayed (steps E2 → E6).

When the content of the control code added to the designated item data is determined to be the control code for the stop instruction, the screen data of the liquid crystal display (LCD) 30 is changed to the one-frame designated item data. Is stopped and reproduced for the reproduction time interval (step E3 → E7).

That is, for example, the lyrics data can be scroll-displayed one character at a time in synchronization with the music data being reproduced, or can be displayed intermittently.
Further, for example, image data such as a promotion video can be scroll-displayed one frame image at a time in synchronization with music data being reproduced, or can be displayed intermittently sequentially.

Further, when the content of the control code added to the designated item data is determined to be a control code for controlling the external device, the control signal obtained in synchronization with the music reproduction is output to the external device control signal output section. The signal is output from the terminal 34 and transmitted to the game machine 36 or the like (steps E4 → E8), for example, a dance step instruction display synchronized with music reproduction is performed.

FIG. 11 is a diagram showing a control display state when the designated item to be synchronized with music data in the music streaming reproduction terminal 20 is image data.

That is, the image amount per frame of the image data is set to 1 / n of one screen data, and successive 1 / n images are sequentially transmitted at predetermined frame intervals with a scroll control code added. By setting the control code of "wait" for a plurality of frames during that time, an image display that scrolls intermittently in synchronization with music playback is performed.

Therefore, the music streaming distribution server 10 and the music streaming reproduction terminal 20 having the above-described configurations
According to the music streaming distribution and playback function in
The reproduction terminal 20 accesses the distribution server 10 to specify a desired song from a list of song names (12a1) stored in the database 12a of the distribution server 10, and
When items such as lyrics / comment / image to be displayed in synchronization with the song are designated, the distribution server 10 stores the music data (12a2) corresponding to the designated song number and the data of the designated item in the header information. , A time interval for synchronous reproduction is written and transmitted to the reproduction terminal 20. Then, in the playback terminal 20, the received music data of the designated song and the data of the designated item are stored in the corresponding FIFO memory 28b, and the music data is reproduced from the beginning at the playback timing based on the header information. In synchronization with the sequential streaming playback, the data of the specified item is also sequentially streamed and displayed at the playback timing based on the header information, so that the designated item data is arbitrarily designated in synchronization with the desired music data playback. Character data such as lyrics / comments and image data such as promotion videos can be displayed.

Further, according to the music streaming distribution server 10 and the music streaming distribution / reproduction function of the music streaming reproduction terminal 20 having the above-described configuration, a desired music is designated on the reproduction terminal 20 and synchronized with the music. When the lyrics / description / image to be displayed is specified as the item of “select while listening to music”, the distribution server 10 transmits the music data of the specified song and the data of each item to the reproduction terminal 20. Then, in the reproduction terminal 20, when an arbitrary item is selected and specified during the reproduction of the received music data of the specified song, only the data of the specified item is selectively taken out from the FIFO memory 28b and Since the information is displayed in synchronization with the music reproduction, it is possible to synchronously reproduce and display the desired item in the lyrics / description / image while switching the music.

Further, according to the music streaming distribution / reproduction function of the music streaming distribution server 10 and the music streaming reproduction terminal 20 having the above-described configuration, the distribution server 10 transmits the music data to the reproduction terminal 20 together with the music data designated by the user. The data of the specified items such as lyrics / description / image to be synchronized with the data is transmitted with a control code such as display stop or scroll display added. Can be controlled.

In the process (see FIG. 9) between the data transmission process in the music streaming distribution server 10 and the data reception / streaming reproduction process in the music streaming reproduction terminal 20 according to the above-described embodiment (see FIG. 9), the distribution server 10 On the other hand, the case where the music data of the music designated by the user and the data of the designated item are transmitted as multi-channel data for streaming reproduction has been described, but as shown in FIG. For each delivery frame, the data of each designated item to be synchronized with each other may be sequentially arranged in a time-division multiplexed manner with respect to each item data of the synchronization frame, and transmitted to the playback terminal 20 for streaming playback.

FIG. 12 is a flowchart of the second embodiment showing the data transmission processing in the music streaming distribution server 10 and the data reception / streaming reproduction processing in the music streaming reproduction terminal 20 in association with each other.

First, the music streaming distribution server 10
In accordance with the user-specified song number and item stored in the designated song number memory 12b1 and the designated item memory 12b2, the header information (see FIG. 3) of the music data and item data is stored in the music data by song number. Memory 122
The music data is read from the item data memories 12a3 to 12a5 for each music number and transmitted to the music streaming reproduction terminal 20 (step C1).

Then, the music streaming playback terminal 20
, The user-specified music data and the header information of each item data transmitted from the distribution server 10 are received and stored in the corresponding data memories 28b1, 28b2, 28b3,... In the FIFO memory 28b ( Step D1) Based on this header information, the frame reproduction timing of each data “music data: 23.22 m
sec / Lyrics data: 125 msec / Explanation data: 125 msec / Image data: 23.22 msec ”(step D)
2).

Further, the music streaming distribution server 1
At 0, the time count is started (step C
2) Accompanying this, first, music data specified by the user is extracted from the database 12a for one frame (see FIG. 3) and set as time-division composite data (see FIG. 4) (step C3).

Then, the data of each item specified by the user is synchronized with the one-frame music data set in the time-division composite data according to the frame reproduction timing described as the header information. It is determined whether it is the timing (step C
4) For the data of the item that is the synchronous playback timing, one frame is taken out of the database 12a and set in the simultaneous division composite data (step C).
4 → C5).

Then, one frame of time-division composite data, which is set in advance by combining data frames of items to be synchronized with one frame of designated music data, is transmitted to the reproduction terminal 20 (step C6). .

When the music streaming reproduction terminal 20 receives the one-frame time-division composite data transmitted from the distribution server 10 (step D3),
Each data included in the time-sharing composite data is the same as the FI
Each corresponding data memory 28b1 in the FO memory 28b,
28b2, 28b3,... (Step D
4) It is determined whether data for a certain reproduction time has been stored (step D5).

If it is determined that the FIFO memory 28b does not store music data for a certain reproduction time and item data to be synchronized with the music data,
The processing after the step D3 is repeated, the next frame of the time-division composite data sequentially transmitted in the distribution server 10 is received, and the FIFO memory 28b
, The corresponding data memories 28b1, 28b2, 28b3,
(Step D5 → D3)
D4).

If it is determined in the FIFO memory 28b that the music data for a certain reproduction time and the item data to be synchronized with the music data are stored, first the music data managed by the music reproduction time memory 28a5 The reproduction time of the next frame of the data is reset (step D5 → D6), and the reproduction time of the next frame for each specified item data managed by each specified item reproduction time memory 28a6 is reset (step D7). .

Then, the reference reproduction time count in the time counter memory 28a4 is started (step D8), and the user-specified music data and data of each item transmitted from the distribution server 10 as time-division composite data are received. While the processing (step D9) and the storage processing (step D10) in the corresponding reception data memories (28b1, 28b2, 28b3,...) In the FIFO memory 28b are continued, the time counter memory 28a4 counts. First, it is determined whether or not the reference reproduction time has reached the reproduction time of the next frame of the music data managed by the music reproduction time memory 28a5 (step D11).

In this case, since the reproduction time of the next frame of the music data managed by the music reproduction time memory 28a5 is reset to "0" at the beginning of the reproduction of the distribution data, the reference time in the time counter memory 28a4 is reset. It is determined that the next reproduction time of the music data has arrived at the start of the reproduction time counting, and one frame of music data is extracted from the head of the reception music data memory 28b1 in the FIFO memory 28a, and the digital signal processor (DSP) 31 , D / A converter (DAC) 3

11 → D12).

The music reproduction time memory 28a5
The reproduction time of the next frame of the music data managed by is updated according to the frame reproduction timing "music data: 23.22 msec" based on the header information (step D13).

Then, the designated item memory 2 in the RAM 28
In step 8a2, when it is determined that the item a or b, "select data while listening to music" is designated and stored (step D14), the current item of the music being reproduced in the designated item memory 28a3 is determined. It is determined whether or not the item specified in (1) is stored (step D1).
5).

When it is determined that there is a designated item during music playback, the data of the designated item is set as data of an item to be displayed in synchronization with the current music playback (step D16). That is, during the music reproduction, for example, when an item of lyrics is designated, the lyrics data stored in the reception designation data memory 28b2 is set as data to be displayed in synchronization with the music data currently being reproduced. .

On the other hand, the designated item memory 28 in the RAM 28
In a2, when it is determined that the item a or b, "select data while listening to music" is designated and stored (step D14), the music being played back in the designated item memory 28a3 is determined. If it is determined that there is no designated item (step D15), the data of the previously designated item is set as the data of the item to be displayed in synchronization with the music reproduction (step D17). In other words, during the music playback, if, for example, a commentary item is designated as the previous designated item, the commentary data stored in the reception designation data memory 28b3 is synchronized with the music data currently being reproduced. It is set as it is as data to be displayed.

On the other hand, the designated item memory 28 in the RAM 28
In a2, instead of the item a or b, "select data while listening to music" is designated and stored, the individual item "lyric description image" is selectively designated and stored. In this case, the designated item is set as data to be displayed in synchronization with the music data being reproduced (step D14 "No").

The data of the designated item to be displayed in synchronization with the music data currently being reproduced, which is set in accordance with the processing of steps D14 to D17, is the reference reproduction time counted by the time counter memory 28a4. It is determined whether or not has reached the playback time of the next frame of the data of the specified item managed by each specified item playback time memory 28a6 (step D18).

In this case, at the initial stage of the reproduction of the distribution data, the reproduction time of the next frame of the data of the designated item to be displayed in synchronization with the music data managed by the designated item reproduction time memory 28a6 is reset to "0". Therefore, it is determined that the next reproduction time of the data of the designated item has arrived at the same time as the start of the reference reproduction time in the time counter memory 28a4, and the process proceeds to the synchronous reproduction processing of the designated data (see FIG. 10), and the FIFO memory .. From the reception designation data memory 28b2, 28b3,..., And are synchronously reproduced and displayed on the liquid crystal display (LCD) 30 (step D).
E).

That is, when the data of the designated item to be displayed in synchronization with the music data currently being reproduced, which is set in accordance with the processing of steps D14 to D17, is, for example, lyrics data, the reception designated data memory 28b2 The first one frame of the lyrics data stored in the memory is taken out and displayed synchronously. If the data is commentary data, the first frame of the commentary data stored in the reception designation data memory 28b3 is retrieved. Displayed synchronously.

The playback time of the next frame of the data of the designated item to be displayed in synchronization with the music data managed in the designated item playback time memory 28a6 is determined by the frame playback timing "lyric data: 12" based on the header information.
5msec / Explanation data: 125msec / Image data: 23.22mse
c) (step D19).

Then, it is determined whether or not the retrieval and reproduction of the music data sequentially received and stored in the received music data memory 28b1 in the FIFO memory 28b has been completed (step D20), and it is determined that it has not been completed. Then, the processes of steps D9 to D19 are repeated, and the user-specified music data and the combination data of each specified item transmitted from the distribution server 10 as time-division composite data are sequentially stored in the FIFO memory 28b. The streaming playback display of the designated item data synchronized with the streaming playback of the music data is performed.

On the other hand, the music streaming distribution server 10
On the side, the transmission by the time-division composite data is repeated until the data of the music data designated by the user and the data of each designated item to be synchronized therewith are completed (steps C7 → C3 to C6).

Then, the data transmission from the music streaming distribution server 10 has been completed, and the music streaming reproduction terminal 20 has finished extracting and reproducing the music data received and stored in the received music data memory 28b1 in the FIFO memory 28b. Is determined, the series of data reception / streaming reproduction processing is terminated and returned (step D20 → return), and the state returns to the homepage access state for designating the next song desired by the user.

Therefore, the music streaming distribution server 10 and the music streaming playback terminal 20 having the above-described configurations are provided.
