The printing unit 80 performs printing under the control of the control unit 10.
[0033]
  FIG. 3 is a functional block diagram showing the configuration of the Internet server 6. In general, a WWW server that enables browsing of Web pages and a streaming server that distributes streaming data are individually constructed, but in this embodiment, these server functions are one Internet server 6. It is assumed that they are provided together. The Internet server 6 is physically a personal computer except that a large-capacity hard disk for storing streaming data having a relatively large amount of data and a mechanism for efficiently distributing data are provided. It is not different from the main body configuration.
[0034]
  The Internet server 6 includes a request receiving unit 600, a URL switch 610, a Web page URL table 620, a streaming data URL table 630, a related information specifying URL table 640, a Web page storage unit 650, a streaming data storage unit 660, and a related information storage unit 670. And a data transmission unit 680 and the like.
[0035]
  The request reception unit 600 receives a request to transmit a Web page, streaming data, and related information together with their URLs, and transfers the received information to the URL switch 610. The URL switch 610 distributes requests to the tables 620 to 640 based on the URL from the request reception unit 600. The Web page URL table 620 represents the correspondence between the Web page URL and the Web page storage location in the Web page storage unit 650, and is referred to when specifying the Web page corresponding to the request. The streaming data URL table 630 represents the correspondence between the streaming data URL and the streaming data storage location in the streaming data storage unit 660, and is referred to when specifying the streaming data corresponding to the request. The related information specifying URL table 640 represents a correspondence relationship between a later-described time stamp or related information specifying URL and a storage location of the related information in the related information storage unit 670, and specifies related information corresponding to the request. To be referenced. The web page storage unit 650 stores various web pages in HTML (Hypertext Markup Language) format, for example. The streaming data storage unit 660 stores various streaming data as audio data and movie data. The related information storage unit 670 stores related information related to a point in time during playback of streaming data. The data transmission unit 680 transmits the data called from the storage units 650 to 670 in response to the request to the personal computer 1 that is the request source.
[0036]
  Next, the main points will be described.
[0037]
  For example, on the personal computer 1, by receiving streaming data from the Internet server 6, a plurality of songs are being played back in sequence, and for the song currently playing at the time of the playback, related information regarding the lyrics of the song is requested. When a key input or a click operation for printing out is performed, a time stamp indicating a reproduction time at the time of the operation is included in a request for related information and sent to the Internet server 6.
[0038]
  In the Internet server 6, related information that represents the lyrics of the song that was being reproduced at the time of the operation based on the time stamp is specified in a text base, and this related information is sent to the personal computer 1.
[0039]
  On the personal computer 1 side, printing is performed by the printer 2 based on the received related information, and the lyrics of the song being played at the time of operation are obtained as a printing result. As a result, if the streaming data is simply played back, the music and video based on the streaming data are merely viewed. However, according to the present embodiment, related information related to the point in time during playback can be separately acquired. It is.
[0040]
  Next, basic operations will be described in detail with reference to flowcharts.
[0041]
  FIG. 4 is a flowchart showing a streaming data reception / playback processing procedure in the personal computer 1. On the personal computer 1, it is assumed that a Web page is displayed on the display unit 70 and immediately after the streaming content link arranged in the Web page is specified by the user.
[0042]
  When a link for streaming content is designated by the user, the control unit 10 of the personal computer 1 requests the Internet server 6 to transfer a metafile. In response to this, when receiving the metafile sent from the Internet server 6, the control unit 10 transmits this metafile to the playback player task 13. The meta file includes the URL of streaming data. In the playback player task 13, a request for starting transmission of streaming data is transmitted to the Internet server 6 based on the streaming data URL included in the metafile by the request transmission task 130 (S1).
[0043]
  When the streaming data sent from the Internet server 6 is received accordingly (S2: YES), the control unit 10 sets the playing flag to “1” (S3), and further starts counting the playing time. (S4) The reproduction processing of the received streaming data is started (S5). According to this streaming data reproduction process, while the received streaming data is stored in the streaming buffer area 24 to some extent, the data is simultaneously reproduced while being read / written at high speed by the FIFO method. Incidentally, the in-reproduction flag is status information indicating the reproduction state of the streaming data, and is held at “0” before reproduction.
[0044]
  When the user performs a key input or a click operation for acquiring related information during reproduction of such streaming data (S6: YES), the control unit 10 executes a subroutine as an interrupt process and starts reproduction. A time stamp indicating an elapsed time (reproduction time) until the operation time is acquired (S21), and a request to start transmission of related information at the operation time including this time stamp is transmitted to the Internet server 6. (S22). Note that streaming data is being played back even during execution of the subroutine.
[0045]
  Thereafter, the control unit 10 sets the print flag to “1” (S23), and monitors the reception status of the related information specifying URL sent from the Internet server 6 in response to the request (S24). Incidentally, the print flag is status information indicating the print status of the related information, and is held at “0” before printing.
[0046]
  When the related information specifying URL is received from the Internet server 6 (S24: YES), the control unit 10 transmits the received related information specifying URL to the Internet server 6 (S25). When the related information specifying URL cannot be received from the Internet server 6 (S24: NO), the control unit 10 monitors the reception status of the related information specifying URL until the specified time elapses. If the message cannot be received, a message to that effect is displayed on the display unit 70, and the process proceeds to S6: NO.
[0047]
  When the related information corresponding to the transmitted related information specifying URL is received from the Internet server 6 (S26: YES), the control unit 10 causes the printer 2 to print the received related information (S27). Thereby, even during reproduction while receiving streaming data, it is possible to acquire and print related information requested at a point in the middle from the Internet server 6. When the related information from the Internet server 6 cannot be received (S26: NO), the control unit 10 monitors the reception status of the related information until the specified time elapses, but cannot be received even after the specified time elapses. Displays a message to that effect on the display unit 70, and then proceeds to S6: NO or later.
[0048]
  Thereafter, when the reproduction of the streaming data is finished (S7: YES), the control unit 10 sets the reproducing flag to “0” (S8), and determines whether or not the print flag is set to “1”. (S9).
[0049]
  When the print flag is “1” (S9: YES), the control unit 10 further determines whether or not the related information printing process has already been completed (S10).
[0050]
  When the printing process is finished (S10: YES), the control unit 10 sets the print flag to “0” (S11), and finishes this streaming data reception / playback process.
[0051]
  If the printing process is being continued in S10 (S10: NO), the control unit 10 waits until the printing process is completed.
[0052]
  In S9, when the print flag is “0” (S9: YES), the control unit 10 ends the streaming data reception / reproduction processing as it is.
[0053]
  In S7, when the reproduction of the streaming data is not finished (S7: NO), the control unit 10 returns to S5 and continues the reproduction process of the streaming data.
[0054]
  In S6, when no key input or click operation for acquiring related information is performed during reproduction of streaming data (S6: NO), the control unit 10 proceeds to S7 as a normal main routine.
[0055]
  In S2, when the streaming data from the Internet server 6 cannot be received (S2: NO), the control unit 10 monitors the reception status of the streaming data until the specified time elapses. In such a case, a message to that effect is displayed on the display unit 70, and then the streaming data reception / reproduction process is terminated.
[0056]
  FIG. 5 is a flowchart showing a streaming data distribution processing procedure in the Internet server 6.
[0057]
  In the Internet server 6, when the request reception unit 600 receives a request for streaming data from the personal computer 1 (S31: YES), the streaming data URL table 630 is searched for the streaming data corresponding to the streaming data URL included in the request. To do. The streaming data obtained as a search result is read from the streaming data storage unit 660, and the data transmission unit 680 transmits the streaming data to the personal computer 1 (S32).
[0058]
  Thereafter, when a request for related information including a time stamp is received from the personal computer 1 being reproduced while receiving the streaming data (S33: YES), the related information specifying URL corresponding to the time stamp is related to the related information specifying URL table 640. (S34). The related information specifying URL obtained as a search result is transmitted to the personal computer 1 through the data transmission unit 680 as it is (S35).
[0059]
  When there is a reply from the personal computer 1 regarding the transmitted related information specifying URL (S36: YES), related information corresponding to the related information specifying URL is searched from the related information specifying URL table 640, and the related information obtained as a search result is obtained. Is transmitted to the personal computer 1 through the data transmission unit 680 (S37).
[0060]
  When the transmission of the related information is completed (S38: YES), it is determined whether or not there is a notification that all the streaming data has been received from the personal computer 1 (S39). S39: YES), this streaming data distribution processing is finished.
[0061]
  In S39, when there is no notification of reception completion (S39: NO), the process returns to S32 and transmission of streaming data is continued.
[0062]
  If the transmission of the related information is not completed in S38 (S38: NO), the process returns to S37 and the transmission of the related information is continued.
[0063]
  In S36, when there is no reply from the personal computer 1 about the transmitted related information specifying URL (S36: NO), the process proceeds to S39.
[0064]
  In S33, if there is no particular request for related information (S33: NO), the process proceeds to S39.
[0065]
  If there is no request for streaming data in S31 (S31: NO), the process waits until there is a request.
[0066]
  Therefore, according to the above-described embodiment, there is a point of interest or details in the middle of reproduction of streaming data on the personal computer 1, and at that time, key input or click operation for acquiring related information is performed. If it does, since the relevant information regarding the point in time can be acquired from the Internet server 6 and printed, only one streaming data can be used for multiple purposes, and the relevant information derived from the streaming data can be effectively used. Can do.
[0067]
  Further, a time stamp indicating the reproduction time at the operation time is included in the request for related information and transmitted from the personal computer 1 to the Internet server 6, and the reproduction contents at the operation time based on the time stamp are transmitted from the Internet server 6. Since the related information corresponding to is transmitted, it is possible to acquire the related information that matches the operation timing on the personal computer 1 on the reproduction side, and to prevent the inconvenience that related information that is not intended by the user is transmitted. be able to.
[0068]
  Furthermore, other embodiments will be described. Since the other embodiments are common in many respects to the above-described embodiment, these common points will be denoted by the same reference numerals and the like, will not be described and will be described with emphasis on different points.
[0069]
  FIG. 6 is a functional block diagram showing a configuration of an Internet server according to another embodiment.
[0070]
  According to the Internet server which concerns on other embodiment, the streaming data which made it possible to reproduce | regenerate a some song in order are delivered, and the related information for printing the lyrics of each song regarding the streaming data is also delivered. And after delivery of related information, karaoke data consisting only of karaoke songs is delivered as streaming data.
[0071]
  Therefore, in the streaming data storage unit 661, streaming data as song information including a singing voice is stored, and karaoke data only for accompaniment without a singing voice is also stored as streaming data. The streaming data URL table 631 describes the correspondence between streaming data URLs including karaoke data URLs and streaming data storage locations in the streaming data storage unit 661. Further, the related information specifying URL table 641 describes the storage location of the related information in the related information storage unit 670, and includes the time stamp and the related information specifying URL and the storage location of the karaoke data in the streaming data storage unit 661. The correspondence is also described.
[0072]
  FIG. 7 is a flowchart illustrating a streaming data reception / playback processing procedure according to another embodiment. In this flowchart, streaming data means data including a singing voice, and karaoke data means data not including a singing voice.
[0073]
  When S41 to S45 are executed in the same manner as S1 to S5 in FIG. 4 and a user performs a key input or click operation for acquiring related information during reproduction of streaming data (S46: YES), interrupt processing is performed. The subroutine is executed, and the control unit 10 ends the reproduction of the streaming data (S51), and sets the reproducing flag to “0” (S52). That is, according to the subroutine executed at this time, the reproduction of the streaming data is interrupted, and the execution of the main routine is controlled exclusively.
[0074]
  And the control part 10 performs S53-S55 similarly to S21-S23 of FIG. 4, but after that, the control part 10 receives related information specific URL and karaoke data URL sent according to a request. The situation is monitored (S56).
[0075]
  When the related information specifying URL and the karaoke data URL are received from the Internet server (S56: YES), the control unit 10 first transmits the received related information specifying URL to the Internet server (S57). When the related information specifying URL and the karaoke data URL cannot be received (S56: NO), the control unit 10 monitors the reception status of the related information specifying URL until the specified time elapses.
