Abstract

<P>PROBLEM TO BE SOLVED: To enable users to start a communication by being commonly interested in a subject at that time and to smoothly and surely communicate. <P>SOLUTION: When a user of a terminal 1a tries to communicate with another user while a wireless network is established between the terminal 1a and another terminal, provision of a music piece play history in each of other terminals (a play starting time for a piece of music being reproduced) is requested from the terminal 1a to the other terminals. Based on the music piece play histories, the user of the terminal 1a selects a piece of music desired from pieces of music being reproduced in the other terminals. If there are a plurality of other terminals reproducing the selected piece A of music, the terminal 1a selects a terminal 1b with a longest residual play time and plays the piece A of music from a position that the terminal 1b reproduces simultaneously with the terminal 1b. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a content reproduction method between a plurality of terminals that form a wireless network, and a wireless terminal that forms a wireless network with other terminals.

  With the spread of communication networks and communication terminals, there is a desire to communicate with many people and make many close friends. However, the reality is that there are few opportunities to start communication with others, and it is often difficult to start communication even if you want to communicate.

  As a method for assisting communication formation, Japanese Patent Application Laid-Open No. 2004-320658 discloses that multi-hop peer-to-peer communication is performed in a wireless network including a plurality of wireless terminals.

  In addition, a device is conceivable in which each user sets personal information or preference information in advance, finds other users who have the same interest based on the personal information or preference information, and realizes communication.

  Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2004-54023), each user has a list of music pieces recommended by each user, and the recommended music list is exchanged between the terminals. It is shown that a mobile music terminal of a certain user generates a collected music list in which recommended music lists of other users are collected, and selects music according to the number of users who recommend music.

The prior art documents listed above are as follows.
JP 2004-320658 A JP 2004-54023 A

  However, since a person's preferences change from moment to moment depending on conditions such as the place where the person is placed and the date and time, the method of registering preference information in advance as in the past has been registered. If the preference information becomes different from the preference at the time of searching for the person who actually communicates, there is a risk that communication will start based on content that is not of interest at all, and subsequent communication will be smooth The possibility of not progressing is increased.

  In view of this, the present invention allows users to start communication based on their common interests at the time, and to smoothly and reliably advance communication to form a community. .

The content reproduction method of the first invention is
A method for reproducing content between a plurality of terminals forming a wireless network,
A first step for requesting that one terminal transmit to the other terminal at least the content being played on the other terminal or the information of the playback history of the content designated by the one terminal on the other terminal; ,
A second step in which the other terminal transmits the reproduction history information to the one terminal in response to the request;
Based on the transmitted reproduction history information, the one terminal is reproducing the content selected by the one terminal and simultaneously reproduces the content on the other terminal having the longest remaining reproduction time. A third step of selecting as another terminal to perform,
A fourth step in which the one terminal plays the content from a position being played on the selected other terminal;
It is characterized by providing.

The content reproduction method of the second invention is
A method for reproducing content between a plurality of terminals forming a wireless network,
A first step for requesting that one terminal transmit to the other terminal at least the content being played on the other terminal or the information of the playback history of the content designated by the one terminal on the other terminal; ,
A second step in which the other terminal transmits the reproduction history information to the one terminal in response to the request;
Based on the transmitted reproduction history information, the one terminal is reproducing the content selected by the one terminal, and the remaining reproduction time is a predetermined time or a total of the remaining reproduction time. A third step of selecting another terminal whose ratio to the reproduction time is a predetermined ratio or more as another terminal for simultaneously reproducing the content;
A fourth step in which the one terminal plays the content simultaneously with the selected other terminal;
It is characterized by providing.

  In the content reproduction method according to the first or second invention, the content selected by one terminal is not only for the user of the one terminal, but also for other users who are actually reproducing the content on another terminal. It is of interest at that time, and is suitable as an opportunity for the user of one terminal to start communication with the user of the other terminal.

  Moreover, in the one terminal, the remaining reproduction time of the content is the same as the other terminal, the remaining reproduction time of the content is a predetermined time or more, or the ratio of the remaining reproduction time to the total reproduction time is a predetermined ratio. Since the content is played at the same time as the other terminals described above, it is sufficient as an opportunity to start communication, and communication can proceed smoothly and reliably.

  As described above, according to the present invention, it is possible to form a community by starting communication with the user having a common interest at that time, and proceeding with communication smoothly and reliably.

  The terminal 1 as described above is given a terminal ID (identifier) that uniquely identifies each terminal on the wireless network.

[2. Music playback method: FIGS. 3 to 11]
(2-1. Music playback history at each terminal)
The storage unit 22 of the terminal 1 (1a, 1b, 1c, 1d,...) Records the music reproduction history at each terminal.

  The user of the terminal 1a plays the same music at the same time from the terminals 1b, 1c, 1d and 1e that can communicate with the terminal 1a, starting at the time of 12:00 on December 14, 2004. 3A, 3B, 3C, 3D, and 3E are shown in FIGS. 3A, 3B, 3D, and 3E as examples of terminals 1a, 1b, 1c, 1d, and 1e at the search start time. An example of a music playback history at.

This example
(A) On the terminal 1a, no music is played back at 12:00 on December 14, 2004.
(B) At the terminal 1b, recently, the song A started to be played at 11:58 on December 14, 2004, and is being played at 12:00 on December 14, 2004.
(C) At the terminal 1c, recently, the song A starts to be played at 11:56 on December 14, 2004 and is being played at 12:00 on December 14, 2004.
(D) The terminal 1d played the song A from 9:23 to 9:29 on December 14, 2004, but played the song K at 12:00 on December 14, 2004. Inside,
(E) The terminal 1e played the song C on December 12, 2004, but at 12:00 on December 14, 2004, no song was played.
Is the case.

  As described above, as the music playback history, the music name (song ID), the playback start time and the playback end time of the music are recorded, but the playback is ended at the playback end time for the currently playing music. Sometimes filled in. Therefore, the music whose playback end time is not entered is currently being played back.

  However, it is not necessary to store all of the past playback histories as the music playback history, and only the most recent (latest) playback history may be stored.

  In the example of FIG. 3, the latest music reproduction history at each of the other terminals (terminals 1b, 1c, 1d, and 1e) is as shown in each stage of FIG.

  In addition, the latest reproduction history of the song A at each other terminal is as shown in each stage of FIG. 5, the music being reproduced at each other terminal at the search start time (time), and the reproduction start thereof The time is as shown in each stage of FIG.

  In addition, as an opportunity for the terminal 1a to start a search, a case where the terminal 1a starts a search each time according to an instruction of the user of the terminal 1a, a regular time interval, or a predetermined time In addition, any of the cases where the terminal 1a starts the search automatically may be used.

(2-2. First example of music playback method)
As a method of the present invention, it can be considered that when the search is started, the user of the terminal 1a has determined whether or not the song to be listened to is particularly determined. In this case, it is more likely that the user of the terminal 1a can listen to the same song as other users at the same time as compared to the case where the song to be listened to is determined.

<2-2-1. Search other terminals and select music>
In this case, the terminal 1a first searches for another terminal that is playing any of the music pieces. Specifically, for each of the other terminals (terminals 1b, 1c, 1d, and 1e), the music playback history as shown in FIGS. Request the latest music playback history as shown in the table.

  On the other hand, each other terminal receives the music reproduction history as shown in FIGS. 3B to 3E or the latest music reproduction history as shown in each stage of FIG. Send to 1a.

  The transmitted music reproduction history is displayed on the display unit 26 shown in FIG. 2 of the terminal 1a by the control unit 10 shown in FIG. 2 of the terminal 1a. You can know if it is playing.

  Specifically, in the above example, each of the other terminals (terminal ID for identifying each other terminal or associated with the other terminal as shown in FIG. 6 is obtained from the latest music reproduction history as shown in each stage of FIG. Terminal name or user name) and the name of the song being played on each other terminal (terminal 1b is song A, terminal 1c is song A, terminal 1d is song K, and terminal 1e is not playing).

  The user of the terminal 1a selects the music he / she wants to listen to by looking at the display. In the above example, the song A being played back by the terminals 1b and 1c or the song K being played by the terminal 1d is selected. However, in practice, the number of other terminals that can communicate with the terminal 1a is larger. If there are many and the number of the music currently reproduced | regenerated in any other terminal, the user of the terminal 1a can select the music which he wants to listen from among more music.

<2-2-2. Select other terminal>
In the above example, hereinafter, it is assumed that the user of the terminal 1a has selected the song A being played on the terminals 1b and 1c as the song to be played simultaneously with the other terminals.

  When the user of the terminal 1a selects the song A in this way by operating the operation unit 24 shown in FIG. 2 of the terminal 1a, the control unit 10 shown in FIG. Since there are two other terminals, terminals 1b and 1c, the remaining playback time or the elapsed playback time is calculated for each other terminal, and the remaining playback time is the longest (the lowest playback elapsed time). At the same time as the terminal 1a, it is selected as another terminal for reproducing the song A.

The search start time (in the above example, 12:00 on December 14, 2004), and the playback start time, playback elapsed time, and remaining playback time on the terminal that is playing back at this time, And between the total playback time,
Remaining playback time = Total playback time-Elapsed playback time (1)
Elapsed playback time = search start time-playback start time (2)
Remaining playback time = total playback time− (search start time−playback start time) (3)
There is a relationship.

  Then, as shown in FIGS. 7 and 8, for the music A that is being played on the terminals 1b and 1c at the start of the search, the playback elapsed time is 2 minutes on the terminal 1b. The remaining time is 4 minutes. In the terminal 1c, the elapsed playback time is 4 minutes and the remaining playback time is 2 minutes.

  Therefore, the control unit 10 of the terminal 1a selects the terminal 1b as another terminal that plays the music piece A simultaneously with the terminal 1a.

  In this case, when the clock circuit 31 shown in FIG. 2 of each terminal is synchronously controlled and the wireless network system is configured so that the time at each terminal coincides, the equation (2) or the equation (3) is used. It is possible to directly calculate the elapsed playback time or the remaining playback time.

  On the other hand, when the clock circuit 31 of each terminal is not synchronously controlled and there is a possibility that the time at each terminal is shifted, each of the other terminals (terminals 1b, 1c, 1d and 1e) as described above. When transmitting the music playback history to the terminal 1a, the current time at each other terminal is transmitted to the terminal 1a at the same time, and the terminal 1a shows the difference (difference time) between the current time at the terminal 1a and the current time at the terminal 1a. After calculating and correcting the playback start time at each other terminal so as to match the time at the own terminal (terminal 1a), the elapsed playback time or the remaining playback time is calculated by formula (2) or formula (3). Configure the system to do so.

  If music information such as the total playback time of the music A selected by the user at the terminal 1a as described above is not stored in the storage device unit 22 shown in FIG. 2 of the terminal 1a, the music A The system may be configured so as to request the terminal 1b or 1c that is playing the information to provide information indicating the total reproduction time of the song A.

  Further, in this manner, in the terminal 1a, the other terminal with the longest remaining reproduction time (the shortest elapsed playback time) is selected as the other terminal that simultaneously plays the music piece A. The music playback history transmitted to the terminal 1a may be the name of the music being played, the elapsed playback time or remaining playback time, and the total playback time when the other terminal is playing back the music.

<2-2-3. Simultaneous playback>
As described above, when the terminal 1a is playing the song A selected by the user of the terminal 1a and selects the terminal 1b as the other terminal having the longest remaining playback time (the shortest elapsed playback time), The song A is reproduced simultaneously with the terminal 1b.

  At this time, as shown in FIG. 8, the terminal 1a reproduces the song A from the position being reproduced by the terminal 1b, and the terminal 1b continues the reproduction of the song A as it is. Therefore, it does not hinder the appreciation of the music A by the user of the terminal 1b.

  In the above time and time, only the unit of “minute” is shown for the sake of convenience, but in practice it is desirable to consider up to the unit of “second”. In consideration of the unit of “second”, the playback start time of the music piece A on the terminal 1a may be delayed with respect to the search start time by executing each processing as described above. In consideration of the above, the position of the song A when the playback of the song A is started on the terminal 1a may be determined.

  The music data of the music A for playback on the terminal 1a may be read from the storage device 22 of the terminal 1a as long as it is stored in the storage device 22 of the terminal 1a, but is not stored in the storage device 22 of the terminal 1a. Of course, even when the data is stored in the storage device unit 22 of the terminal 1a, the system can be configured so that the terminal 1b transmits the data and the transmission / reception unit 35 of the terminal 1a receives the data.

  As described above, the user of the terminal 1a listens to the song A, which is in common with the user of the terminal 1b, for a long time as long as possible, so that the user of the terminal 1a A chance to communicate with the user 1 can be obtained, and communication with the user of the terminal 1b can be achieved by exchanging the feeling of the song A with a message (email).

<2-2-4. Consent to simultaneous playback>
In the above example, another user (the user of the terminal 1b, 1c, 1d, or 1e) may want to refuse simultaneous playback depending on the situation at that time. Therefore, the system can be configured so that other users can refuse simultaneous playback.

  As a method for that purpose, for example, when the search by the terminal 1a is started, there is a request for information provision from the terminal 1a to the display unit 26 shown in FIG. 2 of each other terminal (terminals 1b, 1c, 1d and 1e). In response to this, the user of each other terminal can instruct “YES” or “NO” to each other terminal (own terminal), and the user instructs “YES”. If the music playback history is provided from the user's terminal to the terminal 1a as described above, and the user instructs “NO”, the user's terminal cannot respond to the terminal 1a. Configure the system to be notified.

  In this case, the user of the terminal 1a and the terminal 1a exclude the other terminal that did not respond to the request, select the music, select the other terminal, and select the other terminal at the same time as described above. Play the music you played.

  Further, as another method regarding whether or not to permit simultaneous playback, as described above, the terminal 1a selects a music piece, selects another terminal, and then consents to simultaneously play the selected music piece on the selected other terminal. As a result, the display 26 of the selected other terminal indicates that there has been a request for simultaneous playback from the terminal 1a, and the user of the selected other terminal The system is configured so that “YES” or “NO” can be instructed.

  In this case, in the above example, when the user of the terminal 1b instructs “NO”, the terminal 1a reproduces the terminal 1c having the remaining remaining reproduction time of the song A next to the terminal 1b and the song A simultaneously. The system is configured so as to request the terminal 1c to play the song A at the same time.

<2-2-5. A series of processing at each terminal>
FIG. 9, FIG. 10 and FIG. 11 show an example of a series of processing executed by the control unit 10 of each terminal when music is played by the above-described method.

  In a state where a wireless network is formed between the terminal 1a and the terminals 1b, 1c, 1d, and 1e, first, the terminal 1a starts the search in step 41 as described above, and the terminals 1b, 1c, 1d as described above. And 1e are requested to provide the music playback history, and in response to this, the terminals 1b, 1c, 1d and 1e respectively receive the music playback history at their own terminals in steps 51, 61, 71 and 81, respectively. Is transmitted to the terminal 1a.

  In step 42, the terminal 1 a receives the music reproduction history, searches for other terminals that are reproducing music, and further displays the music that is being reproduced in each other terminal on the display unit 26 in step 43.

  Next, in step 44, the terminal 1a selects one piece of music being played on any of the other terminals according to the user's operation, and in step 45, the selected music piece (song A in the above example). Is calculated for each remaining terminal (terminals 1b and 1c in the above example), and in step 46, the remaining reproduction time is the longest (reproduction elapsed time is the shortest). Another terminal (terminal 1b in the above example) is selected.

  Next, in step 47, the terminal 1a asks the selected other terminal for permission to simultaneously play the music being played on the other terminal. In the above example, the terminal 1b is asked for consent to simultaneously play the song A.

  When the user of the terminal 1b accepts the simultaneous reproduction, the terminal 1b notifies the terminal 1a that the simultaneous reproduction is accepted in step 57, and the terminal 1a reproduces the music piece A simultaneously with the terminal 1b in step 48. The terminal 1b continues to play the song A in step 58, and the terminals 1a and 1b execute chats such as message (mail) and information exchange in steps 49 and 59.

  Although omitted in FIGS. 9 to 11, when the user of the terminal 1 b does not accept the simultaneous playback, as described above, the terminal 1 a reselects another terminal that simultaneously plays the music.

(2-3. Second Example of Music Playback Method)
The first example described above is a case in which the user of the terminal 1a has not decided the song that the terminal 1a particularly wants to listen to at the start of the search. Good.

  In this case, the user wants to listen to the terminal 1a instructing the terminal 1a each time, or registering in advance.

  In this case, the terminal 1a asks each other terminal (terminals 1b, 1c, 1d, and 1e) whether or not the instruction or registered music, for example, music A is being played, and plays it. When it is in the middle, it is requested to provide information indicating the playback start time, the elapsed playback time or the remaining playback time as the playback history.

  On the other hand, each other terminal transmits a message to that effect when the music is being played and the above-described playback history to the terminal 1a, and notifies the terminal 1a to that effect when the music is not being played. .

  Specifically, in the above example, when the music piece A is designated by the terminal 1a, the terminal 1b sends the reproduction start time (December 14, 2004 11:58), the reproduction elapsed time of the music piece A being reproduced. (2 minutes) or information indicating the remaining playback time (4 minutes) is transmitted, and the terminal 1c plays back the playback start time (11:56 on December 14, 2004) and elapsed playback time of the song A being played back. (4 minutes) or information indicating the remaining reproduction time (2 minutes) is transmitted, and the terminals 1d and 1e notify that the song A is not being reproduced. The time at each terminal is the same as in the first example.

  When the terminal 1a receives a response from each other terminal, the terminal 1a is reproducing the song A and playing the song A at the same time as the other terminal that has the longest remaining playback time (the shortest elapsed playback time). Choose as. Specifically, in the above example, the terminal 1b is selected.

  Next, at the terminal 1a, the music piece A is reproduced from the position being reproduced at the terminal 1b. Also in this case, the terminal 1b continues the reproduction of the music piece A as it is. Therefore, it does not hinder the appreciation of the music A by the user of the terminal 1b.

  Whether or not to permit simultaneous playback is the same as in the first example.

(2-4. When selecting another terminal whose remaining playback time is a predetermined value or more)
In the first and second examples described above, when there are a plurality of other terminals that are playing back the selected or designated song A, the other terminal with the longest remaining playback time is played back at the same time. In the case of selection as a terminal, the system may be configured to select another terminal whose remaining reproduction time is equal to or greater than a predetermined value as a terminal for simultaneously reproducing the song A.

  The remaining reproduction time is a predetermined value or more, for example, the remaining reproduction time is 2 minutes or more, for example, or the ratio of the remaining reproduction time to the total reproduction time is 33.3, for example. % (1/3) or more, that is, a predetermined ratio or more. The predetermined time or the predetermined ratio may be set for each music piece or set by a user who desires simultaneous reproduction of the music piece.

  When there are a plurality of other terminals for which the remaining playback time of the music is a predetermined value or more, for example, the system may be configured to select all of the plurality of other terminals as terminals for simultaneously playing the music. Yes, according to this, it is possible to communicate among three or more users including the user of the terminal 1a. In this case, the position where the reproduction of the music piece is started at the terminal 1a may be, for example, the position where the reproduction remaining time is being reproduced at the other terminal having the longest remaining reproduction time.
