For making the purpose, technical solutions and advantages of the present invention clear more understandable,, the present invention is described in further details below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
At first see also Fig. 1, Fig. 1 is the flow chart that the present invention is based on the synchronous play method for mobile phones of wireless transmission.
The flow process of flow chart that the present invention is based on the synchronous play method for mobile phones of wireless transmission is such:
After originating end mobile phone and receiving terminal mobile phone are realized being connected by wireless connect technology, the originating end mobile phone is initiated interaction entertainment and is invited, the receiving terminal mobile phone judges whether to accept the invitation after receiving requirement, accept the invitation if select, then by originating end cellphone subscriber manual creation and send the invitation of interaction entertainment music track tabulation, wireless transmission is given the receiving terminal mobile phone simultaneously, the automatic reception of receiving terminal mobile phone is after this interaction entertainment music track tabulation, send and confirm to the originating end mobile phone, originating end mobile phone backstage is initiated relative synchronization mechanism debug signal automatically and is given the receiving terminal mobile phone, the backstage automatic reception of receiving terminal mobile phone is behind this signal, confirm synchronization time difference, send a time difference affirmation feedback for afterwards the originating end mobile phone, the originating end mobile phone carries out the countdown of mobile phone separately to the reproduction time of agreement simultaneously with the receiving terminal mobile phone after obtaining this feedback, music according in the playing back music tabulation simultaneously that puts in order realizes interactive.
During playing, originating end mobile phone and receiving terminal mobile phone mobile phone need carry out the lock in time on a backstage at regular intervals to be proofreaied and correct, thereby the amusement that guarantees mobile phone is synchronous, and music is in step with.
In the present embodiment, only provide the situation of an originating end mobile phone and a receiving terminal mobile phone, but be not limited in this, receiving terminal mobile phone wherein also can be a plurality of, to reach the common effect of playing simultaneously of multi-section mobile phone.
Present technique makes full use of under the prerequisite of existing wireless communications technology, amusement function maximization with two mobile phones, the prior art that is applied to comprises the existing mature technology of wireless communication technology agreement such as Bluetooth transmission protocol or infrared transmission agreement, MP3 music player, by these prior aries, the synchronization mechanism that cooperates each mobile phone end again, thus realize for the antiphonal singing of specific MP3 or the function of chorusing.Here the synchronization mechanism of Ying Yonging mainly is the maintenance of the time difference of the local time stamp by two handheld devices, thus keep to the musical time frame play synchronously, in case the time of occurrence difference is asynchronous, the instant adjustment.
See also Fig. 2 again, Fig. 2 is the flow chart that the present invention is based on originating end in the synchronous play method for mobile phones of wireless transmission.
The flow process of originating end is as follows:
When originating end initiates to start the invitation feedback that a timer is waited for the other side when synchronous amusement is invited,, think that then information dropout selects to send once more to invite if do not obtain any feedback at the appointed time.Behind the feedback information that obtains the other side, do further judgement, if the other side disagree with, then directly finish this invitation; If the other side confirms to agree to invite, then select to want the music list of synchronous amusement (will guarantee total simultaneously these files of both sides here, can be in advance send and realize by bluetooth) start timer simultaneously and wait for that the other side reaffirms, if it is overtime then select to send once more this music table, when the other side acknowledges receipt of music list, the backstage sends local timestamp at this moment, and the timestamp that starts timer reception the other side once more afterwards calculates locking phase to time difference Δ T1, sending 5 times afterwards at once continuously has the information of agreement music Ti start-up time and begin countdown preparation startup music after five information all sends end, if the reason that sends 5 times continuously is to consider have certain probability that information dropout can take place, can effectively prevent the generation of this type of problem like this.
See also Fig. 3 again, Fig. 3 is the flow chart that the present invention is based on receiving terminal in the synchronous play method for mobile phones of wireless transmission.
The flow process of receiving terminal is as follows:
Whether receiving terminal is waited for the message request of originating end, select afterwards to accept, if do not accept then notify originating end and directly finish this invitation; If wait the other side's music list sends affirmation OK then sends confirmation signal after information is accepted the invitation in transmission if affirmation is accepted the invitation, otherwise directly finishes this invitation; If confirmed music list then waited for that the synchronized timestamp signal of originating end sends simultaneously local time stamp after receiving, carrying out the time difference then immediately resolves and obtains locking phase to time difference Δ T1, wait for afterwards and receive music Ti start-up time that appoints that the other side initiates, when receiving this information for the first time, then start timer and start music after the time at Ti+ Δ T1, start timing simultaneously and stab receiving function, calculate and guarantee each Δ T1 that whether remains on lock in time relatively of two mobile phones.
Time-correcting method mentioned above, particular content is as follows:
Originating end mobile phone transmitting time is stabbed T1, receiving terminal mobile phone transmitting time is stabbed T2, and both sides' time difference Δ T1 is that relative time is poor, will keep this difference constant in synchronizing process, if another time difference Δ T2 in the synchronous playing process, occurs, the difference of it and Δ T1 so
Be the time numerical value that needs rectification, the originating end mobile phone is not done debugging, and the time debugging only takes place on the receiving terminal mobile phone.The work that the receiving terminal mobile phone will be done is exactly at once music to be carried out the F.F. of differential time when finding difference, here need this difference is only carried out interval setting, what we considered generally speaking is the minimum precision of F.F. of mobile phone music player, such as being X, sets so
The time the one F.F. X time in step of receiving terminal handset starting progress, this is in music and not obvious, the timestamp of both sides' mobile phone just sent once every 25 second time, was engraved in when guaranteeing to keep synchronously, realized that it all is the comparison trace that each time is revised.
The choosing method in each time interval that sends of the timestamp of both sides' mobile phone:
In order to guarantee the variation of contingent time difference Δ T in the music, therefore must be every the regular hour, the originating end mobile phone just sends the instant time stamp T 1 of originating end mobile phone one time will for the receiving terminal mobile phone, being time difference Δ T with the time stamp T 2 of receiving terminal mobile phone this locality calculates, in case find result of calculation time difference Δ T and result of calculation value of differing of last time, carry out time adjustment at once, bearing calibration reference technique main points " time-correcting method "
In order to guarantee that time difference changes the promptness that the back very first time finds, we are t at time interval of setting that originating end mobile phone transmitting time stabs to the receiving terminal mobile phone here, and value threshold value and the condition of t are as follows:
The timestamp that the originating end mobile phone sends for the first time is T1,
The timestamp that the receiving terminal mobile phone writes down oneself for the first time is T2,
Both sides are Δ T1 the primary time difference
If Δ T1=0s, then transmission time interval is t=60s;
If 0＜Δ T1＜1s, then transmission time interval is t=30 * Δ T1;
If 1s＜Δ T1＜15s, then transmission time interval is t=2 * Δ T1;
If 15s＜Δ T1＜30s, then transmission time interval is t=Δ T1;
If 30s＜Δ T1＜60s, then transmission time interval is t=1/2 * Δ T1;
If 60s＜Δ T1＜120s, then transmission time interval is t=1/5 * Δ T;
If 120s＜Δ T1＜240s, then transmission time interval is t=1/10 * Δ T;
If 240s＜Δ T1, then transmission time interval is t=30s;
By with the choosing of upper threshold value, be engraved in when realizing will guaranteeing mobile phone under the multiple situation and keep synchronously, realize that it all is more timely that each time is revised.
The file that the mobile phone above mentioned is play mainly is the mp3 music file, is described as follows for the making of antiphonal singing Mp3:
The MP3 song generally has two kinds of forms, and a kind of is that accompaniment tone and voice are to separate, and leaves different sound channels respectively in, and we only need to extract corresponding accompaniment tone and record again and to get final product; Also have and a kind ofly belong to that accompaniment tone and voice mixes, the sound of left and right acoustic channels is duplicate, but music editor's software is a lot of at present, can very easily make the antiphonal singing type that we need, be that each mobile phone is only played one's own that part of voice, only play corresponding accompaniment tone remaining time, such as " Hiroshima Mon Amour " of the uncivilian luxuriant and neat Qin of the mobile phone synchronous playing antiphonal singing of adopting synchronous broadcast method of the present invention:
The originating end mobile phone is sung boy student's part: you early should refuse the pursuit that I should not let alone me and stay the name of losing to the story that I thirst for
The receiving terminal mobile phone is play at this moment: the accompaniment of this section boy student part because of
