Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows and is suitable for system configuration of the present invention, and client 100 can be to support the various terminals of Brew, as mobile phone, PDA (Personal Digital Assistant, personal digital assistant) etc.Client 100 is undertaken alternately by IP network and server, the stream medium data that Download Server provides, and the broadcast of stream medium data controlled, comprise playing/stop, suspending/continue and skip forward/back.Server sends media data to client 100, comprises real-time live transfer server 200 and on-demand content server 300, wherein:
Live transfer server 200 receives the stream medium data of media broadcast such as broadcasting station, TV freely in real time, according to the request of client 100, data is carried out code conversion then, and the data after will encoding at last send to client 100.The broadcast mode of this Streaming Media generally is used for the service of live classes such as broadcasting station, TV.Client 100 can only be play according to the time series that live transfer server 200 sends data, can not carry out the skip forward/back operation.
On-demand content server 300 provides non real-time stream medium data to the user, and the broadcast mode of this Streaming Media generally is used for the service of program request classes such as music, film, and user's interactivity and controlled stronger can be carried out operations such as skip forward/back.
Because the play property of stream medium data is to receive and play and carry out simultaneously, so the present invention creates the ring-type buffer memory that length is L in client 100, as shown in Figure 2.Be kept at after stream medium data receives in this buffer memory, play-over the data in this buffer memory during broadcast, D1 is the data length of storing in the buffer memory, and D2 is the receivable buffer storage length of residue.Receive and play a shared ring-type buffer memory and can significantly reduce the system resources consumption that produces owing to memory copying.
In the present invention, because data playback and receive to use same buffer memory, so playing pointer is set and two pointers of reception pointer are used for identifying current receiving position and current play position respectively.Playing pointer indicates the cache location that current data is played to, and reception pointer indicates the cache location that current data receives.Because buffer memory is ring-type, when playing pointer or reception pointer surpass buffer storage length L, then turn to 0 position of buffer memory automatically, so playing pointer and reception pointer there are two kinds of relations, as shown in Figure 2.
" ping-pong " in receive and play, the present invention is provided with four and is used for the Play Control threshold values that control data receives and plays, promptly starts to play threshold value, start receive threshold, stop to play threshold value and stop receive threshold, wherein:
Start to play threshold value, be used for broadcast stop or halted state under, determine after receiving how many data the broadcast of log-on data;
Start receive threshold, be used for reception stop or halted state under, after determining to have play how many data, the reception of log-on data;
Stop to play threshold value, be used under broadcast state, determine that how many times remaining data is, stops or suspending the broadcast of data;
Stop receive threshold, be used under accepting state, determine that how many times remaining data is, stops or suspending the reception of data.
Below data are play and received to client 100 process be elaborated:
(1) initial start is play
When client 100 started media play, the initial play state was for stopping, but in the ring-type buffer memory played data do not arranged as yet, and playing pointer and reception pointer all point to 0 position of buffer memory.After data began to receive, reception pointer moved forward, when the data length D1 in the buffer memory plays threshold value more than or equal to startup, and the then broadcast of log-on data, playing pointer begins to move forward.
(2) suspend broadcast
When Network Transmission was obstructed, at this moment the broadcasting speed of data just needed to suspend data playback greater than inbound pacing, waits replenishing of pending data.When the data length D1 in the buffer memory when stopping to play threshold value, the data that client 100 can played in order be received.Otherwise client 100 is suspended the broadcast of data, waits for receiving enough data.
(3) start broadcast
Play owing to behind the data deficiency time-out, continue to receive data.When the data length D1 that receives in the buffer memory plays threshold value more than or equal to startup, start and continue to play.
(4) suspend reception
When Network Transmission was unobstructed, the inbound pacing of data was greater than broadcasting speed, and annular buffer memory is filled full, needed to suspend to receive, and waited for that clearance spaces appears in buffer memory.When the data length D1 in the buffer memory when stopping receive threshold, the current reception pointer of client 100 records, send time-out to server and send request of data, and abandon the follow-up data that receive, thereby suspend the reception of data, reception pointer stops to move, and waits for that data playback produces free memory.
(5) start reception
After Data Receiving stopped, along with the carrying out of data playback, playing pointer constantly advanced, thereby produced new received space.When the data length D1 in the buffer memory when starting receive threshold, client 100 sends to server and continues to send request of data, indicate and suspended the Data Position that receives last time, request server suspended the Data Position that receives from last time and continues to send data, and client 100 continues to receive data.
When client 100 starts streaming media playing, at first select the Media Stream that will play, game server receives data to server requests then.After server was received the Data Receiving request of client 100, beginning was to the media data flow of client 100 transmission appointments, and client 100 begins to play after receiving media data.When client 100 stops media play, stop data sending request to the server transmission, stop the broadcast of local data then.
Among the step S301, client 100 is suspended played data;
Among the step S302, the playing pointer of buffer memory stops to move, but the Data Receiving of client 100 does not stop at this moment, and reception pointer continues to move forward;
Among the step S303, when the data length in the buffer memory satisfied the time-out receive threshold, then execution in step S304 suspended Data Receiving, and reception pointer stops to move.
Fig. 4 shows the DRP data reception process of client 100 under the continuation broadcast state:
Among the step S401, client 100 continues played data;
Among the step S402, playing pointer begins to move;
Among the step S403, when the data length in the buffer memory satisfied the startup receive threshold, execution in step S404 continued the reception of data, and reception pointer begins to move.
Skip forward/back provides the function of quick positioning playing position for the user, and this function is only effective to a broadcasting flow-medium, and for real-time programme televised live, the user can't carry out skip forward/back.
Skip forward/back is actually the process of reorientating to reception/played data, and Fig. 5 shows the realization flow that client 100 is carried out the skip forward/back operation:
Among the step S501, client 100 navigates to the position that needs broadcast according to user's operation;
Among the step S502, search play position whether in buffer memory, if, execution in step S503 then, otherwise execution in step S504;
Among the step S503, start playing pointer, playing pointer is directly navigated to play position;
Among the step S504, suspend current data playback and reception;
Among the step S505, playing pointer and reception pointer are returned to initial condition, i.e. the starting position of buffer memory;
Among the step S506, send request to server, request server sends data from the play position of appointment;
Among the step S507, receive the also data of caching server transmission;
Among the step S508, when judging whether satisfy to start to play threshold value, be execution in step S509 then, otherwise continue execution in step S506;
Among the step S509, begin played data from the play position of user's appointment.
Fig. 6 shows the pie graph of the client 100 based on the Brew play stream media data provided by the invention, for the purpose of simplifying the description, only shows part related to the present invention.Simultaneously, repeat no more for the content of above having described.
Ring-type buffer 101 is used for cache client 100 by the stream medium data of IP network from live transfer server 200 or 300 downloads of on-demand content server.Ring-type buffer 101 has playing pointer and two pointers of reception pointer, is respectively applied for the cache location that the indication cache location that is played to of current data and current data receive.
