Embodiments of the present invention, by the next channel data that is prepared in advance, make, when expectation is switched to next channel, can directly to it, plays, thereby greatly shorten time of switching channels, and then significantly promote user's experience.In another embodiment, by being provided for the timeout period of channel switching, change the channel of processing in back way, realized when switching fast and effectively reduced power consumption, this makes it possible to obtain good trading off between the time loss of switching channels and power consumption.In another execution mode, by the history based on channel switch request, occur that situation predicts in back way the channel of processing, channel is switched more intelligent and efficient.
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 2 shows the flow chart of the method 200 for playing stream media according to the embodiment of the present invention.As shown in Figure 2, in step S201, the data in all time slots of receiving stream media on frequency.Each specific frequency can receive several channels, in the present embodiment, is received in the data in all time slots on this frequency, the broadcasting after switching for channel.In another embodiment, the frame in all time slots on the frequency of receiving stream media place is deferred to China Mobile multimedia broadcasting CMMB standard.In step S202, the data that buffer memory receives, and parse respectively the respective frame of a plurality of channels.Wherein, for the data that receive, only carry out complexity and the parse operation much smaller than decoding consuming time, and it is not decoded.In step S203, only decode and play the frame of current channel.S202 is different from step, and decode operation is only corresponding to the frame of current channel.In another execution mode, H.264 standard is deferred in this decoding.
Although not shown in the drawings, in one embodiment, method 200 also comprises in response to the channel switch request that is switched to another channel, stops the decoding of the frame of current channel and broadcasting, and is new current channel by another channel fix.The method also comprises the frame of only decoding and playing new current channel.In the playing process of current channel, carry out the operation of above-mentioned steps S201-202, that is simultaneously, when playing, upgrade the data in institute's buffer memory all time slots of the Streaming Media through resolving on frequency.When receive from user be switched to the channel switch request of another channel time, by buffer memory the data through resolving of decoding, realized channel fast and switched, and then greatly promoted user's experience.
When promoting channel switch speed, another key issue is how when the channel of realizing approaching zero second switches, to reduce power consumption.If also make three playback engine all play when the operation that there is no switching channels, will cause huge waste to power.Therefore, in an embodiment of the invention, by within the specific time, when there is no the operation of switching channels, the channel that stops processing in back way, thus reduced power consumption.
The channel that Fig. 3 shows according to the embodiment of the present invention switches example.As shown in Figure 3, current broadcasting channel is channel _ 2, and previous channel is channel _ 1, and next channel is channel _ 3.When needs are switched to previous channel or next channel, in the situation that only have one for playing the data buffer of playback engine and user cache data of current channel, before being switched to channel _ 1 or channel _ 3, need to spend the several seconds to prepare data.If but there are three playback engine and three data buffers, according to above description, could realize the channel switching that approaches zero second.
Based on above-mentioned thought, method according to another implementation of the invention arranges timeout period by the operation for switching channels, can when the operation that there is no switching channels, avoid the work of backstage playback engine, and its crucial processing procedure is as follows:
1) application program arranges timeout period and starts backstage playback engine (for the playback engine of channel _ 1 and channel _ 3);
2) if do not receive channel switch request in timeout period, stop processing in back way the channel except current channel;
3), if application program is learnt the operation that has switching channels in this timeout period, such as the operation that is switched to channel _ 3, will stop for the playback engine of channel _ 1 and start the playback engine for channel _ 4, the timeout period of simultaneously resetting.Now, channel _ 3rd, current broadcasting channel.That is, if receive channel switch request in timeout period, the channel that change is processed in back way, and replacement timeout period;
4) if receiving channel switch request after timeout period, again process in back way the channel except current channel, and replacement timeout period.
Owing to processing 4), the method is not the real operation that approaches the switching channels of zero second, but for realize approach the switching channels of zero second and save power be one compromise.Special timeout period can be set reduce to process 4) probability that occurs.
In another execution mode, also can occur when again situation is predicted according to the history of channel switch request and process in back way the channel except current channel and replacement timeout period.
Fig. 4 shows the block diagram of the equipment 400 for playing stream media according to the embodiment of the present invention.As shown in Figure 4, equipment 400 comprises control engine 401, a plurality of data buffer 402-1 to 402-n, and a plurality of playback engine 403-1 to 403-n.Wherein, control engine 401 and be configured to the data in all time slots of receiving stream media on frequency, a plurality of playback engine 403-1 to 403-n are configured to the data that buffer memory receives, and parse respectively the respective frame of a plurality of channels, and a plurality of playback engine 403-1 to 403-n is configured to only to decode and plays the frame of current channel.Particularly, first, application plays device request program is play, and then control a plurality of channels of engine configuration, and hardware layer will configure to receive data with this.Secondly, after DSR, control engine a plurality of channel datas are copied in a plurality of data buffers, and require a plurality of playback engine to extract these data.Then, playback engine is extracted decoder by these data, and is ready for broadcasting.Finally, application plays device is play the current channel program corresponding with playback engine.Now, if expectation is switched to next channel, only needs to select another playback engine, and do not need repetition said process.Therefore the time that, switching broadcasting channel spends is almost insignificant.
In another embodiment, in response to the channel switch request that is switched to another channel, controlling engine is also configured to stop to the decoding of the frame of current channel and broadcasting, and by another channel fix, be new current channel, playback engine is also configured to only to decode and plays the frame of new current channel.
