Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, hereinafter will be elaborated to embodiments of the invention in conjunction with the accompanying drawings.Need to prove that under the situation of not conflicting, embodiment among the application and the feature among the embodiment be combination in any mutually.
Fig. 1 is the schematic diagram of the playing device of media stream of the present invention, and as shown in Figure 1, the playing device of present embodiment comprises:
Whether detection module is used for the process at play multimedia stream, detect multi-medium data and lose;
Playing module is used for detecting under the situation that multi-medium data loses at described detection module, carries out quiet operation immediately.
Like this, the playing device of present embodiment is uttered long and high-pitched sounds not full-time just not can the generation of data.
In the present embodiment, described detection module also is used for after losing detecting multi-medium data, detects whether multi-medium data takes place in the given time to lose;
Described playing module also is used for detecting at described detection module and does not take place in the given time to continue to play described media stream under the situation that multi-medium data loses.
Like this, the quiet of long-time section just can not appear in the playing device of present embodiment, do not influence user's experience.
Fig. 2 is the flow chart of the player method of media stream of the present invention, and this method comprises following step:
S10, in the process of play multimedia stream, if detecting multi-medium data loses, then carry out quiet operation immediately.
Multi-medium data has a variety of packing forms, as transport stream (TS stream), MKV(Matroska Video File, video file format), AVI(Audio Video Interleaved, the Audio Video Interleaved form) etc., whether each packing form can be judged its data has and loses.Transport stream for example can be utilized the continuity_counter(continuous counter of transport stream packets) field judged whether loss of data.The continuity_counter field is the field of a 4bit, identical PID(Program Identifier, program identifier) this field of TS bag increase progressively continuously, return to 0 again after being incremented to 15.
Be example with the transport stream format below, the inventive method be described in detail, in the present embodiment, at first judging multi-medium data according to the continuity_counter field of transport stream has and loses, in the time of loss of data, quiet immediately, make the audio decoder module can not produce and utter long and high-pitched sounds; And then detect, if loss of data did not take place in a period of time, then open sound immediately and continue to play.
As shown in Figure 3, present embodiment comprises the steps:
Step 101 according to the PID of audio frequency, is got the value of the continuity_counter field of an audio TS bag;
Step 102 is got the value of the continuity_counter field of next audio TS bag;
Step 103, whether the continuity_counter field value of judging two TS bags is continuous, if discontinuous, the value of the continuity_counter field of promptly back TS bag is not to add 1 on previous basis, and packet loss has been described, the data disappearance is promptly arranged, then execution in step 104, if continuously, the value of the continuity_counter field of promptly back TS bag is to add 1 on previous basis, then explanation does not have packet loss, changes step 102;
Step 104, quiet immediately, avoided uttering long and high-pitched sounds, change step 105;
5 audio TS bags of continuous detecting again take place behind the packet loss in step 105, if these 5 TS bag the insides all do not have packet loss, then open sound again, continue to play, and change step 102 then.
In the step 105, being not limited to and detecting 5 audio TS bags, also can be other numbers.
Adopt method of the present invention can avoid the factor certificate to lose and uttering long and high-pitched sounds of causing, improve user experience.
One of ordinary skill in the art will appreciate that all or part of step in the said method can instruct related hardware to finish by program, described program can be stored in the computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of the foregoing description also can use one or more integrated circuits to realize.Correspondingly, each the module/unit in the foregoing description can adopt the form of hardware to realize, also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
Below only be the preferred embodiments of the present invention; certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
