Technical scheme is described in detail with specifically embodiment below.These specific implementations below
Example can be combined with each other, and may be repeated no more for same or analogous concept or process in some embodiments.
The embodiment of the present invention is directed to intelligent television when playing some multimedia resources, if these multimedia resources do not have
Temporal information can not just show the problem of temporal information, propose a kind of method that offer temporal information is handled by terminal itself.
Fig. 1 is the multimedia resource play handling method schematic flow sheet that one embodiment of the invention provides.This method is held
Row main body can be the terminal that intelligent television, mobile phone, tablet personal computer etc. have multi-media player function.As shown in figure 1, this method
Including：
S101, obtain multimedia resource to be played.
Here multimedia resource can be the resource that any terminal can play, such as video resource, audio resource, dynamic
Figure etc., is not limited herein.These resources can be obtained by internet, can be obtained, be can also be by set-top box signal
Mobile device is transmitted by the interface of response and obtained, and the present embodiment is not restricted.
S102, calculate the timestamp information per frame data in multimedia resource to be played.
Multimedia resource is made up of continuous multiframe, can be obtained in multimedia resource to be played per frame data by calculating
Timestamp information.
S103, by timestamp information write corresponding to frame data, the multimedia resource to be played after being handled.
S104, play the multimedia resource to be played after the processing, the above-mentioned timestamp information of simultaneous display.
The every frame time stamp information that will be calculated is written in corresponding every frame data, to be played more after formation processing
Media resource so that temporal information is included in the multimedia resource to be played after processing, waits to broadcast so after the processing is played
When putting multimedia resource, will simultaneous display go out timestamp information.
Here the timestamp information shown can be currently playing time point, can also calculate the total of multimedia resource
Duration is shown, such as is shown：25/1200, represent multimedia resource total duration 1200 seconds, currently playing frame is the 25th second.
In the present embodiment, after obtaining multimedia resource to be played, calculate and obtain in multimedia resource to be played per frame data
Timestamp information, by timestamp information write corresponding to frame data, the multimedia resource to be played after being handled, Jin Erbo
Put the multimedia resource to be played after the processing, the above-mentioned timestamp information of simultaneous display.Realize after getting multimedia resource,
The timestamp information of every frame data can be further calculated, to determine the timestamp information of multimedia resource, so that it is more playing
During media resource can with simultaneous display timestamp information, even if so multimedia resource to be played does not include temporal information originally,
User is in viewing it can also be seen that temporal information, improves Consumer's Experience.
It is alternatively possible to before the timestamp information in calculating multimedia resource to be played per frame data, determine above-mentioned
Temporal information is not included in multimedia resource to be played.Usually, the temporal information that user sees in terminal in the prior art,
Typically all carry in every frame data of multimedia resource to be played.For example, all comprising i.e. timestamp in per frame data
(Presentation Time Stamp, abbreviation PTS) information, PTS correspond to current reproduction time, and player can be from more
PTS information is read in media resource, is shown to user.The method that the present embodiment provides can be terminal it is determined that to be played more
When not including temporal information in media resource, calculating timestamp information is initiated self, then write every frame data.
Alternatively, when above-mentioned multimedia resource to be played is video resource, image resource and audio resource can be decoded as.
Above-mentioned multimedia resource to be played can also be single image resource or single audio resource.
In the case of media resource to be played includes image resource, for example, multimedia resource to be played be video resource or
During single image resource, multimedia resource to be played includes：Multiple continuous data sequences (Sequence), each data sequence
Row include image sets (Group Of Picture, abbreviation GOP).
Fig. 2 is the multimedia resource play handling method schematic flow sheet that another embodiment of the present invention provides.Such as Fig. 2 institutes
Show, this method includes：
Image sets in S201, acquisition multimedia resource to be played.
S202, parse image sets time code data domain, the time code data domain include the image sets temporal information and
Frame number information.
S203, according to time code data domain, calculate the timestamp information per frame data in multimedia resource to be played.
Fig. 3 is frame structure schematic diagram in multimedia resource play handling method provided by the invention.It is using image resource
Exemplified by state motion picture expert group version (Moving Picture Experts Group, MPEG), as shown in figure 3, MPEG is by multiple continuous
Data sequence composition.Each data sequence includes：Sequence heads (Header) and Sequence data volumes (Body) two
Most of, each Sequence Body is made up of continuous GOP, and it is big that each GOP includes GOP Header and GOP Body two
Part.GOP Header include timing code (Time Code) data field, also referred to as time-domain.Wherein, Time Code are included：It is small
When (Hours), minute (Minutes), the data field such as second (Seconds) and picture number (i.e. frame number, Pictures), GOP Body
Include specific image (Picture) data (frame data).
Specifically, for some sequence, the initial time of GOP in the sequence can be obtained according to Time Code data fields
(second)=Hours*3600+Minutes*60+Seconds.And then obtain the timestamp information per frame data further according to picture number.
Correspondingly, can obtain the image in GOP Body by frame data corresponding to timestamp information write-in
(Picture) data, timestamp information is write into Picture data.
Alternatively, in the case of media resource to be played includes audio resource, for example, multimedia resource to be played be regarding
When frequency resource or single audio resource, the timestamp information in above-mentioned calculating multimedia resource to be played per frame data can be with
For：Obtain audio resource in per frame data sample rate and sampling number, according in audio resource per frame data sample rate and
Sampling number, calculate the timestamp information per frame data in audio resource.
Such as equation below can be utilized to calculate the timestamp information in audio resource per frame data：
The PTS (second) of the voice data of n-th frame=(n-1) SampleNumber/SampleRate
Wherein：SampleRate is sample rate, is the number for extracting sample sound each second, such as distortionless feelings of sound
Condition down-sampling rate can be 40kHz (sampling 40000 times for one second), and this can read out from the data of audio resource.
SampleNumber is the number of samples included per frame data, such as：Dynamic image expert's compression standard audio aspect 3
The voice data of (Moving Picture Experts Group Audio Layer III, abbreviation mp3) form
SampleNumber is generally 1152 samplings, and this be able to can read out from the data of audio resource.
If above-mentioned multimedia resource is video resource, that is, include：Image resource and audio resource, then can use above-mentioned
Method respectively in every frame data of the every frame data and audio resource of image resource the write time stab information, and then further according to when
Between stab information by after image resource and audio resource synchronization, obtain new video resource, can be automatic when playing new video resource
Presentation Time Stamp information.The synchronization of image resource and audio resource can also be so carried out using timestamp information.
Or the timestamp information of every frame data of image resource can also be only obtained, according to it when playing video resource
The timestamp simultaneous display timestamp information of middle image resource.
