Fig. 2 is the flow chart of processing method one embodiment of video playback of the present invention.Fig. 3 is the handling process schematic diagram of processing method one embodiment of video playback of the present invention.Fig. 4 is the video image resolution format transition diagram in the inventive method one embodiment.As in figure 2 it is shown, the present embodiment is applied in TV to illustrate with the processing method of this video playback, method includes:
Step 201, obtain the decoded video image that video to be played is corresponding；
Step 202, before the resolution format of every frame video image is converted to the second resolution form mated with display screen, when the resolution format of every frame video image is with first resolution format mismatching, the resolution format of every frame video image is converted to first resolution form；
Wherein, the video image being converted to first resolution form includes effective pixel points and by the duplicated pixel of effective pixel points；Effective pixel points is the pixel in the video image before conversion.
Specifically, the same video content in server is likely to preserve different resolution form (its frame per second will not change, and is only the difference of resolution), includes but not limited to following several, every kind of resolution correspondence one pattern:
3840 × 2160-----pattern 1
2880 × 1440-----pattern 2

When the application scenarios of video request program plays out process, first obtain the decoded video image that the video to be played of user's request is corresponding；Can be that in Fig. 3, decoder module is decoded obtaining video image；
The video to be played obtained can be the video signal of the resolution format that server mates according to the network bandwidth with active user of the network bandwidth active push of active user, it is also possible to be the video signal of the SOC resolution format mated to the network bandwidth with active user of server request according to the network bandwidth of the active user of monitoring.
For decoded video image, before the resolution format of every frame video image is converted to the second resolution form mated with display screen, when the resolution format of every frame video image is with first resolution format mismatching, every frame video image is sequentially carried out resolution format conversion, unified for first resolution form, Fig. 3 illustrate only 3 frame video image F1, F2, F3, video image after conversion F1 ' as shown in Figure 3, F2 ', F3 ', the video image of all the other frames is similar, decoded all video images are sequentially carried out resolution format conversion.
Wherein, the effective pixel points in original video image can simply be replicated by transformational rule.
Due to video source can according to the network bandwidth real-time transform resolution of user, therefore through the resolution of the decoded video image of decoder be not skimble-scamble in the same time, it is therefore desirable to be processed into unified first resolution form through format converting module.
Such as, first resolution form is assumed to be 3840 × 2160, the resolution format of decoded video image is pattern 4, the video image by 1920 × 1080 resolution is then needed to be converted to the video image of 3840 × 2160 resolution, specifically can be through the pixel by the every a line in original video image and replicate 1 row respectively, generate 2160 row pixels, and the pixel of the every string in the video image after process is replicated 3 row, generate 3840 row pixels, be ultimately converted to the video image of 3840 × 2160；In other embodiments of the present invention, it is also possible to carrying out resolution format conversion by other means, this is not limited by the present invention.
As shown in Figure 4, two frame video image resolution formats are 1920 × 1080 above, first resolution form is also 1920 × 1080,3rd frame video image resolution format is 1280 × 720, first resolution form is 1920 × 1080, then the 3rd frame video image is carried out resolution format conversion then again output carry out image quality process.
Or, first resolution form is assumed to be 3840 × 2160, the resolution format of decoded video image is different, the resolution format assuming front 3 frame video images is pattern 1, 4th frame starts resolution format and becomes pattern 4, then first carry out resolution format conversion, the resolution format of this resolution format with above several frame video images is unified, although being now also required to certain process time, but owing to transformational rule is relatively simple, processing speed is very fast, it is then passed through image procossing VDP/DDP module, display processing module, the resolution of the video signal after display screen is stable, do not result in blank screen problem caused after changing in playing process because of resolution.
The processing method of the video playback that the present embodiment provides, the decoded video image corresponding by obtaining video to be played；Then before the resolution format of video image described in every frame is converted to the second resolution form mated with display screen, when the resolution format of video image described in every frame and first resolution format mismatching, the resolution format of video image described in every frame is converted to first resolution form, owing to the resolution format of video image having been unified before being converted to the second resolution form mated with display screen, transformation process is relatively easy, simply effective pixel points is replicated, and when being converted to the second resolution form mated with display screen due to without switching format conversion algorithms, the process time is shorter, therefore blank screen signal need not be inserted, compared with prior art, do not result in blank screen problem caused after changing in playing process because of resolution.
On the basis of above-described embodiment, the resolution format of every frame video image is converted to the second resolution form mated with display screen, specifically can be accomplished in that
According to image scaling interpolation algorithm, the first resolution form of the every frame video image after conversion is converted to the second resolution form mated with display screen.
Such as, the second resolution form mated with display screen is assumed to be 3840 × 2160, unified first resolution form is pattern 4, then need the video image by 1920 × 1080 resolution to be converted to the video image of 3840 × 2160 resolution, can be specifically calculate, through interpolation algorithm, the mode conversion resolution form filling a new pixel between original video image neighbor pixel；In other embodiments of the present invention, it is also possible to carrying out resolution format conversion by other algorithms, this is not limited by the present invention.
Image scaling interpolation algorithm, including such as linear interpolation algorithm, arest neighbors interpolation algorithm, bilinear interpolation value-based algorithm etc..
Or, the second resolution form mated with display screen is assumed to be 1920 × 1080, and first resolution form is pattern 1, then the video image of first resolution form carries out image resolution ratio conversion Downscaler process, resolution format is converted to pattern 4.
In the embodiment of the present invention, due to before being converted to the second resolution form mated with display screen, resolution format is unified, therefore the resolution of the video signal after image procossing VDP/DDP module, display processing module, display screen is stable, does not result in blank screen problem caused after changing in playing process because of resolution.

Then, to the N+P frame video image being subsequently converted to first resolution form, after the nth frame video image after the conversion that will preserve in cache module exports, when the frame number of the video image namely preserved in cache module is less than P, N+P frame video image is saved in cache module；Such as, N is initially 1, P=3, preserves 3 frame video images in cache module, after the 1st frame video image output then preserved in cache module, is saved in cache module by the 4th frame video image；N adds 1, repeats above-mentioned steps, until all being exported by all video images.
Wherein, P comprehensively can determine according to the capacity of the buffer time that real image commences play out and cache module, owing to the conversion time of different resolution form is different, and the image of cache module≤P frame.
The purpose being saved in cache module is to ensure that inside cache module has a few frame video image to exist all the time, although this is due to less for the time difference required for different resolution formats when first resolution form is changed, but the picture frame after treated some, still has regular hour difference on different resolution；Therefore start to process frame by frame from N+P frame, and the output situation of the video image according to cache module storage below, storage is in cache module, as long as namely less than P frame video image in cache module, just the N+P frame newly processed is put in cache module, it is ensured that cache module has all the time eventually 1 arrive P frame video image.
The Main Function of cache module is that the video image after unified resolution format conversion is carried out buffer memory, can store P frame video image simultaneously, and real-time by video image with certain speed at the uniform velocity exporting to each follow-up functional processing module one by one.
In the present embodiment, owing to cache module saving the video image after a number of conversion, even if the follow-up time carrying out format conversion processing is longer, first the video image in cache module can also be exported, without inserting blank screen signal, compared with prior art, do not result in playing process changes because of resolution after caused blank screen problem.
Further, it is before second resolution form by the first resolution format conversion of video image, also includes:
The every frame video image at the uniform velocity exported from cache module is carried out image quality process.
Specifically, the every frame video image at the uniform velocity exported in cache module is sequentially carried out the image quality effect process such as Color control (ColorManager), noise reduction, definition, supersolution picture, gamma Gamma；As it is shown on figure 3, VDP/DDP is image processing module, for the video image of cache module output is carried out the image quality effect process such as ColorManager, noise reduction, definition, supersolution picture, Gamma；
