Currently, showing picture for more pictures, decoding channels and picture code stream channel are corresponded, than if any N number of code stream
Channel, that is, when showing N picture, N number of decoding channels can be corresponded to.If it is logical that the quantity in picture code stream channel is greater than decoding
The quantity in road can then be such that multiple picture code stream informations decode in a decoding channels, thus the number of the decoding channels of creation
Amount is less than the quantity for needing picture to be shown.
For example, needing to show 16 pictures, 10 decoding channels can be created, 16 picture code stream informations are input to 10
In a decoding channels, display pretreatment carried out to the image information of output, then to by show pretreated image information into
Row display, the display of more pictures is realized with this.
The application scenarios of description of the embodiment of the present invention are the technical solutions in order to more clearly illustrate the embodiment of the present invention,
The restriction for technical solution provided in an embodiment of the present invention is not constituted, those of ordinary skill in the art are it is found that with newly answering
With the appearance of scene, technical solution provided in an embodiment of the present invention is equally applicable for similar technical problem.
For above-mentioned application scenarios, the embodiment of the present invention provides a kind of method that picture is shown, as shown in Fig. 2, this method
Specifically comprise the following steps:
S200, N number of picture code stream information that N number of picture code stream channel exports is input in M decoding process channel,
Middle N and M is positive integer, and N is greater than M；
S201, the first image information for exporting decoding process channel carry out display pretreatment, obtain at least one second
Image information；
S202, it second image information of at least one obtained is input to hardware display channel shows.
In the embodiment of the present invention, N number of picture code stream information that N number of picture code stream channel exports is input to M solution first
Code treatment channel in, wherein N and M be positive integer, and N be greater than M, the first image information for then exporting decoding process channel into
Row display pretreatment, obtains at least one second image information, is finally input at least one obtained second image information
Hardware display channel is shown, to realize the display of more pictures.Since the quantity M in decoding process channel is more logical than picture code stream
The quantity N in road is few, so without creation and the same decoding process channel of picture code stream number of channels, thus when decoding capability foot
When enough but creating N number of decoding channels low memory, the demand that more pictures are shown can be realized.
It should be noted that finally being shown after the picture code stream information in N number of picture code stream channel is by some processing
Channel shows N picture.
In the embodiment of the present invention, N number of picture code stream information that N number of picture code stream channel exports is input at M decoding
It manages in channel.
Wherein, the quantity M in decoding process channel, can preset, and the pictorial information that can also be grabbed according to front end is true
It is fixed；
The creation in decoding process channel, can the creation when front end grabs pictorial information, can also be grabbed in front end
After pictorial information, pictorial information is input in picture code stream channel, then the picture code stream information in picture code stream channel is defeated
It is created when out.
The quantity M and creation decoding process channel that determine decoding process channel are illustrated below.
Mode one, decoding process channel quantity M preset, decoding process channel is created in front end capturing pictures information
It builds.
For example the quantity M in decoding process channel is set in advance as 3, front end grabs 10 pictorial informations, is grabbed according to front end
3 pictorial informations in 10 pictorial informations taken create 3 decoding process channels, distribute when creating decoding process channel interior
It deposits and is determined by the resolution ratio, pictorial information quantity and fixed coefficient of the picture in pictorial information, if photo resolution is
704*576, pictorial information quantity are 10, and fixed coefficient 1.5 then creates memory when decoding process channel, 704*576*10*
1.5=6082560 byte of memory.
Mode two, decoding process channel quantity M preset, decoding process channel grabs pictorial information in front end
Afterwards, it is created when pictorial information being input in picture code stream channel, then the picture code stream information in picture code stream channel being exported.
For example the quantity M in decoding process channel is set in advance as 3, after front end grabs 10 pictorial informations, and 10 are schemed
Piece information input is into 10 picture code stream channels, when picture code stream channel exports 10 pictorial informations, according to 10 pictures
The photo resolution of 3 picture code stream informations in code stream information creates 3 decoding process channels.This 3 picture code stream informations
It can be randomly selected, can also be selected according to the time sequencing of output, such as according to the 3 picture code stream informations exported at first
Photo resolution creates 3 decoding process channels.
Mode three, the pictorial information that the quantity M in decoding process channel is grabbed according to front end are determining, and decoding process channel is preceding
It is created when holding capturing pictures information.
For example, the pictorial information of front end crawl is 10 pictorial informations, after front end grabs 10 pictorial informations, according to solution
The memory and 10 pictorial informations of code device, determination needs to create several decoding channels, if 100 are saved as in decoder, according to
Resolution ratio, frame number and the fixed coefficient of 10 pictorial informations determine the corresponding decoding process channel needs of 10 pictorial informations
20,50,20,40,30,41,51,43,50,40 are saved as in distribution, due to saving as 100 in decoder, so 3 can only be created
Decoding process channel, it is determined that behind 3 decoding process channels of creation, according to point of 3 pictorial informations in 10 pictorial informations
Resolution, frame number and fixed coefficient create 3 decoding process channels.
Mode four, the pictorial information that the quantity M in decoding process channel is grabbed according to front end are determining, and decoding process channel is preceding
After end grabs pictorial information, pictorial information is input in picture code stream channel, then by the picture code in picture code stream channel
Stream information creates when exporting.
For example, the pictorial information of front end crawl is 10 pictorial informations, after front end grabs 10 pictorial informations, according to solution
The memory and 10 pictorial informations of code device, determination needs to create several decoding channels, if 100 are saved as in decoder, according to
Resolution ratio, frame number and the fixed coefficient of 10 pictorial informations determine the corresponding decoding process channel needs of 10 pictorial informations
20,50,20,40,30,41,51,43,50,40 are saved as in distribution, due to saving as 100 in decoder, so 3 can only be created
Decoding process channel, it is determined that behind 3 decoding process channels of creation, grab 10 pictorial informations are input to 10 by front end
In picture code stream channel, when picture code stream channel exports 10 pictorial informations, according to 3 figures in 10 picture code stream informations
Piece code stream information creates 3 decoding process channels.
After M decoding process channel creation, N number of picture code stream information in N number of picture code stream channel is input to M solution
Code treatment channel in when, initially set up the mapping relations of N number of picture code stream information and M decoding process channel, then, for times
It anticipates a picture code stream channel, the picture code stream information exported in the picture code stream channel is input to and is reflected with picture code stream channel
In the decoding process channel penetrated.
In an implementation, the mapping relations of N number of picture code stream information and M decoding process channel are established, remainder can be used
Mapping method, m=k%M, wherein m is m-th of decoding process channel being mapped to, and k is k-th of picture code stream channel, and M is
The number in decoding process channel.
For example, there is 3 decoding process channels, decoding process channel 1, decoding process channel 2 and decoding treatment channel 3, root
According to the mapping algorithm of remainder, 4%3=1, so the 4th picture code stream channel map is into first decoding process channel.
According to the mapping relations of N number of the picture code stream information and M decoding process channel of foundation, for any one picture
Picture code stream information in the picture code stream channel is input to decoding process corresponding with the picture code stream channel by code stream channel
It is decoded in channel.
Wherein, decoding process channel can be decoding channels, be also possible to decoding channels and treatment channel.
When decoding process channel is decoding channels, it is logical that the picture code stream information of picture code stream channel output is input to decoding
Behind road, the picture code stream information is decoded by the decoding channels, is believed decoded pictorial information as the first image
Breath；
As shown in figure 3, being the structural schematic diagram that decoding process of embodiment of the present invention channel is decoding channels.In Fig. 3, there is N
A picture code stream channel, M decoding channels, N number of picture code stream channel is by channel map, by N number of picture code stream channel map
To M decoding channels.
When decoding process channel is decoding channels and treatment channel, the picture code stream information of picture code stream channel output is defeated
Enter to after decoding channels, the picture code stream information is decoded by the decoding channels, then decoded image information is defeated
Enter into treatment channel and carry out image procossing, using the image information obtained after processing as the first image information.
As shown in figure 4, being the structural schematic diagram that decoding process of embodiment of the present invention channel is decoding channels and treatment channel.
In Fig. 4, there is N number of picture code stream channel, M decoding channels, N number of picture code stream channel is by channel map, by N number of picture code stream
Channel map to M decoding channels, M decoding channels correspond to M treatment channel.
It should be noted that treatment channel is to carry out image effect processing to decoded image information, in picture code
Stream information obtained image information after decoding can carry out the processing of image effect by treatment channel, can also be without
It crosses treatment channel and carries out image effect processing.Specifically whether need to carry out image effect processing by treatment channel, according to reality
It needs to be determined that the embodiment of the present invention is without limitation.
When the picture code stream information of picture code stream channel output is input to the decoding process channel of picture code stream channel map
When middle, if the resolution ratio of picture is greater than in the decoded picture code stream information of the last decoding channels in the picture code stream information
The resolution ratio of picture then destroys the decoding channels, redefines new decoding channels further according to the picture code stream information, and pass through
New decoding channels are decoded processing to the picture code stream information.
For example, there is 3 decoding channels, decoding channels 1, decoding channels 2, decoding channels 3, the last time passes through decoding channels 1
Decoded photo resolution is 720*576, this, should by picture code stream channel map to decoding channels 1 after channel map
Photo resolution in picture code stream channel is 1920*1080, since this is differentiated by the picture that decoding channels 1 are decoded
Rate is greater than the last photo resolution being decoded by the decoding channels, so the decoding channels are destroyed, according to this need
The resolution ratio of decoded picture is wanted to create new decoding channels.
If the resolution ratio of picture is less than or equal to the decoded picture code of the last decoding channels in the picture code stream information
The resolution ratio of picture in stream information, the decoding channels that then be used directly are decoded processing to the picture code stream information.
For the same decoding channels, when using the mapping method of remainder, if mapping to the decoding channels every time
The corresponding photo resolution in picture code stream channel is different, then can destroy the decoding channels every time, believes further according to the picture code stream
Breath creates new decoding channels, and frequent destruction and creation decoding channels can generate many fragments.In order to avoid fragment problems, originally
Inventive embodiments can also using by the corresponding picture code stream channel map of the identical picture code stream information of resolution ratio to same
The mapping method of decoding channels.
Than if any 10 picture code stream channels, picture code stream channel 1, picture code stream channel 2, picture code stream channel 3, picture
Code stream channel 4, picture code stream channel 5, picture code stream channel 6, picture code stream channel 7, picture code stream channel 8, picture code stream are logical
, there are 3 decoding channels, decoding channels 1, decoding channels 2 and decoding channels 3 in road 9 and picture code stream channel 10, if picture code stream
The photo resolution of picture code stream information in channel 1, the photo resolution of picture code stream information in picture code stream channel 2 with
And the photo resolution of the picture code stream information in picture code stream channel 3 is identical, then leads to picture code stream channel 1, picture code stream
Road 2 and picture code stream channel 3 map to the same decoding channels, for example map to decoding channels 1.
Picture code stream information be input to decoding process channel be decoded or be decoded and image procossing after, from decoding place
Reason channel in export, obtain the first image information, which be subjected to display pretreatment, obtain at least one second
At least one second image information is finally input to hardware display channel and shown by image information.
The first image information that decoding process channel is exported carries out display pretreatment, obtains at least one second image letter
Breath, then at least one obtained second image information is input to hardware display channel and is shown, there are two types of implementations.
The implementation that more pictures are shown, which is illustrated, to be realized to both separately below.
After mode one, timesharing obtain N number of first image information of M decoding process channel output, N number of first image is believed
Breath zooms in and out processing, obtains N number of second image information, and obtained N number of second image information is input to N number of hardware and is shown and is led to
