Description
Technical field
The present invention relates to coding and decoding video fields, in particular to a kind of odd encoder point shuffling for Video coding
Flowing water method and device thereof.
Background technique
Electronic information technology develops rapidly at present, and video is very widely used, with imaging sensor and integrated circuit
The development of technology, video capture are also started from profession to public quickly diffusion, including network video, Web TV, cabled digital
TV, cell-phone camera etc..In the treatment process to these video datas, coding and decoding video is indispensable important step.
At present the video encoding and decoding standard of mainstream be MPEG4-part2 and H.264 and formulation in 2013 complete H.265, these mark
Standard is all based on the hybrid encoding frame of block.
It is known that the calculation amount of Video coding is very big, common processor due to computing capability and power consumption factor, and
Video coding is not suitable for.Since Video coding is block-based hybrid coding, there are a large amount of simple duplicate operations, therefore
More it is suitble to DSP (Digital Signal Processor, digital signal processor) and ASIC (Application
Specific Integrated Circuit, specific integrated circuit) parallel execution.
In Video coding, image is typically split into continuous Video coding basic unit, such as in MPEG4-part2 and
H.264 in video encoding standard and before usually using macro block as coding basic unit, in H.265 video encoding standard with
CU (Coding Unit) is coding basic unit.There is intra prediction, inter-prediction, movement in advance in each coding basic unit
Survey, transformation, quantization, inverse quantization, inverse transformation, entropy coding, the submodules such as deblocking filtering exist in execution between the submodule of part
Dependence needs sequence to execute.
For Video coding, flowing water technology is mostly used at present.The flowing water technological borrowing of the processor stream of plant produced
One work is divided into multiple continuous processes by waterline thought, and each section of process for being only responsible for oneself passes to next after completing
A process, such as then there are multiple products to be processed in different processes in same timeslice.Stream treatment is that handle will be located
The functional module of reason is divided into sub-function module can continuously performing and that elapsed time is unanimous on the whole, to farthest utilize
Hardware resource.
The flowing water skill of Video coding is carried out under introducing by taking current H.264 video encoding and decoding standard as an example currently based on ASIC
Art.Since macroblock coding has pattern discrimination module (inter-frame mode differentiates and frame mode differentiates), motion prediction module, converted quantity
Change module (comprising intra prediction, transformation, quantization, inverse quantization, inverse transform block and completing coding and rebuilding), entropy code module,
And deblocking filtering module, the specific coding process of macroblock coding are as shown in Figure 1, wherein the module executed parallel indicates two
A module can be in no particular order in operation processing.
As it can be seen that macroblock coding is typically divided into 4 sequential steps as shown in Figure 1, refering to what is shown in Fig. 2, if not using
Flowing water technology, then only one module is working in piece at the same time, so that one macro block of coding needs 4 unit time.
On the contrary, if 4 modules are all working in same timeslice using flowing water technology, so that one macro block of coding only needs
1 unit time is wanted, so as to improve macroblock coding efficiency.Such as patent document CN200810062856.6 discloses one
It kind is used for the mixed production line apparatus of Video coding, in technical solution, in piece at the same time, prefetches data device, mode
Selector, reconstruction loop device and entropy coder handle the data of four different macro blocks, and the flowing water behaviour of macroblock coding is realized with this
Make.
Therefore, for the Video coding currently based on ASIC, mostly use the mode of flowing water to improve coding rate and effect greatly
Rate.
In Video coding, video compress mainly utilizes the spatial correlation, relativity of time domain and entropy coding of image, usually
Will cause current macro, there are dependences to encoded adjacent macroblocks, and for example intra prediction need to use the reconstruction figure of adjacent macroblocks
Picture, predicted motion vector need to be calculated acquisition by adjacent macroblocks.Inventors have found that due between current macro and encoded macro block
There are dependences, so that information needed for current macro needs to rely on, whether previous macro block is completed, and is affected so macro
The flowing water speed of block coding, there are the flowing water waiting problems of macroblock coding.
In order to solve flowing water waiting problem caused by macro block relies on, current solution mostly uses replacing for approximate simulation
For method, for example the differentiation of macro block progress frame mode, which needs to use adjacent macroblocks, can be adopted with reconstruction image in order to avoid relying on
It is usually replaced with the original image of surrounding macro blocks.It can be seen that solving the flowing water waiting problem because caused by relying on encoding block at present
The problem of mostly using approximate calculation greatly to realize, waiting when really generating code stream according still further to standard implementation, bring in this way be exactly
The accuracy of pattern discrimination and motion search influences actual compression efficiency.

In order to solve flowing water waiting problem caused by macro block existing in the prior art relies on, improve what coding mode differentiated

The rest may be inferred, in turn executes coding until the volume to i-th of image coding basic unit of m-th of subgraph of extraction
Each subgraph in code block container, which encodes, to be completed；
Wherein, the 1 < m, 1 < i.
4. a kind of odd encoder point shuffling water plant for Video coding characterized by comprising
Division module, for divide an image at least two can parallel encoding subgraph；
Grouping module, at least two encoding block containers will to be passed to after subgraph grouping；
Shuffling flowing water module is executed for the flowing water coded sequence to each subgraph in present encoding block container according to configuration
Image encodes the coding of basic unit, and after the subgraph coded treatment for completing the current encoding block container, executes under
The subgraph coded treatment of one encoding block container, until completing the subgraph coded treatment of all encoding block containers, wherein described
Flowing water coded sequence is configured as cyclically successively extracting a uncoded image coding basic unit from each subgraph,
Image is executed according to the flowing water coded sequence of configuration to each subgraph in each encoding block container and encodes basic unit
The strategy of coding be:
In turn the 1st image of the 1st image coding basic unit of the 1st subgraph of extraction, the 2nd subgraph is compiled
Code basic unit, the 1st image coding basic unit of the 3rd subgraph ... the 1st image of m-th of subgraph encodes base
This unit executes coding；
In turn the 2nd image of the 2nd image coding basic unit of the 1st subgraph of extraction, the 2nd subgraph is compiled
Code basic unit, 2 images coding basic unit of the 3rd subgraph ... the 2nd image coding of m-th of subgraph is basic
Unit executes coding；
The rest may be inferred, in turn executes coding until the volume to i-th of image coding basic unit of m-th of subgraph of extraction
Each subgraph in code block container, which encodes, to be completed；
Wherein, the 1 < m, 1 < i.
