Description
Technical field
The present invention relates to coding and decoding video field, in particular to a kind of point of the odd encoder for Video coding shuffling flowing water method and device thereof.
Background technology
Current electronic information technology develop rapidly, the application of video widely, along with the development of imageing sensor and integrated circuit technique, video capture also by specialty to popular rapid diffusion, comprise Internet video, Web TV, cable digital TV, cell-phone camera etc.To in the processing procedure of these video datas, coding and decoding video is indispensable important step.The video encoding and decoding standard of current main flow is MPEG4-part2 and H.264, and H.265 2013 formulated, and these standards are all block-based hybrid encoding frame.
Knownly, the amount of calculation of Video coding is very large, and common processor due to the factor of computing capability and power consumption, and is not suitable for Video coding.Because Video coding is block-based hybrid coding, there is a large amount of simple operation repeated, therefore comparatively DSP (DigitalSignalProcessor is applicable to, digital signal processor) and the executed in parallel of ASIC (ApplicationSpecificIntegratedCircuit, application-specific integrated circuit (ASIC)).
In Video coding, image is divided into continuous print Video coding elementary cell usually, as MPEG4-part2 and H.264 and before video encoding standard in usually using macro block as coding elementary cell, in H.265 video encoding standard with CU (CodingUnit) for coding elementary cell.All there is infra-frame prediction, inter prediction, motion prediction, conversion, quantification, inverse quantization, inverse transformation, entropy code, the submodules such as block elimination filtering in each coding elementary cell, between parton module execution on Existence dependency relationship, needs order perform.
For Video coding, mostly adopt flowing water technology at present.The flowing water technological borrowing of the processor streamline thought of plant produced, a job is divided into multiple continuous print operation, each section is only responsible for oneself operation, passes to next operation after completing, such as, then have multiple product in sheet at one time and process in different operations.Stream treatment namely functional module to be processed be divided into can perform continuously and the sub-function module that elapsed time is unanimous on the whole, thus at utmost utilization of hardware resources.
For flowing water technology of carrying out Video coding based on ASIC current under current H.264 video encoding and decoding standard introduction.Because macroblock coding has pattern discrimination module (inter-frame mode differentiates and frame mode differentiates), motion prediction module, change quantization module (comprise infra-frame prediction, conversion, quantification, inverse quantization, inverse transform block and complete coding and rebuilding), entropy code module, and block elimination filtering module, the specific coding flow process of its macroblock coding as shown in Figure 1, wherein, the module of executed in parallel represents that two modules can be in no particular order when operational processes.
Visible, macroblock coding is divided into 4 sequential steps as shown in Figure 1 usually, shown in figure 2, if do not adopt flowing water technology, then only have a module at the same time in sheet in work, so that a coding macro block needs 4 unit interval.On the contrary, if adopt flowing water technology, then 4 modules are all in work in sheet at one time, so that a coding macro block only needs 1 unit interval, thus can improve macroblock coding efficiency.Namely such as patent documentation CN200810062856.6 discloses a kind of mixed production line apparatus for Video coding, in its technical scheme, in sheet at the same time, the data of the macro block that prefetch data device, mode selector, reconstruction loop device are different with entropy coder process four, realize the water operation of macroblock coding with this.
Therefore, for the current Video coding based on ASIC, mostly adopt the mode of flowing water to improve coding rate and efficiency.
When Video coding; video compression mainly utilizes the spatial correlation of image, relativity of time domain and entropy code; usually current macro can be caused encoded adjacent macroblocks Existence dependency relationship; for example infra-frame prediction need use the reconstruction image of adjacent macroblocks, and motion vectors need calculate acquisition by adjacent macroblocks.Inventor finds, due to Existence dependency relationship between current macro and encoded macro block, so that whether the informational needs needed for current macro depends on previous macro block and completes, and have impact on the flowing water speed of macroblock coding like this, there is the flowing water Holding Problem of macroblock coding.
The flowing water Holding Problem caused is relied in order to solve macro block, current solution mostly adopts the alternative method of approximate simulation, for example macro block carries out frame mode differentiation needs to use adjacent macroblocks to rebuild image, in order to avoid relying on, the original image of surrounding macro blocks can be adopted usually to replace.As can be seen here, the flowing water Holding Problem that current solution causes because encoding block relies on adopts approximate calculation to realize mostly, Deng real generate code stream time again according to standard implementation, the problem brought like this is exactly that the accuracy of pattern discrimination and motion search reduces, the compression efficiency that impact is actual.
