Description
Technical field
The present invention relates to contextual information access method and the system of a kind of video macro block, especially,
Relate to a kind of video macro block based on the video macro block context mechanism design towards entropy encoding/decoding
Contextual information access method and system.
Background technology
In existing video encoding and decoding standard, codec based on entropy encoding/decoding typically all can
A large amount of use prediction encoding and decoding, i.e. utilize the contextual information of adjacent macroblocks and interior macroblocks
The contextual information of sub-macroblock is as the predictive value of encoding and decoding, and along with the carrying out of encoding and decoding is continuous
Update these contextual informations.The use of these contextual informations improves encoding-decoding efficiency, with
Time too increase the complexity of codec design, such as H.264 waiting some main flows to regard
Frequency marking is accurate, and the least unit that contextual information is corresponding reaches the rank of the sub-macroblock of 4x4, the most just
Being to say, the least unit of the contextual information related in encoding-decoding process is the sub-macroblock of 4x4
Contextual information, such design makes the contextual information number related in encoding-decoding process
The hugest according to amount, the access to contextual information is complicated.
Traditional contextual information access plan is broadly divided into two classes, and a class is completely in encoding and decoding
Device chip exterior preserves these contextual informations by such as firmware and software, and in encoding and decoding
By outside firmware or software, these contextual informations are supplied to encoding and decoding before each macro block
Device, to complete encoding-decoding process, after encoding and decoding complete, firmware and software extract encoding and decoding
Result thus update and preserve new contextual information.Firmware outside this type of technical scheme needs
Contextual information is configured, although the access of context is by outside firmware or software with software
Complete to reduce the complexity of the hardware designs of codec itself, but this scheme can be beaten
The calculation process of disconnected codec, because compiling each syntactic element by codec hardware
During decoding, if needing contextual information, then must pass through outside firmware or software by hardware
The contextual information needed sends hardware to, and then hardware recycles this contextual information and solves
Code, current results is returned to software as the update content of contextual information by last hardware again,
The most complicated execution efficiency causing codec alternately between this software and hardware drops significantly
Low.
Another kind of scheme is then the context letter needed for being preserved by the hardware within codec completely
Breath, is accessed as required by codec.Contextual information is all preserved by this type of method
Inside codec hardware (in chip), accessed all required context letters by hardware completely
Breath, execution efficiency can be greatly promoted, but owing to memory space and addressing cause hardware size with multiple
Miscellaneous degree increases so that the expense of hardware designs is relatively big, and cost is high.
Summary of the invention
It is an object of the invention to solve disadvantages mentioned above of the prior art, i.e. propose a kind of video
The access method of the contextual information of macro block and system, it is possible to by contextual information is closed
The cutting of reason, thus can either try one's best during encoding and decoding and few interrupt codec hardware
