" * " expression multiplication sign in the embodiment of the present invention.
Fig. 1 is the schematic flow sheet of the binaryzation code processing method embodiment one of syntactic information provided by the invention, and as shown in Figure 1, the method comprises:
S101, the initial binaryzation coding strategy of employing carry out the first binaryzation to each syntactic element in the syntactic information set, obtain the first binaryzation character string corresponding to each syntactic element (being called the bin string in the present invention).The bin string that each syntactic element is corresponding is entirely not identical.Wherein, binaryzation can adopt various dual codes, such as: Huffman (Huffman) code, monobasic code, monobasic truncated code, index Columbus code and configurable variable length code etc., or the combination of different dual codes.
Initial binaryzation coding strategy can adopt prior art setting, also can obtain according to experiment statistics test data experience.
In video coding process, understand constantly, repeatedly each syntactic element in above-mentioned syntactic information carried out binaryzation.
S102, according to above-mentioned initial binaryzation coding strategy, determine whether to carry out the coding mode distribution statistics and upgrade the binaryzation coding strategy.If, carry out S103, if not, carry out S104.
Binaryzation coding strategy after S103, employing are upgraded carries out the second binaryzation to each syntactic element in above-mentioned syntactic information set, obtains the second binaryzation character string corresponding to each syntactic element.Equally, binaryzation can adopt various dual codes, such as: Huffman code, monobasic code, monobasic truncated code, index Columbus code and configurable variable length code etc., or the combination of different dual codes.

Fig. 2 is the schematic flow sheet of the binaryzation code processing method embodiment two of syntactic information provided by the invention, and the concrete steps of above-mentioned execution coding mode distribution statistics and renewal binaryzation coding strategy are:
S201, the required total bit (bit) of each syntactic element binaryzation coding strategy in above-mentioned grammer set number is carried out distribution statistics, obtain the distribution statistics result.Wherein, total bit number is the bit number size that is used for each syntactic element of sign grammer information aggregate in the binaryzation process.
S202, according to the distribution statistics result, formulate to upgrade the binaryzation coding strategy.
Be specially, adopt the required total bit number of binaryzation coding strategy of each syntactic element in this syntactic information set to minimize, formulate and upgrade the binaryzation coding strategy.Illustrate, for example: a grammer set T={a
i, i=0,1 ... M, M are natural number, the number of expression syntactic information set T institute value, suppose M=6, and the number of times of each syntactic element of binaryzation is { 4,3,3,1,1,2}, adopt total bit number to minimize corresponding binaryzation coding strategy and carry out binaryzation, and in its syntactic information set, the bit number of each syntactic element size is { 00,01,10,1110,1111,110}, required total bit number is 4*2+2*3+2*3+1*4+1*4+2*3=34.And if employing fixed length binaryzation strategy (3bit) carries out binaryzation, in its syntactic information set, the bit number of each syntactic element size is { 000,001,010,011,100,101}, required total bit number is 3* (4+3+3+1+1+2)=42, can find out and adopt fixed length binaryzation mode can cause the waste of position.
Need to prove, above-mentioned execution coding mode distribution statistics and renewal binaryzation coding strategy can be execution cycle or aperiodic coding mode distribution statistics and upgrade the binaryzation coding strategy.
Further, the initial binaryzation coding strategy of above-mentioned basis determines whether to carry out the coding mode distribution statistics and upgrades the binaryzation coding strategy, be specially: judge that whether initial binaryzation coding strategy is based on the binaryzation coding strategy of above-mentioned coding mode distribution statistics and renewal binaryzation coding strategy, judges namely whether initial binaryzation coding strategy is based on binaryzation coding strategy embodiment illustrated in fig. 2; If, can select to carry out or do not carry out above-mentioned coding mode distribution statistics and upgrade the binaryzation coding strategy, do not carry out if select, adopt initial binaryzation coding strategy to carry out binaryzation to each syntactic element in the syntactic information set with regard to continuing, select to carry out, that just adopts the binaryzation coding strategy after upgrading to carry out binaryzation to each syntactic element in the syntactic information set after carrying out; If not, carry out the binaryzation coding strategy of above-mentioned coding mode distribution statistics and renewal binaryzation coding strategy.In specific implementation process, can determine whether to carry out the coding mode distribution statistics according to the complexity situation of coding and upgrade the binaryzation coding strategy, generally, if when the complexity of coding is low, can select not carry out.

Table 2
| Syntactic element | The bin string |
| A | 1 |
| B | 01 |
| C | 001 |
| D | 0001 |
| E | 00001 |
| F | 000001 |
| G | 0000001 |
Illustrate again above-described embodiment, suppose that this syntactic information set comprises 7 syntactic elements { A, B, C, D, E, F, G}, its initial binaryzation coding strategy is based on the coding mode distribution statistics and upgrades the binaryzation coding strategy of binaryzation coding strategy, namely this initial binaryzation coding strategy just was based on the distribution statistics result originally, was to be minimized and decided by the required total bit number of binaryzation coding strategy that identifies each syntactic element in the grammer information aggregate.It is as shown in table 3,
Table 3
| Syntactic element | The bin string |
| A | 00 |
| B | 01 |
| C | 10 |
| D | 110 |
| E | 1110 |
| F | 11110 |
| G | 11111 |
In this case, can select to carry out or do not carry out the coding mode distribution statistics and upgrade the binaryzation coding strategy,, if select not carry out, continuing to adopt initial binaryzation coding strategy to carry out binaryzation to each syntactic element in the syntactic information set.If select to carry out, carry out embodiment illustrated in fig. 2ly, obtain the binaryzation coding strategy after renewal, then adopt the binaryzation coding strategy after upgrading to carry out binaryzation to each syntactic element in the syntactic information set, obtains new bin and go here and there, as shown in table 4,
Table 4
| Syntactic element | The bin string |
| A | 1 |
| B | 01 |
| C | 0000 |
| D | 0001 |
| E | 0010 |
| F | 00110 |
| G | 00111 |
In the present embodiment, determine whether to carry out the coding mode distribution statistics and upgrade the binaryzation coding strategy according to initial binaryzation coding strategy, and then adopt the binaryzation coding strategy after upgrading or show the binaryzation coding strategy and carry out binaryzation, can select neatly the binaryzation coding strategy according to actual conditions according to having realized, and minimize according to the required total bit number of binaryzation coding strategy of each syntactic element in sign grammer information aggregate the binaryzation strategy that decides renewal, can eliminate well information redundancy.
