Interest statement member 121 is made of 4 the second dummy units 1210,120 quantity of the second label in each information unit 121 be one or
Two, the type of information unit 121 is increased in this way, so as to express more information contents.For coding shown in Fig. 4
Region 1, encoding identification device identify the quantity of the second label 120 in each information unit 121 and the second virtual list at place
Member 1210, obtain the corresponding value information of each information unit 121, again as shown in fig. 6, Fig. 6 A- Fig. 6 J respectively indicate one or
Two the second labels 120 four the second dummy units of difference 1210 the case where, the value information of expression is respectively 0000,0001,
0010,0011,0100,0101,0111,1000,1001,1011,1100, then the value information of 12 information units 121 is carried out
Splicing, to obtain the information content of the coding region 1.
In a preferred embodiment, in order to indicated in the case where 1 size of coding region is constant more location informations and
Content information can increase the second dummy unit 1210 in 111 first dummy unit 1110 of positioning unit and information unit 121
Quantity, for example set 6 for the first dummy unit 1110 of positioning unit 111, second in information unit 121 is virtual single
The quantity of member 1210 is set as 6, and 120 quantity of the second label in each information unit 121 is 1,2 or 3, in this way may be used
To increase arrangement mode of first label 110 in the positioning unit 111, and increase by the second label 120 in the information
Arrangement mode in unit 121, to indicate more location informations and content letter in the case where 1 size of coding region is constant
Breath.
