Embodiment 1
[0030] Embodiment 1: Binarization of the Level absolute value of the transformation coefficient
[0031] attached figure 2 It shows the binarized encoding device of the present invention, including the sub-field division device and the code synthesis device.
[0032] The currently to-be-encoded data (denoted as data_value) is input to the sub-field division device. The sub-field division device divides the value domain of the data to be encoded into m=2 sub-fields, the corresponding sub-field base values are respectively bv0=1 and bv1=15, and the sub-field flag bit strings are respectively b0='0' and b1=' 1', that is, if the data to be encoded is greater than 0 and less than 15 at the same time, the subfield division device outputs the subfield flag bit string '0' and the relative value data_value-1 of the subfield; if the data to be encoded is greater than or equal to 15, the subfield division device outputs the subfield Field flag bit string '1' and subfield relative va...
Embodiment 2
[0035] Embodiment 2: Binarization of the absolute value of the motion vector residual component
[0036] attached figure 2 It shows the binarized encoding device of the present invention, including the sub-field division device and the code synthesis device.
[0037] The currently to-be-encoded data (denoted as data_value) is input to the sub-field division device. The subfield division device divides the data value domain to be encoded into m=2 subfields, the corresponding subfield base values are respectively bv0=0 and bv1=9, and the subfield flag bit strings are respectively b0='0' and b1=' 1', that is, if the data to be encoded is greater than or equal to 0 and less than 9 at the same time, the subfield division device outputs the subfield flag bit string '0' and the relative value data_value of the subfield; if the data to be encoded is greater than or equal to 9, the subfield division device outputs the subfield Flag bit string '1' and subfield relative value data_v...
