    • The invention includes: a bitstream updating output unit configured to receive a bitstream and update a syntax element located at a beginning of the bitstream according to a code length thereof and outputs the syntax element; a bitstream decoding unit configured to decode, in response to a decode request, a variable-length code of the syntax element outputted from the bitstream updating output unit; a zerosLeft updating unit configured to update zerosLeft based on a specific syntax element decoded by the bitstream decoding unit; a run_before remaining number updating unit configured to update a run_before remaining number based on a specific syntax element decoded by the bitstream decoding unit; and a syntax selection unit configured to select a syntax element to be decoded by the bitstream decoding unit. Thus, multiple zero run_before syntaxes and one non-zero run_before syntax, or multiple zero run_before syntaxes are decoded all at once.
    • 本发明包括:比特流更新输出单元,被配置为根据其比特流的码长来接收比特流并更新位于比特流的开头的语法元素,并输出语法元素; 比特流解码单元,被配置为响应于解码请求解码从比特流更新输出单元输出的语法元素的可变长度代码; zerosLeft更新单元,被配置为基于由比特流解码单元解码的特定语法元素来更新zerosLeft; run_before剩余号更新单元,被配置为基于由比特流解码单元解码的特定语法元素来更新run_before剩余号码; 以及语法选择单元,被配置为选择要由比特流解码单元解码的语法元素。 因此,多个零run_before语法和一个非零run_before语法,或多个零run_before语法被一次解码。
