Summary:Disclosed is a management apparatus and method of 32-bit double VLD buffers capable of reading a bitstream for video decoding in a digital TV receiver in a predetermined bit data unit length. Particularly, the first VLD buffer is used for directly storing an input stream in bytes, and the second VLD buffer is used for reading and storing the bitstream from the first VLD buffer, reading the bitstream with the required bit length of the VLD by bit unit, and outputting it to the VLD. As a result, 32-bit data can be processed at once. In addition, the double VLD buffer structure also reduces the number of accesses to the VLD buffer and thus, the repetitive memory access procedure can be simplified for the VLD.
