Abstract

A decoder for decoding a plurality of digital video data (80) is described. Figure 1A shows a DV video decoder (100) for decoding digital video data which is formatted according to the DV standard. The DV video decoder has a Very-Long Instruction Word (VLIW) processor and a variable length decoding unit. The VLIW processor includes a preparser unit (90) for recovering a decoding order of the digital video data so that the variable length decoding unit can process the digital video data. In addition, the VLIW processor includes a decompression unit for decompressing the digital video data which has been decoded by the variable length decoding unit for display (120).
