    摘要： A video unified codec device and corresponding video method. The unified codec device includes parsing and decoding functional units (PD FUs) extracting and grouping context information, control signals, and data in bit streams inputted according to different syntax data per codec, macro-block-based functional units (MB-based FUs) comprising block-based process units of each codec, for decoding data outputted from PD FUs, and a global control unit (GCU) for controlling MB-based FUs grouped after corresponding control signals and context information received from PD FUs to each codec and processing.
