    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.

    摘要： There are provided selective prediction encoding and decoding methods and selective prediction encoding and decoding devices. The selective prediction encoding device selects and performs one of an AC/DC prediction encoding method and an intra prediction encoding method which corresponds to the smaller of code amount from AC/DC prediction and an amount of AVC intra coding, records information indicating the selected encoding method in a header of a bit stream, and transmits the bit stream to the selective prediction decoding device. The selective prediction decoding device decodes the transmitted bit stream by the use of a decoding process corresponding to the information recorded in the header. Accordingly, it is possible to improve compression ratio and image quality by using the selective prediction encoding and decoding methods.
