Abstract:
1. A video decoding system having a first mode of decoding an encoded video data stream and generating decoded video data to a memory, and having a second mode of generating a virtual picture between a first picture and a second picture to the memory, the video decoding system comprising a Variable Length Decoder (VLD) module, an Inverse Quantization (IQ) module, an Inverse Discrete Cosine Transformer (IDCT) module, a Motion Compensator (MC) module, a Block Reconstruction (BR) module, and a parameter generating module, wherein in the first mode, wherein in the second mode, the parameter generating module generates a virtual picture parameter to the MC module so as to make the BR module generate the virtual picture between the first picture and the second picture to the memory, wherein the virtual picture parameter is not generated by decoding the encoded video data stream.
