  • Hybrid-resolution encoding and decoding method and a video apparatus using the same
    Patent number: 10097821
    Abstract: The present invention provides a hybrid-resolution encoding and decoding method. The method includes performing full-resolution standard coding on an I frame that adopts only intra-frame coding in a video frame sequence, and performing frame reconstruction to obtain a reconstructed frame of the I frame; performing down-sampling on the reconstructed frame of the I frame to obtain a first sampling image of the reconstructed frame of the I frame; performing down-sampling on a non-I frame in the video frame sequence to obtain a second sampling image of the non-I frame; performing standard coding on the second sampling image of the non-I frame by using the first sampling image of the reconstructed frame of the I frame that corresponds to the non-I frame as a reference frame; and sending a video code stream that includes the full-resolution standard coded I frame and the standard coded non-I frame.
