Encoder, decoder, encoding method and decoding method for color moving image and method of transferring bitstream of color moving image |
摘要 |
A luminance signal of each of first pictures to be used as reference pictures in inter-picture predictive encoding is encoded into a progressive moving-image signal whereas color-difference signals of each first picture are encoded into first moving-image signals having scanning lines decimated to one-half of scanning lines of the progressive moving-image signal. On the contrary, a luminance signal and also color-difference signals of second pictures not to be used as reference pictures in inter-picture predictive encoding are encoded into second moving-image signals having scanning lines decimated to one-half of the scanning lines of the progressive moving-image signal. The progressive moving-image signal and the first and second moving-image signals are combined into a color moving-image bitstream.
