摘要：
The method involves performing intra frame coding of a non-compressed picture frame to produce one compresses picture frame which is then decoded to produce one reference picture frame. Inter frame coding is performed between the non-compresses picture frame and another reference picture frame to produce another compressed picture frame (615). The frame (615) is decoded to produce a third reference picture frame. An independent claim is also included for a stepwise image quality complementary type coding apparatus.
