    摘要: A code stream conversion system and method, a code stream identifying unit and a solution determining unit are provided. The code stream conversion method includes: receiving an original code stream format obtained by parsing an original code stream; and determining a transcoding solution according to a target code stream format and the original code stream format, and using the original code stream format to decode the original code stream and using the target code stream format to encode a decoded code stream according to the transcoding solution, thus completing code stream conversion, and obtaining a target code stream corresponding to the target code stream format. Through the code stream conversion system and method, the original code stream is parsed and the transcoding solution is determined, thus achieving mutual conversion between a three-dimensional video code stream and a planar video code stream.

    摘要: The invention provides a method of efficiently producing branched, cyclic glycerol-based polyols with a co-product as anti-biodegrading agent from inexpensive readily available glycerol monomer. The method involves polymerizing glycerol or glycerol with at least another monomer to multiple other monomers in the presence of particular amount of a strong base as the catalyst under a particular distillation environment. The polyol produced by the inventive method is beneficial of reducing scales in Bayer liquid for aluminum production process and improving brightness of coated paper substrates without greening effect.
