    • A method, device and system for signal encoding and decoding, the method comprising: encoding a core layer signal to obtain a core layer signal code; selecting an enhancement sample point that requires enhancement layer signal encoding according to the core layer signal code and the number of bits that can be used by an enhancement layer; obtaining an enhancement layer signal code of the enhancement sample point; and outputting a bit stream, where the bit stream includes the core layer signal code and the enhancement layer signal code. In embodiments of the present invention, according to the number of bits that can be used by the enhancement layer, the enhancement sample point that requires enhancement layer signal encoding is selected; the enhancement layer signal of the selected enhancement sample point is encoded and decoded; when no sufficient bits are available for the enhancement layer, the enhancement quality of the core layer can be improved.
    • 一种用于信号编码和解码的方法,装置和系统,所述方法包括:对核心层信号进行编码以获得核心层信号码; 选择需要根据核心层信号码的增强层信号编码和增强层可以使用的位数的增强采样点; 获得增强采样点的增强层信号码; 并输出比特流,其中比特流包括核心层信号码和增强层信号码。 在本发明的实施例中,根据增强层可以使用的比特数,选择需要增强层信号编码的增强采样点; 所选择的增强采样点的增强层信号被编码和解码; 当没有足够的比特可用于增强层时,可以提高核心层的增强质量。
