    • PURPOSE: A transmission method, transmission apparatus, reception method, and reception apparatus for a digital broadcasting signal are provided to divide a stream into multiple layers according to the properties of the stream and independently process the layers. CONSTITUTION: A transmission method for a digital broadcasting signal comprises steps of: dividing a unit stream into multiple layers according to the properties of the stream (S104); encoding and mapping the divided layers (S105, S106); and dynamically assigning the resources of the layers based on the number of symbols of the layers (S107, S108). [Reference numerals] (AA) Start; (BB) End; (S101) Input multiple transmission streams; (S102) Multiplex in the type of a unit stream; (S103) Encode for error correction; (S104) Divide the unit stream into multiple layers; (S105) Encode the divided layers; (S106) Map the divided layers using a predetermined method; (S107) Determine the bandwidth of each layer based on the number of symbol of each layer; (S108) Assign frequency domain; (S109) Perform frequency interleaving to each layer; (S110) Perform inverse fast Fourier transform
    • 目的:提供一种用于数字广播信号的传输方法,传输装置,接收方法和接收装置,以根据流的属性将流划分成多个层,并独立地处理这些层。 构成:数字广播信号的传输方法包括以下步骤:根据流的属性将单元流划分成多个层(S104); 编码和映射划分的层(S105,S106); 并且基于层的符号的数量动态分配层的资源(S107,S108)。 (附图标记)(AA)开始; (BB)结束; (S101)输入多个传输流; (S102)单位流类型中的多路复用; (S103)编码纠错; (S104)将单位流划分为多层; (S105)对划分的层编码; (S106)使用预定方法映射分割图层; (S107)根据每一层的符号数确定每层的带宽; (S108)分配频域; (S109)对各层进行频率交织; (S110)进行快速傅立叶逆变换
