摘要 |
A transmitting method, a transmitting apparatus, a receiving method and a receiving apparatus of a digital broadcasting signal are provided to divide a stream into a plurality of layers according to a characteristic of the stream, process each layer independently and dynamically allocate a frequency based on the processed signal. A single stream is divided by a predetermined stream unit. Importance of the divided stream unit is grasped. According to the grasped importance, the divided stream unit is allocated to a plurality of layers(S104). Encoding and mapping about a separate layer are performed(S105,S106). Resources about the separate layer are dynamically allocated based on a symbol number about the separate layer(S107,S108). |
