摘要:
A hierarchical broadcasting device and method are disclosed. In the hierarchical broadcasting method, a broadcast transmitting device may transmit lower layer broadcast data for an existing broadcast to a broadcast receiving device via a first communication network, and may transmit upper layer broadcast data for an improved broadcast to the broadcast receiving device via a second communication network. In this instance, the broadcast receiving device combines the lower layer broadcast data and the upper layer broadcast data in order to display the improved broadcast.

Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The coding unit (CU) blocks are divided into sub-CU blocks. The sub-CU blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of a CU block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.
