Embodiment Construction
[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] figure 2 is a simplified flowchart schematically illustrating a method 200 for multicasting in wireless communication according to the present invention. As shown in the figure, the method 200 starts at step S201. In step S202, the method 200 extracts bits with the same importance level from each video block in the video frame, so as to form multiple data streams with different importance levels. Next, the method 200 proceeds to step S203. In step S203, the plurality of data streams are respectively encoded sequentially and cyclically using a plurality of different encoding rates. Then the method 200 proceeds to step S204, wherein the encoded data streams are divided into multiple groups according to the importance level and different powers are allocated to each group. Then the method 200 proceeds to step S205. In this step S205, multiple...
