Abstract:
1. A method for processing audio data by an audio data decoder, comprising: receiving, by the audio data decoder, frame type information of a current frame; obtaining previously received frame type information of a previous frame by an information extracting unit of the audio data decoder, wherein the frame type information specifies a relationship of positions of the frame and a block included in the frame; obtaining frame identification information of the current frame based on the frame type information of the current frame and the frame type information of the previous frame by a frame identification information generating unit of the audio data decoder; and identifying the current frame using the frame identification information by a frame identifying unit of the audio data decoder, wherein at least one of the frame type information of the previous frame and the frame type information of the current frame corresponds to a fixed type or a variable type, wherein the fixed type indicates that a start position of the frame coincides with a start position of the block or an end position of the frame coincides with an end position of the block, and wherein the variable type indicates that the start position of the frame fails to coincide with the start position of the block or the end position of the frame fails to coincide with the end position of the block.
