摘要： The present invention offers a method for channel change in digital broadcasting consisting of: a step 1 for recognizing a command for a channel change while the currently connected channel is being decoded at the digital broadcasting terminal; a step 2 for completing reception of the current stream while maintaining the received picture if there is a command for a channel chang according to said step 1; a step 3 for receiving and analyzing the information of the newly con¬ catenated stream without re-initializing the decoder and concatenating two streams; and a step 4 for renewing information of the newly concatenated stream in order to maintain continuity between the previous stream and the newly concatenated stream using the information obtained in said steps 2 and 3. Therefore, time delay during channel change will be minimized by changing channels without decoder re-initialization and without break in the channel changing time.
