The invention provides a method using a recording and broadcasting device to record and broadcast TV programs; the method comprises the following steps: allowing a first recording terminal to start aTV program, sending a recorded TV program to a processor, and allowing the processor to receive the video data recorded by the first recording terminal and process the data; detecting recording interruption or recording failure caused by other reasons, sending a start recording order to a second terminal, and switching the TV program recording task to the second recording terminal; allowing the processor to build a peer-to-peer protocol between the first and second recording terminals, and enabling the first and second recording terminals to share the recorded video data. The two recording terminals can both watch the complete TV program, and the TV program can be stored for a long time for users to watch, thus saving resources, and ensuring the TV program watching completeness and smoothness.
