The chan i fsi0 nel switching method comprises the following steps: after a televi /-I sion performs channel switching, monitoring a code stream of a fre quency point where a marked channel is located; determining whether the type of the code stream is a programme stream, wherein S20 the type of the code stream comprises a programme stream and an r1W 4 A } % advertisement stream; and if so, switching a current channel back to the marked channel. Also disclosed is a channel switching device. = 7 2AA S3 The present invention solves the problem that it is difficult for a 11 Aff Fol 4d- iCMPiaS30 user to switch back to an original channel on time to continue I watching a target programme after an advertisement of the original m channel is played, thereby improving the punctuality of channel S10 AFTER A TELEVISION PERFORMS CHANNEL SWITCHING, switching.
