Abstract
A method for processing a channel switching failure case is disclosed. The method for processing a channel switching failure case is used to provide media services for receiver in unicast and multicast modes and includes: detecting whether a data stream is of failure case after sending a channel switching request; and sending a failure case message and/or a failure case processing message to a channel switching server when a failure case occurs so that the channel switching server may process the failure case. A terminal device and channel switching server are provided so that the channel switching server may recover channel switching services provided for receiver and provide correct services for a user.
