For the type of the error code stream, the present embodiment lists two types, but the type of the error code stream is not limited to the two types. The first type of error code stream is that the channel code stream is copied into the same two copies during the transmission process due to some special reasons, such as service network abnormality or improper switch configuration. The stream cannot be decoded normally and is an abnormal code stream. The second error code stream is that the multicast address and port number of the code stream are the same as the multicast address and port number of an original channel code stream in a certain period of time, because The error code stream interferes with the original channel code stream, and the error code stream is a repeated code stream. For example, the original code stream 1 multicast address is 239.255.1.1, and the port number is 1234. Meanwhile, the code stream 2 multicast address also uses 239.255.1.1, and the port number is also 1234. Then code stream 2 will interfere with code stream 1, and code stream 2 is the repeated code stream.

At this time, the error code stream is a repeated code stream. For example, the original stream 1 multicast address is 239.255.1.1, and the port number is 1234. At the same time, the stream 2 multicast address also uses 239.255.1.1, and the port number is also 1234.

The first type of error code stream is caused by some special reasons, such as service network abnormality or improper switch configuration, resulting in the channel code stream being copied into the same two copies during the transmission process. The stream cannot be decoded normally and is an abnormal code stream. The second error code stream is that the multicast address and port number of the code stream are the same as the multicast address and port number of an original channel code stream in a certain period of time, so the error code stream may interfere with the original channel code stream. At this time, the error code stream is a repeated code stream. For example, the original stream 1 multicast address is 239.255.1.1, and the port number is 1234. At the same time, the stream 2 multicast address also uses 239.255.1.1, and the port number is also 1234. Then code stream 2 will interfere with code stream 1, and code stream 2 is the repeated code stream.

The first code stream may be any one of the abnormal code streams having a normal multicast address and a port.

In step 370, the code stream to be decoded is output.

The code stream to be decoded outputted in step 370 is a channel code stream that is detected and filtered. When the channel code stream is a normal code stream, the channel code stream is output as a code stream to be decoded; and when the channel code stream is an error code stream, The channel code stream is filtered, and the filtered code stream is used as the code stream to be decoded.
