<p>A transmitting, receiving method and apparatus for realizing service data recovery are provided. And a protecting method and a channel protection system with corresponding transmitting/receiving apparatus in the event of a failure of the channel are provided. The channel protection method includes that: each service channel for transmitting the service information is in-band redundantly encoded; setting one to more out-of-band channels as the standby channels; when the random/correcting error is generated in the service channels, the service channel is error corrected via in-band redundant encoding; when the uncorrectable error/failure is generated in the service channel, the service channel is error corrected via the standby channel. Each embodiment of the present invention resolves the question that the service instant break can not be avoided in the prior art and the little error and the big error can not be effectively protected simultaneously, the reliability of the telecommunication network/device can be improved, the flexible protection for little system and big system is realized.</p> |
