Disclosed is a method for transmitting streaming media data, applied to a streaming server, including: determining priorities of data blocks of different types in streaming media data; respectively encoding the data blocks in the streaming media data to be broadcasted live currently to generate corresponding redundant codes; and after the streaming media data to be broadcasted live currently are completely sent, sequentially sending the redundant codes corresponding to the data blocks according to the priorities of the data blocks in the streaming media data from high to low.

Streaming media data transmission method and apparatus

The present disclosure discloses a method and a device for bandwidth self-adapting data ranking protection. The method comprises: performing redundancy protection computation on a data block to be transmitted so as to generate a redundant code of the data block, and setting a priority for the redundant code; determining whether bandwidth occupied by a redundant code with a highest priority is greater than current residual bandwidth; if the bandwidth occupied by the redundant code with the highest priority is not greater than the current residual bandwidth, carrying the redundant code with the highest priority in the current residual bandwidth; otherwise, according to a descending order of the priority, searching in residual redundant codes for a redundant code whose data amount is less than or equal to the current residual bandwidth, and carrying a found redundant code in the current residual bandwidth. The present disclosure improves the error tolerance of a system.
