Abstract
An encoding method for wireless transceiving of multimedia data including video data, and an encoding device therefor are provided. The encoding method includes (a) generating a length field representing the number of bits of a payload, (b) generating an error correction code by performing error correction coding with respect to the length field, and (c) inserting the length field and the error correction code during radio link protocol (RLP) framing. The encoding method reduces overhead when multimedia data including video data is transmitted and received under the radio environment, and increases error robustness, thereby improving the quality of an image.
