摘要： A system and a method are provided for processing Multi-Protocol Encapsulation (MPE) under the DVB-H standard. The system includes: (a) a receive buffer having entries organized as columns and rows and in which the addresses for the entries in the receive buffer are arranged sequentially in column-major order; (b) a first process writing MPE data into the receive buffer, in the manner such that, for each frame, the application data portion and the error correction code portion are written sequentially in column major order, (c) a second process decoding the error correction code portion of each frame and which corrects the application data portion in accordance with the decoding; and (d) a third process reading out the application data portion from the receiver buffer column by column, the third process re-reading any column of the application portion that is corrected by the second process, when that column has previously been read by the third process. Under this system, the first process (a) keeps tracks of the locations of the MPE data of each frame in the receive buffer in a mapping table, and (b) writes the MPE data of a next frame is written into the locations of the error correcting code portion of a previous frame, when the locations become available.
