    • An apparatus (1001), system (1000) and method (800-900) are provided for improving the de-encapsulation of sections from Multi Protocol Encapsulation (MPE) (151) and Multi Protocol Encapsulation-Forward Error Correction (MPE-FEC) (152) Sections in a DVB-H transport stream. DVB-H is a standard for broadcasting services to hand-helds. Its difference from DVB-T, C, and S that is relevant for this invention is the presence of an additional layer of Forward Error Correction (FEC). Instead of restoring only correctly received sections (151) (152) the present invention also restores fragments of sections (151) (152) by using both Transport Stream packet headers (301. i.l) and section headers (151.1). As a result, entire sections (800-900) may not be erased (which can amount to up to 4080 bytes) whenever one or more fragments are received incorrectly, but only the incorrectly received fragments (which can be each up to 184 bytes) are erased. This leads to a more efficient use of the additional layer of Forward Error Correction (FEC) information.
    • 提供了一种装置(1001),系统(1000)和方法(800-900),用于改进来自多协议封装(MPE)(151)和多协议封装前向纠错(MPE-FEC)的段的解封装, (152)DVB-H传输流中的节。 DVB-H是向手持广播服务的标准。 与本发明相关的与DVB-T,C和S的差异在于存在额外的前向纠错(FEC)层。 代替只恢复正确接收的部分(151)(152),本发明还通过使用传输流分组报头(301.I.1)和部分报头(151.1)来恢复部分(151)(151)的片段。 结果是,一旦一个或多个片段被错误地接收,但是只有不正确接收到的片段(每个可以高达184字节),则整个部分(800-900)可能不被擦除(其可以达到4080字节) 被抹去 这导致更有效地使用附加层的前向纠错(FEC)信息。

    • The invention provides methods and apparatus for transmitting and receiving a source data block in a wireless communication system using hybrid automatic retransmission request protocol. According to the scheme provided by the invention, at transmitting side, the source data block or part of source data block that is not decoded correctly at receiving side is divided into a plurlaity of data segements, each the plurality of data segments may be paded with known data to expand the data segments to be a predetermined lengthen, the data segment is encoded with linear code to be a data packet including the data segment and a redundancy information segment or including only redundancy information, and after that the encoded data packets are transmitted. At the receiving side, when each of the received data packets includes a data segment and a redundancy information segment, decoding is performed directly based on the received data packet, decoding is performed based on the received reduandancy information segment and an data segment and redundancy information segment extracted from buffered data packets with a first and second chance to restore the data segment that is not decoded correctly in previous decoding processing. With the additional decoding chance, the scheme provided by the invention can improve decoding probability and thus the transmission efficiency of the system.
