Abstract:
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.1) 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.
