FIELD: physics, communications.
SUBSTANCE: invention concerns digital broadband data transfer systems, particularly decoding of frame error correction of multiple-protocol encapsulation (MPE-FEC) in handheld digital video broadcasting system (DVB-H). Invention claims method and device for MPE-FEC frame decoding in DVB-H. Filtration of packet identification (PID) is performed in TS packet received over wireless network to identify TS packet, and table ID is detected by data heading information intended for identification of section data type. If section data are MPE section, then the frame is buffered. If after IP datagram storage for last MPE section some part remains in data area, then remaining part is augmented with zeros. If section data are MPE-FEC section, then frame is buffered based on parity data obtained from MPE-FEC section.
EFFECT: efficient method of MPE-FEC frame decoding in handheld DVB-H for reception of transport stream (TS) packet and Internet protocol (IP) datagram reconstruction.
