-----BEGIN PGP SIGNED MESSAGE----- Hash: RIPEMD160 I've found a design bug in eit.c: when gathering PSI sections for EIT decoding, the code assumes that the section numbers must be contiguous from 0x00 up to i_last_section_number, which isn't the case: ETSI EN 300 468 V1.5.1, p.23, "section_number": "Within each segment the section_number shall increment by 1 with each additional section, but a gap in numbering is permitted between the last section of a segment and the first section of the adjacent segment." I found that when trying to program an EPG application, the ARTE channel multiplex on Astra 19.2E would only show me the current and following events (in table_id 0x4e with just two sections), but none of the scheduled events (table_id 0x50 - 0x5f, with lots more sections with gaps between them). I reworked the code in eit.c to call dvbpsi_DecodeEITSections for each new section received, which made decode each section one by one, but my solution is a hack and clearly suboptimal. Any suggestions on how to patch this behavior?
