[tcpdump-workers] DLT Request for Radio Data System (RDS)
I am posting to request a value for DLT_RDS and LINKTYPE_RDS. Radio Data System (RDS) is a communications protocol standard published in 1992 for embedding small amounts of digital information in conventional FM radio broadcasts. The standard is also known as Radio Broadcast Data System (RBDS) in the US. References and Specifications: https://en.wikipedia.org/wiki/Radio_Data_System http://www.nrscstandards.org/SG/nrsc-4-B.pdf http://www.rds.org.uk/2010/RDS-Specification.htm Thanks, Jonathan Brucker. RDS Packet Structure +---+ | RDS Information Word 1 | | (2 Octets)| +---+ | RDS Information Word 2 | | (2 Octets)| +---+ | RDS Information Word 3 | | (2 Octets)| +---+ | RDS Information Word 4 | | (2 Octets)| +---+ |RDS Offset Symbol 1| | (1 Octet) | +---+ |RDS Offset Symbol 2| | (1 Octet) | +---+ |RDS Offset Symbol 3| | (1 Octet) | +---+ |RDS Offset Symbol 4| | (1 Octet) | +---+ Description: Note: the RDS frame is also known as a "group" in the RDS standard. The RDS frame consists of 4 RDS Information Words, each 16 bits, followed by 4 Offset Symbols, each 8 bits, for a total of 12 octets. The Information Words are as specified in the RDS standard. Encoding is Big-Endian, as in the standard. The Offset Symbols are ASCII characters representing the detected syndromes for the corresponding Information Words, and are used in the interpretation of Information Words, as per RDS standard. The valid Offset Symbols are: Offset | in RDS | bit sequence Symbol | Standard | in RDS standard ---|| "A"| A | 001100 "B"| B | 0110011000 "C"| C | 0101101000 "c"| c' (C-TAG) | 110101 "D"| D | 0110110100 "E"| E (MMBS) | 00 (from US RBDS Standard 1998, tables P.2, P.3) Sample Frames: d3 93 05 c8 e1 17 57 44 41 42 43 44 d3 93 05 c9 e1 17 52 20 41 42 43 44 d3 93 05 ca e1 17 33 20 41 42 43 44 d3 93 05 cf e1 17 20 20 41 42 43 44 The preceding 4 frames encode the following station: * Program Identification (PI) = 0xd393 * Station Name = "WDR 3 " * Alternate Frequency = 89.8 MHz ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers

How are various distros compiling? I would imagine either having two packages, or can it be compiled with both APIs? -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works| network architect [ ] m...@sandelman.ca http://www.sandelman.ca/| ruby on rails[ ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers

OK, so in this format the offset words are given as ASCII characters rather than as the bit sequences. I've assigned a value of 265 for LINKTYPE_RDS and DLT_RDS, and added an entry for it in http://www.tcpdump.org/linktypes.html; the update to that page probably won't appear immediately, but it should show up in 24 hours or so. ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
