Okay, replying to my own question. Looks like there's an amendment at the bottom of A_65C that says to use the ATSC Code Point Registry. So 0x5 is the correct service_type for software download streams. Doh! I've been reading specifications for years, and I still get hornswaggled. Ron Ron Economos wrote:
The local PBS station KQED-DT has started a DTV receiver firmware update service. The new streams are included as programs 8 and 9 in the Transport Stream PAT. Unfortunately, users have been reporting that DTV receivers are including these data programs in the reported channel map (as 30.8 and 30.9 along with the correct 9.1, 9.3 and 9.3).I took a look at the stream, and also the software download specification:http://www.atsc.org/standards/a_97.pdf A_97 states that there should be a PSIP TVCT entry for the data streams with the service_type field set to 0x5. However, A_65C: http://www.atsc.org/standards/a_65cr1_with_amend_1.pdfstates that service_type 0x5 is reserved. So the question is, what's the correctsetting of service_type for software download streams? KQED-DT is not currently sending any TVCT entries for the softwaredownload streams (although they just started sending the streams, so maybethey just haven't got around to updating their PSIP generator).
