Load the Channel Mapping of Cable Clearqam

<toc><ul><li><link topicref=“2”>Steps</link></li><li><link topicref=“3”>More detailed reading</link></li></ul></toc> Cogeco Cable also uses the standard &quot;scte65&quot; to send the channel mapping for clearQAM channels to their digital adapter boxes for analog TV's.

You can pull down this channel mapping with a tool called 'scte65scan'. The tool will generate SQL for direct import to MythTV.


1. Download and built the latest version of scte65scan from SVN. The mythTV wiki describes a problem where mplexids are not unique in the release version.

[email protected]:/usr/src# cd scte65scan/
[email protected]:/usr/src/scte65scan# make
cc -g tunerdmx.c scte65scan.c -o scte65scan

2. Scan your digital adapter for an scte65 signal, and note the (4 Digit) VCT-ID that matches the channel line-up you see.

[email protected]:/usr/src/scte65scan# ./scte65scan -A 1 us-Cable-Standard-center-frequencies-QAM256
VCT_ID 4011 (0x0fab) at 387012500hz, version 22
   2   88.2   2 TVO    (CICA)
   3   92.3   2 Global

3. Perform the same scan specifying the VCD-ID and generating the SQL output for MytvTV. My digital tuner card is source ID 2 which I have specified (,2) in my command

[email protected]:/usr/src/scte65scan# ./scte65scan -A 1 -V 4011 -f3,2 us-Cable-Standard-center-frequencies-QAM256 &gt; vct.sql

4. I can now import the resulting SQL after I have looked it over that it seems to be correct (you will need to manually correct things like the extra ' in some station names).

mysql -u mythtv -p mythtv &lt; vct.sql
