TCL symbol rate

[cyril]

So does anyone know the symbol rate of TCL's service?

This is what I found:

QAM = 64 (off the Set Top Box startup)
Symbol Rate = 6956.5 (Found the hard way)
Transponder Frequencies = 586 - 650 at 8Mhz jumps. (Off the NIT / Set Top Box)

Below is the cables.xml I use with my Dreambox. This is what I received off the NIT in Wellington. I had to "blindscan" from 4000-7000 KSyms by creating a custom cables.xml on frequency 626Mhz and steping through each symbol one by one which took about 3 hours counting up from 4000 to 7000... just wished I had counted backwards from 7000 instead of starting at 4000 as it would have come up much faster. I have had reports that Christchurch uses the same Symbol Rate, just has its channels on different PIDs.

Cool, I would have thought that scanning the band in 50kHz or 100kHz would have been fine enough in the UHF band, 8kHz is a bit harsh.

For DVB over Cable from what I have seen worldwide it's pretty common to have 8Khz jumps per TP (or is that 8Mhz? :)... Then combined with the symbol rate they can get 10 DVB MPEG2 Video streams per TP. 9 TP's and 10 Video streams per TP comes at 90 channels... somewhat less than what is going over the cable at the moment, plus TCL could always add more TP's above 650.

It will be 8MHz as that is the standard UHF band spacing, for NZ and most other countries and virtually all cable operators.

Oops my bad on that one... Changed my original post.

Kilohertz Megahertz... What's an extra thousand between friends :)... My head hertz :)

Are all the channels scrambled or are some clear?

[cyril]

All scrambled.
