Hi,

As subject says, which CRC-code is used in TS of DVB?

I think I've read CRC32 somewhere - is that correct?

it's CRC32, the decoder model is described in ITU-T H.222.0, Annex A.



Is there any chance that CRC32 will be added to DVB-driver for
low-budgets?

It's implemented. Set the DMX_CHECK_CRC flag in the
dmx_sct_filter_params struct if you want only receive sections that
passed the CRC32 check.
