Technical solution for receiving all available dvb-c channels at once?

void walker

Let's say I want to receive all the channels from my provider at the same time _{220 channels, 25 muxes or so}.
Is there any other solution other than having 25 tuners connected to the tvheadend server ? I know there's octa tuners, TBS6209se - 380 eur x 4 ₁₅₀₀ eur. Not ideal. I'd maybe pay that if it was all in one device, but I still need pcie splitter (I need my pcie slots for other stuff as well, so they'd have to be connected by risers and splitter), coax splitter, amplifier probably. Is it not possible to get a digital stream out of the RF signal that comes over fiber (rfog tech), with less hardware/shorter path ? I googled for many hours and couldn't find anything like this. Is it that expensive, electronics wise, to digitise ₁.4gbps worth of digital stream, coming over fiber ?

Hope there's RF guys here that can give a comprehensive answer. Thanks.

Not really, you need to demodulate all channels simultaneously, so while you can use a FBC Tuner you'd still need one demodulator for each frequency. I have built a DVB-C tuner for 31 channels/frequencies capable of blasting out a maximum of 1.6Gbit/s to Tvheadend and that tuner is based on a MaxLinear Puma 7 CPU and a matching FBC Tuner. It's however highly customized and the effort to get something like this built is likely worth more than the mentioned 1400€. The costs for the parts is less than 100€, but the development work needed is significant, on the hardware and software side.

Hey many thanks for replying, this is the first time I get actual useful info. Will research into FBC tuner thing, never head of those, and that Puma 7 CPU from MaxLinear. I am not doing anything commercial with it, it's mostly curiosity and a vanity project, I'd love to have a pcie card where i plug a fiber connector and get all tv channels on the other end. 1.6Gbit/s sounds like it would cover all of them on this provider. From your message I understand that you're willing to sell me a piece for a price, but more than 1400€. Please do PM your offer, maybe it will work, maybe not, we'll see. Do you think this has some commercial potential outside tvheadend nerds gang ? If so, might be worth to market and sell it somewhere.
