Watching 8 channels at once

Added by Jim McDonnell about 5 years ago

Hi all. First post. Might be a daft question but here goes. No problem or issue here, just a question.

I just bought a Hauppage dual DVB-T/T2/C tuner and connected it to a Raspberry Pi running TVheadend.

To my surprise, I can watch or record 8 (eight) channels at once. How is that possible? I know that 3 channels can be streamed with 2 tuners, so long as no more than 2 multiplexes are involved. But 8 ? Astonishing.

I chatted to "Elton" at Hauppauge support, asking the same question. He says is it is all down to the software.

Setup details:
Server: Pi 4 running Raspbian Buster, HTS Tvheadend 4.2.8-34, Kodi 18.4.
Client: I watched 8 channels using 8 instances of VLC 2.2.2 on my laptop, an 8 core machine running Linux Mint 18.3.

Cheers,
Jim

1 tuner = 1 frequency
1 frequency = 1 transponder/mux
1 transponder/mux can contain multiple services

There is examples for 42 tv services on one transponder

Yes I know. How can this new Hauppauge tuner allow the streaming of 8 services when older tuners (eg. the ones in my Topfield) are restricted to 3 maximum?

Incidentally, this isn't mentioned in the Hauppauge instructions or website. Both claim a maximum of 3 streams for the tuner. Nowhere is 8 mentioned.

There is no such limit on any device, except if there is no pid limit but such are not made from 15 years.
