A, so called, "full-featured", revision 2.2, DVB-S PCI card.
Linux Support for these cards is quite stable.
Overview/Features
Originally derived from the old Siemens DVB-C card design. The Rev. 2.2 is Sold by:
- Hauppauge as the WinTV-Nexus-S.
Based on an SAA7146 PCI bridge and an onboard AV711x MPEG-2 Decoder. Over time these cards have used many different demodulators and tuner modules; some examples include the STV0299 and the TDA8083.
The, so called, "full-featured" cards look quite old-fashioned now, but nonetheless, they have worked reliably for a long time and have been the base for Projects like VDR. However, a major drawback of the "full-featured" card design is the low maximum Bus Bandwidth limit inherent to the AV711x, and which effectively means that, because of this, HDTV receiption or raw MPEG-2 Transport Stream access is not possible. Since even MPEG-2 decoders implemented in software perform well on HDTV sources when run on modern PC systems, there is usually no need for cards with onboard MPEG-2 Decoder today. An exception may be special software that relies on proprietary card features like VDR (although, even in that case, you can also use the VDR Software Decoder Plugin which effectively allows you to use any card you want with VDR)..
