In March 2005, Philips Semiconductors announced "the industry's first integrated PCI Express dual global video and stereo decoder for digital home PC desktops and notebooks" (press release). The new analog decoder chip, the saa7162, uses the increased bandwidth of the PCI Express bus to capture to two simultaneous analog channels of live tv or baseband video (cf. product flyer) or up to four independent simultaneous digital TV streams (cf. Philips/NXP SAA7162 data sheet).
As at Oct 2006, NXP just put a page up with the specifications, including an 18 page data sheet: SAA7162 Product Description
According to Philips' reference design, there's a Linux driver; someone needs to e-mail Philips to get it.
TV cards that use the PCI Express bus are marketed as TV Tuner ExpressCards.
The PCI-SIG lists SAA7162 (dual A/V decoder) and SAA7160/SAA7161 (multimedia A/V bridge) as PCIe devices. The CX23885/6/7/8, found on some of these cards, are also PCIe chips.
