2014.02.26 Hauppauge Press release: http://www.hauppauge.com/pdfs/pr_hauppauge_wintv-hvr-1975.pdf "We expect the WinTV-HVR-1975 to be used in Linux based systems for digital signage, sports equipment, hospital patient entertainment systems and other TV watching and high speed data delivery applications"
"For Linux system builders, Hauppauge has driver support which can be provided under NDA." LinuxTV.org Hauppauge WinTV-HVR-1950 https://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-1950 Note: As of August 2014, the WinTV-HVR-1955 is sometimes shipped instead of the HVR-1950. The HVR-1955 does not, at this time, have a open-source driver available. A source-level driver for Linux is available from Hauppauge after a NDA is signed. Hauppauge technical support can be contacted for more details. >From the above, I'm ascertaining the HVR-1955 is possibly the HVR-1975, or similar situation. Judging by the press release, I'm guessing contacting Hauppauge will result in the firmwares being released after a NDA is signed. I'll take a gander, likely one or two chips (or maybe some of the code for the firmware) have questionable disclosures attached during the engineering/manufacturing process. And may or may not be provided openly at a later date. But then I stumble back on this thought, and if it's just the firmwares, we should be able to extract them from the Windows' driver package. Take a further look at a mailing list post by dheitmueller at kernellabs on Mar 7, 2016, 7:39 AM (Post #9 of 15) http://www.gossamer-threads.com/lists/mythtv/users/597124 I think dheitmueller did a good job explaining some of the material. (I prefer to copy the material here, but think I've wrote enough already.) Of course that list ends up recently asking this list for further information! But as dheitmueller stated within his post, or somebody immediately following his post, the Linux HVR-1955/1975 drivers are posted on this page. http://www.hauppauge.com/site/support/linux.html kernel 3.16 http://hauppauge.lightpath.net/software/linux/linux-ubuntu-14-04-2.tar.xz kernel 3.19 patch http://hauppauge.lightpath.net/software/linux/hvr-9x5-19x5-22x5-kernel-3.19-2015-07-10-v2.patch.tar.xz kernel 4.2 (already has) built in support for the WinTV-HVR-955Q. At this point, I'm wondering if the drivers also for the HVR-1955/1975 are included within kernel >= 4.2? Interesting, does the original poster have access to the Internet, or to hauppauge.com? > On Mon, Sep 12, 2016 at 05:35:17PM -0500, [email protected] wrote: > (snip) >I know basically nothing about the HVR-1975.

Your over-the-air broadcast TV is of slightly better quality and it's free. One just needs to know how to install an antenna, cabling, etc... I've even experience broadcast TV having superior quality audio versus Cable TV, but that was a few years ago. -- Roger http://rogerx.freeshell.org/ _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
