Can you elaborate on that? What exactly is the problem? And what kind

I don't know if the Linux kernels used for audio-video consumer gear are
used for audio and video processing, perhaps they are just used to
provide menus etc., but since the end of the 90s I never experienced the
good audio and video sync we had with German terrestrial analog
television. All analog and digital satellite and digital terrestrial
receivers I've seen didn't provide acceptable sync. Assumed at least
some of those receiver should do the audio and video processing using
Linux too, a smart solution to fix such issues, not by just providing
fixed delays, but by detecting the exact drift and automatically fixing
it, might be from interest for the consumer gear companies. Perhaps,
they wouldn't care about a smart way to fix it, OTOH for colour
correctness at least Germany cared, so we once upon a time got PAL.

you did see that ? I'm surprised. Which brand ?
I've worked for two years on the A/V testbenches for sagemcom making a whole 
lot of digital satellite receivers and never noticed that.
Until two years ago they used an RT system on STM32 processors. The move to 
embedded linux was quite new, maybe introducing this issue.

I don't remember the brands of the satellite receivers I owned
(discounter thingies), but a friend repairs receivers, so I've seen a
lot. Many people in German switched to DVB-T, I can see it on my THOMSON
DTI series 500. It could differ for different broadcasts of the same
station. My claim isn't that the receivers cause the sync issue. I
remember that at least some satellite receivers provided to manually set
a delay, but AFAIK no auto-syncing option does exist (similar as PAL to
ensure colour stability). My DVB-T receiver seems even not to provide to
set a delay manually.

And I don't claim that THOMSON does use Linux, perhaps, perhaps not. I
only want to point out that lip-sync is a known issue in Germany and
that lot of consumer gear does use Linux. The lip-sync issue might be
caused by the station or anywhere in the chain from station to receiver.
If somebody would event something, that could automatically fix it, this
perhaps could become the next great invention, after the invention of
PAL.

This has become offtopic!
Please change the subject. I am very interested in Linux Audio jobs and 
companies but not at all in discussions that got ralfed.

Thank you.

[LAD] Linux audio jobs/companies?

2014-09-27 Thread Bill Gribble
It's job hunting time, and while I am skeptical that there are very many 
paying jobs for Linux audio developers out there, I thought I'd at least 
ask on this list.  What companies are doing work in the Linux audio 
universe?


Or, on the other side, anybody know of interesting 
music-instrument/audio companies located in or around NYC (where I live) 
who might need Linux folks for their web presence or other online stuff?


Any tips appreciated!

Thanks,
Bill Gribble

A lot of consumer audio-video stand alone gear is using Linux, e.g.
television satellite receivers. IMO this market might be more
interesting when searching for a job, than the pro-audio market or
Internet presences are.

Just 2 Cents ;),
