If you're using avconv, then you're on the wrong mailing list, or using
the wrong tool. The command line tool discussed here is ffmpeg, which
can be obtained from
http://www.ffmpeg.org/

I don't quite understand your sentence, but if it's correct that you
want to deinterlace the input before providing it as output, you need
to insert a deinterlace filter with "-vf". The possible filters have
been discussed already.

No difference, except that you change your output to .ts (or you
provide it to the network, e.g. with "-f mpegts -listen 1
http://localhost:port").

That will change as soon as you insert the filter, as it needs CPU.

BTW, I don't know whether your hardware accelleration can do
interlacing, but even if it did, I think ffmpeg wouldn't support it.
