Date: Fri, 29 Apr 2005 18:51:08 -0400 (EDT) From: John Wehle <john@feith.com> To: multimedia@freebsd.org Subject: FreeBSD 4.9 / 5.3 Hauppauge PVR-250 / 350 setchannel (Feb 09, 2005) Message-ID: <200504292251.j3TMp8hj020341@jwlab.FEITH.COM>

This version supports:
1) Changing the channel map / TV standard used by the driver at runtime.
$ setchannel -m 2 # Selects US Cable channel map / NTSC
2) The desired channel can now be specified either as a channel number
or as a frequency in MHz.
$ setchannel 4 # Selects channel 4
$ setchannel 229.25 # Select US Cable channel 25
3) The radio can be chosen as input (and is tuned by specifying the
frequency in MHz).
$ setchannel -r # Selects the radio
$ setchannel 89.1 # Sets the radio to 89.1 MHz
BTW: I noticed at least one posting talking about the "odd" non-standard
sizes support by the driver ... all the size are in fact * standard * ...
it's just a question of which standard. The relationship is:
352x240 VCD 352x480 DVD (half D1)
352x288 VCD 352x576 DVD (half D1)
480x480 SVCD 720x480 DVD (full D1)
480x576 SVCD 720x576 DVD (full D1)
Enjoy,
John Wehle
