TV500 stuff
astv
astv is a remote control for tv500 compatible tv cards. It does not
actually handle displaying video, but instead is a remote control for the
xavtv display program by Chris Bagwell. The latest version of xavtv is
available here.
If some features are not working, you might try getting my version of xavtv.c
which may have a few enhancements not yet merged in by Chris Bagwell. I try
to keep him updated with any bug-fixes or changes I make, but sometimes I
may not be in sync with his latest version. The versions of astv (this
name will more than likely change sometime after I figure out a better and
more descriptive one) after v0.5 were written using
Glade so you need GTK+ in order to compile
it. Information on doing so is in the included README file. Previous versions
required the xforms library available at

Stuff below here is kinda old, but some of it may still be applicable, so
I've left it on this page.
stv500
I can't get my TV500 card working in overlay mode with my S3 video
card, so this software may or may not work in overlay mode. I am
concentrating mainly on capturing both still-frame and video (eventually).
The software currently saves the captured image in .ppm format. There is
also a problem with the sync sometimes. The picture will be incomplete or
will be shifted up/down and/or right/left. To capture an image, just
move the tv window around or move the cursor inside the window. I know,
this is hokey, but I'm still working on the program and don't have it
updating automatically right now. For display in X, the program will
use normal XPutImage or it can use the MIT Shared Memory Extensions and
use XShmPutImage for faster updates. This is specified in the makefile
currently with the current default being use Shm extensions.
Because this is built upon stv500-0.7, it incorporates the channel lists
from that version. The program is currently set to use the vhf/uhf
frequencies, if you wish to change this, go to line 51 of remote.c and
change the variables assigned there. Eventually this will be an option
under the Settings button.
Currently working features/buttons (there may be more).
- Volume Up/Down & Mute.
- Channel Up/Down.
- Channel Touchpad (punch the numbers you want for the channel).
- Capture (basic functionality).
Buttons in the X remote used for testing...
- Cap(ture) - this will pop up a box asking you for the filename to
save the captured image as. The file will be saved in .ppm format
in the directory in which xr was run.
- Fr(eeze) - this will re-capture the image.
- Settings - this will help correct sync errors by shifting the image
down by 1 pixel.
- Style - this will help correct sync errors by shifting the image
right 1 pixel.
- '?' (help) - this will toggle back and forth between the tuner and
video/audio in.
