WaveTV 0.5.0
This is a pretty shallow documentation for the WaveTV application.
Features
-
TeleText browser with Auto Grabbing. (when reading TeleText pages, all
the "sub" pages are automatically captured).
-
Frame Grabbing.
Installation
-
VideoHandler
If you want to use the frame grabber you have to compile and copythe
VideoHandler data type that comes with the Datatypes library into the directory
/boot/system/add-ons/Datatypes/
To safe you from some of the work, I have included a compiled version.
-
Plug a Bt848 card into a free PCI slot :)
-
Copy the Bt848 driver into /boot/system/drivers, the newest version can
be found at ftp://ftp.scruz.net/users/sakoman/public
-
Copy the WaveTV application anywhere you want it.
-
If you don't know what the Bt848.xMAP file is, just delete it.
Usage
I hope the application is so easy to use that I don't have to write anything
here :)

Known problems
-
Frame Grabbing
Currently it is only possible to capture in the raw Mediaformat (mhi!)
Sometimes the grabbed frames will have some noise in the right side.
-
Auto scanning for channels
On some cards ALL the channels are added to the channel-list.
-
TeleText
It is possible to open the TeleText browser, even it the required hardware
are not found.
Sometimes a page full of question marks is shown.
The TeleText cache is global for all channels, so sometimes a page
from another channel is shown. If the current channel has this page, the
right page will be shown when it is received.
Double height, flash and hidden text are not supported.
-
Sometimes the contents of a window is not resized when the window is.
-
SVideo input has not been tested, so if there are any problems (video/audio),
please let me know.
-
16bit colorspace has not been tested.
Stuff i will (hopefully) add later:
-
TeleText on ALL Bt848 cards
I Thing this is possible with the VBL data capture feature in the Bt848
chip. The necessary functions in the Bt848 driver is not yet there.
-
Save audio when grabbing movies.
-
Decoding of Intercase data.
When I get find some documentation on the Intercast format, a european
TV-station starts to send it and the Bt848 driver gets the VBL data capturing
functions, I might try to implement it :)
-
TopText and FastText
As soon as I find out exactely what it is, some documentation
(and find a local station that broadcast these).
-
FM Radio support
Tested cards
Hauptpauge Model 418 - Works ok, the FM radio is not yet supported.
