Teletext4WWW

Teletext4www is a system that allows you to browse teletext pages with your webbrowser. It has two main modules:

grabber - demon, witch is grabbing all pages 'from air', recognizing channel, storing them at disk
renderer - cgi-scripts (method can change), witch generates indexes of channels/pages, renders them, allows to browse them easly

Implementation issues/system requirements (it can change):

OS: Linux (or other system with compatbile vbi interface)
Language: C (for demon part and renderer), sh/perl (for helper and cgi scripts)
Used libraries/aplications: libpng (for page rendering), libz (for page storage), libvbi (for vbi device interface and page rendering - taken from AleVT), v4lctl (for switching channels - from xawtv).

System (dis)advantages:

it is storing all pages, and you browse archive (+)
you can share it with others (teletext often contains various information pages) (don't know all legal issues, they can be very-stupid, especially in US) (+)
it can work all the time, constantly building page-cache (+)
disk space (it have to save all grabbed pages on disk) (-)
refresh rate of content is low (when you are getting pages from many diffrent tv stations) (-)

Project history/news:

	3 Jun 2003
Some code cleanups (added comments). You should be able to compile and use whole aplication from cvs co of txt4www module - but you're on your own with configuring it (it should be easier with in-source documentation).
	23 Mar 2003
Creation of project homepage.
	6 Mar 2003
First files of the new project: libvbi2 (taken from AleVT 1.6.1), sample programs (from old teletext4www). Go to cvs for it (unusable).
	Feb 2003
Idea of redo'ing all the project. Registration of the project on Sourceforge. Initial commit of the old version.
	Aug-Nov 2000
Ancient history: from the idea (to share teletext with other users of LAN) to its first working implementation. Work done with Souti.

Links:

AleVT - great teletext viewer program (libvbi2 is taken from it).
XawTV - great TV-watching program (some tools used in scripts goes from there).
ETSI - standardization organ. You can get Teletext specyfication from there or there (newer version).
My several, simple programs - maybe something will interest you.
