Hi,

	I've written some code that will download the MHEG data that is
broadcast on DVB channels. This is the "Red Button" interactive TV stuff
here in the UK.

	The code is GPL'ed and is available here:

http://www.redbutton.dsl.pipex.com/

	It only implements a subset of the whole DSM-CC specs. However,
it is enough to download everything that is currently being broadcast on
the 'Freeview' DVB-T channels in the UK.

	Once the data is downloaded, you'll need to write your own
browser/app to display it!

	As well as PNG files, you get two types of data. Channel 4
broadcast teletext infomation in an HTML type format, except the tags
are things like <pages> and the text contain some escape sequences
followed by what look like terminal control codes. The BBC broadcast
data that is encoded in ASN.1 format.

	You can get more info about MHEG here:
