- Can handle multiple boards!
- Particularly optimized for live broadcasting, visible count down to next game refresh.
- Can handle time tag (if properly added, optimized for iChess broadcasting system)
- Easy configurable, use your html file or configure directly via the URI
- Extremely easy to insert into own web page, just insert three lines into your html file, and it will work (see Demos and Information).

Thanks and Contributions
The Viewer is originally based on the javascript code of Lutz Tautenhahn, he has written a whole bunch of functionality not only for live broadcasting but has also included many other features. Have a look on his homepage. Many thanks for this great start.
The nice .png pieces have been taken from http://chesstempo.com presumably a .png conversion of the free merida.ttf font by Armando Hernandez Marroquin and Circolo Lasallista de Ajedrez. The png handling for IE06 has been derived from a JS code example of Drew McLellan. There are many other solutions out there, but this is particularly well documented and instructive.
Last but not least, I got many ideas and help from various wikipedia (en,de) entries. Many thanks to all of them.
Known Bugs and further improvements
Currently there are no known bugs, if you find one please report it to Felix@ichess.de
Further planned developments:
- Selective upload: the required bandwidth for many clients could be substantially reduced, if only the new moves are transmitted (which could be also used to update more frequently). As the client request is already implemented as an Ajax httpRequest, a selective upload could be done with a small php program, rather than just loading the pgn file.
- Elapsed time count down, this requires some kind of clock correlation with the chess server and the clients
- Provision of timestamp for last pgn file update (take care of ftp upload issues)
