6.1.2. INTERNET TERMINAL
The internet terminal described here is an
optimized implementation where the STPC Atlas
board is integrated into the CRT itself. The
advantages are a reduced overall cost and a good
image definition.
The STPC Atlas platform being integrated into the
monitor itself enables the choice of a limited
amount of horizontal frequencies and simplifies
the CRT driving stage:
- 1024x768: 56.5KHz horizontal, 70Hz vertical
- 800x600: 53.7KHz horizontal, 85Hz vertical
Like for the Thin-Client, an external MPEG
decoder can be connected to the STPC Atlas
through the PCI bus and the Video Input Port.
The same concept can be applied using a TFT
display instead of a CRT.
