If you are looking for a PCI card that provides Ethernet ports, they are widely available. US$12.99 for 10/100 Mbps http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=252929 US$18.99 for 10/100/1000 Mbps http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=252918 (I don't know if these particular cards are good or not, but if not there are lots of choices.) Or do I misunderstand you, and you want a device that works the other way around? One that plugs into Ethernet and provides a PCI slot? The only way I know of to do that is to use a computer. I am always short on slots, and would love to find a Ethernet/SCSI/USB/Firewire/whatever-to-slot adapter. > Of course a T base 1000 is better, is it more expensive ? The prices of 1000 Mbps PCI Ethernet cards are pretty low now. I'm pretty sure I've seen lower prices than the ones above. (again, the cards might be low quality, I don't know) Prices on 1000 Mbps hubs/switches still seem quite a bit higher than prices for 100 Mbps. > Moreover, I suppose that if the g-card in the terminal has to decode, it > will be a little more hot and more expensive. According to the nvidea pdf that Vesa recently posted a URL to, http://www.nvidia.com/object/TB_purevideo.html it takes less power (longer battery life) to decode using graphics hardware than decoding with software in a general purpose CPU. Of course nvidia is biased. My hope is that the OGC chip will handle enough of the decoding that we can use an inexpensive, low power CPU. > Anyway, can we envisage in the flat panel a board with an Ethernet > connector and a PCI slot on which one plugs the g-card ? If you want to do it that way, you would need a board with CPU, memory, Ethernet chip, PCI slot, and a few other things. I was thinking of taking the OGC chip and putting it directly on that board. Save the cost of the PCI connectors. > Does that require a "special" chip between the PCI slot and the Ethernet > connector ? Ah, perhaps this is what you were trying to get at above. If you want a single chip it would probably have to be special. I think we can do it with a few off the shelf chips, but I expect it would take more than one. It would be really nice if we could find a way to avoid needing a general purpose CPU. > And here, the idea to offer a monitor with a g-card inside begins > interesting when one considers this configuration : > the PC->the DSL box->the screen > since most of the ISP´s DSL box are more than a modem/router. By "more than a modem/router", do you mean "have multiple Ethernet ports", or something else? Certainly, if you have a DSL modem with some variety of hub/switch/router built-in, you could plug the screen into the DSL hub rather than into the computer. Assuming the DSL modem has a built-in firewall that you trust. > As well one can foreseen that the next generation of TV will have far > more logic inside, more capacities to handle graphics or codec, and > maybe not so different than a terminal. Any current TV that has a tuner for OTA digital will be able to decode whatever codec is used for OTA. (here OTA uses mpeg2ts) Whether there is a way to feed such a TV mpeg2ts data via a path other than the RF input is another question. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
