Thanks Doug. Can you suggest a discount source for that TV? Does it have
option to run on 120vac too? -- Eliminate "ns" for email address. "doug dotson" wrote in message ... We have a Sharp 12V 10.5 LCD TV in our V-Berth. Works great! Has a remote, also you can mount it upsidedown and can program it to invert the image. Cable ready and we also have it connected to our DVD via direct video inputs. Doug s/v Callista "Len Krauss" wrote in message ... Thanks Al. I was afraid there might be such problems. Another thing that could work for me, on the boat of course, is 12vdc/120vac small-LCD-screen flat panel TV, cable ready. I've seen ads for one or two, but know nothing about them. If you or someone else can commnet pro or con, would appreciate it. Thanks. -- Eliminate "ns" for email address. I tried the ATI TV Wonder(plugs into USB) with my HP notebook with XP and couldn't get it to run right, kept crashing, so I took it back. I have also been casually looking, but haven't seen anything XP certified yet. Al "Len Krauss" wrote in message ... Can anyone recommend a USB connected external TV Tuner, cable ready, with remote control for use with WinXP notebook PC? Or not recommend, if there's one to steer clear of. Thanks. |

The Sharps come as 12 vdc but also have a wall wart for 110vac..

small-LCD-screen flat panel TV, cable ready.
A much better option. The screen is optimized for a TV signal, and has a much wider viewing angle. Some boat friends of mine went the laptop TV card route, and were endlessly fighting over whose head got to occupy the "sweet spot" in terms of viewing angle. I have a Samsung 150mp and am very happy with it. Very electronically quiet, doesn't foul up HF reception. Magnetically inert too. The speakers are kinda tinny sounding, but a $10 set of computer speakers produces "theater sound." Unlike a laptop there's no power hungry Intel CPU, hard drives, etc.; it consumes only 35 watts, compared to 80 watts for my laptop. Also doubles as a monitor via a 15 pin cable, but only 1024x768. Great way to play DVDs though. It'll run on clean 12.3 volts +-5%, but high voltages will burn out the flourescent tube system which lights the screen, because there's a stepup transformer for it which overheats at high voltages. So, you can get away running it on ship's 12 volts without a voltage convertor-stabilizer thingie ($150), but not while charging or running electrical equipment which introduces transients into your DC service wiring. Best is to run it on AC thru an invertor, if 35watts is in the high efficiency part of your invertor's power output curve. Only caveat is small "wide screen" HDTV flat panels are just around the corner, a normal aspect ratio flat screen TV is going to obsolesce fairly quickly. |

om... small-LCD-screen flat panel TV, cable ready.

Indeed. Always use a 'whatever in' to 12V converter. I was involved on a ship where 12 professional LCD touchscreens were installed. They were rated for 24V and directly connected to the 24V power system (=batteries). Within a few weeks, all monitor backlights failed. They couldn't stand the voltage of a full battery (27-28V).

I was concerned about overvoltage when we got ours. The specs
indicate a range of voltages that are accepted with the max up around 15V. Since this unit is made to be installed in RVs and vans etc, it is designed to handle varying voltages during charging, etc. If my battery bank needed equilization, I'd make sure it was disconnected.

USB resources in your computer are not fast enough to provide good
full motion video to your PC and its monitor. That requires direct memory access from the bus to the video card's memory, so the video card must be plugged into one of your bus ports. I've been using the Hauppauge WinTV card, here, for many years. It's fully cable-ready and provides a dithered, high resolution analog picture that doesn't suck up any system resources or slow down my older 733 Mhz computer you can notice. Even USB 2.0 is too slow, and even if you did get it working, you'd have no other USB devices to use because it would suck up all the system resources trying to keep up with the picture and the intense data necessary for it.

Provided the video is sufficiently compressed, enough bandwidth on the USB bus can be allocated for streaming video in TV quality. Even USB 2.0 is too slow, No. USB 2.0 is 480Mbit/s while the FireWire bus, which is suitable for top-notch studio quality is "only" 400Mbit/s Regards, Meindert |

Whoa, Sport! All you say is oh-so-true.....BUT THE DAMNED COMPUTER
ISN'T A CRAY! If you're jamming up the motherboard with ALL THAT VIDEO DATA, it's slower than hell while that's going on..... Now, if you plug in a bus TV card with DirectX access to the video memory that DOESN'T hog the computer resources with all this video BS, it uses no computer resouces you can detect. If you think an external USB TV plugged into the NOTEBOOKS they're talking about is gonna work great.....you must come from another planet! Hell, notebooks are ALREADY bogged down. They're running WinXP! On Fri, 12 Dec 2003 16:06:18 +0100, "Meindert Sprang" wrote: "Larry W4CSC" wrote in message ...

Mmmm, I can run a video clip on my rather slow computer (450MHz). The clip is 352 x 288 pixels and runs at 25 frames/second. That is almost comparable to normal TV. And we've run some DirectX experiments here which gave full TV resolution at over 100 frames/sec on a 700 MHz AMD. Now, if you plug in a bus TV card with DirectX access to the video memory that DOESN'T hog the computer resources with all this video BS, it uses no computer resouces you can detect. Oh I agree. I have run two framegrabbers simultaneously in one computer and four wouldn't have been a problem too. If you think an external USB TV plugged into the NOTEBOOKS they're talking about is gonna work great.....you must come from another planet! Hell, notebooks are ALREADY bogged down. They're running WinXP! I think the average notebook today is much faster than my computer here :-) Meindert On Fri, 12 Dec 2003 16:06:18 +0100, "Meindert Sprang" wrote: "Larry W4CSC" wrote in message ...

No. USB 2.0 is 480Mbit/s while the FireWire bus, Well, USB 1.0 is too slow, full screen was kinda blocky and bad sound sync. |
