Converting video connection types

post #1 of 19
Thread Starter 
After reading the above comments on s-video....and that s-video connection would have "superior" video quality (as in the case for the Channel Master CM7000) over composite...

However according to Wiki, S-video is not suitable for hd signals...so what gives?

"Due to a lack of bandwidth, S-Video connections are generally not considered suitable for high-definition video signals. As a result, HD sources are generally connected to a monitor by way of analog component video or wideband digital methods (usually HDMI or DVI). However, on the older monitors with S-Video but without HDMI and DVI, some graphics cards have full display (including bootup display) with HDMI, DVI and S-Video and partial full display (displaying only after the OS boots up) with component and composite. So in this case, S-Video works well as it allows the user to see the display in the event that they need to adjust settings in the CMOS..."

"S-Video cables are used for computer-to-TV output for business or home usage. Because it is very simple to convert S-Video to composite signal (just the logical merging of the two through a filter capacitor is required), many electronics retailers offer converter adaptors for signal conversion. Conversion will not improve image quality, but will allow connecting to otherwise-incompatible devices. Converting composite signal to S-Video is harder, because once Luminance and Color are merged it is hard to separate them while minimizing loss. High quality comb filters are commonly used to separate the signals."

I'm thinking of getting a s-video adapter for the low loss composite Monster 2 video cable I got for the Zen DTT901 routed to my 30" Tantus EDTV...but after I read the above article, it makes me think twice...it could be for naught.

Nice setup, especially for a $40 converter!

The CECB's are not HD - they only put out 480i resolution.

S-video is superior to composite and RF for an SD, 480i signal.

Rammitinski, I plan on getting composite-to-s-video adapter for the video cable input. So by using it, would it yield a better picture vs plain rca composite?

How about a composite-to-Y, Pb, Pr adapter...is there such a device? I was looking for one in Monoprice..but it seems that they don't carry that.

I know it's kinda off topic but can anyone knowledgeable please help out..

Do some looking at www.svideo.com - you might find something.

No. Unless you spend a lot of money, the only use for a composite to S-Video converter is to manage the connector type. You can't get better video quality that way.

Forget about it. Same reason as above.

What you should really do for the best possible set up with your EDTV, is to ditch the Zenith, get an HDTV capable set top box, and use it in 480p output mode with component video (or DVI/HDMI). The converter boxes are significantly less capable for an EDTV.

Suggestions:
Right now, the Dish DTVPal DVR is shipping for about $280. It receives Digital TV with an antenna, just like the Zenith, records and stores all Digital TV formats, and has 480p output compatible with your EDTV.

If you want to spend less, the Samsung 260 is a Digital TV receiver and has 480p output compatible with your EDTV. It goes for about $170, and is the most popular current choice.

I'm with Ken - you really don't want to use one of the CECBs with that TV - you would be happier with a true HDTV capable tuner, such as the Samsung DTB-H260F, outputing through component video for 480P (or higher and let the TV downconvert it).

By the way, Monster Cable is typically way over priced. You can get comparable performance for a lot less $$$.

Thanks for the replies, guys. I think the Samsung 260 is the way to go...

I have several surplus Monsters from my old HT setup...just giving it a new lease on life for the Zen.

It is a good choice. Also some good bargains on used older HD STB's can be found on ebay.

If his TV is 4:3, hopefully it will have a zoom function of it's own, otherwise 4:3 material on an HD channel, if you want it in it's correct aspect ratio, will be postage-stamped. The only way to make it fill the screen with the H260F is to use the "tall & skinny" mode.
post #14 of 19
Right.
Also, for those considering the Samsung,the OSD does not work on when in SD output mode. So it does not make a good converter for tv's that can't handle component sources at 480p or higher.

Manufacturer's product description

Samsung TSK3092WF DynaFlat 30" Color Television is on of the best choices for borderless home TV and video experience. Providing the 16:9 Screen Aspect Ratio it is 480p EDTV Upgradeable with add-on DTV receiver / decoder that outputs 480p display. The system converts NTSC to 480p and dramatically improves any video source to 480p progressive picture quality with up to 800 Lines of Horizontal Resolution. The 2 Tuner (P&P) Picture-And-Picture mode is gradually becoming a standard for watching two programs at once side by side and this TV is equipped with it as well. Velocity Scan Modulation reduces blurring and ghosting for a picture with sharply defined edges and outlines, while 3D Y/C Digital Comb Filter constantly analyzes the three dimensions of picture height, picture width, and picture changes-over-time, to minimize edge image artifacts while improving transition detail. Invar Shadow Mask alloy material allows increased focus and brightness without sacrificing color purity, Multi Focus Electron Gun dramatically reduces deflection distortion and geometrically maintains sharp focused images and line details, Dark Tint Picture Tube minimizes reflections and improves colors and picture contrast. Dynamic Black Level Expansion and White Peak Limiter further improves picture contrast, Auto Kinetic Bias automatically regulates the white balance to maintain consistent, optimal performance even after many years of use. All that, plus a superior sound is what makes this television the best!

Sounds like you're good to go then.

Wow! I just rediscovered and realized the actual features of my Tantus edtv.

I'm now running the PIP feature of this tv. One half of the screen with component/Panasonic DVD-CP72 (progressive/Faroudja) "old school" dvd player playing and the other half on composites/Zen DTT-901 simultaneously (all Monster cables on both)...and the PQ, color and clarity on the OTA "hd" Zen are as vivid and sharp as the running 480p dvd on the progressive scan Panny, believe it or not.

According to Samsung, this TSK3092WF model upconverts any video signal (even NTSC) using the Pro-Chip feature to progressive 480p...Based on the comparison above, I'm a believer! It does seem to upconvert any video signal....including the downconverted 480i digital signal of the Zen DTT901 and up back to progressive.

Looks like I'll be skipping the Samsung 260 for now it seems...very happy with this setup right now.

p.s. Guess I'll keep using my 32LG30 for pc monitor duty till my crt Tantus goes bust...

Without getting technical, as good as your set is at upconverting, it won't look nearly as good as the HD tuner downconverting.

Get the Samsung 260. Trust me. Try one from a source that has a good return policy.

Initially, I was trying to order from CC online but is out of stock for sometime now...but since my Zen + "upconverting" Samsung EDTV setup works real good for my current needs...and that the Samsung 260 model, though a superb hd tuner no doubt but has some quirks, is nearly 2 yrs old...for now, I'd wait it out for the successor/improved model.
