You're free to dispute all you want Bob, it's 480i and it's a composite video out.
Today, that's the lowest resolution available in the word of video.
That's a simple fact.
As to the quality, here's a little bit of a read:
Technically speaking, component can produce 480i, but composite can only produce up to NTSC. 480i is a component video standard. It has to do with the color space that component can generate, but composite cannot. We use these terms loosely because NTSC really doesn't describe the resolution.
Pro: Single video cable. Can be used with an RF modulator
Con: Compromises with color and luminance artifacts and reduced luminance and color resolution
Not so short story:
The problem with composite video is separating the chroma and the luminance signals. This can result in crosstalk between the two signals which creates artifacts, and can decrease resolution. Chroma leaking into the luminance can appear as a crawl effect going from bottom to top (NTSC). Luminance leaking into chroma appears as rainbow patterns or flicker on diagonal edges. The NTSC color separation technique has improved over the years. A simple frequency filter was first used (1D), then adaptive line combs became common (2D) and then adaptive frame combs became popular (3D). Each improvement allowed decreased artifacts and better resolution. However, keeping the two separate is still a better approach. In areas that use NTSC, two methods are commonly used for analog video: S Video and component. RGB is another option, but is not very common for consumer video connectivity.
However, just as the modulation and demodulation of RF loses quality, the mixing of the various signals into the original composite signal does the same, causing a checkerboard video artifact known as dot crawl. Dot crawl is an infamous defect that results from crosstalk due to the intermodulation of the chrominance and luminance components of the signal. This is usually seen when chrominance is transmitted with a high bandwidth, and its spectrum reaches into the band of the luminance frequencies. This has led to a proliferation of systems such as S-Video and component video to maintain the signals separately. Comb filters are also commonly used to separate signals, and eliminate artifacts, from composite sources.
If it's the TV, then my new Sharp Aquos 32 inch is also "not working properly", my Toshiba 42 inch Plasma is "not working properly" and my 26 inch Samsung is "not working properly" as they both have the same issue as the 32" Toshiba that came with the trailer when it's hooked up to the ZX700.
Oddly enough, all these sets "work properly" when tested with a DVD player (480i setting and 480p settings) through the same composite out on the DVD player and composite in on the sets.
In fact, the only tv "working properly" with the zx700 is the cheapy Konka small screen that came with the trailer for the bedroom. The only reason I can see for this is the Konka doesn't have to process the signal as much to scale it to the smaller size screen (or "native resolution" if you prefer).
The only TV I have that I haven't dragged out the trailer is my older Sony Wega CRT tv. That's not going to happen either, that sucker has to weigh upwards of 80 pounds! It's quite happy in the upstairs room where it is!
As it stands, it appears the issue is the TV's are just working too hard to process the 480i signal in resolution and scaling.
That says to me that the problem is the ZX700 and not the TV's I have used with it.
If you have concrete info that shows this is not the fact, I would welcome you to post it and rebutt my speculations.
I will continue to experiment, speculate and post findings until the solution (or more acurate info) is put forth from the manufacturer or I find a resolution myself. It's a free world and an open forum after all...
No need to take it personal, I'm just looking for the solution. I'm not saying Concertone isn't working on a resolution to the issue, and I sure will be ordering up "a solution" when/if it comes out.
I'm just not going to "take it on faith" that a solution is comming given the lack of any real info on what the problem is. I've been filibustered before to be "just out of warranty period" and I keep my eyes wide open now.
Let me be clear here, I'm not saying you or Concertone is doing that (run out the warranty) or have intention of doing that, but I am a very wary consumer after being "burnt" before.
However, after it's all said and done, I am very curious to see if it's going to be an "up converting" box or something else all-together.
I do love a good problem to chew on though.....
