Re: Video On Demand pixeling nofios, typically it is the signal from the ONT that is running too hot. Often +18 to +20db. The attenuators should be being placed on the coax coming from the ONT, into the splitter. The optimal signal for FiOS is in the -2 /+ 4 db range, so if you start with +18, add a 4 way splitter that looses 7 db, you still have +11 at each port on the splitter, so you would need to add a 9db attenuator to bring it down to +2, which is in the acceptable range.
This is as simple as I can explain it. The condition, or length of the coax runs add additional losses that have to be factored in too, but short runs of 30' or less of good quality RG6 with the proper compression fittings, should not cause any effect on signal reliability. | |
| The signal at the ONT does come in +18 - +20db, and the attenuation is generally put on the input of the splitter, db ranges VZ uses is anywhere from -6db - +5db for the digital channels, and 0db - +11 db on the analog channels. If one of the legs has problems, sometimes they will put amplifiers on the line, but generally as a last resort (replacing the line being the best option).
The problem in this post seems to be on the internet side of things which is still transmitted to the STB via the Coax only at a higher frequency on MOCA. This doesn't seem to be the issue either, ON demand anything is only as good as the copy that the provider has at their end, ie if they have a bad spot in their copy, obviously no matter what you do on your end, you won't be able to get rid of that bad spot on your end. Try to rewind to the bad spot and play that again, and if it is still there, it is the content being delivered from HBO. | |
