| 217805 | 2004-02-24 04:47:00 | Hi I hate the channel logos on TV, variously described as Bugs. Dogs or Watermarks. Sky, Prime and TV3 are the main culprits. I'm looking for a tool that will allow me to obliterate them before they reach my TV / Video. Pure Motion's EditStudio has a good knockout feature that does the job but does not deal with streaming video. I really want to capture the signal, get rid of the logo and send the clean signal to the TV. Anybody know of anything ? Cheers Andy |

| 217808 | 2004-02-24 11:52:00 | There is software to remove the logo after you have saved it to a harddrive, but I don't know of any that allows you to do it as you stream it. The TV stations are going to have to do something about their logos as many people are finding that their 6000 to 10,000 or more Plasma Televisions are suffering from the old problem of Burn in, as the logo's stay in one place all the time, ESPN and CNN are amongst the worst and so even when the TV is turned off the logo is still visible. |

| 217809 | 2004-02-24 17:42:00 | Logo visible even when the TV is turned off . . . . ? I didn't think that was possible . Please would someone who understands such electronics explain HOW to someone who finds the more she learns, the more she discovers she doesn't know . (I need hardly say I'd like the easy version, please . And if there's no easy version, I can live without knowing this . . . . . ) |

| 217810 | 2004-02-24 19:13:00 | Having worked in TV for a while, I have seen these "bugs / watermarks" come into existence. These bugs are put on the signal as the last thing to leave the station to the transmitter. As yet I do not know a way to remove them, although if you used a DPM (digital picture manipulator) you could zoom the picture and move it until the bug is no longer visible. This is a rather expensive option. Most of the bugs today are a light grey with transparent elements in them. As the bugs are only on during programme segments, which are at the most 8 minutes long on commercial stations, burn in is not really an issue. I have worked in stations where monitors have had bugs on them all the time. Burn in happens only after years of constant signals does burn in occur. Laura, burn in can leave a ghostly image of the bug imprinted on the picture tube so that when the TV is turned off the image remains on the screen. PS: I hate them too |

| 217811 | 2004-02-24 20:15:00 | It's always interesting that the TV networks ignore the views who ***** and moan about these logos but they never put them on buring the ads. Why?? Because the aversisers ***** and moan and the networks take notice of them. Screw the viewer though.. | paulw (1826) | ||
| 217812 | 2004-02-24 21:27:00 | Though the end result is the same, the mechanisms are different for CRTs and plasma screens . CRTs use an electron beam to excite phosphors, which then fluoresce to create light . A static image will slowly burn the phosphor, creating a darkened area in the form of the average (static) image size and shape . You see old monochrome monitors in secondhand shops (and in some business premises still) that have the layout of the most commonly used screens imprinted on the phosphor . Sometimes you can even read the screen heading . Plasma screens use technology the emits light under electrical stimulation rather than an electron beam . These screens have a finite life (in 1000's of hours) and if a group of pixels are constantly on they use up their life earlier and become darker . The logo will then show on other programming, especially light scenes, as a darkened area in the shape of the logo because of the reduced light output . It may also show when the screen is off if the pixels change colour slightly as they age . LCDs do not seem to suffer from this effect as they simply control the transfer of luminance from a backlight through liquid crystal pixels that vary their light transmission to produce the image .

| 217813 | 2004-02-24 22:16:00 | I quite like them - at least I know which channel I am watching. They all seem to broadcast the same crap these days so we really only need one channel. ;\ ;\ |
