How does TVGuardian work?
TVGuardian uses a patented process invented by our founder to detect profanity and other offensive phrases, mute the audio and modify the broadcast closed captioned signal. The process consists of monitoring the closed captioned signal, each captioned word is checked against a dictionary of foul words stored in TVGuardian. If an inappropriate word or phrase is detected, the audio is muted, the offensive word is removed from the closed captioned signal, and a suitable word is substituted, when appropriate.

Why does TVGuardian mute the phrase instead of just the profane word?
TVGuardian's method of muting the offensive phrase is much more effective than just muting the profane word. If only a single word were muted, your eyes would still be focused on the mouth, making it easy to read lips and fill-in-the-blanks. Thus, muting only a single word would defeat the purpose of TVGuardian.

Does my TV need a closed-caption decoder for TVGuardian to work?
No. It doesn't matter what kind of TV you have or how old it is. TVGuardian has everything that it needs to filter out the foul language.

Is the closed-captioning displayed all the time?
Only if you want it to be. TVGuardian has three closed-caption settings. The normal setting will display modified, profanity-free closed-captioning only during the mute of offensive phrases. You can also set TVGuardian to not display any closed-captioning, or it can be set to display profanity-free closed-captioning during the entire program.

How do I connect TVGuardian?
TVGuardian easily connects between your VCR, Cable Box or Satellite Receiver and your TV. If you can connect a VCR to your TV, then you can connect TVGuardian. Normally, the cable, antenna, cable box or satellite receiver is connected to your VCR, your VCR is connected to TVGuardian and TVGuardian is connected to your TV. When your watching television, you will need to change channels with your VCR, cable box or satellite receiver. TVGuardian Manual

What inputs and outputs are available?
TVGuardian has Hi-Fi audio and Video RCA type inputs and outputs. A coaxial (RF) output is also included. TVGuardian Manual

How can I connect my DVD Player and VCR to TVGuardian?
To use TVGuardian with multiple devices without having to disconnect one to use the other, you will need to purchase an Audio/Video Switch Box. The allow you to switch between multiple sources (DVD Player, VCR, etc.) by pushing a button. An Audio/Video Switch Box can be found at Radio Shack and other electronics stores.

Does TVGuardian work with all TV Shows, Videos and DVDs?
TVGuardian works with virtually all TV shows, DVDs (see DVD info below) and videos, including videos you have recorded of qualified TV shows or movies (not home movies). Practically all TV series, TV movies, videos rentals and purchased videos will be filtered by TVGuardian. Some older programs do not have the required closed-captioning, but that is already changing. Most popular older movies have already been re-released with closed-captioning, and more are being re-released. The FCC is requiring 95% of all programs shown to be closed-captioned by 2002. TVGuardian will not work with live programs, such as news, sporting events and talk shows.

Does TVGuardian work with TV/VCR Combo units?
No it does not. TVGuardian must be able to intercept the programs and edit out the foul language before it reaches the TV. This is not possible with the TV/VCR Combo units.

Does it work with DVD Players?
Yes it does. We've tested dozens of DVD Players and all but two worked great. Although almost all DVD Players do work with TVGuardian, not all do. DVD Player models from RCA, GE, Sanyo, Toshiba, Panasonic, Denon, Pioneer, Sony, Philips have all worked. To be safe, a simple test can be done to make sure a DVD Player will work with TVGuardian. Ask the sales rep to turn the Television's closed-caption decoder on and play a DVD (something other than Universal Studios). If you see closed-captioning, TVGuardian will work with the tested DVD Player.

Does TVGuardian work with all DVD Movies?
TVGuardian works with all DVD Movies tested except those from Universal Studios. Luckily, Universal Studios only produces a small percentage of the available movies. Universal Studios does not provide the closed-captioning signal in the format standards used by the rest of the industry and outlined by the FCC.

Does it support HiFi Stereo and/or surround sound?
TVGuardian does support HiFi Stereo and ProLogic surround sound. It also works with DVD Players. However, it only supports Dolby Digital 5.1 if your DVD Player has a Dolby Digital 5.1 processor built-in. If it does, TVGuardian can be connected to the center speaker output of the DVD Player. Ninety-five percent of the voice track comes through the center channel. TVGuardian will mute the dialog when offensive language is detected, and the background audio will remain untouched.

Does TVG filter `god' when used as an expletive?
TVGuardian always attempts to filter `gd' in both filter settings. The Strict Filter Setting also filters the words God, Jesus and Christ when used as an expletive. Some programs have a religious theme. Therefore, TVGuardian's Moderate Filter Setting allows most uses of God, Jesus and Christ except for the obviously offensive uses.

What is the closed captioned signal?
The closed captioned signal is a hidden signal that is embedded in the video signal of most broadcast television and video tapes. It is intended for deaf and hard-of-hearing individuals. Closed-captioning service officially began in the early 1980's. On August 7, 1997, the FCC approved a new law which will mandate captioning on virtually all television programming in the United States. This mandate will be phased in over the coming years. However, today the closed captioned signal is in almost every new video release and major network broadcast. Again, TVGuardian reads this hidden signal to detect cuss words. Check out Gary Robson's CC FAQ for more information.

Why doesn't it detect every cuss word?
Since TVGuardian is dependent on the accuracy of the closed captioning to detect cuss words, it cannot know if a cuss word is spoken unless it is captioned. The closed captioned signal is more than 95% accurate on scripted, or pre-recorded programs. Therefore, TVGuardian is more than 95% accurate on these programs. However, it is not going to detect cuss words when the following occurs:

1. A cuss word is not captioned.
2. A cuss word is captioned, but it is not syncronized with the audio.
3. An unusual cuss word is used, and it is not in TVGuardian's dictionary.
4. The program is not closed captioned.
5. The program is a live broadcast, and the closed captioning is delayed.


How do I know if a movie is closed captioned?
You can normally expect any movie released since the mid-1980's to be closed-captioned. However, if you want to be sure. Look at the movie lable, or box. Some are captioned, yet don't contain a notice. However, most have ``Closed-Captioned", ``CC", or one of the following symbols:

This is a generic symbol which can be used by any company.

How is TVGuardian different from the V-Chip?
TVGuardian and the V-Chip are two very different parental control devices. The V-Chip is merely an automated on/off switch. It is based on a ratings system that is broadcast with the television signal. If a program's rating exceeds the allowed rating set by the parents, the V-Chip blocks the entire program. Since the V-Chip is based on the broadcast ratings system, it does not work on movies played on a VCR, Laser Disc Player, etc.

TVGuardian, on the other hand, fills a void left by the V-Chip. Most parents that don't want their children watching certain programs, simply don't let their children watch them. The problem is programs with content suitable for children, except for the language. TVGuardian solves this problem. In addition, it works on movies played on your own VCR.
