PUBLISHER'S LETTER V-chip is a sign of a weak society So the politicians have decided that all new TV sets should have V-chips installed. Announced during July as one of the measures in a crackdown on TV and video violence, this must be one of the silliest decisions made by the new Federal government. There is no doubt that we do have a big problem with violence in our society but putting V-chips in TV sets won’t have any effect at all. So how would it work? The V-chip is supposed to sense the presence of violence in the program and stop it being shown on the screen, if the set has been programmed for this action. Just how does the V-chip know that the program contains violence? Because the video signal has a particular code, similar to a Teletext signal, inserted during the blanking intervals. And who puts the codes in? Why the program producers or the TV stations or the video duplicators, that’s who. In other words, there will be a major censorship applied to all programs. Of course, we don’t know how far this violence censorship will go. Will violence be censored from cartoons? Will the Road Runner no longer be able to obliterate the Coyote? After all, it’s pretty violent stuff, isn’t it? And what about TV news? Apart from all the effort which would need to be made to code all programs, the parents must also program their new TV set so that it doesn’t show violence to their kiddies. If you think about how inept most people are when it comes to programming their VCR, and how most children can do it without thinking at age seven, then the possibility of children reprogramming V-chipped sets to show anything is highly likely. But in any case, how long would it take before all the old TV sets without V-chips disappeared from Australian homes? 20 years? 25 years? More than enough for an entire generation to be unaffected by the V-chip measure. No, the V-chip idea is just stupid. At one time, there would have been no argument, in most homes, about whether children could watch a particular program or not? Mum or Dad used the big knob on the front of the set to turn it off! No high technology there. And if the kids gave any backchat they would get a clip over the ear. Oh, I’m sorry, that’s violence, isn’t it? Really, if this idea is to be taken seriously, then most adults have to be classed as incapable of taking responsibility for raising children. Maybe that’s the solution. Maybe people should be “chipped” to stop them having children if they are classed as likely to be incompetent parents. Seem like a silly idea? It’s not as silly as the V-chip.
