There are child locks and channel locks available in present day TV's. If you want to know how they work, it is like this. There are resonant circuits for each freqency in the band width of the TV. You add up or subtract either the resistance or the capacitiance of the rc tuned circuit. Adding up to block and subtracting to activate the channel.

You can set up a software firewall that will block ports. ZoneAlarm is one of the most popular.  Below is a link to PcWorld.com where you can review a short description of ZoneAlarm and several other free firewalls.

Is it possible that your parents put a block on the TV on certain networks, ratings or programs.  Or is this an on-line problem.  Could be that you're trying to view a site that charges.

I think u have a Firewall thats blocking you from broadcasting. Many Private Networks have these features enabled

Connect an antenna to the back of the TV where you would connect the cable TV, and on the settings or menu of your TV, set it up so the TV picks up local AIR instead of cable TV.  Reception will be poor and will sort of betray the idea of spending extra $$ for an LCD

build an electromagnetic pulse generator - that will destroy all of the electronics that they own. that would quiet things down.

Use firewall and specify a port on internet connection to be blocked.\nIf you are using a router, you can configure it to block or allow certain port to the internet too.

Not sure about that but you could try sopcast. It might not show sky tv broadcasts but whenever there are sports events (soccer/F1/cricket), someone starts broadcasting it. If you have good bandwidth, its a great tool

You can't completely.  The best you can do is take advantage of all the technology that exists.  Make sure your controlling what is on tv, what is on the computer, and what is in your home.  In the outside world though you have little control and need to explain it to your kids.

THere are certainly several products out there that can do this. I just had a chance to play with "SlingBox" and it worked very well.\n\nhttp://www.slingmedia.com/indexa.php

You should try local stores like Radio Shack. Maybe ebay is cheaper but make sure they would work on your tv and not just some gadget that they say work. \nhttp://www.buymebuyme.com/retail/customer/product.php?productid=44975&partner=g&gclid=CKP4r5n5xIQCFQtTCwodtCW9Kw\nhttp://www.dropamp.com/
