You can imagine, what headache is to make back link: they need special transmitter on decoder - so they also need some diplexer on decoder to avoid interference; next, they need to add back channel amplifiers on every cable amplifier - as result they need to add some directional splitters and simple diplexers on every in and out of every amplifier. Next, they need to avoid collisions from back signal from different decoders.
And also they need to add receiving system on the end. Really they need also a big money to teach staff that will make service on that network.
But on real system they avoid that all. They simply send some messages on that special tv line. These messages are like that: "Decoder - Stop your receiving and go to lock state", or "Decoder - Unlock and receive channels 1,2,3,4,7,8,9". So, as you see, every decoder has unique name. Also there is unique name for whole network to avoid migration of decoders to other networks.
So, when decoder is locked, it is configured to receive one "main" channel, but do not show TV picture on tv-set. This decoder is staying on locked mode on that tv channel untill it will receive permittion signal to unlock and receive certain channels. Also there are coming blocking messages. All these messages are repeated all the time with minutes period. There are few methods to c rack this system : 1. To make indipendent decoder.
To change firmware on decoder. To intercept digital data in input of decoder processor and withdraw blocking messages. So, as tv-provider knows that subscriber can decode channels by these methods, then provider tries to make it more difficult. They add special blocking RF-filters on network. All TV spectra is divided on few bands : Let say channels 49MHzMHz - is "basic plan" for subscribers, channels - is "extended plan" - is "primary plan". Ok, if subcriber is receiving only basic plan then they add some blocking rf-filter that will stop all signals upper than MHz That is why : 1.
See the files: us Your explanation sounds reasonable except the part about RF filters. I have checked and they do organize the channels into limited groups. However, channels in each group are all over the frequency spectrum!
Therefore a simple RF filter will not work. In my country, the provider has two-way communication as the network is cable modem ready. Although I believe that may be another frequency band. I have a rocky television. I bought an antenna from Walmart nothing. What can I do to get some kind of channels without paying for it.
Struggling mother just needs to be able to watch the news and weather at least. Unfortunately, not everyone will be in a location that gets good reception using an antenna.
A clear line of sight to the outside makes for the best reception. Most of the HD TV antennas are directional so they need to be pointed in the direction of the towers.
There is a website that you put in your ZIP code and it will tell you what direction to point the antenna and how far away the towers are. It will also tell you what channels you should get. I pick up about 80 channels here in AZ. You could try a digital converter box. Then use remote that comes with converter box to scan for channels. I tore down my dish from the side of my house and made a planter out of it.
Then unplugged everything from my older flat screen TV. Been two years without cable of any kind. Occasionally move antenna and rescan. Must say however I did eventually invest in one of those 30 dollar flat antennas you put in the window to get better reception and I got it. Never used it because we had cable. Just moved and cable is too expensive, so I thought about the paperclip and then remembered I had the rabbit ears.
The U-shaped clips had been stripped off, so I was able to twist the exposed wires to create a single input wire and stick it into the cable hole of our flat-screen kitchen TV. Thank you, Beth! I just tried this hack on my TV and it picked up over 40 channels but there is no picture or sound.
I get a square box in the middle of the TV that says Audio Only on some channels. I have re-scanned for channels several times but get the same result. I also tried hooking the tv up to an antenna but all I got was no-signal. I have the right antenna, researched where the broadcast tower is and best antenna for my location but no -signal.
I have moved the antenna and tv to other locations in the house but still no signal. I even tried the antenna with a different tv but still got no signal.
What is frustrating about this is I live in an area that is slight hilly. I am at a higher elevation than these two neighbors and I get no signal. My cable bill just went up There has to be a way cut the cable cord once and for all.
It could be a combination of things like the TV, the direction you face, the distance from the towers, the makeup of your home which blocks the signal, etc. I have read the article on how to get free T. Can you help me to get this going. I would love to stick it to the cable companies who like to charge an arm and leg for there so called service.
The best way would be to do a search for your TV model number and add manual at the end. All fine and dandy until the cable company does a tap audit and decides to come after you for cable theft.
I get it cable is expensive, but so is the infrastructure that delivers the service. And leeching on the infrastructure can actually degrade the quality of service for paying subscribers. Not worth it folks. Trust me. This is in my own home that I do technically pay for, although my television decodes additional channels in-between the normal stations.
You need to find the manual for your particular television and look up how to manually scan for channels using the cable not the antenna option. Skip to content.

Reply to Paul. Appreciate the response Paul. While the cable company can file a civil lawsuit for "signal theft", they will likely not file a lawsuit unless they are confident that they can demonstrate that the box was used illegally. If a cable company files a lawsuit, under U. The attorney fee award may well be larger than the amount found owing for unpaid cable fees.
