How To Turn a Computer Monitor Into a TV
How To Turn a Computer Monitor Into a TV
A computer monitor works the same as a television monitor, whether it's a tube or LCD model. So any old computer monitor can easily be turned into a TV. If your old set died, your old PC monitor can replace it. If you have an LCD computer monitor, you can have your own LCD TV for a lot less money. You just need to make sure the monitor can connect to your cable or satellite receiver. If the monitor has the same video connection ports your TV source uses, you're good to go. Otherwise, you need a tuner box with a VGA connection port.
Instructions
Directions
1
Check the monitor to see if it has an S-video, component or any other connection port besides the standard VGA computer port. If it has any ports that match with your cable/satellite box's output ports, connect the two devices using a working cable.
2
Connect the cable or satellite receiver to an external TV tuner if the receiver can't connect directly to the monitor. Use an S-video connection if a port is available on both devices. RF coaxial or RCA composite cables are your likely other options.
3.Attach external speakers to the TV tuner or cable satellite box if the monitor doesn't have speakers of its own. Connect the speakers to the video box's audio output using RCA composite cables. You only need audio cables with red and white plugs.
4
Add extra peripherals like your DVD player or game console. Connect the extra devices to any available input ports that match up. You will likely need the external tuner for this unless the cable box has multiple input ports.
5
Attach the monitor to the external TV tuner. This requires a VGA connection, which is the same cable used to connect the monitor to a desktop computer. The plug attaches to a trapezoid-like port and is secured by twisting pins on each side.
6
Turn the cable/satellite box and monitor on. Select the correct source on the tuner box with its remote control. Use the cable box's remote to change channels.

Instructions
1
Click "Start" and select "All Programs."
2
Click "Windows Media Center" from the list of programs. The Windows Media Center window opens.
3.Scroll to "TV" on the start screen and select it. Click "Live TV" to begin watching the current digital TV programming. Click "Guide" to view current and future digital TV listings. Navigate the guide and select the TV program you want to watch.

How to Make an Analog PC TV Tuner Work After the Switch
How to Make an Analog PC TV Tuner Work After the Switch
If you have an analog TV tuner connected to your computer, you most likely have realized it no longer works now that all television broadcasts are digital. However, this does not mean you can no longer use your analog TV converter. You just need to treat the tuner as an analog television. An analog television can still view TV programming as long as a converter box is connected to it.
Instructions
1
Connect the source of the TV signal to the "In" port on the converter box. This can be an antenna or cable outlet. If you access your television programming via cable or satellite receiver, you do not need a converter box and can connect the receiver directly to the TV tuner.
2
Plug a coaxial cable into the "Out" port on the converter box. Make sure the cable is properly attached to the port to ensure a secure connection.
3.Run the other end of the cable to your PC TV tuner and connect it to the video port.
4
Power on the converter box. Open the software you have installed on your computer that allows you to view TV. The signal travels from your antenna or cable through the converter box and into the analog TV tuner on your computer. You can now continue browsing and using the computer as a TV, just as you had before the switch to digital.

How Does a Digital Satellite Receiver Work?
Encryption
Just like cable TV, satellite TV can only be availed through paid subscription. Since TV signals transmitted via satellite are indiscriminately broadcast on a large area, these signals need to be encrypted so that only subscribers are able to view the shows and programs on the hundreds of channels that are offered by a satellite TV service. Inside each digital satellite receiver is a chip that can unlock and decode the signal. The security measure that this chip performs is unique for each satellite TV service provider. Thus non-subscribers who may have their own satellite dishes and digital receivers are unable to watch the shows on their television sets, even though they may physically pick up the signal.
Compression
A TV signal contains a huge amount of information. It would take enormous power and a very wide frequency range to transmit and broadcast video and audio data as it is viewed and heard by human audiences. Therefore, compression is necessary to make the whole process efficient. Digital satellite TV signals are commonly condensed into MPEG-2 or MPEG-4 format. These are the same compression formats used to effectively transfer or stream multimedia content on the World Wide Web. A digital satellite receiver takes this compressed digital TV signal and converts it into an analog format that a typical television set can output. With newer television sets that are designed to take in digital signals, conversion is no longer necessary.
Tuning
TV signals are radio waves and radio waves are modulated in order to be able to carry information. Older and more common ways of modulating radio waves are amplitude modulation (AM) and frequency modulation (FM), and these are the two ways of tuning in on radio. For satellite television the modulation standard is known as Digital Video Broadcasting or DVB-S. The "S" stands for "satellite" and distinguishes this method from the modulation standard used by cable television, which is denoted as DVB-C. Satellite TV service providers use a technique called multiplexing to mix and cram together several channels into a single transmission. When this single transmission reaches the subscriber, the digital satellite receiver extracts individual channels and feeds it to the television set.

Other Features
Aside from the basic function of processing a satellite TV signal, digital satellite receivers may have other features built into them by their manufacturers. One popular feature is the capacity to record digital video. Recording television shows is possible through an internal hard disk much like that of a personal computer. The show is written and stored in the digital satellite receiver's hard disk and can then be viewed at a later time.

How to Record Satellite TV Programs Into a DVB-T Digibox
How to Record Satellite TV Programs Into a DVB-T Digibox
The DVB-T Digibox is a powerful satellite receiver unit that can be used in conjunction with a satellite TV provider to give access to satellite TV programming. Many home TV viewers encounter the problem of wanting to watch a program that is airing when they are away from their TV. Rather than miss the program altogether, many choose to record the program and save a copy of it on their satellite receiver's internal hard drive for future viewing. This is called digital video recording (DVR), and you can use it on your Digibox DVB-T receiver in just a few simple steps.
Instructions
1
Contact your satellite provider and see if your Digibox DVB-T is DVR-capable. If it is not, you will first need to upgrade to a different receiver that does support DVR recording. If compatibility is not an issue, however, you are ready to proceed.
2
Add DVR service to your satellite account if you do not have it already. This will most likely involve an extra service charge on your monthly service rate.
3
Verify that the service has been added to your account by attempting to record the program you are currently watching. If the program records without error, press "Stop" and call up the recording to make sure it plays back with no issues. If it does, you are ready to continue using DVR service with your Digibox satellite receiver.
