If you want to access your TV channels over your computer, connect a Slingbox device to your Comcast cable box. The Slingbox device uses an infrared transmitter to change the channels on your cable receiver in the same way that your remote control changes channels. The Slingbox then connects to your home internet router so you can access the Slingbox through your home network. With the Slingbox software installed on your computer, you can then watch your Comcast cable programming on your computer from any location that has Internet access. Writer Bio
