Comcast is a cable television service provider in the United States. Many Comcast customers receive cable descrambler boxes as part of their cable package. These cable descrambler boxes feature a Comcast-branded universal remote control you can use to control connected audio and video devices. Dynex manufactures and markets a line of flat-screen televisions, and if you have a Dynex television, you can program your Comcast-branded universal remote control to operate the television.
