No, the idea of distributing Pay Television by encrypted terrestrial broadcast became popular in the 1970s (channels such as SuperTV, Wometco Home Theater, Prism, Preview, SelecTV and ON-TV) but all of these stopped broadcasting long before the digital transition and there are no such channels left.
Encoders turn readable information into a different format for example a CD track into an MP3. A decoder undoes this encoding to make the file readable, for example windows media player (it also does encoding). Or a television station compressing data into encoded format for broadcast on the digital broadcast network, and a sky box which decodes the information for display.
Since 1995
Electromagnetic radiation (radio waves, light) travels in free space. This radiation can be encoded to carry either analog information or digital information. An example of analog-encoded radiation is that emitted by an AM radio station. Examples of digitally-encoded radiation are a wireless home computer network and the next generation of television broadcasting.
Neither a DVD nor a CD would be affected by magnetic fields, because the information is digitally encoded using optical media.

House, or House M.D. is a television drama series. Though it has eight total seasons, only the first seven of the eight seasons have been encoded onto a DVD.
The way in which the information is encoded is the difference between a digital and an analog television signal. Traditional television signals are prone to fading, ghost images, and static. A digital television signal produces a crystal-clear picture and sound without fading or interference.
The suffix in the word encoded is -ed.
The suffix for encoded is "-ed".
Television remote controls use light to communicate with televisions. Infra-red light is invisible to the human eye but it is a very effective way of sending data across a short distance. To send a message, the light is sent in a pattern of flashes. When the pattern is received by the television and decoded, it will become a number or perhaps a pair of numbers that the television will use to do a specific task. Every button on the remote has a different number value that is encoded into a string of flashes. Different remote controls use a wide range of different encoded patterns so remotes for one item of equipment won't interfere with other units.
The past tense of "encode" is "encoded."
PAL is the color encoding method used in Europe and other parts of the world. North America, Japan and other countries use NTSC. Although the two encoding methods are similar, the signals are not compatible. A third color standard used by France is SECAM. SECAM is used in a handful of other countries but is not a common standard. PAL and SECAM encoded signals are normally used at 50Hz while NTSC normally uses 59.94Hz. There are some rare exceptions to these field rates but it is normally safe to assume that 50Hz material will be PAL encoded and 59.94Hz will be NTSC encoded.
