I imagine that the encoding scheme is probably difficult to break without having the specifications and schema and they can’t Google it from several or more light years away.

Analog encoding is difficult too. We on Earth are shielded from signals more than a few hundred miles away by the curvature of the Earth, so the same frequency is used for different programs by stations a few hundred miles apart. But the hypothetical aliens would have a hard time picking up anything but noise because they would get all the TV transmissions from the world mixed together and interfering with each other.

In the extremely unlikely case that extraterrestrials are close enough to receive human television, why would they bother? Most television is drivel.
Television transmitters are designed to send signals out in horizontal directions and not up into space, that would waste power. So signals reaching space could be fairly weak. In addition several programs are transmitted on the same channels, which further complicates things. But if a single signal was clear enough, any aliens with the technology to receive weak signals from several light years distance would probably have the technology to break the coding.
At present in some counties digital and analog versions of the same signal are going out so it might be possible to decode the digital ones if you know what the end result should be.
Lots of humans don't watch television because they choose not to do so. Can't see why aliens would bother. It would bore or disgust them, mostly.

There will still always be sattelite TV, which Aliens will syphon the signal to learn about Earth secrets from, and watch a classic Alien invasion movie.

it's no easier nor harder. Analog signals require a complex system to decode the hetrodyne and phased elements and to know what they mean.
Digital requires undestanding the compression algorithm.

The UFO's will absorb your electricals and the aliens have telepathic so they can hear you next to your bed when you are sleeping.
