Television broadcasts are now almost exclusively digital. Video, audio and other information are broadcast as a single data stream so there is no requirement nor an option to split the signals.
In the days of analog broadcasting, the audio signal was commonly broadcast as a separate signal using a related transmission frequency.

Do TVs work without cable?
Yes, an HD television will operate without an HD cable box. Many will now receive HD signals using a built in tuner and will receive SD signals using the tuner as well. If an HD television is purchased before an upgrade to an HD cable box, the television will accept SD signals from the existing cable box. The quality will still be SD - there is no increase in the resolution just because the television is HD. When an HD box is obtained, the television will be ready to display HD signals.
Where you can find a parabolic antenna to catch TV shows from Tokyo to Romania?
Broadcasts intended for an audience in Japan are not available in Europe. If they are terrestrial broadcasts, the transmission power and earth's curvature will prevent the signal reaching Europe. Satellite transmissions are focussed on a certain area, known as the signal footprint. Once again, those signals will not be available in Europe.
How satellite pictures of earth are made and transmitted?
Satellite pictures of Earth are taken by a camera mounted on a satellite in orbit, high above Earth's atmosphere. They are transmitted wirelessly over satellite signals, much like satellite TV.
How do TV satellite receivers work?
Tv signals are a type of wave form. They bounce from the source, to a satellite in space, down to your dish. Then the receiver box translates the wave into the sound and pictures you see.
Do newer televisions need dish or cable?
No, newer TVs do not need dish or cable, at least not in the US. There may be instances where someone living in a remote locale cannot get any "regular" broadcasts from stations in the area, but most people live in a place where TV signals are still broadcast in a "conventional" way from a local station. There is an issue in that the new regulations have allowed broadcasters to go to a "digital" format, and you'll need a converter if your "newer" TV isn't capable of handling that new TV modulation scheme. Dish or cable is an option for TV viewers, and the issue centers on whether an individual wants to watch one or a few local broadcasts for free, or wants to watch a whole stream of broadcasting that is only available from a provider who carries all those signals for a price. That's what dish and cable are all about; they offer large numbers of stations and different packages or "groups" of signals to appeal to the family, the sports enthusiast, or the film aficionado. The more you want to watch, the more it costs to get those signals.
