Can you Split cable with different channels?

If you are spliting your own cable in your own home, electronic supply stores sell a cable spliter. If you split the signal too many times, it degrades, and you will have to contact the cable company to have your signal boosted. However, depending on the provider, you may be charged for additional connections. Service from basic cable is controlled by the tuner of your TV or cable box. Spliting a signal after a digital tuner will produce the same channel on every TV after the split.
