Spectrum cable subscribers still watching cable television without a set-top box will soon need one, or a functional equivalent, for every television connected in their home or business as Charter Communications continues its effort to encrypt all cable channels.

The campaign has now reached Kentucky, where Spectrum is preparing to encrypt every television channel on the lineup and is sending notices to its residential and commercial customers.

The University of Kentucky is working to get the word out to facilities operated by UK they may lose all television service as early as July 11 if they don’t take action.

Encryption forces customers to use set-top boxes or other equipment, often at an additional expense, to continue watching cable television service. Cable companies use encryption to reduce signal theft and eliminate the need to send trucks to disconnect customers at the pole. Instead, Charter will simply deauthorize a customer’s set-top box or other equipment so they can no longer watch when the customer cancels or does not pay their bill.
