The television further comprises a programmable conditional access system to enable conditional access to the premium television services received by the at least one television signal interface from the at least two different service providers. ## Claims ### Claim 1 An apparatus comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising: storing first conditional access and digital rights management data at a programmable memory for a first television service; decoding one of a demodulated cable signal, a demodulated satellite signal, or a demodulated over-the-air signal to generate a first decoded signal according to a first television service that is enabled by the first conditional access and digital rights management data; presenting the first decoded signal at a display according to a channel selection; receiving second conditional access and digital rights management data from equipment associated with a second television service; and storing the second conditional access and digital rights management data at the programmable memory to enable the second television service and to disable the first television service. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the second conditional access and digital rights management data that is stored in the programmable memory is accessible to the processor when the programmable memory is removed from the apparatus. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the operations further comprise detecting a first modulation type of an input signal. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the operations further comprise demodulating, via a single demodulating unit, the input signal to generate the one of the demodulated cable signal, the demodulated satellite signal, or the demodulated over-the-air signal. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the operations further comprise reading, from the programmable memory, the first conditional access and digital rights management data associated with the first television service. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the cable demodulator comprises a quadrature amplitude modulation demodulator. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the satellite demodulator comprises a quaternary phase shift keying demodulator. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the programmable memory is removable. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the first decoded signal comprises a moving picture experts group-2 encoding. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the first conditional access and digital rights management data is overwritten at the programmable memory. ### Claim 11 A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, comprising: storing first conditional access and digital rights management data at a programmable memory for a first television service; decoding one of a demodulated cable signal, a demodulated satellite signal, or a demodulated over-the-air signal to generate a first decoded signal according to a first television service that is enabled by the first conditional access and digital rights management data; presenting the first decoded signal at a display according to a channel selection; receiving second conditional access and digital rights management data from equipment associated with a second television service; and storing the second conditional access and digital rights management data at the programmable memory to enable the second television service and to disable the first television service. ### Claim 12 (depends on 11) The non-transitory machine-readable storage medium of claim 11, wherein the second conditional access and digital rights management data that is stored in the programmable memory is accessible to the processor when the programmable memory is removed from an apparatus. ### Claim 13 (depends on 11) The non-transitory machine-readable storage medium of claim 11, wherein the operations further comprise detecting a first modulation type of an input signal. ### Claim 14 (depends on 13) The non-transitory machine-readable storage medium of claim 13, wherein the operations further comprise demodulating, via a single demodulating unit, the input signal to generate the one of the demodulated cable signal, the demodulated satellite signal, or the demodulated over-the-air signal. ### Claim 15 (depends on 11) The non-transitory machine-readable storage medium of claim 11, wherein the operations further comprise reading, from the programmable memory, the first conditional access and digital rights management data associated with the first television service. ### Claim 16 (depends on 11) The non-transitory machine-readable storage medium of claim 11, wherein the operations further comprise demodulating a first premium television signal by quadrature amplitude modulation demodulation. ### Claim 17 A digital television device, comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: storing first conditional access and digital rights management data at a programmable memory for a first television service; generating a first decoded signal from one of a demodulated cable signal, a demodulated satellite signal, or a demodulated over-the-air signal according to a first television service enabled by the first conditional access and digital rights management data a decoder; storing second conditional access and digital rights management data at the programmable memory to enable second premium television services and to disable first premium television services; receiving second conditional access and digital rights management data from equipment associated with a second television service; and storing the second conditional access and digital rights management data at the programmable memory to enable the second television service and to disable the first television service. ### Claim 18 (depends on 17) The digital television device of claim 17, wherein the operations further comprise selecting a cable demodulation, a satellite demodulation or an over-the-air demodulation to demodulate a television signal according to a first modulated type of the television signal. ### Claim 19 (depends on 18) The digital television device of claim 18, further comprising reading, from the programmable memory, the first conditional access and digital rights management data associated with the first television service. ### Claim 20 (depends on 17) The digital television device of claim 17, wherein the second conditional access and digital rights management data that is stored in the programmable memory is accessible to the processor when the programmable memory is removed from the digital television device.
