Conditional methods to digital television and access device to simultaneously handle multiple TV programs.

摘要

television receiver system comprising: - a plurality of television receivers mechanisms for receiving a plurality of television program signals separated to produce a plurality of input signal streams; - a multiplexer mechanism coupled receptor mechanisms television to mark only every flow input signals and multiplexing the streams input signals marked in a single combined signal stream, - a security mechanism receiving the combined signal stream and sensitive access control of the single combined signal stream and producing a signal flow combined with access allowed; - a mechanism demultiplexer coupled to the security mechanism for receiving the signal flow combined with allowed access and detect only specific marker for each stream of input signals, which demultiplexes the single stream of combined signals with allowed access in each signal stream input access allowed by respective marker, restore the initial marker on each input signal flow permitted access, and produce television program signals corresponding to each separate flow input signals received by receiving mechanisms; - circuitry responsive to at least one of signal flow input permitted access to supply image signals to a television display mechanism to produce television images allow.
