Solid state television channel selection system

A sequential and parallel access television channel tuning system comprising:

• a matrix array of channel selection switches each operable to provide parallel selection of a television channel,
• up and down channel selection switches operable to provide sequential selection of television channels,
• said up and down switches connected to terminals of said matrix array,
• means responsive to operation of said matrix array switches for generating unique parallel binary address signals corresponding to the selected television channel,
• means connected to said matrix array and responsive to operation of said up and down switches for generating sequential changes in said parallel binary address signals corresponding to sequential television channels,
• means responsive to said binary address signals for tuning a selected television channel, to remove
• means for generating a skip signal when designated ones of said binary address signals are generated, and
• means for applying said skip signal through said matrix array to cause the television channel to be skipped during sequential selection.

A television channel tuning system comprising:

• a programmable random access memory for storing predetermined digital tuning words,
• means for generating binary address words for addressing said memory,
• an up/down counter.
• means for applying the addressed tuning words from said memory to said up/down counter,
• a synchronous binary counter,
• means for comparing the outputs of said up/down counter and said synchronous binary counter for generating a digital tuning signal having a duty cycle representative of a desired television signal, and
• means for converting said digital tuning signal into an analog signal for performing television channel tuning.

A system for tuning a broadcast receiver comprising:

• an address generator for generating on a multiline output bus any one of a repertiore of multibit digital addresses each selectively associated with a broadcast channel desired to be tuned by said receiver,
• a plurality of switch means each operable to apply to said address generator an electrical indication to cause said generator to produce on said bus a unique one of said addresses associated with said switch means presently operated,
• a programmable tuning memory receiving said multibit digital address from said bus, said memory having at least one storage location uniquely designated by each multibit address received from said bus, each said storage location having stored therein and outputting when addressed a multibit digital tuning word and a digital band selection word,
• means receiving said digital tuning word output from said memory and converting said digital tuning word to an analog tuning level signal,
• means receiving said analog tuning level signal and said digital band selection word output from said memory and in response thereto adjusting said broadcast receiver for the reception of the broadcast channel selectably associated with said address presently appearing on said bus,
• means operable to electronically alter said digital words stored in any of said address locations in said tuning memory thereby to arbitrarily associate a selected broadcast channel with a given one of said storage locations and said address uniquely associated therewith, and
• a display means receiving said multibit digital address from said bus and visually indicating in response thereto the broadcast channel associated with said address.

A system for tuning a broadcast receiver comprising:

• an address generator generating on a multiline output bus any one of a repertoire of multibit digital address words each selectably designative of a broadcast channel receivable by said broadcast receiver,
• serial access switch means operable during activation to cause said address generator to sequence through its repertoire of addresses and periodically generate a different multibit address on said multibit line,
• a display means receiving said multibit digital address from said bus and visually indicating in response thereto the broadcast channel presently designated by said address,
• a programmable tuning memory receiving said multibit digital address from said bus, said memory having at least one storage location uniquely designated by each different multibit address received from said bus, each storage location having stored therein and outputting when addressed a multibit digital tuning word and a digital band selection word,
• means receiving said digital tuning word output from said memory and converting said digital tuning word to an analog tuning level signal.
• means receiving said analog tuning signal and said digital band selection word output from said memory and in response thereto adjusting said broadcast receiver for reception of the broadcast channel selectably associated with said address, and
• means operable to electronically alter said digital words stored at any of said address locations in said tuning memory thereby to arbitrarily associate a selected broadcast channel with a given one of said addresses.
