Abstract
Abstract A remote control receiver for processing signals representative of a desired television channel number, each channel number being identified by a control signal lying in a respective band of frequencies. The channel number representative control signals are supplied to a multi-stage counter which is also supplied with regularly recurring timing or clock signals. The clock signals determine counting intervals during which the number of cycles of the received control signal are counted. The counter is arranged to provide frequency divided output signals having binary digits which correspond to a binary coded representation of the channel number.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
In a remote control receiver for receiving control signals representative of a plurality of numerical quantities, each numerical quantity being identified by control signals lying in a respective band of frequencies, the combination comprising: means for supplying timing reference signals recurring at predetermined time intervals; and counter means responsive to said timing reference signals and to said control signals for providing binary output signals representing an accumulated count, said counter means including means for offsetting the count represented by said binary output signals in a predetermined manner so that digits thereof correspond to a binary coded representation of each received numerical quantity.
Claim 2
Dependent Claim
102 words
In a remote control receiver for receiving control signals representative of a plurality of numerical quantities, each numerical quantity being identified by control signals lying in a respective band of frequencies, the combination comprising: means for supplying timing reference signals recurring at predetermined time intervals; and counter means responsive to said timing reference signals and to said control signals for providing binary output signals representing an accumulated count, said counter means including means for offsetting the count represented by said binary output signals in a predetermined manner so that digits thereof correspond to a binary coded representation of each received numerical quantity.
Claim 3
Dependent Claim
39 words
In a remote control receiver, the combination according to claim 1 wherein: said counter means provides binary output signals of which the four least significant digits correspond directly to the binary coded decimal representation of each received numerical quantity.
Claim 4
Dependent Claim
41 words
In a remote control receiver, the combination according to claim 1 wherein: said counter means provides binary output signals of which the four least significant digits correspond to the complement of the binary coded decimal representation of each received numerical quantity.
Claim 5
Dependent Claim
57 words
In a remote control receiver, the combination according to claim 1 wherein: said counter means comprises first and second counters coupled together and means for resetting at least said second counter during each said time interval to offset the output thereof in a predetermined manner to correspond to a binary coded representation of each received numerical quantity.
Claim 6
Dependent Claim
38 words
In a remote control receiver, the combination according to claim 4 wherein: saiid resetting means is arranged to reset said first and second counters to zero upon counting of a predetermmined lower count limit during each time interval.
Claim 7
Dependent Claim
34 words
In a remote control receiver, the combination according to claim 4 wherein: said resetting means is arranged to reset said second counter to a non-zero condition prior to the start of each time interval.
Claim 8
Dependent Claim
24 words
In a remote control receiver, the combination according to claim 6 wherein: said condition corresponds to a one in the least significant digit position.
Claim 9
Dependent Claim
38 words
In a remote control receiver, the combination according to claim 7 wherein: said counter means provides binary output signals of which the four least significant digits correspond directly to the binary coded decimal representation of the numerical quantity.
Claim 10
Dependent Claim
26 words
In a remote control receiver, the combination according to claim 6 wherein: said condition corresponds to ones in each of the three least significant digit positions.
Claim 11
Dependent Claim
40 words
In a remote control receiver, the combination according to claim 9 wherein: said counter means provides binary output signals of which the four least significant digits correspond to the complement of the binary coded decimal representation of the numerical quantity.
