Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
Delay apparatus for a digitally encoded video signal, characterized by the combination of: means (24) for presenting for processing a first and second one of a plurality of digital input samples from said digitally encoded video signal, said digital input samples each having an encoded amplitude value comprising one of a plurality of possible values, said second digital input sample being displaced from said first sample; means (40) for generating first and second fractional sample coefficients and means (42.43,44) for processing said first and second digital input samples in response to said first and second fractional sample coefficients, said first and second fractional sample coefficients forming a unity fractional complement, and means (30,31,32,33,40,41,52) for combining said processed first and second digital input samples to form a third sample having an apparent predetermined displacement from said first and second digital input samples.
Claim 2
Dependent Claim
141 words
Delay apparatus for a digitally encoded video signal, characterized by the combination of: means (24) for presenting for processing a first and second one of a plurality of digital input samples from said digitally encoded video signal, said digital input samples each having an encoded amplitude value comprising one of a plurality of possible values, said second digital input sample being displaced from said first sample; means (40) for generating first and second fractional sample coefficients and means (42.43,44) for processing said first and second digital input samples in response to said first and second fractional sample coefficients, said first and second fractional sample coefficients forming a unity fractional complement, and means (30,31,32,33,40,41,52) for combining said processed first and second digital input samples to form a third sample having an apparent predetermined displacement from said first and second digital input samples.
Claim 3
Dependent Claim
19 words
Apparatus as claimed in claim 1, including means (30,40) for selectively choosing said first and second fractional sample coefficients.
Claim 4
Dependent Claim
26 words
Apparatus as claimed in claim 1, wherein said first and second fractional sample coefficients provide amplitude weighting of said first and second digital input samples, respectively.
Claim 5
Dependent Claim
