Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
37 words
A method of data recovery for data packets transmitted within specified time intervals comprising the steps of : determining clock corrections while data is being received during one interval; and extrapolating said corrections to the next interval.
Claim 2
Dependent Claim
35 words
A method of data recovery as recited in claim 1 in which said determining is by: scaling the clock corrections for the portion of the interval during which data is transmitted to the entire interval.
Claim 3
Dependent Claim
21 words
A method of data recovery as recited in claim 1 in which said determining is by using a look up table.
Claim 4
Dependent Claim
21 words
A method of data recovery as recited in claim 2 in which said determining is by using a look up table.
