Title: Innovations by Kumar Satyanarayana Hebbalalu
Introduction
Kumar Satyanarayana Hebbalalu is a notable inventor based in San Jose, California. He has made significant contributions to the field of data recovery in television signals. With a total of two patents to his name, his work has advanced the technology used in processing encoded data.
Latest Patents
Kumar's latest patents include innovative methods for recovering data encoded in television signals. The first patent focuses on recovering closed captioning and teletext data by over-sampling a line encoding the data. This method examines the resulting samples to determine the average number of samples spanning low and high values during a run-in period. By utilizing these averages, the sampling clock is determined, and errors caused by factors such as ghosting can be eliminated.
The second patent involves processing multiple streams of data encoded in respective Vertical Blanking Interval (VBI) channels using a shared equalizer. This circuit allows for the recovery of data from several VBI channels without the need for a large number of gates. An analog to digital converter (ADC) oversamples each VBI channel, while a clock and data recovery circuit identifies which subset of the oversampled data represents the encoded information. The selected subset is stored in shared memory, and the equalizer processes these samples to perform tasks such as deghosting, thereby minimizing the number of required gates.
