Latest Patents
Tim Callahan holds a patent for a "Delay stabilization method and apparatus for video format conversion." This patent outlines a method for stabilizing delay during the conversion between Standard Definition (SD) video and High Definition (HD) video. The process involves establishing an integer divide ratio (M/N) that corresponds to the clock rates of the output and input formats. By generating the output clock rate from the input clock rate using a Phase Lock Loop, a known phase relationship between the two clock rates is maintained at a repetitive interval. This allows for the video frame to be transferred at a known repetitive interval, providing coarse control over the input-to-output video delay. Additionally, a fine-tuning control (delay block) is included to accommodate any programmable delay in video throughput with an accuracy of ±0.5 output pixel periods.
