Latest Patents
One of his latest patents is a method and apparatus for reproducing video signals at a selected speed. This invention involves a magnetic tape video playback apparatus that regenerates the sample rate from playback to operate a counter. It detects video data block numbers, allowing an address generator to derive the more significant bits of addresses for a picture memory where the video data signal is temporarily stored. The counter provides the less significant bits of the write addresses. Additionally, separated vertical sync pulses are counted in a second counter to provide time information for storage in a time data memory, which operates in parallel with the picture memory. A reference sample rate generator operates a third counter that provides the read-out addresses for both the picture and time data memories. The memory input and output time data are compared, and the time difference is evaluated against a threshold to provide an error flag to an error concealment unit. This unit conceals errors resulting from overage video data stored during high-speed playback. At low speeds, the minimum time difference designates an error.
Another significant patent is an intermediate picture field storage system for slow-motion playback. This system utilizes four picture field memories, with three available for writing and only one in read-out operation at any time. An AND correlation of a write flag and an error flag is necessary for providing an error recognition signal to subsequent circuits. The correlated signal is used to rewrite the error flag in the error flag memory, ensuring that any error flags are transmitted and rewritten while all write flags remain erased.
