Latest Patents
One of Okatani's latest patents involves a method of reproducing video information in a disk player. This method includes techniques for preventing noise output to a television monitor during unusual conditions in a disk player. For instance, when the disk player is reproducing information from a composite disk that contains both audio and video, and a search is conducted that requires the pickup to cross a boundary between the two regions, the most recently reproduced video information is stored in a video memory. This information is then repeatedly read and displayed on the television monitor during the search process.
Another innovative method developed by Okatani addresses the detection of an off condition of the main power supply. When this condition is detected, the most recently read video information is stored in a video memory and is continuously read out until the disk player is reinitialized. Additionally, the last known address of the pickup before the power interruption is stored, allowing the pickup to return to that location and resume playback without requiring the user to conduct an additional search.
