Publication number: 20040047593Abstract: An adaptive clocking mechanism is provided for a digital display system. The digital display system includes a clock recovery system, for recovering a system time clock from a video bit-stream generated at an encoder, and a decoding system for decoding and decompressing the video bit-stream at a frame rate. The adaptive clocking mechanism operates to determine, from video format information transmitted from the encoder, the occurrence of a frame rate at which a transmitted signal is encoded that differs from a frame rate expected by the decoder. Upon such a determination, the adaptive clocking mechanism further operates to select a modifier from a group of modifiers based on format information derived from the video bit stream, including the encoded frame rate. The selected modifier is then applied to a synchronization function of the decoder in a manner to bring the decoder operation into synchronization with the non-expected encoder frame rate.Type: ApplicationFiled: September 5, 2003Publication date: March 11, 2004Applicant: Sony CorpInventor: Takaaki Ota

Patent number: 6490402Abstract: A flexible electronic color display includes a light-emitting diode (LED) matrix formed from an interweaved weft of conductive strands and warp of light-emitting diode (LED) fiber of a conductive core coated with a p-doped semiconductor and then an n-doped semiconductor of light-emitting polymer. Each conductive strand physically and electrically couples to each LED fiber at one location to form an LED that may activated as a pixel. Alternating LED fibers of different hues may provide a color display, especially for a relatively fine weave or for displays viewed from a distance. Alternatively, conductive strands and LED fibers may be selected having sufficient transparency that layers of multiple LED matrices, each having a selected hue, may form a color flexible display. In addition, methods for fabricating the LED matrix and for detecting and eliminating flaws from the LED matrix allow for economical manufacture.Type: GrantFiled: August 2, 2000Date of Patent: December 3, 2002Assignees: Sony Corporation, Sony Electronics Inc.Inventor: Takaaki Ota
