Abstract: An optical storage system achieves high density, sufficiently high to permit both video and audio to be stored on a compact disc, or to store other data at very high density. Pits are encoded on the disc storage medium with respect to timed electronic reference signals (not simultaneously optically encoded on the disc) which divide each revolution of the disc into a multiplicity of equal spaces or references. The pits have leading edges on the leading side of a reference signal and trailing edges on a trailing side of the reference signal, so that each pit staddles a reference signal. The length of the pit leading up to the reference signal represents one sample of information, while the length of the pit from the reference signal to the pit's trailing edge represents another sample of information. In this manner high density is achieved at high accuracy and low noise, since one end of each bit of information is precisely located and readable without the lesser precision involved in determining the location of the leading and trailing edges of the pit in reading the information. On the disc the reference signal frequency is generated during the vertical retrace interval(s), encoded by equally spaced pits, for correlation with the prevailing speed of revolution of the disc. At each horizontal picture line (e.g., 525 per revolution) there is at least one reference pit. When this is detected the amount of phase shift which may exist at that line is measured and corrected for. Two samples of the video waveform are reproduced and measured for each pit. Small compact video discs can be produced with inner diameters of 2" to 4", or video bandwidths of up to 10 MHz can be produced for high resolution pictures.

Abstract: Primary colors red, green and blue are each transmitted in three adjacent frequencies to create stereoscopic 3D images. A true center frequency for each primary color is transmitted to one eye while two straddling frequencies, on either side of the center frequency, are transmitted to the other eye. Untinted, notch filtered stereoscopic 3D eyeglasses may be used to segregate light frequencies and direct one channel to each eye of the viewer. A new dual channel laser illumination projection engine may be used to homogenize, condense, combine, and polarize light from red, blue and green lasers to create stereoscopic images suitable for projection on either white of sliver screens.

Abstract: An auto chroma filter averages the value of successive color burst amplitudes on a line-by-line basis over many video frames, by fetching a burst value from memory and loading it into an up/down counter, and also into a D/A converter which provides the chroma filter output signal. A comparator compares an incoming new burst value with the output signal, whereby the counter increments or decrements the value toward the incoming new burst value in response to the comparator. The updated value then is loaded back into memory in the same location from which it was fetched, and the cycle continues for each video line and successive frames.

Abstract: In one aspect the plasma lamp according to the present invention comprises a gas envelope that is constructed from ceramic material and a sapphire window rather than quartz. According to another aspect of the present invention, a plasma lamp comprises an RF structure for the radio wave radiation and an envelope for housing the excitation gas that are formed so as to constitute a single, integrated ceramic structure. According to yet another aspect of the present invention, the plasma lamp comprises a waveguide structure having solid material such as ceramic rather than air for the dielectric and a gas housing made of a combination of solid ceramic and a sapphire window. In this way, the separate quartz gas envelope and air-filled waveguide structure employed in the prior art are replaced by a single, integrated structure.
