Abstract: A layered glass structure includes an inner layer having opposing major surfaces. The inner layer includes a first glass powder and a first inorganic filler. The inner layer has a first coefficient of thermal expansion (CTE) and a first transition temperature (Tg). An outer layer is disposed on each opposing major surface of the inner layer. The outer layer includes a second glass powder and a second inorganic filler. The outer layer has a second CTE and a second Tg. A CTE gap between the first CTE and the second CTE is between 10×10?7/° C. and 30×10?7/° C. A difference between the first Tg and the second Tg is 10° C. or less.

Abstract: A method of producing a glass structure includes forming a green body having an inner layer of a first powder of a first glass composition in a first organic material matrix and an outer layer of a second powder of a second glass composition in a second organic material matrix, the outer layer covering at least two opposing major surfaces or all surfaces of the inner layer, the first glass composition being different from the second glass composition, the first and second powders having respective first and second sintering temperatures, the second sintering temperature being within 0 to 30° C. of the first sintering temperature; and debinding and sintering the green body to remove the organic materials and to sinter together the first and second glass powders to produce a sintered glass structure having an inner layer of the first glass composition and an outer layer of the second glass composition.

Abstract: A method of encrypting a motion picture file and a method of digital rights management using the same, wherein encryption method includes: extracting information on the location of at least one video sample, which is a real-time streaming unit, from meta-data of the motion picture file; extracting the video samples based on the location information; encrypting the extracted video samples, excluding a start code within a video sample header of each extracted video sample, based on predetermined encryption information; and producing an encrypted motion picture file by recombining the encrypted video samples. Since the file is encrypted in units of video object planes (VOPs) while maintaining an MEPG-4 file format, the encryption method can be easily applied to a completed file format and streaming service is also possible.
