Abstract: In a method of forming a device so as to include a reflective surface at a specific angle to an incident optical axis, a region of a first major surface of a substrate is exposed to an anisotropic etchant to form a surface having the specific angle with respect to the first major surface, but the etched surface is then used as a mounting surface. That is, rather than anisotropically etching a reflective surface, the etching provides the mounting surface and the second major surface of the substrate functions as the reflective surface when the fabricated device is properly mounted. The substrate may be a <100> silicon wafer having a 9.74 degree off-axis cut. Then, a 45 degree mirror is formed by the process. When the reflector is used in an optical device, the <111> crystalline plane will be generally parallel to the surface of the support.

Abstract: A file format design supports storage of multi-source multimedia presentations via the inclusion of indications as to whether a presentation is a multi-source presentation, and for one media type, the tracks of which are from different sources and should be played simultaneously. If a multi-source presentation exists, additional indications may be provided including: an indication of a multi-source presentation type being stored; indications regarding the source of each track and which tracks have the same source; indications of different parties' information such as phone numbers, etc. Thus, a player may play back a recorded presentation in the same or substantially the same manner as it was presented during the actual session, and may automatically manipulate the presentation to be more informative or efficient. The file format design further supports storage of other types of multi-source presentations that render more than one media stream for at least one type of media.

Abstract: Systems and methods are provided for signaling the decoding order of ADUs to enable efficient recovery of the decoding order of ADUs when session multiplexing is in use. A decoding order recovery process in a receiver is improved when session multiplexing is in use.

First information associated with a first media sample to identify a second media sample is signaled upon packetization to indicate/aid in recovering. Upon de-packetizing, a decoding order of the first media sample and the second media sample is determined based on the received signaling of the first information.
