摘要:
This disclosure generally relates to stereoscopic images and stereoscopic video signals, and more specifically relates to encoding, distributing, and decoding stereoscopic images and stereoscopic video signals for use in television and high definition television systems, teleconferencing, picture phones, computer video transmission, digital cinema, as well as in other applications that include storage and/or transmission, over any suitable medium, of still or moving stereoscopic images, or combinations of moving and still stereoscopic images, in a form that is compatible with existing infrastructure, without requiring additional system functionality, while providing a means to allow higher resolution images to be distributed while maintaining compatibility with the existing infrastructure. The techniques hereof can be employed, for example, for distributing stereo 3D movies via optical disk, satellite, broadcast, cable, or internet, using current infrastructure, to consumers.
摘要:
A transport stream decoder/demultiplexer is provided which includes a program clock recovery circuit for recovering a program clock from program clock reference (PCR) values contained in selected transport packets. A processor is provided for extracting elementary stream data from transport packets labeled with packet identification codes (PIDs) that are specified by a host processor. The processor separately stores the elementary stream data of each stream. A host processor interface is also provided for transferring data between an external host processor and the program clock recovery circuit. A memory manager may be provided for storing the data extracted by the processor for each elementary stream in a corresponding queue. The queues may be maintained by the memory manager in an external RAM. A descrambler interface may be provided for transferring scrambled data and data derived from conditional access information between the processor and an external descrambler. In addition, at least one elementary stream interface, such as a video interface or audio interface, may be provided for outputting extracted elementary stream data for a particular elementary stream from a corresponding queue. Furthermore, a high speed interface may be provided for outputting transport packet data prior to data extraction by the processor.

A lamp memory module is provided for recording lamp serial numbers, providing a ‘lamp-inserted’ interlock for preventing operation of the lamp when the lamp is not properly installed, and for collecting and storing lamp operational data such as lamp use (time), lamp strikes and various system temperatures.
摘要:
A safety interlock system for a projector system is provided. The projector system has a lamp, a controller and ballast for powering the lamp upon receipt of a lamp enable signal from the controller. The projector system further has a safety inter-lock system for deactivating the lamp in the event the lamp is not properly installed.
