    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.

    摘要: A remultiplexer is disclosed for communicating plural programs. Each program comprises one or more elementary streams that are encoded in relation to a single common time base corresponding to the respective program. The communicated programs originate from plural input transport streams that each comprises plural transport packets. Each transport packet contains a packet identifier indicating the data contained therein. Within each transport stream, unique packet identifiers are assigned to each elementary stream of each program. The data of each elementary stream is only contained in transport packets having a corresponding packet identifier. Each input transport stream contains time stamps for reconstructing the single program time base corresponding to each program conveyed therein. The remultiplexer has a data link module which receives the plural input transport streams. The data link module also selectively extracts transport packets from the received input transport streams. The remultiplexer has a downstream bus on which the data link module sequentially transfers at least some of the extracted transport packets. The remultiplexer selects which of the extracted transport packets to transfer on the downstream message bus depending on the packet identifiers of the transport packets. The remultiplexer also has a scheduler which assembles the transport packets transferred on the downstream bus into a single output transport stream.

    摘要: A TDMA communication system (100) comprises a two-way subscriber unit (112') and at least two base stations (104b and 104c). The subscriber unit monitors the strengths of signals (114') received from the base stations. As the subscriber unit roams within the area serviced by the communication system, the received signal strength will vary as the subscriber unit moves nearer to or farther from the base station that is transmitting the call. When the subscriber unit moves out of the range of the base station, the subscriber unit determines, based on certain predetermined criteria, with which base station to communicate.

    摘要: An apparatus for printing graphics images on plastic cards comprises a computer, a graphics printer connected to the computer, and control means executing on the computer for supplying graphic images to said graphics printer. The control means parse commands from an input data stream by identifying a delimiter preceding each command. The control means create images to be printed on the plastic card in response to the commands. The control means combine the images into a composite image and supply the composite image to the graphics printer.

    摘要: Analog-to-digital converters are subject to errors including the known half least significant bit quantization error and also bit weighting errors due to lack of an ideal binary relationship between the transition points of all the bits. The known statistical average error reduction method in which a relatively small dither component is added to the analog input signal can only fractionally reduce overall error and has little effect on bit weighting errors. Herein the analog signal is added to a dither signal, for example a ramp signal, which varies through half the peak to peak digitization range of the converter so that irrespective of the input signal all output signal bits, other than the most significant bit, are "on" for one half of the sampling period. The result is that all the less significant bit errors are cancelled leaving only the easily compensated most significant bit error. A random component can be added to the dither signal to reduce the quantization error.

    摘要: Disclosed is a telescoping pole connected to a sealing attachment that has two sealing caps, each having a tubular aperture. The sealing caps fit over the water intake ports of an outboard or a sterndrive marine motor, creating an enclosed compartment through which water can be pumped into the marine engine and outdrive. A hose runs down along the length of the telescoping pole and connects to one of the sealing caps so that water can be pumped through the hose into the engine. The present invention has connection means for both the telescoping pole and the hose on both sides of the sealing attachment, allowing the present invention to be used regardless of which side of the boat the dock is positioned on.
