Abstract: A configurable document server is described. In some embodiments, the configurable document server can enable administrators to set an option that prevents documents from being routed to users when the configurable document server experiences some types of errors. When the configurable document server determines that such an error condition exists, it may prevent the routing of the corresponding document. By preventing documents causing errors from being routed, the configurable document server enables administrators to improve the accuracy of document workflow and thereby improve productivity of users.

Abstract: A system for reducing the bandwidth of a data stream transmitted via a digital multimedia link does not result in the loss of data. The system encodes control signals such that control words are generated each time the status of the control signals change. The system multiplexes payload data and the control words to generate the data stream. If no blanking period of the payload data is present, the data stream comprises payload data. During the blanking period, the data stream comprises the control words. The data stream is transmitted across the digital multimedia link using transmit and receive FIFO memories. The transmitted data stream is then demultiplexed, and the payload data and the control words are separated from each other. The control words are decoded to recover the control signals. The system can transmit payload data conforming to the video formats VGA, SVGA, XGA, SXGA and UXGA.

Abstract: An apparatus for serial transmission of data over a transmission path in a vehicle uses spread-spectrum modulation to enhance the electromagnetic compatibility with other electrical and electronic components in the vehicle. The apparatus includes a transmitter that subjects a clock signal having a predetermined frequency and phase to spread-spectrum modulation by wobbling a first clock signal within a predetermined frequency range. The serial data signal is transmitted synchronously with the wobbled first clock signal. The apparatus includes a receiver that uses a blind-oversampling clock and data retrieving unit (CDR unit) to receive the serial data signal. The receiver also generates multiple second clock signals. The CDR unit uses a predetermined algorithm to output the best-suited one of several oversampled serial data signals synchronously with a selected one of the second clock signals.

Abstract: A system synthesizes a remote controlled clock across data transmission through a digital multimedia link. A clock is generated at the receiver side that is exactly synchronous to a master clock at the transmitter side. The system includes a clock encoder on the transmitter side, a synchronous serial data transmission system, and a clock decoder on the receiver side. The clock encoder and decoder include counters that count up until predetermined numbers are exceeded and wrap around when those predetermined numbers are exceeded. A clock synthesizer in the clock decoder generates the remote controlled clock. A controller in the clock decoder processes remote and local time stamps and generates control signals that control the clock synthesizer such that the remote controlled clock has the same frequency and the same number of transitions as the master clock received by the clock encoder.
