摘要： An optical return-to-zero (RZ) signal generator and related methods are described in which a phase modulator causes a phase change in an optical signal responsive to a transition in a driving signal, and in which an interferometer receives the optical signal from the phase modulator and generates an optical pulse responsive to that phase change. Preferably, the interferometer introduces a fixed, unmodulated time delay between its two signal paths, the fixed time delay being selected such that destructive interference occurs at an output of the interferometer when the phase of the optical signal received from the phase modulator remains constant. However, when a rising or falling edge of the driving signal causes phases changes in the optical signal, the destructive interference at the output of the interferometer is disturbed, and an optical pulse is generated. The driving signal is a differentially encoded version of an input information signal. Alternatively, the driving signal is proportional to the input information signal and the transmitted RZ-formatted optical signal is a differentially encoded version of that signal. Features for regulating the fixed time delay, features for frequency shift compensation, features for loss compensation/equalization, and integrated single-chip and multiple-chip embodiments are also described.

摘要： The present invention is a system and method that facilitates the reduction of presentation glitches in a digital video system. The present invention is a system and method that automatically determines if digital video (DV) data is missing from a stream of DV information and replaces or patches missing DV data with appropriate information to reduce the appearance of interruptions in the video (e.g., glitches in presentations). A communication packet carrying application data is received by an application data patching computer system. In one embodiment of the present invention, an IEEE standard 1394 compliant isochronous packet carrying digital video information is received. The application data (e.g., DV information) is separated from other communication packet protocol data (e.g., IEEE standard 1394 compliant header information). The received application data is analyzed to determine if it conforms to configuration constraints of predetermined application data format requirements. In one exemplary implementation, the initial information included in the application data section of the communication packet is analyzed to determine if it appropriately (e.g., sequentially) follows the information in previously received communication packet in accordance with predefined configuration definitions. If the information does not appropriately (e.g., sequentially) follow the information in previously received communication packet, a data patch is provided for lost or missing application data.

摘要： A system for packet parsing and data reconstruction in an IEEE 1394-1995 serial bus network includes a network interface unit, a processing unit, and a memory wherein an operating system resides. The operating system includes a streaming services module and a multimedia Application Program Interface (API) module. The network interface unit receives a stream of packets from a transmission device. Each packet includes a header portion, and may also include a data portion. The data portion, if present, stores data content generated from source data organized in accordance with a predetermined format. The streaming services module stores and then parses the received packets. A method for packet parsing and data reconstruction includes the steps of receiving a packet stream; storing a first and a second packet; locating a header portion within the first packet; and determining whether a header portion within the second packet immediately follows the header portion within the first packet. The method may also include the steps of determining whether the first packet corresponds to a particular boundary within the source data, such as the beginning of a digital video (DV) frame; and transferring data content within the first packet to a buffer.
