Abstract
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 trans…
