<p>A system for packet parsing and data reconstruction in an IEEE 1394-1995 serial bus network includes a network interface unit (120), a processing unit, and a memory wherein an operating system resides. The operating system includes a streaming services module (150) and a multimedia Application Program Interface (API) module (170). 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 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 DV frame; and transferring data content within the first packet to a buffer.</p> |
