System and method of patching missing digital video packets communicated in an IEEE 1394 compliant implementation

A missing application data patching method comprising the steps of:

• a) receiving a communication packet carrying application data;
• b) separating application data from other communication packet protocol data;
• c) analyzing received application data to determine if it complies with expected predefined data configuration;
• d) providing a data patch for lost or missing application data including sequential values based upon video frame information, wherein said sequential values are calculated based upon a previous video frame and said sequential values include the current frame and wherein said data patch includes performing an appropriate sequential DIF patch if section type (SCT), a DIF sequence number (Desq) and a DIF block number (DBN) are missing;
• and
• e) forwarding application data and patch data for further processing.

A digital video computer system comprising:

• a means for communicating information;
• a means for capturing video information associated with an image and a sound, said means for capturing video information coupled to said means for communicating information;
• a means for processing information to determine if said video information is not received and providing patch video information, patching said missing video information including performing an appropriate sequential DIF patch if section type (SCT), a DIF sequence number (Desq) and a DIF block number (DBN) are missing including sequential values based upon video frame information, wherein said sequential values are calculated based upon a previous video frame, said means for processing information and patching missing video information coupled to said means for communicating information;
• a means for displaying said image, said means for displaying said image coupled to said means for communicating information;
• and
• a means for transmitting said sound, said means for transmitting said sound coupled to said means for communicating information.
