Robust interactive communication without FEC or re-transmission

摘要

The present invention provides a method for robust interactive multimedia communications without the necessity of forward error correction or re-transmission. Video data is transmitted in the form of spatial packets known as I-frames and temporal packets known as motion vectors and associated prediction errors. The I-frames are inversely coded and stored and utilized as a basis for the motion vectors until a new I-frame is successfully inversely coded. Likewise, the motion vectors are also stored and used to produce P-frames until a new set of motion vectors is successfully transmitted.
