RECONSTRUCTION OF ERRORED MEDIA STREAMS IN A COMMUNICATION SYSTEM

摘要

A method for reconstructing and reproducing a received media stream while minimizing storage space is presented. The media stream transmitted by a transmitting device is uploaded to an external storage device. Metadata including packetization mapping information, missing packets not received by the receiving device, and reproduction time at the receiving device are also uploaded to the storage device. The storage device stores the missing packets and reproduction time of each receiving device if the same media stream is received by multiple devices. The data in the storage device is used to reconstruct the received media stream and reproduce the end user experience.
