Self-Describing Error Correction of Consolidated Media Content

摘要

Presented herein are downstream recovery (error correction) techniques for an aggregated/consolidated media stream. In one example, a consolidated media stream that includes source media packets from one or more sources is sent to one or more downstream receiving devices. Based on the source media packets, one or more self-describing recovery packets for downstream error correction of the source media packets are generated. The self-describing recovery packets include a mapping to the source media packets used to generate the self-describing recovery packets, thereby avoiding the addition of error correction information in the consolidated media stream. The one or more self-describing recovery packets are sent to each of the downstream receiving devices as a separate stream.

1. A method comprising:
obtaining one or more source media packets; sending, to at least one downstream receiving device, a consolidated media stream that includes the source media packets and no error correction overhead; generating, based on the source media packets, one or more self-describing recovery packets for downstream error correction of the source media packets, wherein the self-describing recovery packets include a mapping to the source media packets used to generate the self-describing recovery packets to avoid the addition of error correction overhead to the source packets of the consolidated media stream; and sending the one or more self-describing recovery packets to the downstream receiving device.
