Title: Pet - Priority Encoded Transmission
Author: B. Lamparter, A. Albanese, M. Kalfane, and M. Luby
Group: ICSI Technical Reports

Overview:
This paper presents a new Forward Error Correction scheme with several priority levels. It is useful for applications dealing with real-time transport streams like video and audio. Those streams consist of several data parts with different importance. PET allows to protect those parts with appropriate redundancy and thus guarantees, that the more important parts arrive before the less important ones. In the video we show the impacts of losses to an MPEG video stream with and without PET protection. Due to the fragile nature of MPEG the unprotected stream breaks up, the PET protected stream is unaffected by low losses and jerky when high losses are present.
