Network aware video transcoding for symbiotic rate adaptation on interactive transport

Abstract

The authors present a potential new approach of application integrated congestion management. It is applicable for time-sensitive traffic and is based on the principle of direct protocol interactivity. In contrast to classical transport protocols, we envision a transport mechanism which is interactive and can provide event notification to the subscriber of its communication service. We then show a network aware adaptive MPEG-2 video transcoding mechanics, which directly interacts with the protocol and adjusts its production in sync with the impairment events in the transport layer. The authors present the novel symbiotic mechanics, and share the performance result observed on the MPEG-2 video stream carried by this symbiosis implementation. We report dramatic improvement in time-conformant video delivery by such protocol interactivity.
