Abstract
This paper presents the Heuristic Application Layer Joint Coding (Heuristic-ALJC) scheme for video transmissions aimed at adaptively and jointly varying both applied video compression and source encoding at the application layer used to protect video streams. Heuristic-ALJC includes also a simple acknowledgement based adaptation of the transmission rate and acts on the basis of feedback information about the overall network status estimated in terms of maximum allowable network throughput and link quality (lossiness). Heuristic-ALJC is implemented through two smartphone Apps (transmitter and receiver) and is suitable to be employed to transmit video streams over networks based on time varying and possibly lossy channels. A performance investigation, carried out through a real implementation of the Apps over Android smartphones, compares Heuristic-ALJC with static schemes.
