Description: Low-rate video is widely used especially in mobile communications.
H.264/AVC (advanced video coding) is well suited
for the real-time error resilient transport over packet oriented
networks. In real-time communications, lost packets at the
receiver cannot be avoided. Therefore, it is essential to design
efficient error concealment methods which allow to visually
reduce the degradation caused by the missing information.
Each method has its own quality of reconstruction.
We implemented various efficient error concealment techniques
and investigated their performance in different scenarios.
As a result, we propose and evaluate an adaptive error
concealment mechanism that accomplishes both - good
performance and low complexity enabling the deployment
for mobile video streaming applications. This mechanism
selects suitable error concealment method according to the
amount of instantaneous spatial and temporal information of
the video sequence.
