Title
an improved H.264 error concealment algorithm with user feedback design
Abstract
This paper proposes a new Error Concealment (EC) method for the H.264/AVC [1] video coding standard using both spatial and temporal information for intra-frame concealment. Five error concealing modes are offered by this method. The proposed EC method also allows feedback from users. It allows users to define and change the thresholds for switching between five different modes during the error concealing procedure. As a result, the concealing result for a video sequence can be optimized by taking advantage of relevant user feedback. The concealed video quality has been measured by a group of users and compared with the H.264 EC method which is without user feedback. The experimental results show that the proposed new EC algorithm with the user feedback performs better (3 dB gains) than the H.264 EC without user feedback.
