With the development of communications and network technologies, video streaming service is becoming increasingly important. However, in the transmission of high compressed video, bit-stream is easily damaged by channel errors which will lead to the decline of the video sequence. Error concealment is an effective approach to reduce the influence in error-prone network and notably improve the video...
In real-time video transmission over error-prone network, the packet loss cannot be avoided which causes the video quality reduction in the destination. In this paper, we propose a pervasive temporal error concealment (PTEC) algorithm for H.264/AVC Inter frame decoding to eliminate the error effect for Human Visual System (HVS). To increase the error concealment (EC) accuracy, the 4x4 block size is...
Recently H.264/AVC is rapidly deployed in the mobile multimedia market, such as terrestrial and satellite DMB (digital multimedia broadcasting), and Internet multimedia streaming systems. To provide the better quality under the unreliable communication environments, we propose a motion vector (MV) recovery method for the temporal error concealment. The H.264/AVC adopts the various block sizes for...
In this paper, a temporal error concealment method for the H.264 is presented, which uses the high correlation between the motion vectors of neighboring blocks. By using the motion vectors of neighboring macroblock of the lost MB, the motion vectors of the lost MB are recovered. Simulation result shows that the proposed method yields better subjective and objective quality than conventional methods.
