The environment of transmission via a wireless network is not always error-free. The loss of data or impairment caused by errors degrades the quality of image. The error concealment is the method that finds the best substitute information from the previous reference image with the boundary information around lost block. Therefore, This paper proposes an(More)
To transmit video bit stream over low bandwidth such as mobile channel, high bit rate algorithm like H.264/AVC codec is exploited. In transmitting high compressed video bit-stream over low bandwidth, packet loss causes severe degradation in image quality. In this paper, a new error concealment algorithm for recovery of missing or erroneous motion vector is(More)
On the channel of wireless transmission environment, there is the data loss suffered from a packet loss. A packet loss brings lowering of image quality of the decoded image. Error concealment method is the efficient method that reduces lowering of performance in having error. This study introduces a method of Adaptive MultiSide Boundary Matching(More)
