“…Improving the Coding Efficiency and Improving the RD Performance of the System. Multiple description coding [20][21][22][23][24][25][26] and redundant image [27][28][29] techniques are also effective against channel transmission errors, but both come at the cost of increased bit consumption. The video errorresilience technology in the video compression algorithm needs to consume a part of the code stream so that the sender has to generate more data transmission to ensure the same reconstruction quality in the decoder.…”

Limited by the characteristics of underwater acoustic channels, the video transmission applications targeting deep-sea detection and operation tasks are facing severe challenges such as network failure and high delay, resulting in loss of video details, color distortion, blurring, and even bit errors, which seriously affect decoding quality of the video transmission and reception. In order to solve the problems of deep-sea long-distance wireless communication, this paper proposes an improved Wyner-Ziv coding scheme (UnderWater-WZ) for video transmission through acoustic channels. The implementation process includes controlling error range by using MJPEG coding, combining motion compensation time interpolation with calibration information to generate high-quality side information. And intraframe quantization matrix is designed to weaken the change of video scene. The experimental results show that under the highest packet loss rate of 20%, this scheme can achieve 2.6~3.5 dB improvements in terms of video reconstruction compared to the previous methods, which is close to the error-free level.

“…With these parameters, we assume that the contributions of spatial and temporal concealment errors to the total concealment error (denoted byǫ 2 c ) are separable. We assume this because for each lost MB, only one type of concealment is used [12].…”

“…This error depends on the codec and its parameters, the packetization strategy, the decoder error concealment and the video content [11]. A flexible redundancy allocation framework, based on an end-to-end distortion model for three loop, two description MDC is presented in [12]. However, this method requires the presence of a reliable backward channel to feed back the PLRs to the encoder.…”

Multiple Description Coding (MDC) is an error resilient video coding method suitable for real-time applications when retransmission is unacceptable. A four description MDC architecture is described with temporal and spatial error concealment capabilities at the decoder. In this paper, we present an adaptive error concealment method using error estimation. Experimental results demonstrate the efficacy of the proposed method.
