A new MD (multiple description) video coding method is proposed in this paper

which is based on balanced multiwavelet image transform. First

we apply balanced multiwavelet transform to the image

and then

corresponding components of each sub-band are gathered together

so that we decompose the image into 4 MDs. By treating every frame of the video sequences like this

we can get a theme of MD video coding. A practical MD coding theme must satisfy two requirements. Firstly

each description should carry the same amount of information. Secondly

there must be dependence among each description. We find among commonly used multiwavelets

only balanced multiwavelet can satisfy the two requirements. Furthermore

based on the feature of CARDBAL2 multiwavelet and strict mathematical deduction

we find a way to estimate the lost descriptions. The experimental results presented in this paper show that even 75% data of the image is lost

we can still get a recovered image at good quality and the PSNR value is nearly 30dB.
