Channel adapted scan-based multiple description video coding
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 609-612 vol.2
Tóm tắt
In Pereira et al. (2002) we proposed a balanced multiple description coding (MDC) scheme based on the discrete wavelet transform (DWT). This MDC includes an efficient bit allocation procedure that dispatches the source image redundancy between different channels. The amount of redundancy is controlled according to the bit error rate of the different channels. Here, we propose to extend this approach for low bit rate video transmission. The proposed method uses the 3D scan-based DWT of Parisot et al. (2000) and involves scan-based MDC with rate or quality control.
