“…However, while many authors have proposed to design MD codecs from scratch, others have pointed out that an MD codec based only on pre-and post-processing, with the use of legacy coders, reduces significantly the development time, hence the development cost [5][6][7], even though it may come at the price of sub-optimal performance. Within this context, we recently proposed an MDC scheme for double description coding which is entirely based on pre-and postprocessing [8].…”

Abstract-Multiple description coding (MDC) is a framework designed to improve the robustness of video content transmission in lossy environments. In this work, we propose an MDC technique using a legacy coder to produce two descriptions, based on separation of even and odd frames. If only one description is received, the missing frames are reconstructed using temporal high-order motion interpolation (HOMI), a technique originally proposed for distributed video coding. If both descriptions are received, the frames are reconstructed as a block-wise linear combination of the two descriptions, with the coefficient computed at the encoder in a RD-optimised fashion, encoded with a contextadaptive arithmetic coder, and sent as side information. We integrated the proposed technique in a mobile ad-hoc streaming protocol, and tested it using a group mobility model. The results show a non-negligible gain for the expected video quality, with respect to the reference technique.

“…Aside with techniques which aim to design a MD coder exnovo, Shirani et al [6], [7] pointed out that an MD coder based only on pre-/post-processing and use of legacy coders reduces significantly the development time, hence the development cost. However, this benefit comes at the price of sub-optimal performance with respect to the from-scratch solutions.…”

Abstract-Multiple description coding is a framework adapted to noisy transmission environments. In this work, we use H.264 to create two descriptions of a video sequence, each of them assuring a minimum quality level. If both of them are received, a suitable algorithm is used to produce an improved quality sequence. The key technique is a temporal image interpolation using motion compensation, inspired to the distributed video coding context. The interpolated image blocks are weighted with the received blocks obtained from the other description. The optimal weights are computed at the encoder and efficiently sent to the decoder as side information. The proposed technique shows a remarkable gain for central decoding with respect to similar methods available in the state of the art.
