Frame-Based Multiple-Description Video Coding with Extended Orthogonal Filter Banks

Frame-Based Multiple-Description Video Coding with Extended Orthogonal Filter Banks

We propose a frame-based multiple-description video coder. The analysis filter bank is the extension of an orthogonal filter bank which computes the spatial polyphase components of the original video frames. The output of the filter bank is a set of video sequences which can be compressed with a standard coder. The filter bank design is carried out by taking into account two important requireme...

Filter banks for multiple description coding

In this paper we review some of our recent results on the design of critically sampled and oversampled filter banks for multiple description coding. For the case of critically sampled filter banks, we show that optimal filters are obtained by allocating the redundancy over frequency with a reverse ’water-filling’ strategy. Then we present families of oversampled filter banks that attain optimal...

Optimal filter banks for multiple description coding: Analysis and synthesis

Multiple description (MD) coding is a source coding technique for information transmission over unreliable networks. In MD coding, the coder generates several different descriptions of the same signal and the decoder can produce a useful reconstruction of the source with any received subset of these descriptions. In this paper, we study the problem of MD coding of stationary Gaussian sources wi...
