Distributed video coding (DVC) is an important topic for emerging applications, for example visual sensor networks and mobile video streaming. However, the major handicap applying DVC for real world applications is still the mandatory feedback channel. In previous approaches, the rate allocation algorithm was relying on feedback channel data. Commonly bit plane by bit plane decoding is done in a turbo code-based Slepian-Wolf decoder. In this paper inter bit plane decoding replaces the conventional method. The proposed inter bit plane decoding facilitates the rate control, whereas only the sum data rate has to be estimated/requested but not the data rate for each bit plane. This is one step forward to distributed video coding systems free of feedback channels.
