Abstract:
The new video applications, such as video conference over wireless networks, video
surveillance, PC cameras and mobile phones suffer from computation and energy resources
limitation. In this context, the conventional predictive coding is not effective because its
encoder is very complex. For this, it is more interesting to use low-complexity video
encoders. To meet these requirements, the distributed video coding was developed having a
low complexity at the encoder.
Our contribution is the implementation of practical surveillance system, using distributed
video coding and running on the wireless (WIFI) network. We have implemented all the
operations of encoding, decoding and communication protocol between the encoder and
decoder to manage the information’s exchange. We have also proposed some techniques to
speed up the system, particularly for the creation of the side information and rate
management.
