Abstract

This work deals with dropped streaming video packets from the viewpoint of minimizing future dropped packets, as well as restoring data lost in packets already dropped, specifically geared toward real-time transmission of H.263+ bitstream. Minimization of future dropped packets is achieved by an adaptive least mean squares bandwidth (BW) controller predicting the available bandwidth supported by the Internet with relatively little loss. Restoration of lost video data is performed by a combination of error concealment (EC) techniques, including interpolation of border pixels in DCT domain. All algorithms presented are computationally inexpensive and thus suited for real-time video applications
