This paper addresses the problem of robust decoding of 3D video over hybrid broadcast networks, using Multiple Description Coding (MDC). Despite the fact that MDC allows decoding of any description even when the others are lost in the multipath network, the resulting coarsely decoded depth maps produce unacceptable distortion in synthesised views. This is particularly harmful in the case of intra-coded...
Regular video cameras shoot normally at 25/30 frames per second (fps). Actually there are available in the market equipments that allow us to acquire video at 1.000.000 fps. When we observe a video sequence it becomes noticeable that great part of the information remains unchanged regardless of the bit rate or frame rate used. One origin of discontinuity in video signals is directly related to movement...
This paper describes a linear interpolation algorithm and compares it with the discrete Papoulis-Gerchberg applied to voice signal reconstruction. The simulation results, measured as reconstruction time and signal accuracy, show that such method achieves good results. By combining the proposed algorithm with a proper packetisation scheme, it may be useful in VoIP communications.
