Video transmission over unreliable networks introduces new challenges in video coding. Due to the predictive coding techniques, the effect of channel errors on the decoded video can be extremely severe when the compressed video is transmitted over error-prone channel. In this paper, the problem of scalable video transmission over error-prone channel is addressed. It is proposed to selectively add...
This paper presents a CMOS image sensor with focal-plane compression. The design has a column-level architecture and it is based on predictive coding techniques for image decorrelation. The prediction operations are performed in the analog domain to avoid quantization noise and to decrease the area complexity of the circuit. The prediction residuals are quantized and encoded by a joint quantizer/coder...
