Abstract:
1. A method in a distortion calculator computer for estimating distortion for an inter-coded image, comprising: accessing with the distortion calculator computer an average channel distortion estimated for a previously coded image; and calculating with the distortion calculator computer an average channel distortion for the inter-coded image as said average channel distortion estimated for the previously coded image scaled by a scaling factor (1-P)(a(1−β)+β)+hP, where P represents a packet loss rate, β represents an intra rate, a is a parameter associated with inter-prediction, c is a parameter associated with intra-prediction, and h is a parameter associated with concealment, where: the inter-coded image is encoded with inter-prediction and temporal concealment with non-integer motion vectors, and without intra-prediction and deblocking filtering, the inter-coded image is encoded with inter-prediction and temporal concealment with non-integer motion vectors, with intra-prediction, and without deblocking filtering, or the inter-coded image is encoded with inter-prediction and temporal concealment with non-integer motion vectors, and with intra-prediction and deblocking filtering.
