Abstract

This paper proposes two encoding methods for discardable slices in scalable video coding. Discardable slices are not used for inter-layer prediction and can therefore be removed from a coded bitstream from layers below the decoded scalable layer. Consequently, discardable slices need not be transmitted when the layer that the receiver decodes is known by the sender. The potential bit rate saving compared with conventional scalable coding makes the use of discardable slices an attractive encoding strategy, e.g. for unicast streaming applications. Among the two proposed encoding algorithms, one is a two-pass encoding method and the other models the coding problem as a Knapsack Problem (KP). Performed simulations indicate improved rate-distortion performance.
