In this paper a novel methodology for temporal scalability within the H.263 video coding standard is presented. Temporal scalability is defined as the transmission of previously dropped frames in the form of a scalable enhancement layer to increase the overall encoded frame rate. The proposed methodology extends the base layer rate control to the enhancement layer and incorporates an adaptive technique for enhancement layer frame selection. Three criteria important in the selection of enhancement frames are identified, allowing us to adaptively choose frames such that the overall temporal resolution of the encoded video sequence is enhanced. Experimental results are provided and compared to a non-adaptive technique where enhancement frames are selected solely on the decay of the enhancement layer buffer.
