Video Adaptation. Furht, B., editor In Encyclopedia of Multimedia, pages 890–891. Springer US, 2008. 00005

SynonymsFrame droppingDefinitionVideo adaptation is a way to process video contents originally designed for a particular device or platform to fit in other devices or platforms.Adaptation operations are performed on the original encoded media in order to match resource constraint (e.g., bandwidth and resolution) or user preference without modality conversion (i.e. no format change will occur). Many adaptation methods exist for adjusting the bit rate of compressed video streams, for example, Frame Dropping, DCT coefficients dropping etc. Frame Dropping is a well-known technique for temporal adaptation. It tries to meet the desired frame rate by dropping or skipping frames in a video. A major concern in Frame Dropping technique is that if an anchor/reference frame (I-frame or P-frame) is dropped, subsequent frames may need to be re-encoded to avoid error propagation (see Fig. 1). DCT co-efficient dropping is another common technique to adjust the spatial quality of each ...
