We address the problem of improving the scene cut quality in fixed bit-rate real-time video decoding such as is used in the H.263 and MPEG standards. In low bandwidth applications, scene cuts can cause the bits required to encode a single frame to greatly exceed the target average bits per frame, and necessitate the skipping of other frames to provide sufficient time to transmit the scene cut frame. We present an optimal algorithm for minimizing the number of skipped frames and keep the decoding synchronized. Although the algorithm requires additional encoding complexity, there is no change in decoding complexity (in fact, no change to the decoder at all). Experimental results, obtained with a simplified strategy within the framework of H.263+ video encoding, confirm that the method provides an effective alternative to current frame skipping strategies. The overall quality in the presence of scene cuts is improved with respect the TMN-8 rate control. Although the overall bit rate benefits from our method, our focus is to improve the quality of the video where scene cuts occur (by reducing skipped frames and improving decoder synchronization). The approach here can be combined with more sophisticated rate controls, as, for example, the newer rate-distortion optimized TMN-10 and TMN-11
