Enhanced prediction for motion estimation in Scalable Video Coding
In this paper, we present a temporal candidate generation scheme that can be applied to motion estimators in Scalable Video Codecs (SVCs). For bidirectional motion estimation, usu...

An extension of direct macroblock coding in Predictive (P) slices of the H.264 standard
The consideration of better motion compensation techniques for inter-frame prediction is one of the key reasons why the new H.264 (MPEG-4 AVC) video coding standard can achieve co...

Reduced Frame Quantization in Video Coding
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation ...

Error Concealment for INTRA-Frame Losses over Packet Loss Channels
In this paper, we propose an Error Concealment algorithm for INTRA-frame losses over packet loss channels. The novelty is that not only the INTRA-frame but also the subsequent INTE...
