Improved H.264 rate control by enhanced MAD-based frame complexity prediction
This paper presents a revised rate control scheme based on an improved frame complexity measure. Rate control adopted by both MPEG-4 VM18 and H.264/AVC use a quadratic rate-distor...

Mixed-resolution distributed video codec without motion estimation at the encoder
Inspired by recent results showing that Wyner-Ziv coding using a combination of source and channel coding may be more efficient than pure channel coding, we have applied coset cod...

Laplacian Distortion Model (LDM) for Rate Control in Video Coding
Abstract. In many rate control models, a uniform weighted distortion has been assumed; that is, the DCT coefficients of the motioncompensation difference frames (residues) conform...

A multi-hypothesis decoder for multiple description video coding
— Multiple Description Coding (MDC) can be used as an Error Resilience (ER) technique for video coding. In case of transmission errors, Error Concealment (EC) can be combined wit...
