Bit Allocation for Interframe Video Coding Systems

Bit Allocation for Interframe Video Coding Systems

ETRI Journal, Volume 24, Number 4, August 2002 In this work, we present a novel approach to the bit allocation problem that aims to minimize overall distortion subject to a bit rate constraint. The optimal solution can be found by the Lagrangian method with dynamic programming. However, the optimal bit allocation for block-based interframe coding is practically unattainable because of the inter...

Perceptual bit allocation for MPEG-2 CBR video coding

Optimal Bit Allocation for MPEG-4 Video Coding

In this paper, we propose an optimal bit allocation scheme for MPEG-4 video coding. In the proposed scheme, we assign more bits to I-frames and some selected P-frames. In order to decide optimal target bits for each intra frame, we need to calculate spatial complexity of the intra frame. We also define an absolute temporal correlation factor to measure temporal correlation between successive fr...

Bit allocation for joint source/channel coding of scalable video

We propose an efficient bit allocation algorithm for a joint source/channel video codec over noisy channels. The approach is to distribute the available source and channel coding bits among the subbands in such a way that the expected distortion is minimized. The constructed distortion curves bound the performance degradation should the channel be estimated incorrectly. The algorithm can be use...

Optimal Bit Allocation Strategy for Joint Source/channel Coding of Scalable Video Committee in Charge: Optimal Bit Allocation Strategy for Joint Source/channel Coding of Scalable Video Optimal Bit Allocation Strategy for Joint Source/channel Coding of Scalable Video

We propose an optimal bit allocation strategy for a joint source/channel video codec over noisy channel when the average channel state is assumed to be known. Our approach is to partition source and channel coding bits in such a way that the expected distortion is minimized. The particular source coding algorithm we use is rate scalable and is based on 3D subband coding with multi-rate quantiza...
