Large external memory bandwidth requirement leads to increased system power dissipation
and cost in video coding application. Majority of the external memory traffic in video encoder …

Frame recompression is an efficient way to reduce the huge bandwidth of external memory
for video encoder, especially for P/B frame compression. A novel algorithm, which is called …

Handheld battery-operated consumer electronics video devices such as camera phones,
digital still cameras, digital camcorders, and personal media players have limited system …

Hybrid video compression schemes such as MPEG2 and H. 263 use an image memory for
motion-compensated coding. In VLSI implementations, this image is usually stored in …

We propose a novel variable bit rate (VBR) algorithm that adopts two-pass encoding to
implement high-performance coding for fixed-size storage applications. In the first-pass …

Motion estimation and motion compensation in HEVC and similar video codecs involve
huge memory traffic in storing and loading reference frames. The resulting memory power …

All motion-vectors are encoded with the same tired accuracy, typically 1/2-pixel accuracy,
but the best motion-vector accuracies are not known. We present a theoretical framework to …

We make a case that taking the number of bits to code each motion vector into account when
estimating motion for video compression results in significantly better performance at low bit …

Owing to the huge bandwidth requirement, the DRAM power composes a significant portion
of the power consumed by video coding system. In this paper, a lossless frame …

In high definition video decoders for the standard like H. 264, bandwidth requirement is a
critical design issue due to the overwhelming amount of memory data access. This paper …
