This study presents an intensity gradient approach for intra-prediction in H. 264 encoding
system, which enhances the performance and efficiency of previous fast algorithms. We …

A method of scaling complexity of a video processing system including determining a power
saving factor based on an operating parameter and adjusting processing of video …

The recently approved digital video standard known as H. 264 promises to be an excellent
video format for use with a large range of applications. Real-time encoding/decoding is a …

Reversible watermarking algorithms make it possible that the original image can be totally
restored after the watermark was extracted, so it is widely used in the protection of …

The paper presents a VLSI prototype for context-based adaptive variable length coding
(CAVLC). This scheme is a part of the lossless compression process in the MPEG-4 Part 10 …

This paper presents a hardware prototype of the H. 264 transformation. The proposed
architecture uses only add and shift operations to reduce the computational requirements for …

Thanks to many novel coding tools, H. 264/AVC has become the most efficient video
compression standard providing much better performance than previous standards …

In broadcast and multicast systems, video programs are transmitted over a constant bit rate
channel. Apart from bandwidth constraints, the control of each encoder involved in the …

This paper presents a VLSI prototype for the 2times2 Hadamard transform that is applied to
the DC coefficients of the four 4times4 blocks of each chroma component as described in the …

In this paper, we present a low cost Forward Transform and Quantization (FTQ)
implementation for H. 264/AVC encoders in mobile applications. To reduce the hardware …
